混凝土樁及複合式混凝土樁Concrete pile and composite concrete pile

本新型是有關於一種基礎樁,特別是指一種使用於建築工程和結構工程的混凝土樁及複合式混凝土樁The present invention relates to a foundation pile, in particular to a concrete pile and a composite concrete pile used in construction engineering and structural engineering.

興建大型或高層建築物時,如果遭遇地層強度不足或鬆軟土層時,往往需應用置入地面下的基礎樁將上層之建築物的載重傳遞至土壤承載層或較堅硬的地盤,以增加建築物結構的安全性及穩定性。其中,又以預應力混凝土管樁為工程市場中最常見的樁型式。When constructing large or high-rise buildings, if there is insufficient stratum strength or soft soil layer, it is often necessary to apply the foundation pile placed under the ground to transfer the load of the upper building to the soil carrying layer or the harder ground to increase the building. The safety and stability of the structure. Among them, prestressed concrete pipe piles are the most common pile type in the engineering market.

參閱圖1、2,現有預應力混凝土管樁1包括一個以混凝土所製成且環繞界定出一內孔111的混凝土樁壁11、兩個分別位於該混凝土樁壁11兩相反端且能與該內孔111相連通的環狀端板12、多數兩端分別嵌設於所述環狀端板12中且沿該混凝土樁壁11縱向延伸的異形鋼棒13,及一沿該混凝土樁壁11縱軸向全長且纏繞所述異形鋼棒13之外的螺旋鋼線14。Referring to Figures 1 and 2, the existing prestressed concrete pipe pile 1 comprises a concrete pile wall 11 made of concrete and surrounding an inner hole 111, two of which are respectively located at opposite ends of the concrete pile wall 11 and can An annular end plate 12 communicating with the inner hole 111, a plurality of outer ends respectively embedded in the annular end plate 12 and extending along the longitudinal direction of the concrete pile wall 11, and a concrete beam wall 11 along the concrete pile wall 11 The longitudinal direction of the longitudinal axis and the spiral steel wire 14 outside the profiled steel bar 13 are wound.

在實務應用上,該螺旋鋼線14的纏繞間距在該預應力混凝土管樁1的兩端頭段是較小的,一般約在間距5至10厘米(cm),而在該預應力混凝土管樁1的中間段是較 大的,一般約在間距10至30厘米(cm),這是配合結構設計所需,以加強該預應力混凝土管樁1接近端頭部位的強度,並能兼顧成本。所述異形鋼棒13通常有施加先拉式預應力,以增加該預應力混凝土管樁1的強度及耐久性。In practical applications, the winding pitch of the spiral steel wire 14 is small at both ends of the prestressed concrete pipe pile 1, generally about 5 to 10 centimeters (cm) apart, and the prestressed concrete pipe The middle section of pile 1 is Large, generally about 10 to 30 centimeters (cm) apart, is required to match the structural design to enhance the strength of the prestressed concrete pipe pile 1 near the end and to take into account the cost. The profiled steel bar 13 typically has a pre-tensioned prestress applied to increase the strength and durability of the prestressed concrete pipe pile 1.

施加於該預應力混凝土管樁1的樁頂的作用力,傳遞至樁頂的該端板12或所述異形鋼棒13,再傳遞至該預應力混凝土管樁1的下方。而該螺旋鋼線14除了用以承受該混凝土樁壁11所受的水平剪力外,也能提供所述異形鋼棒13的側向支撐。The force applied to the pile top of the prestressed concrete pipe pile 1 is transmitted to the end plate 12 of the pile top or the profiled steel rod 13 and then to the underside of the prestressed concrete pipe pile 1. The spiral steel wire 14 can provide lateral support of the profiled steel bar 13 in addition to the horizontal shear force experienced by the concrete pile wall 11.

現有預應力混凝土管樁1多是預先在工廠中製作,再以車輛載運到施工處,礙於製作模具以及載運車輛的長度限制,因此,現有預應力混凝土管樁1的長度大多在8至18米(m)之間。若是需置入地面下之該預應力混凝土管樁1的深度超過一支預應力混凝土管樁1的長度時,即必需接合多數支預應力混凝土管樁1,以達到所需的土層深度需求。Most of the existing prestressed concrete pipe piles are pre-made in the factory and then transported to the construction site by vehicles. Due to the length limitation of the molds and the vehicles, the existing prestressed concrete pipe piles 1 are mostly 8 to 18 in length. Between meters (m). If the depth of the prestressed concrete pipe pile 1 to be placed under the ground exceeds the length of one prestressed concrete pipe pile 1, it is necessary to join a plurality of prestressed concrete pipe piles 1 to achieve the required soil depth requirement. .

參閱圖3,現有預應力混凝土管樁1較為常見的接合是利用銲接方式銲合兩個上、下疊置之預應力混凝土管樁1的端板12,以結合成為更長的樁,延長預應力混凝土管樁1的整體長度。上下疊置二預應力混凝土管樁1間的結合,是依賴二預應力混凝土管樁1接合處的端板12的銲合結合,或依賴其他機械螺栓接合或插栓接合的方式達成。由於這些兩預應力混凝土管樁1間的結合方式乃是目前土木工程工地上普遍施行的方式,且不在本新型專利申 請範圍,在此不多作敘述。Referring to Fig. 3, the more common joint of the existing prestressed concrete pipe pile 1 is to weld the two end plates 12 of the prestressed concrete pipe pile 1 which are superposed and superposed by welding, so as to be combined into a longer pile, and the extension is extended. The overall length of the stressed concrete pipe pile 1. The combination of the two prestressed concrete pipe piles 1 is superimposed on the welded joint of the end plates 12 at the joint of the two prestressed concrete pipe piles 1, or by other mechanical bolting or plug engagement. Because the combination of these two prestressed concrete pipe piles 1 is a common method on the current civil engineering site, and is not in the patent application. Please range, not to mention here.

大家都知道,該銲接處100的結構強度較為脆弱,而且該銲接處100又長期曝露於地下土壤或地下水的環境中,而所述端板12都是鋼製品,容易發生鏽蝕而影響接合強度與耐久性。一旦該銲接處100發生鏽蝕,就會造成相互接合之預應力混凝土管樁1的承載力減損甚至喪失,進而導致所述預應力混凝土管樁1上方的建築物遭到損壞。也由於現有的預應力混凝土管樁1接樁處的缺失,因此,現有預應力混凝土管樁1在重要結構物的使用上是受到工程界的極大的疑慮和使用限制。As we all know, the structural strength of the welded joint 100 is relatively weak, and the welded joint 100 is exposed to the environment of underground soil or groundwater for a long time, and the end plate 12 is a steel product, which is prone to rust and affects the joint strength and Durability. Once the weld 100 is rusted, the bearing capacity of the mutually joined prestressed concrete pipe pile 1 is degraded or even lost, thereby causing damage to the building above the prestressed concrete pipe pile 1. Because of the lack of existing prestressed concrete pipe piles 1 , the existing prestressed concrete pipe piles 1 are greatly doubted and used by the engineering community in the use of important structures.

參閱圖4,兩相互上下疊置銲接的預應力混凝土管樁1是透過樁頭處理方法以連結一基礎承台A。所述樁頭處理方法是將多數樁頭錨定鋼筋101置入位於圖4中上方之該預應力混凝土管樁1的頂部的內孔111約1.5至3米(m)深後,再填入膨脹混凝土102以錨定所述樁頭錨定鋼筋101。Referring to Fig. 4, two prestressed concrete pipe piles 1 welded one on top of the other are connected to a foundation cap A by a pile head treatment method. The pile head processing method is to place a plurality of pile head anchoring steel bars 101 into the inner hole 111 at the top of the prestressed concrete pipe pile 1 located above in FIG. 4, about 1.5 to 3 meters (m) deep, and then fill in The expanded concrete 102 anchors the pile head to anchor the reinforcing bars 101.

利用部分或全部凸出該預應力混凝土管樁1頂部的所述樁頭錨定鋼筋101以連結該基礎承台A。而乾硬後的該膨脹混凝土102,就會和位於圖4中上方之該預應力混凝土管樁1的該混凝土樁壁11產生摩擦力,將由所述樁頭錨定鋼筋101所傳遞下來的力量再傳遞至該混凝土樁壁11。但是,僅以該膨脹混凝土102與該混凝土樁壁11間之摩擦力以固定所述樁頭錨定鋼筋101,容易因長期受力搖晃的反覆作用,或受到地下土壤和地下水環境的影響使得該膨脹混凝土102磨損或老化而發生鬆脫現象,造成該膨脹 混凝土102與該混凝土樁壁11間接合的結構強度不足。因此,無法用於安全要求較嚴格或使用壽命要求較長的結構工程上。The pile head anchoring steel 101 is partially or entirely protruded from the top of the prestressed concrete pipe pile 1 to join the foundation platform A. The dry and expanded concrete 102 will generate friction with the concrete pile wall 11 of the prestressed concrete pipe pile 1 located above the upper part of FIG. 4, and the force transmitted by the pile head anchoring steel 101 will be transmitted. It is transferred to the concrete pile wall 11. However, only the friction between the expanded concrete 102 and the concrete pile wall 11 is used to fix the pile head anchoring steel 101, which is easy to be affected by the long-term stress shaking or affected by the underground soil and groundwater environment. The expanded concrete 102 is worn or aged and loosens, causing the expansion The structural strength of the joint between the concrete 102 and the concrete pile wall 11 is insufficient. Therefore, it cannot be used in structural engineering with strict safety requirements or long service life requirements.

