201247971 六、發明說明： 【發明所屬之技術領域】 本發明是有關於一種建築用基樁及其施工方法，特別 是指一種可以有效降低成本與提高橫向握裹力之建築用基 樁及其施工方法。 【先前技術】 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’往往需應用打入地面的基樁以將上層之建築 物的載重傳遞至土壤承載層或較堅硬的地盤，以增加建築 物結構的安全性與穩定性。 再者’近年％保意識尚丨張’因此基播的施工還需要考 慮施工時之噪音、震動與所產生之空氣污染對週遭環境的 影響’故近年來植入式基樁愈來愈受到重視。 參閱圖1，現有植入式基樁1包括一具有一頂緣"I的 中空狀管體11。 參閱圖2,現有植入式基樁1的施工方法，是先在地面 上鑽掘出一植入孔21 ;接著將水泥漿1〇0注入該植入孔21 中；然後再將植入式基樁丨的管體U植入該植入孔21中， 使植入孔21内的水泥漿ι〇〇從管體丨丨底部進入並充滿於管 體11内，此時會有部份水泥漿100自該管體U與植入孔 21之間的間隙溢出’而與周邊土壤混雜後再經該頂緣u i 回流入該管體11中’而會在該管體u内鄰近該頂緣U1之 區域（亦稱為樁頭）凝固成混合有土壤的劣質混凝土 1〇〇，；爾 後將該植入式基樁1靜置14天以待水泥漿100凝固；之後 201247971 開挖該植入式基樁丨頂部外周緣的周邊土壤，使該植入式 基樁1的樁頭突伸於外，然後再自該管體u的頂緣U1内 部向下挖掘2公尺左右，以將前述位在該管體u内鄰近該 頂緣111之區域（即前述之樁頭）内的劣質混凝土 1〇〇,去除； ㈣將-鋼筋23穿置該鋼筋籠22並將該鋼筋籠22置二該 管體11中，而使該鋼筋23兩端跨抵於該管體u之頂緣 111上，使该鋼筋籠22是以懸吊方式吊掛於該鋼筋23上（ 如圖3之局部放大圖所示）；最後再注入混凝土 ι〇〇,，於管體 11内以包覆結合該基樁1與該鋼筋籠22(如圖4之局部放大 圖所示）’如此即完成植入式基樁1的施工。 現有的植入式基樁！及其施工方法，雖然能兼具低噪 9、低震動及低空氣污染等優點，但仍有下列缺點亟待改 善： 1.費工費時且成本高： 由於在將該管體11植入該植入孔21時，會有部份 水泥漿100自該管體Η與植入孔21之間的間隙向上溢 出回流，而與植入孔21周邊的土壤混雜後再經該管體 11之頂緣111回流入該管體u中，凝固成混合有土壤 的劣質混凝土 100,，因此現有植入式基樁i在開挖其頂 部外周緣的周邊土壌使樁頭露出之後，還需再去除樁頭 t之管體11内的劣質混凝土 100，，造成現有植入式基 樁1施工時所花費的時間成本與人力成本較高。 2·鋼筋籠22的錫定效果不佳： 由於該鋼筋籠22僅以該鋼筋23吊掛於該管體u 4 201247971 中’所以該鋼筋23僅靠其中央部位支撐該鋼筋籠22之 重量，但是上述方式無法穩固且確實地錨定。 3.管體11之橫向握裹力亦不足： 植入於該植入孔21中之基樁丨由於僅以該管體u 的内、外表面分別與水泥漿丨〇〇相互接觸，内、外表面 彼此之間並未連通而缺乏橫向之握裹力，因此於水泥漿 100凝固之後所能產生對於該管體丨丨的橫向握裹力較低 ，當該植入式基樁1的上層結構受到風力或地震力等橫 向或軸向作用力時，將容易造成該鋼筋籠22產生側向 位移甚至是鬆脫等現象，特別是對於該基樁丨之軸向拉 拔力的抵抗力更低。 【發明内容】 因此，本發明之目的，即在提供一種有利於降低施工 成本並能有效提高橫向握裹力與錨定效果之建築用基樁。 本發明的另-目的，在於提供一種上述建築用基捲的 施工方法。 於是，本發明之建築用基樁包含一帽蓋、一自該帽蓋 周緣向下延伸的圍壁、一與該帽蓋相間隔地連設於該圍壁 上的隔板、二對向貫穿該圍壁的固^孔，&多數貫穿該圍 壁的釋壓孔。 中，該圍壁與該帽蓋相配合界定出一置放空間而 该隔板將該置放空間區隔成—位於該帽蓋與該隔板之間的 上置放部，及一與該上置放部相間隔且形成有一相反於該 Μ方向之開口的下置放部’該二以孔是與該上置放部 201247971 相連通，而每一釋壓孔則是與該下置放部相連通。 再者，本發明建築用基樁的施工方法是用以施作前述 之建築用基樁，該建築用基樁的施工方法依序包含一鑽挖 步驟、一注·漿步驟、一插植步驟、一開挖步驟、一固定步 驟，及一灌注步驟。 該鑽挖步驟是於地面鑽挖一設定深度之植入孔；該注 漿步驟是於該植入孔中灌注水泥漿；該插植步驟是將該建 築用基樁插入已灌注水泥漿之植入孔中，並使該建築用基 樁界疋有上置放部的圍壁凸出於地面；該開挖步驟是先行 切割去除該帽蓋，使該上置放部與外界連通，並將一鋼筋 籠置入該上置放部内；該固定步驟是將一固定件同時穿置 於該二固定孔與該鋼筋籠中，以錨定該鋼筋籠與該圍壁； 該灌注步驟將水泥漿灌注於該上置放部中以固結該固定件 、鋼筋籠與該圍壁。 本發明之功效在於利用該隔板避免該植入孔内之水泥 漿流入該上置放部中；再利用該固定件同時穿置於該二固 定孔與該鋼筋籠中以錨定該鋼筋籠與該圍壁，提高該鋼筋 籠的錨定效果並增加拉拔抵抗力與承載力；而所述釋壓孔 不但能避免發生管湧現象，在水泥漿凝固後更能提高該建 築用基樁的橫向握裹力。 【實施方式】 有關本發明之前述及其他技術内容、特點與功效，在 以下配合參考圖式之二個較佳實施例的詳細說明中，將可 清楚的呈現。 201247971 在本發明被詳細描述之前，要注意的是，在以下的說 明内容中，類似的元件是以相同的編號來表示。 參閱圖5、6，本發明之建築用基樁3的第一較佳實施 例’包含一帽蓋31、一自該帽蓋31周緣向下延伸的圍壁 32、一與該帽蓋31相間隔地連設於該圍壁32上的隔板33 、二對向貫穿該圍壁32的固定孔34，及多數貫穿該圍壁 32的釋壓孔35。 該圍壁32與該帽蓋3 1相配合界定出一置放空間36， 而a亥隔板3 3將該置放空間3 6區隔成一位於該帽蓋3 1與兮 隔板3 3之間的上置放部3 61 ’及一與該上置放部3 61相間 隔且形成有一相反於該帽蓋31方向之開口 362的下置放部 363 ’該隔板33與該帽蓋31之間的距離小於該隔板33與 該下置放部363之開口 362之間的距離，於本較佳實施例 中’該隔板33與該帽蓋3 1之間的距離是20〇〇mm。 該二固定孔34是與該上置放部361相連通，而每一釋 壓孔35則是與該下置放部363相連通，於本較佳實施例中 ’所述釋壓孔35是兩兩相對應地沿該圍壁32的長度方向 形成於該圍壁32上。 參閱圖7並以圖8A〜8F辅助說明圖7，本發明建築用 基樁的施工方法之較佳實施例，依序包含一鑽挖步驟4ι、 一注漿步驟42、一插植步驟43、一開挖步驟44、一固定步 驟45，及一灌注步驟46。 在此要特別說明的是，本實施例是用以施作上述建築 用基播3的較佳實施例’所以本實施例中所提及有關建築 201247971 用基樁3的結構即是上述建築用基樁3的結構不在此加 以贅述。 