舉例來說,將多數樁頭錨定鋼筋101置入一外徑60厘米(cm)、內徑40厘米的預應力混凝土管樁1樁頂部之內孔111內2米深,並填灌膨脹混凝土102。該膨脹混凝土102和該混凝土樁壁11間的長期有效摩擦力強度大約是2kg/cm2 。而埋置在該膨脹混凝土102中的所述樁頭錨定鋼筋101僅能承受=接觸面周長*長度*容許應力=(π*40cm)*200cm*2kg/cm2 =50240kg約50噸的力量。當來自上方的基礎承台A的力量超出該容許力量50頓時,就可能會發生該預應力混凝土管樁1和該基礎承台A間的接頭鬆脫的情形,進而危及該預應力混凝土管樁1上方的建築物安全。For example, a majority of the pile anchored steel bars 101 are placed into an inner hole 111 of the top of a pile of a prestressed concrete pipe pile having an outer diameter of 60 cm (cm) and an inner diameter of 40 cm, and a depth of 2 m is filled, and the expanded concrete is filled. 102. The long-term effective frictional strength between the expanded concrete 102 and the concrete pile wall 11 is about 2 kg/cm 2 . The pile head anchoring steel 101 embedded in the expanded concrete 102 can only withstand = contact surface circumference * length * allowable stress = (π * 40cm) * 200cm * 2kg / cm 2 = 50240kg about 50 tons power. When the force from the upper base cap A exceeds the allowable force by 50 ton, the joint between the prestressed concrete pipe pile 1 and the foundation cap A may be loosened, thereby jeopardizing the prestressed concrete pipe pile. 1 The building above is safe.

參閱圖5,另一種與圖4相似之兩相互銲接的預應力混凝土管樁1。差別在於,位於下方之該預應力混凝土管樁1的一端是呈尖錐狀,以便利用打樁機(圖未示)直接將所述預應力混凝土管樁1直接打擊入地下土層。這是普遍應用在預應力混凝土管樁1的錘擊式或壓入式施工的方式。與圖4所示的預應力混凝土管樁1一樣,有著銲接處100容易鬆脫的相同缺失。Referring to Figure 5, another two pre-stressed concrete pipe piles 1 which are similar to those of Figure 4 are welded. The difference is that the one end of the prestressed concrete pipe pile 1 located below is tapered, so that the prestressed concrete pipe pile 1 can be directly struck directly into the subterranean soil by a pile driver (not shown). This is a method of hammering or press-in construction commonly used in prestressed concrete pipe piles 1. As with the prestressed concrete pipe pile 1 shown in Fig. 4, there is the same lack of the weld 100 being easily released.

為了改善上述預應力混凝土管樁1的缺點,工程界業者研發出如圖6所示中華人民共和國第CN102953375B號專利的預應力混凝土管樁1’。其改善之 處在於:該預應力混凝土管樁1’在鄰近該混凝土樁壁11兩開口端112的內孔111中間隔設置多個強化單元15。每一強化單元15包括相互交疊而概呈十字形地位於該內孔111中的一第一金屬件151與一第二金屬件152。所述第一金屬件151與第二金屬件152是竹節鋼筋。In order to improve the shortcomings of the above-mentioned prestressed concrete pipe pile 1, the engineering industry has developed a prestressed concrete pipe pile 1' as shown in Fig. 6 of the Patent No. CN102953375B of the People's Republic of China. Its improvement The prestressed concrete pipe pile 1' is provided with a plurality of reinforcing units 15 spaced apart in the inner hole 111 adjacent to the two open ends 112 of the concrete pile wall 11. Each of the reinforcing units 15 includes a first metal member 151 and a second metal member 152 which are overlapped with each other and are substantially cross-shaped in the inner hole 111. The first metal piece 151 and the second metal piece 152 are bamboo reinforcing bars.

參閱圖7,實際應用時,是先在上下接合之兩預應力混凝土管樁1’之接合處103的內孔111中置入多數垂直鋼筋104並填灌填芯混凝土105;等到填芯混凝土105乾硬後,就可以利用臨近接合處103的所述強化單元15,將位於上方之該預應力混凝土管樁1’作用於所述垂直鋼筋104或樁頂112上的荷重傳遞至位於下方的預應力混凝土管樁1’,以達成荷重傳遞的目的。Referring to FIG. 7, in practical application, a plurality of vertical reinforcing bars 104 are first placed in the inner hole 111 of the joint 103 of the two prestressed concrete pipe piles 1' joined to each other and filled with the core-filled concrete 105; After the hardening, the reinforcing unit 15 adjacent to the joint 103 can be used to transfer the load of the prestressed concrete pipe pile 1' located above the vertical steel bar 104 or the pile top 112 to the pre-position below. Stress concrete pipe pile 1' to achieve the purpose of load transfer.

當進行樁頭處理作業時,則是在位於上方之該預應力混凝土管樁1’接近樁頂112的內孔111中置入多數垂直鋼筋107並填灌填芯混凝土108,等到該填芯混凝土108乾硬後,就可利用位於上方之該預應力混凝土管樁1’內的所述強化單元15,將該基礎承台A傳遞至所述垂直鋼筋107的荷重,再傳遞至該位於上方之該預應力混凝土管樁1’的該混凝土樁壁11上。When the pile head processing operation is performed, the plurality of vertical steel bars 107 are placed in the inner hole 111 of the prestressed concrete pipe pile 1' near the pile top 112 and the cored concrete 108 is filled, and the cored concrete is filled. After the dry hardening of 108, the reinforcing unit 15 in the prestressed concrete pipe pile 1' located above can be used to transfer the foundation cap A to the load of the vertical reinforcing bar 107, and then transferred to the upper portion. The prestressed concrete pipe pile 1' is on the concrete pile wall 11.

由上述可知,該基礎承台A的荷重是先作用於上方之該預應力混凝土管樁1’內的所述垂直鋼筋107與樁頂112,再經由接近該基礎承台A處的填芯混凝土108與該強化單元15傳遞至位於上方之該預應力混凝土管樁1’的該混凝土樁壁11,之後,再傳遞至位於接合處103的所述 垂直鋼筋104,然後,再經由接近該接合處103的該填芯混凝土105與該強化單元15傳遞至位於下方之該預應力混凝土管樁1’的該混凝土樁壁11上,最後,再傳遞至土層。如此,雖然可以提升接合處103與樁頭處理作業的穩定性,但是,由於所述強化單元15只設置在鄰近端口112處,不僅會導致該基礎承台A之荷重的傳遞如圖8箭頭所示過於曲折,也會形成力量傳遞的限制。It can be seen from the above that the load of the foundation cap A is the vertical steel bar 107 and the pile top 112 which are first applied to the upper prestressed concrete pipe pile 1', and then through the core-filled concrete near the foundation cap A. 108 and the reinforcing unit 15 are transferred to the concrete pile wall 11 of the prestressed concrete pipe pile 1' located above, and then transferred to the joint at the joint 103 The vertical reinforcing bar 104 is then transferred to the concrete pile wall 11 of the prestressed concrete pipe pile 1' underneath via the cored concrete 105 close to the joint 103 and the reinforcing unit 15 and finally transferred to the concrete pile wall 11 of the prestressed concrete pipe pile 1' below. Soil layer. In this way, although the stability of the joint 103 and the pile head processing operation can be improved, since the reinforcing unit 15 is disposed only at the adjacent port 112, not only the transfer of the load of the base pile A is caused by the arrow of FIG. Too much tortuousness will also form a limit on the transmission of power.

中華人民共和國第CN102953375B號專利,雖然改進了現有預應力混凝土管樁1在樁頭處理和接樁處的許多缺失,可以使用在較不重要的建築和結構工程應用上。但是,這樣曲折的力量傳遞模式,是結構工程所不易認同的,尤其是那些重大或重要的結構物,例如交通橋樑等的基礎工程。The CN102953375B patent of the People's Republic of China, although improving many of the existing prestressed concrete pipe piles 1 in the pile head treatment and the piles, can be used in less important architectural and structural engineering applications. However, such tortuous modes of power transmission are not easily recognized by structural engineering, especially those that are major or important structures, such as transportation bridges.

參閱圖9、10,日本實開昭第S38-1232號專利所公開「混凝土基礎樁的接合裝置」的技術大致是與圖7相似,差別在於:位於接合處103之補強鋼筋106的兩端是呈U字型的彎鉤狀,藉以增加握持力量以防止該補強鋼筋106被外力拔出而致失效。但是該內孔111的空間本來就十分有限,要在設置有強化單元15的該內孔111中,設置兩端呈U字型彎鉤狀的所述補強鋼筋106施工更是困難而容易導致失敗。以直徑19至25毫米(mm)的竹節鋼筋而言,若採用U字型的彎鉤,就需要大約是在155至210毫米(mm)左右的彎鉤突出尺寸,是一個相當大的尺寸,想穿入上方樁之該內孔111中呈米字型的交叉該強化單元15的 狹小空隙中,施工上的難度十分的高。Referring to Figures 9 and 10, the technique of "the joint device for concrete foundation piles" disclosed in Japanese Laid-Open Patent Publication No. S38-1232 is substantially similar to that of Fig. 7, except that the ends of the reinforcing bars 106 at the joints 103 are The U-shaped hook shape is used to increase the grip strength to prevent the reinforcing reinforcing bar 106 from being pulled out by external force and causing failure. However, the space of the inner hole 111 is inherently limited. In the inner hole 111 in which the reinforcing unit 15 is provided, it is more difficult to form the reinforcing reinforcing bar 106 having U-shaped hooks at both ends, which is easy to cause failure. . For a bamboo bar with a diameter of 19 to 25 millimeters (mm), if a U-shaped hook is used, a hook projection size of about 155 to 210 millimeters (mm) is required, which is a considerable size. The reinforcing hole 15 is crossed in the inner hole 111 of the upper pile to be inserted into the upper pile. In the narrow gap, the difficulty in construction is very high.

其次,圖9、10的施工方法是先在下方樁中先置入所述補強鋼筋106,再澆注混凝土109,待該混凝土109乾硬後,再將上方樁疊置在下方樁的上面,再澆注其上的混凝土110。Secondly, the construction method of Figs. 9 and 10 is that the reinforcing steel 106 is first placed in the lower pile, and then the concrete 109 is poured. After the concrete 109 is dry and hard, the upper pile is stacked on the lower pile, and then The concrete 110 on it is poured.

這樣的施工方式,除了所述補強鋼筋106不易插入該上方樁的該內孔111的該強化單元15的空隙中,而致失敗。該下方樁的內孔111的該混凝土109須先澆注,等待乾硬,才能施作該上方樁的部份十分耗費時間,例如此一部份即須等待3至28天的乾硬時間,會造成施工成本的高漲和工期的延宕浪費,也會造成前後期灌注的混凝土間的施工裂縫。在所述補強鋼筋106不易插入的情況,造成圖9、10所示,日本實開昭第S38-1232號專利專利所揭示的技術,不如圖7所示中華人民共和國第CN102953375B專利接樁處採用的無彎鉤設置的該垂直鋼筋104,可輕易直接插入該強化單元15的該第一金屬件151與該第二金屬件152間的空隙。Such a construction method fails in addition to the fact that the reinforcing reinforcing bar 106 is not easily inserted into the gap of the reinforcing unit 15 of the inner hole 111 of the upper pile. The concrete 109 of the inner hole 111 of the lower pile has to be poured first, and it is very time-consuming to wait for the dry pile to be applied. For example, this part has to wait for 3 to 28 days of dry and hard time. The high construction cost and the delay of construction period will also cause construction cracks between the concrete poured in the early and late stages. In the case where the reinforcing reinforcing bar 106 is not easily inserted, the technology disclosed in Japanese Patent Application Laid-Open No. S38-1232, as shown in Figs. 9 and 10, is not used as shown in Figure 7 of the Patent No. CN102953375B of the People's Republic of China. The vertical reinforcing bar 104 disposed without the hook can be easily inserted directly into the gap between the first metal member 151 and the second metal member 152 of the reinforcing unit 15.

參閱圖11,日本實開昭第S58-6841號專利所公開「含有交叉式鐵筋之已製混凝土樁」的技術則是在距離樁的端口112約50厘米處放入設有彎曲狀之交叉式鐵筋16,之後由該端口112朝樁尖18方向間隔每2米逐一放入筆直的交叉式鐵筋17,以防止發生幼兒掉落事故且提升強度。Referring to Fig. 11, the technique of "concrete concrete pile containing cross-shaped iron bars" disclosed in Japanese Laid-Open Patent Publication No. S58-6841 is to have a curved cross at a distance of about 50 cm from the port 112 of the pile. The iron bars 16 are then placed into the straight intersecting iron bars 17 one by one every 2 meters from the port 112 toward the pile tip 18 to prevent the child from falling accidents and to increase the strength.

參閱圖12,當基礎樁置入土層中,承受來自基 礎承台A的垂直壓力P和水平力V時,最常見的即是承受其組合後的綜合作用力F,最典型的破壞情形是呈現45度角的斜向破壞,常見的樁體外表是呈現45度角的斜向裂縫B。所以,由圖11所述之交叉式鐵筋16、17的設置而成為補強筋時,必須在設置在縱軸向間距S須小於樁體的外徑D,否則在45°度角的該斜向裂縫B產生時,就無法成為補強的結構機制。Referring to Figure 12, when the foundation pile is placed in the soil layer, it is subjected to the base. When the vertical pressure P and the horizontal force V of the foundation cap A are the most common ones, they are subjected to the combined force F of the combination. The most typical failure situation is the oblique damage of 45 degrees. The common external surface of the pile is An oblique crack B exhibiting a 45 degree angle. Therefore, when the reinforcing iron bars 16 and 17 are arranged as the reinforcing ribs as shown in Fig. 11, the longitudinal axial spacing S must be smaller than the outer diameter D of the pile body, otherwise the angle is 45 degrees. When it is generated to the crack B, it cannot be a structural mechanism of reinforcement.

但是,由於所述交叉式鐵筋17間的間距過大,因此,不足以作為傳遞力量的結構媒介,無法確保荷重可以完全傳遞至地下土層。而且圖11除了所述交叉式鐵筋16、17的設置外,也未見到任何補強的設計及實施例,故無從判斷圖11的補強機制。However, since the pitch between the intersecting iron bars 17 is too large, it is not sufficient as a structural medium for transmitting force, and it is impossible to ensure that the load can be completely transmitted to the underground soil layer. Moreover, in addition to the arrangement of the crossed iron bars 16, 17, no reinforcing design and embodiment are shown in Fig. 11, so the reinforcing mechanism of Fig. 11 cannot be judged.

因此,本新型之目的,即在提供一種能提升整體強度且穩定傳遞荷重的混凝土樁。Therefore, the object of the present invention is to provide a concrete pile capable of improving the overall strength and stably transmitting the load.

於是,本新型混凝土樁,包含一個形成有一沿一軸線方向延伸的通孔的樁體,及多數沿該樁體的全長間隔設置於該通孔內的水平強化機構。每一水平強化機構具有多數交叉相疊的水平強化金屬件,而且每兩相鄰的水平強化機構的間距不大於該樁體外徑的1.2倍。Accordingly, the novel concrete pile includes a pile body formed with a through hole extending in an axial direction, and a plurality of horizontal reinforcing mechanisms disposed in the through hole at intervals along the entire length of the pile body. Each horizontal reinforcing mechanism has a plurality of horizontally reinforced metal members that are interdigitated, and the spacing of each two adjacent horizontal reinforcing mechanisms is not more than 1.2 times the outer diameter of the pile.

因此,本新型的另一目的,即在提供一種能提升整體強度且穩定傳遞荷重的混凝土樁。Therefore, another object of the present invention is to provide a concrete pile capable of improving the overall strength and stably transmitting the load.

於是,本新型混凝土樁,包含一個形成有一沿一軸線方向延伸的盲孔的樁體,多數沿該樁體的全長間隔 設置於該盲孔內的水平強化機構。每一水平強化機構具有多數交叉相疊的水平強化金屬件,而且每兩相鄰的水平強化機構的間距不大於該樁體外徑的1.2倍。Thus, the novel concrete pile comprises a pile body formed with a blind hole extending in an axial direction, most of which are spaced along the entire length of the pile body. A horizontal reinforcement mechanism disposed in the blind hole. Each horizontal reinforcing mechanism has a plurality of horizontally reinforced metal members that are interdigitated, and the spacing of each two adjacent horizontal reinforcing mechanisms is not more than 1.2 times the outer diameter of the pile.

在本新型被詳細描述之前,應當注意在以下的說明內容中,類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

參閱圖13、14,本新型混凝土樁之第一實施例包含一個形成有一沿一軸線L方向延伸的通孔216的樁體21、多數沿該樁體21的全長間隔設置於該通孔216內的水平強化機構22,及分別連設於該樁體21兩端且連通該通孔216的一第一環狀開口端板23與一第二環狀開口端板24。Referring to Figures 13 and 14, the first embodiment of the present concrete pile includes a pile body 21 formed with a through hole 216 extending in the direction of the axis L, and a plurality of portions 21 are disposed in the through hole 216 at intervals along the entire length of the pile body 21. The horizontal reinforcing mechanism 22 and a first annular open end plate 23 and a second annular open end plate 24 respectively connected to the two ends of the pile body 21 and communicating with the through hole 216.

該樁體21具有一個環繞該軸線L界定出該通孔216且以混凝土製成的混凝土樁壁211、多數沿該軸線L方向延伸設置於該混凝土樁壁211的全長範圍內的軸向鋼棒214,及一在該混凝土樁壁211的全長範圍內螺旋纏繞所述軸向鋼棒214的螺旋鋼線215。所述軸向鋼棒214可以是鋼鉸線、鋼線或異形鋼棒,且可以施加先拉式預應力,以讓混凝土樁壁211的混凝土能存在預應力,增強混凝土對外界環境的抵抗力,就如同現有的預應力混凝土管樁一樣。於本實施例中,所述軸向鋼棒214是施加先拉式預應力的 異形鋼棒。The pile body 21 has a concrete pile wall 211 which defines the through hole 216 around the axis L and is made of concrete, and an axial steel rod which is mostly disposed in the entire length of the concrete pile wall 211 along the axis L direction. 214, and a spiral steel wire 215 spirally wound around the axial steel bar 214 over the entire length of the concrete pile wall 211. The axial steel bar 214 may be a steel hinge wire, a steel wire or a profiled steel bar, and may apply a pre-tensioning pre-stress to allow pre-stress of the concrete of the concrete pile wall 211 to enhance the resistance of the concrete to the external environment. Just like the existing prestressed concrete pipe piles. In the embodiment, the axial steel bar 214 is applied with a pre-tensioned prestressing force. Shaped steel rod.

每一水平強化機構22具有二交叉相疊而概呈十字型的水平強化金屬件221,每一水平強化金屬件221具有一顯露於該通孔216內的結構段222,及兩分別一體連設於該結構段222兩端且錨固於該混凝土樁壁211內的連接段223。而且每兩相鄰的水平強化機構22的間距不大於該樁體21外徑的1.2倍。Each of the horizontal reinforcing members 22 has two horizontally reinforced metal members 221 which are stacked in a cross shape. Each of the horizontal reinforcing metal members 221 has a structural portion 222 exposed in the through hole 216, and the two are integrally connected. The connecting section 223 is anchored to the concrete pile wall 211 at both ends of the structural section 222. Moreover, the spacing of each two adjacent horizontal reinforcing mechanisms 22 is not more than 1.2 times the outer diameter of the pile 21.