該鑽挖步驟41是於地面鑽挖一設定深度之植入孔5 1 ( 如圖8A所示）；該注漿步驟42是於該植入孔51中灌注水 泥漿52(如圖8B所示）；該插植步驟43是將該建築用基樁3 插入已灌注水泥漿52之植入孔51中，並使該建築用基樁3 界定有該上置放部361的圍壁32(即相當於習知所述之樁頭） 凸出於地面，此時，水泥漿52可經由該建築用基樁3底部 之開口 362流入該下置放部363中，而該隔板33則可以避 免自该開口 362流入的水泥漿52流進該上置放部361中， 同時，所述釋壓孔35則可排出該下置放部363中的空氣而 減少管潘現象的產生（如圖8C所示），避免水泥t 52從底部 之開3 62 入時包覆空氣與水分，而造成水泥疲5 2容易 產生未完全乾固的情況。 該開挖步驟44是先行切割去除該帽蓋31，使該上置放 部361與外界連通，然後再將_鋼筋籠53置人該上置放部 361内（如ϋ 8D户斤示）；再配合參閱目8£及圖9，該固定步 驟45疋將-固定件54同時穿置於該二固定孔34與該鋼筋 籠53中，以錨定該鋼筋籠53與該圍壁32 ;該灌注步驟牝 是如圖8F所示’將水泥漿52’灌注於該上置放部36ι中以 固結該固定件54、鋼筋籠53與該圍壁32。 於本較佳實施例中，該固定步驟45中的固定件54是 一加勁鋼筋，而該注聚步驟42的水泥t 52與灌注步驟46 中的水泥漿52,皆是膨脹水泥。 201247971 因此，藉由上述，本發明建築用基樁3及其施工方法 ’於實際應用上確實具有下列功效： 1 -施作簡便快速且成本低： 由於°亥建桌用基捲3於插植步驟43中插入已灌注 水泥衆52之植入孔51日寺，即同時令該建築用基樁3之 具有上置放部361的圍壁32(即相當於習知所述之樁頭） 凸出於地面，且再藉由該隔板33之阻擋，使得自該建 築用基樁3底部之開口 362流入的水泥漿52無法流進 該上置放部361中，因此本發明並不需如習知必須還要 再開挖建築用基樁！之管體η頂部外周緣的周邊土壤 先使樁頭露出來，然後再清除樁頭内混合有土壤之劣質 疑土 1 〇〇等作業，所以可以有效節省前述開挖及清除 之作業時間與費用，簡化施工程序、減少所需人力與機 具’ ^快施工速度降低施工成本，發明人於施工場所經 過精算約能降低一半的施工成本。 2.提高鋼筋籠53的拉拔抵抗力與承載力： 利用將該固定件54穿置於該二固定孔34中，以錯 定該鋼筋籠53與該圍壁32，因此當進行灌注步驟料而 :水泥聚52,灌注於該上置放部361中時，水泥衆μ，即 :流入該固定孔34與固定件54之間的間隙，而同時包 =結合該鋼筋籠53、該圍壁32,以及該固定件 该鋼筋蘢53、_ III辟π α 相壁32 ’及該固定件54三者之間達到 ^定效果’以提高該鋼筋籠Μ的拉拔抵抗力與 ，以及增加該鋼筋籠53與該建築用基樁3之間 201247971 的橫向握裹力，有效避免該鋼筋£ 53目外來之轴向拉 拔力或側向力而產生鬆脫或是側向位移等現象。 3.提高建築用基樁3與水泥漿52之間的橫向握襄力： 由於該建築用基樁3於插植步驟43中插入已灌注 水泥漿52之植入孔51時，水泥聚52可經由該建築用 基樁3底部之開口 362流入該下置放部363令，並貫穿 流經該等釋壓孔35而同時包覆結合該圍壁32之内、外 表面，有效增加建築用基樁3與水泥聚52之間的接觸 面積，進而提高該建築用基樁3與水泥漿52之間的橫 向握裹力，同時亦相對提高該建築用基樁3之軸向拉拔 抵抗力。 參閱圖10,本發明之建築用基樁3的第二較佳實施例 ，大致是與該第一較佳實施例相同，不相同的地方在於·· 該建築用基樁3更包含二分別塞設於每_固^孔34中的撞 蓋37，利用該二擋蓋37能避免在進行插植步驟時植 入孔51周邊的土壤會經該二固定孔34落人該上置放部⑹ 中，以進一步防止在進行灌注步驟46時，灌注於該上置放 部361中的水泥漿52’會混雜有土壤而形成劣質混凝土。 综上所述，本發明建築用基樁3及其施工方法利用該 隔板33避免水泥漿52流入該上置放部361中；再利用該 固定件54穿置於該二固定孔34以錨定該鋼筋籠53與該圍 壁32 ’提高該鋼筋£ 53的錄定效果增加拉拔抵抗力與承載 力；而所述釋壓孔35不但能避免發生管湧現象，在水泥漿 52凝固後更能提高該建築用基樁3的橫向握裹力，故確實 10 201247971 月&達成本發明之目的。 准以上所述者’僅為本發明之較佳實施例而已，當不 能以此限定本發明實施之範圍，即大凡依本發明申請專利 範圍及發明說明内容所作之簡單的等效變化與修飾，皆仍 屬本發明專利涵蓋之範圍内。 【圖式簡單說明】 圖1是一剖視圖，說明一現有的植入式建築用基樁； 圖2是一流程圖，說明一施作現有植入式建築用基樁 的施工方法； 圖3是一局部放大剖視圖，輔助說明圖2 ;

Description of the invention: [Technical field to which the invention pertains] The present invention relates to a pile for construction and a construction method thereof, and particularly to a foundation pile for construction which can effectively reduce cost and improve lateral gripping force and construction thereof method. [Prior Art] When constructing large or high-rise buildings, if there is insufficient stratum strength or soft soil layer, it is often necessary to apply the piles that are driven into the ground to transfer the load of the upper building to the soil bearing layer or the harder site. To increase the safety and stability of the building structure. In addition, 'in recent years, the number of people is still conscious of Zhang', so the construction of the groundcast needs to consider the noise, vibration and air pollution caused by the impact on the surrounding environment during construction. So in recent years, implanted piles have received more and more attention. . Referring to