由於所述水平強化金屬件221的用途是將力量傳遞到兩端的混凝土樁壁211,所以所述水平強化金屬件221必須錨定在混凝土樁壁211的混凝土中。實際運用上,所述水平強化金屬件221是綁紮在所述軸向鋼棒214或該螺旋鋼線215上,以便在工廠製造混凝土樁壁211的乾硬過程中能固定所述水平強化金屬件221的位置,並非依靠該水平強化金屬件221的相互接觸來傳遞力量。所述二水平強化金屬件221交叉相疊只是方便固定該水平強化金屬件221的組立,接觸相疊並非一定是必要的,只要相接近,例如間隔5至10厘米,即可達成力量的傳遞目的,並不影響本新型的功能。Since the purpose of the horizontal reinforcing metal member 221 is to transmit the force to the concrete pile wall 211 at both ends, the horizontal reinforcing metal member 221 must be anchored in the concrete of the concrete pile wall 211. In practical application, the horizontal reinforcing metal member 221 is bound to the axial steel bar 214 or the spiral steel wire 215 to fix the horizontal reinforcing metal member during the dry process of manufacturing the concrete pile wall 211 in the factory. The position of 221 does not rely on the mutual contact of the horizontal reinforcing metal members 221 to transmit force. The two horizontal reinforcing metal members 221 are stacked and overlapped only to facilitate the fixing of the horizontal reinforcing metal members 221, and the contact stacking is not necessarily necessary, as long as the phases are close, for example, 5 to 10 cm apart, the force transmission can be achieved. Does not affect the function of this new model.

而且所述水平強化機構22的間距是與所述水平強化機構22相對於該第一環狀開口端板23及該第二環狀開口端板24的距離呈正比,也就是說,愈接近該第一環狀開口端板23或該第二環狀開口端板24之所述水平強化機構22的間距較小,愈接近樁體21中央的所述水平強化機構22的間距較大。Moreover, the spacing of the horizontal reinforcing mechanism 22 is proportional to the distance of the horizontal reinforcing mechanism 22 with respect to the first annular opening end plate 23 and the second annular opening end plate 24, that is, the closer to the The pitch of the horizontal reinforcing mechanism 22 of the first annular open end plate 23 or the second annular open end plate 24 is small, and the pitch of the horizontal reinforcing mechanism 22 closer to the center of the pile 21 is larger.

利用所述沿該樁體21的全長間隔設置,而且每兩相鄰的間距不大於該樁體21外徑的1.2倍的水平強化機構22,約可補強圖12中的綜合作用力F,以提升整體強度並穩定傳遞荷重。而將每一水平強化金屬件221的連接段223嵌置於該混凝土樁壁211內,能進一步提升所述水平強化金屬件221與該混凝土樁壁211的結合力。By using the horizontal reinforcing mechanism 22 disposed along the entire length of the pile body 21 and each two adjacent spacings not greater than 1.2 times the outer diameter of the pile body 21, the combined force F in FIG. 12 can be reinforced to Improve overall strength and stabilize load transfer. The connecting portion 223 of each horizontal reinforcing metal member 221 is embedded in the concrete pile wall 211, and the bonding force between the horizontal reinforcing metal member 221 and the concrete pile wall 211 can be further improved.

所述水平強化機構22的間距也可以是相同的,以便能在工廠生產中方便施行。在樁體21的全長度中,以樁體21兩端最為脆弱,同時也有接樁的需求。所以,在接近該樁體21兩端的所述水平強化機構22的間距較小,而在接近該樁體21中央處的所述水平強化機構22的間距較大的設計,不僅可以符合樁體21的力量行為達成強化的效果又能兼顧成本。The spacing of the horizontal reinforcing mechanisms 22 can also be the same so as to be easily implemented in factory production. Among the full length of the pile body 21, the ends of the pile body 21 are the most fragile, and there is also a demand for the pile. Therefore, the pitch of the horizontal reinforcing mechanism 22 near the both ends of the pile body 21 is small, and the design of the horizontal reinforcing mechanism 22 near the center of the pile body 21 is large, which can conform not only to the pile body 21 The power behavior achieves the effect of strengthening and can balance the cost.

實際應用上,所述水平強化機構22也可以如圖15所示具有兩兩交叉相疊而概呈十字型的水平強化金屬件221。利用增加水平強化金屬件221的數量,可以提升承受沿軸線L(顯示於圖13)方向之剪力的能力。In practical applications, the horizontal reinforcing mechanism 22 may also have a horizontally-strengthened metal member 221 that is cross-shaped and has a cross shape as shown in FIG. By increasing the number of horizontal reinforcing metal members 221, the ability to withstand shear forces in the direction of the axis L (shown in Figure 13) can be increased.

當該樁體21外徑加大,該樁體21截面的周長也會相對應的加大,必須增加所述水平加強金屬件221的數量,以便增加和該混凝土樁壁211的接觸點位置,以均勻力量的傳遞。當然,所述水平強化機構22也可以如圖16所示具有兩兩交叉相疊且靠近混凝土樁壁211而概呈井字型的水平強化金屬件221。以增加該混凝土樁壁211中間部位的空間,以便於灌漿管(圖中假想線所示)的進出操作。此 外,所述水平強化機構22也可以如圖17所示具有三隻交叉相疊且靠近混凝土樁壁211而概呈三角型的水平強化金屬件221。When the outer diameter of the pile body 21 is increased, the circumference of the section of the pile body 21 is correspondingly increased, and the number of the horizontal reinforcing metal members 221 must be increased to increase the contact point position with the concrete pile wall 211. , with the transmission of even power. Of course, the horizontal reinforcing mechanism 22 may also have a horizontally-strengthened metal member 221 which is formed in a well-shaped shape adjacent to the concrete pile wall 211 as shown in FIG. The space in the middle portion of the concrete pile wall 211 is increased to facilitate the entry and exit operation of the grouting pipe (shown as an imaginary line in the drawing). this Further, the horizontal reinforcing mechanism 22 may have three horizontal reinforcing metal members 221 which are triangularly stacked adjacent to the concrete pile wall 211 as shown in FIG.

而每一水平強化金屬件221的所述連接段223除了如圖14所示筆直錨固於該混凝土樁壁211內之外,也可以如圖18所示,其中一連接段223是直線錨固於該混凝土樁壁211內,另一連接段223則是相對該結構段222彎折而錨固於該混凝土樁壁211內,或是如圖19所示,每一水平強化金屬件221的兩連接段223是同方向彎折而錨固於該混凝土樁壁211內,或是如圖20所示,每一水平強化金屬件221的兩連接段223是不同方向彎折而錨固於該混凝土樁壁211內,甚是如圖21、22所示,每一水平強化金屬件221的兩連接段223的斷面積大於一體連設的該結構段222的斷面積以增加錨定強度。當然,在實際應用上,所述水平向強化金屬件221可以是竹節鋼筋或圓形鋼棒或方形鋼棒,而且所述水平向強化金屬件221的其中一連接段223可以是筆直或是彎折地錨固於該混凝土樁壁211內,另一連接段223則是斷面積較大之擴大頭的型態,依然具有增加錨固強度的效果。The connecting portion 223 of each horizontal reinforcing metal member 221 can be directly anchored in the concrete pile wall 211 as shown in FIG. 14 , as shown in FIG. 18 , wherein a connecting portion 223 is linearly anchored thereto. In the concrete pile wall 211, another connecting section 223 is bent and anchored in the concrete pile wall 211 with respect to the structural section 222, or as shown in FIG. 19, two connecting sections 223 of each horizontal reinforcing metal member 221 Is bent in the same direction and anchored in the concrete pile wall 211, or as shown in FIG. 20, the two connecting sections 223 of each horizontal reinforcing metal member 221 are bent in different directions and anchored in the concrete pile wall 211. As shown in Figs. 21 and 22, the sectional area of the two connecting sections 223 of each horizontal reinforcing metal member 221 is larger than the sectional area of the integrally connected structural section 222 to increase the anchoring strength. Of course, in practical applications, the horizontal reinforcing metal member 221 may be a bamboo reinforcing bar or a round steel bar or a square steel bar, and one of the connecting portions 223 of the horizontal reinforcing metal member 221 may be straight or curved. The folded ground is anchored in the concrete pile wall 211, and the other connecting section 223 is a type of enlarged head having a large sectional area, and still has the effect of increasing the anchoring strength.

參閱圖23,本新型混凝土樁之第二實施例大致是與該第一實施例相似,不相同的地方在於:該混凝土樁還包含一封設於該第二環狀開口端板24外的封板25,且所述水平強化機構22間的間距是相等的。由於本實施例大致是與該第一實施例相似,因此,除了可以達成與該第一實 施例相同的功效外,也提供另一種實施態樣供使用者選擇。Referring to Figure 23, the second embodiment of the present concrete pile is substantially similar to the first embodiment. The difference is that the concrete pile further includes a seal disposed outside the second annular open end plate 24. The plates 25 and the spacing between the horizontal reinforcing mechanisms 22 are equal. Since the embodiment is substantially similar to the first embodiment, in addition to being able to achieve the first In addition to the same efficacy of the embodiment, another embodiment is also provided for the user to select.

參閱圖24,本新型混凝土樁之第三實施例大致是與該第二實施例相似包含一樁體21、多數水平強化機構22,及一第一環狀開口端板23。不同的地方在於:混凝土樁還包含一連設於該樁體21遠離該第一環狀開口端板23之一端以封擋該通孔216的封板25。由於本實施例大致是與該第一實施例相似,因此,除了可以達成與該第一實施例相同的功效外,直接以封板25連設於該樁體21遠離該第一環狀開口端板23之一端,可以減少構件降低成本。Referring to Fig. 24, a third embodiment of the present concrete pile substantially comprises a pile body 21, a plurality of horizontal reinforcing mechanisms 22, and a first annular open end plate 23 similarly to the second embodiment.

The ring wall portion 212 cooperates with the stop portion 213 to define the ring portion 212. The blind hole 217, the axial steel bar 214 and the spiral steel wire 215 and the horizontal reinforcing mechanism 22 are within the entire length of the ring wall portion 212, and the connecting portion of each horizontal reinforcing metal member 221 223 is anchored to the ring wall portion 212. Since the present embodiment is substantially similar to the first embodiment, in addition to the same effects as the first embodiment, another embodiment is provided for the user to select.

參閱圖26,本新型混凝土樁之第五實施例,大 致是與該第四實施例相似,不相同的地方在於:該擋止部213的外徑大於該環壁部212的外徑,以創造出比該環壁部212更大的樁底截面積增加樁端承載力。Referring to Figure 26, the fifth embodiment of the novel concrete pile is large Therefore, similar to the fourth embodiment, the difference is that the outer diameter of the stopping portion 213 is larger than the outer diameter of the annular wall portion 212 to create a larger cross-sectional area of the pile bottom than the annular wall portion 212. Increase the bearing capacity of the pile end.

參閱圖27,本新型混凝土樁之第六實施例,大致是與該第四實施例相似,不相同的地方在於:該混凝土樁壁211具有一環壁部212,及一個一體連設於該環壁部212之一端且呈尖錐狀的擋止部213,該環壁部212與該擋止部213相配合界定出該盲孔217。Referring to Fig. 27, a sixth embodiment of the present concrete pile is substantially similar to the fourth embodiment. The difference is that the concrete pile wall 211 has a ring wall portion 212 and an integral connection to the ring wall. One end of the portion 212 has a tapered tapered stop portion 213 that cooperates with the stop portion 213 to define the blind hole 217.

由於本實施例大致是與該第四實施例相似,因此,除了可以達成與該第四實施例相同的功效外,尖錐狀的擋止部213,可以直接利用打樁機(圖未示)打擊入地下土層。Since the present embodiment is substantially similar to the fourth embodiment, in addition to the same effect as the fourth embodiment, the tip-shaped stopper portion 213 can be directly struck by a pile driver (not shown). Into the underground soil.

參閱圖28、29,本新型複合式混凝土樁之第一實施例包含一下樁單元3、一位於該下樁單元3上方的上樁單元4,及一軸向連接該上樁單元4與該下樁單元3的軸向強化單元5。Referring to Figures 28 and 29, a first embodiment of the composite concrete pile of the present invention comprises a lower pile unit 3, a pile unit 4 located above the pile unit 3, and an axial connection of the pile unit 4 and the lower portion. The axial reinforcement unit 5 of the pile unit 3.

由於本實施例中的該下樁單元3大致與本案圖23所示混凝土樁之第二實施例相同,而該上樁單元4大致與本案圖13所示混凝土樁之第一實施例相同,因此,該下樁單元3與該上樁單元4的結構在此不多加說明。Since the pile unit 3 in this embodiment is substantially the same as the second embodiment of the concrete pile shown in FIG. 23, the pile unit 4 is substantially the same as the first embodiment of the concrete pile shown in FIG. The structure of the lower pile unit 3 and the pile unit 4 will not be described here.

該軸向強化單元5包括一沿該軸線L完全貫穿所述樁體21的通孔216的軸向連結機構51,及一完全灌注於所述樁體21的通孔216內且包覆位於所述通孔216內的所述軸向連結機構51與所述水平強化機構22的填芯混凝 土52。該下樁單元3的封板25可以作為灌注該填芯混凝土52的模板,而該軸向連結機構51具有多數沿該混凝土樁壁211的周緣間隔設置的軸向連結鋼筋511。The axial reinforcing unit 5 includes an axial coupling mechanism 51 that completely penetrates the through hole 216 of the pile body 21 along the axis L, and a through hole 216 completely filled in the pile body 21 and covered by the cover. The axial connection mechanism 51 in the through hole 216 and the core reinforcement of the horizontal reinforcement mechanism 22 Earth 52. The sealing plate 25 of the lower pile unit 3 can serve as a template for injecting the cored concrete 52, and the axial coupling mechanism 51 has a plurality of axially-connecting reinforcing bars 511 spaced along the circumference of the concrete pile wall 211.

於本實施例中,所述軸向連結鋼筋511的一端是觸抵於該封板25,而另一端則是全部突出該上樁單元4樁頂的第一環狀開口端板23以連接一基礎承台200。實際應用上,所述軸向連結鋼筋511的也可以只是接近該封板25,而另一端則是部分凸出該上樁單元4的第一環狀開口端板23,依然可以達成相同的功效。In this embodiment, one end of the axially-connecting reinforcing bar 511 is in contact with the sealing plate 25, and the other end is a first annular open end plate 23 that protrudes from the top of the pile-up unit 4 to connect one. Foundation cap 200. In practical applications, the axially-connected reinforcing bar 511 may only be close to the sealing plate 25, and the other end is a first annular open end plate 23 partially protruding from the upper pile unit 4, and the same effect can still be achieved. .

該填芯混凝土52硬化後,和所述軸向連結鋼筋511及所述水平強化機構22的水平強化金屬件221結合成為穩定的鋼筋混凝土結構,並進一步與該上樁單元4及該下樁單元3結合為穩定的結構體,不但能同時藉由該上樁單元4的該樁體21,以及由所述軸向連結鋼筋511、該填芯混凝土52與所述水平強化金屬件221結合而成的鋼筋混凝土結構,而穩定地將該基礎承台200的荷重傳遞到該上樁單元4與該下樁單元3周邊和底部的土層,還可以提升所述相連接之該上樁單元4與該下樁單元3間的結合力與穩定性,進而提升整體的拉拔抵抗力、承載力、水平剪力與結構強度。於本實施例中該填芯混凝土52是使用普通型混凝土。實際應用上,也可以使用早強型混凝土,以便進一步縮減該填芯混凝土52的乾硬時間,由傳統的28天的乾硬時間,縮減到3至7天,可以有效的節省工期。After the core-filled concrete 52 is hardened, it is combined with the axially-bonded steel bars 511 and the horizontal reinforcing metal members 221 of the horizontal reinforcing mechanism 22 to form a stable reinforced concrete structure, and further with the pile unit 4 and the pile unit 3 is a stable structure, which can be combined not only by the pile body 21 of the pile unit 4 but also by the axially-connected steel bar 511, the core-filled concrete 52 and the horizontal reinforcing metal piece 221 Reinforced concrete structure, and stably transfer the load of the foundation cap 200 to the soil layer of the upper pile unit 4 and the periphery and bottom of the pile unit 3, and the pile unit 4 connected to the pile can be lifted The bonding force and stability between the pile units 3 further improve the overall drawing resistance, bearing capacity, horizontal shear force and structural strength. In the present embodiment, the core-filled concrete 52 is made of ordinary type concrete. In practical applications, early-strength concrete can also be used to further reduce the dry-hardening time of the core-filled concrete 52, which is reduced from the traditional 28-day dry-hard time to 3 to 7 days, which can effectively save the construction period.

而且當該上樁單元4的第二環狀開口端板24, 與該下樁單元3的第一環狀開口端板23的接合處C發生鏽蝕時,由所述軸向連結鋼筋511、填芯混凝土52與所述水平強化金屬件221結合而成的鋼筋混凝土結構仍然保持完整,因此,該上樁單元4與該下樁單元3的螺旋鋼線215仍可提供由所述軸向連結鋼筋511、填芯混凝土52與所述水平強化金屬件221結合而成的鋼筋混凝土結構充足的鋼線功能,以繼續傳遞基礎承台200的荷重,不用擔心結構弱化與可靠度降低等問題。此外,利用填芯混凝土52包覆位於所述通孔216內的所述軸向連結鋼筋511與所述水平強化金屬件221,所述軸向連結鋼筋511與所述水平強化金屬件221不但不易發生鏽蝕,更能充份確保該上樁單元4與該下樁單元3接合處C的強度。And when the second annular open end plate 24 of the upper pile unit 4, When the joint C of the first annular open end plate 23 of the pile unit 3 is rusted, the reinforced concrete is formed by combining the axially-connected steel bar 511, the cored concrete 52 and the horizontal reinforcing metal member 221 The structure remains intact. Therefore, the upper pile unit 4 and the spiral steel wire 215 of the lower pile unit 3 can still be provided by the axially-connected steel bar 511, the cored concrete 52 and the horizontal reinforcing metal member 221 The reinforced concrete structure has sufficient steel wire function to continue to transfer the load of the foundation cap 200 without worrying about structural weakening and reduced reliability. In addition, the axially-bonded reinforcing bar 511 located in the through hole 216 and the horizontal reinforcing metal member 221 are covered by the core-filled concrete 52, and the axially-connecting reinforcing bar 511 and the horizontal reinforcing metal piece 221 are not only difficult. The rust is rusted, and the strength of the joint C between the pile unit 4 and the pile unit 3 is more fully ensured.

於本實施例中,該上樁單元4與該下樁單元3的樁體21尺寸都是外徑60厘米、內徑40厘米、長度12米;每兩相鄰之水平強化機構22的縱軸向間距是30厘米,而所述水平強化機構22的所述水平強化金屬件221是直徑16毫米、降伏強度為2800kg/cm2 (約為274N/mm2 或約39853psi)的竹節鋼筋;而該軸向強化單元5包括12支軸向連結鋼筋511,每一軸向連結鋼筋511是直徑22毫米、降伏強度為4200kg/cm2 (約為412N/mm2 或約59779psi)的竹節鋼筋,該填芯混凝土52的抗壓強度是280kg/cm2 (約為27N/mm2 或約3985psi)。In the present embodiment, the pile unit 4 of the pile unit 4 and the pile unit 3 have an outer diameter of 60 cm, an inner diameter of 40 cm, and a length of 12 m; the longitudinal axis of each two adjacent horizontal reinforcing mechanisms 22 The pitch is 30 cm, and the horizontal reinforcing metal member 221 of the horizontal reinforcing mechanism 22 is a bamboo reinforcing bar having a diameter of 16 mm and a relief strength of 2800 kg/cm 2 (about 274 N/mm 2 or about 39853 psi); The axial reinforcing unit 5 includes 12 axially-connecting reinforcing bars 511, and each of the axially-connecting reinforcing bars 511 is a bamboo reinforcing bar having a diameter of 22 mm and a relief strength of 4200 kg/cm 2 (about 412 N/mm 2 or about 59779 psi). The compressive strength of the core concrete 52 is 280 kg/cm 2 (about 27 N/mm 2 or about 3985 psi).