Figure 1, the prior art implanted pile 1 includes a hollow tubular body 11 having a top edge "I. Referring to FIG. 2, the existing implanted pile 1 is constructed by first drilling an implant hole 21 on the ground; then injecting the cement slurry into the implant hole 21; The tube body U of the piled pile is implanted into the implant hole 21, so that the cement slurry in the implant hole 21 enters from the bottom of the tube body and fills the tube body 11, and there is a part of the cement at this time. The slurry 100 overflows from the gap between the tube U and the implantation hole 21 and is mixed with the surrounding soil and then flows back into the tube 11 through the top edge ui, and is adjacent to the top edge in the tube u. The area of U1 (also known as the pile head) is solidified into inferior concrete mixed with soil, and then the implanted pile 1 is allowed to stand for 14 days to be solidified by the cement slurry 100; then the implant is excavated after 201247971 The soil around the outer periphery of the top of the pile, so that the pile head of the implanted pile 1 protrudes outward, and then excavates about 2 meters from the inside of the top edge U1 of the pipe body u to The inferior concrete located in the area of the pipe body u adjacent to the top edge 111 (ie, the pile head described above) is removed; (4) the steel bar 23 is placed through the steel cage 22 And the steel cage 22 is placed in the tubular body 11 such that the two ends of the steel bar 23 straddle the top edge 111 of the tubular body u, so that the steel cage 22 is suspended from the steel bar 23 in a suspended manner. Upper (as shown in a partial enlarged view of FIG. 3); finally, concrete 〇〇 is injected, and the pile 1 and the steel cage 22 are wrapped in the pipe body 11 (as shown in a partially enlarged view of FIG. 4). ) 'This completes the construction of the implanted pile 1 . Existing implantable piles! And its construction method, although it can combine the advantages of low noise 9, low vibration and low air pollution, it still has the following shortcomings to be improved: 1. Time-consuming and costly: due to the implantation of the tube 11 into the plant When entering the hole 21, a part of the cement slurry 100 overflows and flows back from the gap between the tube body and the implantation hole 21, and is mixed with the soil around the implantation hole 21 and then passes through the top edge of the tube body 11. 111 is recirculated into the pipe body u and solidified into inferior concrete 100 mixed with soil. Therefore, the existing implanted foundation pile i needs to be removed after excavating the surrounding soil around the top periphery of the pile to expose the pile head. The inferior concrete 100 in the pipe body 11 of the t causes the time cost and labor cost of the existing implanted pile 1 to be high. 2. The tinning effect of the steel cage 22 is not good: since the steel cage 22 is only suspended in the pipe body u 4 201247971 by the steel bar 23, the reinforcing bar 23 supports the weight of the steel cage 22 only by the central portion thereof. However, the above method cannot be anchored firmly and surely. 