當該上樁單元4的第二環狀開口端板24,與該下樁單元3的第一環狀開口端板23的接合處C發生鏽蝕 時,該軸向強化單元5仍能提供:拉力=軸向連結鋼筋數*鋼筋斷面積*鋼筋強度=12支*(π/4*2.22)*4200kg/cm2 =191 ton的拉力;在承受壓力時,也可以有191 ton的抗壓力,或由該填芯混凝土52承受=混凝土面積*混凝土強度=(π/4*402)*280kg/cm2 =351 ton的壓力。因此,本實施例確實足以繼續傳遞基礎承台200的荷重,不用擔心接合處C因鏽蝕所造成之結構弱化與可靠度降低等問題。When the second annular open end plate 24 of the pile unit 4 is rusted with the joint C of the first annular open end plate 23 of the pile unit 3, the axial reinforcing unit 5 can still provide: pulling force = axial joint reinforcement number * steel joint area * reinforcement strength = 12 * (π / 4 * 2.22) * 4200kg / cm 2 = 191 ton of tensile force; when subjected to pressure, there may be 191 ton of anti-stress, or The cored concrete 52 is subjected to = concrete area * concrete strength = (π / 4 * 402) * 280 kg / cm 2 = 351 ton of pressure. Therefore, the present embodiment is indeed sufficient to continue to transfer the load of the foundation cap 200 without worrying about problems such as structural weakening and reduced reliability due to rust at the joint C.

參閱圖30、31,本新型複合式混凝土樁之第二實施例大致是與該複合式混凝土樁的第一實施例相似,不相同的地方在於:該複合式混凝土樁的軸向強化單元5包括4個軸向連結機構51,每一軸向連結機構51具有3支軸向連結鋼筋511,以及多數沿該軸線L間隔分佈於所述軸向連結鋼筋511上,以固定所述軸向連結鋼筋511的繫結鋼筋512。利用所述繫結鋼筋512定位所述軸向連結鋼筋511,能確保所述軸向連結鋼筋511的位置與間距,便於將所述軸向連結鋼筋511穿置所述通孔216。Referring to Figures 30 and 31, the second embodiment of the composite concrete pile of the present invention is substantially similar to the first embodiment of the composite concrete pile, and the difference is that the axial reinforcement unit 5 of the composite concrete pile includes Four axial coupling mechanisms 51 each having three axially-connecting reinforcing bars 511 and a plurality of axially-connecting reinforcing bars 511 spaced along the axis L to fix the axially-connected reinforcing bars The 511 is tied to the reinforcing bar 512. Positioning the axially-connecting reinforcing bars 511 by the reinforcing bars 512 can ensure the position and spacing of the axially-connecting reinforcing bars 511, and facilitate the insertion of the axially-connecting reinforcing bars 511 through the through-holes 216.

由於該複合式混凝土樁的通孔216的深度相當深,要逐支將所述軸向連結鋼筋511插入所述通孔216中,又要保持固定的間距是相當費時又不容易的作業。利用所述繫結鋼筋512,將所述軸向連結鋼筋511組合成一個軸向連結機構51,一次插入施工,可集中多數軸向連結機構51一併施工,除了可保持所述軸向連結鋼筋511的適當間距與提升品質外,更能節省施工時間。Since the depth of the through hole 216 of the composite concrete pile is relatively deep, it is quite time-consuming and not easy to maintain the fixed spacing by inserting the axially-connected reinforcing bar 511 into the through hole 216. The axially-connected reinforcing bars 511 are combined into one axial connecting mechanism 51 by the reinforced reinforcing bars 512, and the primary axial connecting mechanism 51 can be assembled in one insertion, in addition to maintaining the axially-connected reinforcing bars. In addition to the proper spacing and quality of the 511, construction time can be saved.

參閱圖32,本新型複合式混凝土樁之第三實施 例大致是與該複合式混凝土樁的第二實施例相似,不相同的地方在於:該複合式混凝土樁包含兩相互上下疊置接合的上樁單元4。由於本實施例大致是與該第二實施例相似,因此,除了可以達成與該第二實施例相同的功效外,還能增加複合式混凝土樁的總長以深入更深的土層中。當複合式混凝土樁的總長度須要更長時,利用本實施例的方式類推,結合更多的該上樁單元4即可達到目的,例如連接二節以上的該上樁單元4。Referring to Figure 32, the third implementation of the novel composite concrete pile The example is roughly similar to the second embodiment of the composite concrete pile, and the difference is that the composite concrete pile comprises two upper pile units 4 which are stacked one above another. Since the present embodiment is substantially similar to the second embodiment, in addition to the same effect as the second embodiment, the total length of the composite concrete pile can be increased to penetrate deeper into the soil layer. When the total length of the composite concrete pile needs to be longer, the purpose of the embodiment can be used in combination with more of the pile unit 4, for example, connecting the pile unit 4 of two or more sections.

參閱圖33,本新型複合式混凝土樁之第四實施例大致是與該複合式混凝土樁的第二實施例相似,不相同的地方在於:該下樁單元3的樁體21的外徑,大於所述上樁單元4的樁體21的外徑。利用外徑稍大的該下樁單元3,擴複合式混凝土樁的部面積,以增加複合式混凝土樁的承載力。Referring to Figure 33, the fourth embodiment of the composite concrete pile of the present invention is substantially similar to the second embodiment of the composite concrete pile. The difference is that the outer diameter of the pile 21 of the lower pile unit 3 is larger than The outer diameter of the pile body 21 of the pile unit 4. The portion of the composite concrete pile is expanded by the lower pile unit 3 having a slightly larger outer diameter to increase the bearing capacity of the composite concrete pile.

在實際應用時,該下樁單元3的樁體21的外徑一般可以是該上樁單元4的樁體21的外徑再擴大10至40厘米,即每一側約擴大5至20厘米最為合適。於本實施例中,該上樁單元4的樁體21的外徑是1.0米,該下樁單元3的樁體21的外徑是1.2米,比該上樁單元4的樁體21的外徑每一側各擴大了10厘米,外徑擴大比率為1.2/1.0=120%。該上樁單元4的樁體21的外緣面積=π/4*1.02=0.7854m2 ,該下樁單元3的樁體21的外緣面積=π/4*1.22=1.1310m2 ,面積擴大比率約為=1.1310/0.7854=144%,意思是樁端承載力增加了約44%。In practical applications, the outer diameter of the pile body 21 of the pile unit 3 may generally be an outer diameter of the pile body 21 of the pile unit 4 further enlarged by 10 to 40 cm, that is, each side is enlarged by about 5 to 20 cm. Suitable. In the present embodiment, the outer diameter of the pile 21 of the pile unit 4 is 1.0 m, and the outer diameter of the pile 21 of the pile unit 3 is 1.2 m, which is larger than the pile 21 of the pile unit 4. Each side of the diameter is enlarged by 10 cm, and the outer diameter expansion ratio is 1.2/1.0 = 120%. The outer edge area of the pile 21 of the pile unit 4 is π/4*1.02=0.7854 m 2 , and the outer edge area of the pile 21 of the pile unit 3 is π/4*1.22=1.1310 m 2 , and the area is enlarged. The ratio is approximately =1.1310/0.7854 = 144%, which means that the bearing capacity of the pile end is increased by about 44%.

參閱圖34,本新型複合式混凝土樁之第五實施例大致是與該複合式混凝土樁的第二實施例相似,不相同的地方在於:該下樁單元3的樁體21的混凝土樁壁211具有一與該上樁單元4的樁體21外徑相同的上段218,及一外徑大於該上段218的下段219。由於樁端承載力與樁的底端面積相關連,本實施例不只可以達成與該第四實施例相同的功效,還可節省成本。Referring to Fig. 34, the fifth embodiment of the composite concrete pile of the present invention is substantially similar to the second embodiment of the composite concrete pile, and the difference is that the concrete pile wall 211 of the pile body 21 of the pile unit 3 is There is an upper section 218 having the same outer diameter as the pile body 21 of the pile unit 4, and a lower section 219 having an outer diameter larger than the upper section 218. Since the bearing capacity of the pile end is related to the bottom end area of the pile, this embodiment can achieve not only the same effect as the fourth embodiment but also cost saving.

參閱圖35,本新型複合式混凝土樁之第六實施例大致是與該複合式混凝土樁的第一實施例相似,不相同的地方在於:該下樁單元3是本案圖24所示混凝土樁之第三實施例。由於本實施例大致是與該第一實施例相似,因此,除了可以達成與該第一實施例相同的功效外,直接以封板25封擋該通孔216,可以節省材料以降低成本。Referring to FIG. 35, the sixth embodiment of the composite concrete pile of the present invention is substantially similar to the first embodiment of the composite concrete pile.

Since the present embodiment is substantially similar to the first embodiment, in addition to the same effect as the first embodiment, the through hole 216 can be directly blocked by the sealing plate 25, which can save material and reduce cost.

參閱圖36,本新型複合式混凝土樁之第七實施例大致是與該複合式混凝土樁的第六實施例相似,不相同的地方在於:該下樁單元3是本案圖25所示混凝土樁之第四實施例,以該盲孔217容置填芯混凝土52,提供另一種態樣供使用者選擇。Referring to FIG. 36, the seventh embodiment of the composite concrete pile of the present invention is substantially similar to the sixth embodiment of the composite concrete pile. The difference is that the pile unit 3 is the concrete pile shown in FIG. 25 of the present case. In the fourth embodiment, the cored concrete 52 is accommodated by the blind hole 217 to provide another aspect for the user to select.

參閱圖37,本新型複合式混凝土樁之第八實施例大致是與該複合式混凝土樁的第六實施例相似,不相同的地方在於:該下樁單元3是本案圖27所示混凝土樁之第五實施例,以該盲孔217容置填芯混凝土52,配合呈尖錐狀的擋止部213可以利用打樁機(圖未示)直接打擊入地下土層,或利用壓樁機(圖未示)壓入地下土層,提供另一種態 樣供使用者選擇。Referring to Fig. 37, the eighth embodiment of the composite concrete pile of the present invention is substantially similar to the sixth embodiment of the composite concrete pile. The difference is that the pile unit 3 is the concrete pile shown in Fig. 27 of the present case. In the fifth embodiment, the blind hole 217 is used to accommodate the core-filled concrete 52, and the tip-shaped stopper portion 213 can be directly struck into the underground soil layer by using a pile driver (not shown), or by using a pile driver (Fig. Not shown) pressed into the subterranean soil to provide another state Sample for the user to choose.

參閱圖38,本新型複合式混凝土樁之第九實施例,大致是與該複合式混凝土樁的第六實施例相似,不相同的地方在於:該下樁單元3的封板25是封擋於該通孔216中。所述水平強化機構22設置在該封板25的上方,而所述軸向連結鋼筋511及該填芯混凝土52也位於在該封板25之上方。Referring to FIG. 38, a ninth embodiment of the composite concrete pile of the present invention is substantially similar to the sixth embodiment of the composite concrete pile. The difference is that the sealing plate 25 of the lower pile unit 3 is sealed. The through hole 216 is in the middle. The horizontal reinforcing mechanism 22 is disposed above the sealing plate 25, and the axially-connecting reinforcing bars 511 and the core-filled concrete 52 are also located above the sealing plate 25.

一般而言,該下樁單元3的樁體21的混凝土樁壁211主要是由高強度混凝土構成,一般的強度都高達500kg/cm2 (約為49N/mm2 或約7117psi)至800kg/cm2 (約為78N/mm2 或約11387psi),而使用的填芯混凝土52的強度一般都只在210kg/cm2 (約為20N/mm2 或約2989psi)至350kg/cm2 (約為34N/mm2 或約4982psi)之間,相形之下,該下樁單元3的樁體21的混凝土樁壁211的強度高出填芯混凝土52甚多。In general, the concrete pile wall 211 of the pile body 21 of the pile unit 3 is mainly composed of high-strength concrete, and generally has a strength of up to 500 kg/cm 2 (about 49 N/mm 2 or about 7117 psi) to 800 kg/cm. 2 (about 78 N/mm 2 or about 11387 psi), and the strength of the cored concrete 52 used is generally only 210 kg/cm 2 (about 20 N/mm 2 or about 2989 psi) to 350 kg/cm 2 (about 34 N). Between /mm 2 or about 4982 psi), the concrete pile wall 211 of the pile body 21 of the pile unit 3 has a higher strength than the core-filled concrete 52.

而該下樁單元3是位於整體複合式混凝土樁的最下端,當來自上方基礎承台200的重量,經過該上樁單元4而傳遞至該下樁單元3時,只要該封板25與該接合處C的距離能滿足所述軸向連結鋼筋511的錨定握持所需長度,即可將力量傳遞到該下樁單元3的混凝土樁壁211,再傳遞給周圍及底部的土壤,而達到本新型的目的,並不需要該封板25以下的填芯混凝土52來補助傳遞。The lower pile unit 3 is located at the lowermost end of the integral composite concrete pile, and when the weight from the upper foundation platform 200 is transmitted to the lower pile unit 3 through the pile unit 4, as long as the sealing plate 25 and the The distance of the joint C can satisfy the required length of the anchoring holding of the axially-connected reinforcing bar 511, that is, the force can be transmitted to the concrete pile wall 211 of the pile unit 3, and then transmitted to the surrounding and bottom soil. To achieve the purpose of the present invention, the cored concrete 52 below the sealing plate 25 is not required to assist in the transfer.

而且該軸向強化單元5已跨越接合處C,因此,本實施例確實足以繼續傳遞基礎承台200的荷重,不用擔 心因接合處C鏽蝕所造成之結構弱化與可靠度降低等問題。在實際應用上,該封板25為鋼板,且該封板25與該接合處C的距離,一般不小於2米。Moreover, the axial reinforcing unit 5 has crossed the joint C, and therefore, the embodiment is indeed sufficient to continue to transfer the load of the foundation cap 200 without The problem of weakening the structure and reducing the reliability of the heart due to the corrosion of the joint C. In practical applications, the sealing plate 25 is a steel plate, and the distance between the sealing plate 25 and the joint C is generally not less than 2 meters.

參閱圖39、40,說明本新型複合式混凝土樁的工地施作方法,是以包含一上樁單元4、一下樁單元3與一軸向強化單元5的複合式混凝土樁作說明。Referring to Figures 39 and 40, the construction method of the composite concrete pile of the present invention will be described as a composite concrete pile comprising a pile unit 4, a pile unit 3 and an axial reinforcement unit 5.

該上樁單元4與下樁單元3的樁體21尺寸為外徑100厘米、內徑72厘米、長度16米。而該上樁單元4與下樁單元3接近兩端的水平強化機構22的間距是30厘米,中間部份的水平強化機構22的間距是60厘米。兩端間距較密的設計是用來補強接合處C、與基礎承台200(顯示於圖37)連結處,以及底部與土壤間的強度。The pile 21 of the upper pile unit 4 and the lower pile unit 3 has an outer diameter of 100 cm, an inner diameter of 72 cm, and a length of 16 m. The distance between the horizontal reinforcing mechanism 22 of the upper pile unit 4 and the lower pile unit 3 near the two ends is 30 cm, and the spacing of the horizontal reinforcing mechanism 22 at the intermediate portion is 60 cm. The densely spaced design at both ends is used to reinforce the joint C, the joint with the foundation cap 200 (shown in Figure 37), and the strength between the bottom and the soil.

而所述水平強化金屬件221是如圖40所示概呈井字型,且直徑為16毫米、降伏強度為2800kg/cm2 (約為274N/mm2 或約39853psi)的竹節鋼筋,兩相水平間隔而不重疊之水平強化金屬件221的間距是50厘米,進而於中央處形成一50厘米X50厘米的矩形穿置空間;該軸向強化單元5有28支軸向連結鋼筋511,每一軸向連結鋼筋511是直徑35亳米、降伏強度為4200kg/cm2 (約為412N/mm2 或約59779psi)的竹節鋼筋,而該填芯混凝土52的抗壓強度為280kg/cm2 (約為27N/mm2 或約3985psi)。The horizontal reinforcing metal member 221 is a bamboo bar having a diameter of 16 mm and a relief strength of 2800 kg/cm 2 (about 274 N/mm 2 or about 39853 psi) as shown in FIG. The horizontally reinforced metal members 221 having a horizontal interval without overlapping are 50 cm apart, and a rectangular wearing space of 50 cm X 50 cm is formed at the center; the axial reinforcing unit 5 has 28 axially-connected reinforcing bars 511, each The axially-connected reinforcing bar 511 is a bamboo bar having a diameter of 35 mm and a relief strength of 4200 kg/cm 2 (about 412 N/mm 2 or about 59779 psi), and the core-filled concrete 52 has a compressive strength of 280 kg/cm 2 (about It is 27 N/mm 2 or about 3985 psi).

先以機具61在鑽掘出深度15米的臨時工作孔62;接下來,在該臨時工作孔62中設置一鋼套管63,用以在長時間的施工期間,保護該臨時工作孔62的孔壁土壤, 不致崩塌。然後,將該下樁單元3吊置在該臨時工作孔62中,突出地面約1米;之後,再將該上樁單元4吊置在該下樁單元3的上方,以銲接方式銲合將該上樁單元4的第二環狀開口端板24與該下樁單元3的第一環狀開口端板23。First, a temporary working hole 62 having a depth of 15 meters is drilled with the implement 61; next, a steel sleeve 63 is disposed in the temporary working hole 62 for protecting the temporary working hole 62 during long-term construction. Hole wall soil, Do not collapse. Then, the lower pile unit 3 is suspended in the temporary working hole 62, and protrudes from the ground by about 1 meter; after that, the upper pile unit 4 is suspended above the lower pile unit 3, and welded by welding. The second annular open end plate 24 of the upper pile unit 4 and the first annular open end plate 23 of the lower pile unit 3.

再將所述軸向連結鋼筋511分次吊置入該上樁單元4與該下樁單元3的通孔216中,直至觸抵或接近該下樁單元3封板25,最後以特密管混凝土灌漿施工方式,將口徑6英吋(約為15厘米)的特密管64伸入該穿置空間中,以將該填芯混凝土52灌注入該上樁單元4與該下樁單元3的通孔216中,在灌注同時也逐步拔出該特密管64。Then, the axially-connected reinforcing bar 511 is successively suspended into the through-hole 216 of the upper pile unit 4 and the lower pile unit 3 until it touches or approaches the lower pile unit 3 sealing plate 25, and finally is a special tube. In the concrete grouting construction method, a special pipe 64 having a diameter of 6 inches (about 15 cm) is inserted into the wearing space to inject the core-filled concrete 52 into the pile unit 4 and the pile unit 3. In the through hole 216, the dense tube 64 is also gradually extracted while being poured.

參閱圖41,並一併回顧圖39、40,進一步以機具61在正確的位置鑽掘出孔徑為1.4米、深度為31.8米的樁孔65,然後,在樁孔65內部填滿水泥漿66以穩定該樁孔65的孔壁土壤不致崩塌,同時也作為該上樁單元4與該下樁單元3與地下土壤間的結合加強介質。之後將填芯混凝土52尚未乾硬的該混凝土樁吊置入該樁孔65中,而達到沈樁的目的。Referring to Figure 41, and referring back to Figures 39 and 40, the pile hole 65 having a diameter of 1.4 m and a depth of 31.8 m is further drilled in the correct position by the implement 61, and then the grout 66 is filled inside the pile hole 65. In order to stabilize the hole wall of the pile hole 65, the soil does not collapse, and also serves as a bonding reinforcing medium between the pile unit 4 and the pile unit 3 and the underground soil. Then, the concrete pile which has not been hardened by the core-filled concrete 52 is suspended into the pile hole 65 to achieve the purpose of sinking the pile.