3. The transverse gripping force of the tubular body 11 is also insufficient: the base piles implanted in the implanted holes 21 are in contact with the cement pulp only by the inner and outer surfaces of the tubular body u, respectively, The outer surfaces are not connected to each other and lack lateral gripping force, so that the lateral grip strength of the tubular body can be lower after the cement slurry 100 is solidified, when the upper layer of the implanted pile 1 is When the structure is subjected to lateral or axial force such as wind or earthquake force, it will easily cause lateral displacement or even looseness of the steel cage 22, especially for the axial pull-out force of the pile pile. low. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a building foundation pile which is advantageous for reducing construction cost and effectively improving lateral gripping force and anchoring effect. Another object of the present invention is to provide a method of constructing the above-described base roll for construction. Therefore, the foundation pile for construction of the present invention comprises a cap, a surrounding wall extending downward from the periphery of the cap, a partition connected to the surrounding wall spaced apart from the cap, and two opposite sides The fixing holes of the surrounding wall, & most of the pressure-relieving holes penetrating the surrounding wall. The surrounding wall cooperates with the cap to define a placement space, and the partition partitions the placement space into an upper placement portion between the cap and the partition, and The upper placing portions are spaced apart and are formed with a lower placing portion opposite to the opening of the weir direction. The two holes are connected to the upper placing portion 201247971, and each of the pressure releasing holes is placed with the lower placing portion The departments are connected. Furthermore, the construction method of the foundation pile for construction of the present invention is for applying the above-mentioned foundation pile for construction, and the construction method of the pile for construction includes a drilling step, a injection step, and a planting step. , an excavation step, a fixed step, and a perfusion step. The drilling step is to drill a set depth of the implant hole in the ground; the grouting step is to inject cement slurry into the implant hole; the planting step is to insert the building foundation pile into the planted cement slurry. Inserting into the hole, and causing the surrounding wall of the building with the upper placing portion to protrude from the ground; the excavating step is to cut and remove the cap first, so that the upper