由於該填芯混凝土52的黏稠度大於該水泥漿66,即使該樁孔65中的水泥漿66溢滿,也不會與該填芯混凝土52衝突或混合而影響質量。待該樁孔65中的水泥漿66與該填芯混凝土52乾硬後就完成混凝土樁的施作作業。Since the consistency of the core-filled concrete 52 is greater than that of the cement slurry 66, even if the cement slurry 66 in the pile hole 65 is full, it will not collide or mix with the core-filled concrete 52 to affect the quality. After the cement slurry 66 in the pile hole 65 and the core-filled concrete 52 are dry and hard, the concrete pile is applied.

當以上施作方法製成之複合式混凝土樁的接合 處C鏽蝕後,仍能提供:抗拉力=軸向連結鋼筋數*鋼筋斷面積*鋼筋強度=28支*(π/4*3.52)*4200kg/cm2 =約1131 ton,以及更高的抗壓力。When the joint C of the composite concrete pile made by the above application method is corroded, it can still provide: tensile strength = number of axially connected steel bars * steel bar broken area * steel bar strength = 28 pieces * (π / 4 * 3.52) *4200kg/cm 2 = about 1131 ton, and higher resistance to pressure.

而且由於該上樁單元4與該下樁單元3是在工廠中預製生產,不僅生產速度很快而且質量穩定,之後,在工地,以機具61進行鑽孔的速度相當快。因此,本新型複合式混凝土樁的施作方法的工期可以大幅縮短至傳統現場灌注樁的1/2以下,而且質量遠優於現場灌注混凝土樁。可以說是兼具預製樁和場鑄樁的優點,並改善現場灌注混凝土樁質量不穩定、施工工期長且成本高的缺點。當複合式混凝土樁的長度較長時,例如樁長為70米,可以在樁孔65中加設如圖39所示的鋼套管63(例如全長度或半長方式)以保護樁孔65的孔壁土壤不崩塌,以便利施工;或者土層的岩土條件(或稱地質條件)較嚴苛時,例如遭遇礫石土層或破碎岩層等,該機具61也可以使用抓斗機械取土或設置鑽頭鑽齒以破堅鏟土,這些都是目前普遍使用在土木工程上的樁孔鑽掘方式。Moreover, since the pile unit 4 and the pile unit 3 are prefabricated in the factory, not only the production speed is fast but also the quality is stable, and then, at the construction site, the drilling speed with the machine 61 is quite fast. Therefore, the construction period of the new composite concrete pile can be shortened to less than 1/2 of the traditional on-site pile, and the quality is much better than the on-site concrete pile. It can be said that it has the advantages of both prefabricated piles and field cast piles, and it has the disadvantages of unstable quality, long construction period and high cost of on-site concrete piles. When the length of the composite concrete pile is long, for example, the pile length is 70 meters, a steel sleeve 63 (for example, a full length or a half length manner) as shown in FIG. 39 may be added to the pile hole 65 to protect the pile hole 65. The soil of the hole wall does not collapse to facilitate construction; or when the geotechnical conditions (or geological conditions) of the soil layer are severe, such as encountering gravel soil or broken rock layers, the machine 61 can also use the grab machinery to take soil. Or set the drill bit to break the soil, these are the pile hole drilling methods currently used in civil engineering.

參閱圖42,本新型複合式混凝土樁的另一種工地施作方法,大致是與該前述施作方法相似,不相同的地方在於:該填芯混凝土52並非一次灌滿,而是在接近該上樁單元4的樁頂的第一環狀開口端板23處留下一段長度未灌注;而且所述軸向連結鋼筋511未突出該上樁單元4的樁頂的第一環狀開口端板23。等到將該複合式混凝土樁吊置入該樁孔65後,再以鋼筋續接器(圖未式)延長所述軸向 連結鋼筋511以突出在該上樁單元4的第一環狀開口端板23,未灌注填芯混泥土的部分,則是在灌注該基礎承台200時一併灌注。Referring to FIG. 42, another construction method of the composite concrete pile of the present invention is substantially similar to the foregoing application method, and the difference is that the core-filled concrete 52 is not filled once, but is close to the above. The first annular open end plate 23 of the pile top of the pile unit 4 leaves a length of unfilled; and the axially-connected steel bar 511 does not protrude from the first annular open end plate 23 of the pile top of the pile unit 4. . After the composite concrete pile is suspended into the pile hole 65, the axial direction is extended by a steel splicer (not shown). The reinforcing bars 511 are joined to protrude from the first annular open end plate 23 of the upper pile unit 4, and the portion of the unfilled core concrete is poured while being poured into the base platform 200.

所述軸向連結鋼筋511在樁頂處的延長,除了以鋼筋續接器(圖未式)延長的方式外,仍可以用土木施工現場中普遍使用的瓦斯鎔接的方式予以延長所述軸向連結鋼筋511;或者使用鋼筋搭接的方式,這些都是一般工程上使用來延長鋼筋長度的施工方法,也可以達到所述軸向連結鋼筋511的延長的目的。由於鋼筋的工廠生產長度有限制,出廠長度一般都在14米以下,上述的鋼筋延長方式也可以運用到所述軸向連結鋼筋511在樁身中的延長。The extension of the axially-connected reinforcing bar 511 at the top of the pile, in addition to the extension of the reinforcing bar splicer (not shown), can be extended by the gas splicing method commonly used in civil construction sites. These are the construction methods used in general engineering to extend the length of the steel bars, or the extension of the axially-connected steel bars 511. Since the factory production length of the steel bar is limited, the factory length is generally less than 14 meters, and the above-mentioned steel bar extension mode can also be applied to the extension of the axially-connected steel bar 511 in the pile body.

由於本施作方法大致是於前述施作方法相同,因此,除了可以達成與前述施作方法相同的功效外,也提供另一種施作方法供使用者選擇。Since the present application method is substantially the same as the above-described application method, in addition to the same effect as the above-described application method, another application method can be provided for the user to select.

參閱圖43、44,說明本新型複合式混凝土樁的另一種工地施作方法,大抵和前述的二種工地施作方法相同,不相同的地方在於:在臨時工作孔62的工作階段,只是銲接結合該上樁單元3及該下樁單元4,但並不將軸向連結鋼筋511插入,也不將該填芯混凝土52灌入該上樁單元3及該下樁單元4。Referring to Figures 43 and 44, another construction method of the composite concrete pile of the present invention is described, which is generally the same as the two construction methods described above, and the difference is that in the working stage of the temporary working hole 62, only welding The pile unit 3 and the pile unit 4 are combined, but the axially-connected steel bars 511 are not inserted, and the core-filled concrete 52 is not poured into the pile unit 3 and the pile unit 4.

接著將相互結合的該上樁單元3及該下樁單元4置入內部填滿水泥漿66的樁孔65,再將所述軸向連結鋼筋511插入該上樁單元3及該下樁單元4內,然後以該特密管64將該填芯混凝土52灌注在該上樁單元3及該下樁 單元4內,在灌注同時也逐步拔出該特密管64。待該樁孔65中的該水泥漿66與該填芯混凝土52乾硬後就完成該複合式混凝土樁的施作作業。Then, the upper pile unit 3 and the lower pile unit 4 which are combined with each other are placed into the pile hole 65 which is filled with the cement slurry 66, and the axially-connected steel bar 511 is inserted into the pile unit 3 and the pile unit 4. Inner, then the cored concrete 52 is poured into the pile unit 3 and the lower pile by the special pipe 64 In unit 4, the dense tube 64 is also gradually withdrawn during the filling. After the cement slurry 66 in the pile hole 65 and the core-filled concrete 52 are dry and hard, the operation of the composite concrete pile is completed.

不在臨時工作孔62進行大量的軸向連結鋼筋511的置入工作和填芯混凝土52的灌注工作。除了可避免在高處進行軸向連結鋼筋511置入工作和填芯混凝土52的灌注工作,降低自臨時工作孔62中吊起樁體的重量,減少工作人員的危險性外,也更能確保填芯混凝土52灌注的質量要求。The insertion work of a large number of axially-connected reinforcing bars 511 and the pouring operation of the core-filled concrete 52 are not performed in the temporary working holes 62. In addition to avoiding the axial joining of the reinforcing bars 511 and the filling work of the cored concrete 52 at a high place, the weight of the piles lifted from the temporary working holes 62 is reduced, and the danger of the worker is reduced, and the safety is also ensured. Quality requirements for cored concrete 52 infusion.

綜上所述,本新型混凝土樁利用所述沿該樁體21的全長間隔設置,而且每兩相鄰的間距不大於該樁體外徑的1.2倍的水平強化機構22,以提升整體強度並穩定傳遞荷重。再配合該軸向強化單元5,本新型複合式混凝土樁還能提升上下結合的該下樁單元3與該上樁單元4間的結合強度,故確實能達成本新型之目的。In summary, the new concrete pile is provided with the horizontal reinforcing mechanism 22 which is spaced apart along the entire length of the pile body 21 and each of which is not more than 1.2 times the outer diameter of the pile body to improve the overall strength and stability. Pass the load. Further, in combination with the axial reinforcing unit 5, the composite concrete pile of the present invention can also improve the bonding strength between the lower pile unit 3 and the upper pile unit 4 which are combined with each other, so that the object of the present invention can be achieved.

惟以上所述者,僅為本新型之較佳實施例而已,當不能以此限定本新型實施之範圍,即大凡依本新型申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾,皆仍屬本新型專利涵蓋之範圍內。However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