placing portion communicates with the outside, and a reinforcing cage is inserted into the upper placing portion; the fixing step is to insert a fixing member into the two fixing holes and the reinforcing cage at the same time to anchor the reinforcing cage and the surrounding wall; The upper portion is infused to fix the fixing member, the reinforcing cage and the surrounding wall. The utility model has the advantages that the separator is used to prevent the cement slurry in the implantation hole from flowing into the upper placement portion; and the fixing member is simultaneously inserted into the two fixing holes and the steel cage to anchor the steel cage And the surrounding wall, the anchoring effect of the steel cage is increased and the drawing resistance and the bearing capacity are increased; and the pressure releasing hole not only avoids the piping phenomenon, but also improves the building foundation pile after the cement slurry solidifies. Horizontal grip. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. 201247971 Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to Figures 5 and 6, the first preferred embodiment of the building pile 3 of the present invention comprises a cap 31, a surrounding wall 32 extending downward from the periphery of the cap 31, and a cap 31. A partition 33 that is spaced apart from the surrounding wall 32, two fixing holes 34 that penetrate the surrounding wall 32, and a plurality of pressure releasing holes 35 that penetrate the surrounding wall 32. The surrounding wall 32 cooperates with the cap 31 to define a space 36, and the a partition 3 3 partitions the space 36 into a cap 31 and a partition 33 The upper placement portion 3 61 ' and a lower placement portion 363 which is spaced apart from the upper placement portion 3 61 and has an opening 362 opposite to the direction of the cap 31. The spacer 33 and the cap 31 The distance between the spacer 33 and the opening 362 of the lower placement portion 363 is smaller than the distance between the spacer 33 and the cap 31 in the preferred embodiment. Mm. The two fixing holes 34 are in communication with the upper placing portion 361, and each of the pressure releasing holes 35 is in communication with the lower placing portion 363. In the preferred embodiment, the pressure releasing hole 35 is Two pairs are correspondingly formed on the surrounding wall 32 along the length direction of the surrounding wall 32. Referring to FIG. 7 and FIG. 7A to FIG. 8F, FIG. 7 is a preferred embodiment of a method for constructing a pile for building according to the present invention, which includes a drilling step 4, a grouting step 42, a planting step 43, An excavation step 44, a fixing step 45, and a filling step 46. It should be particularly noted that the present embodiment is a preferred embodiment for applying the above-described construction base 3. Therefore, the structure of the reference pile 3 for the building 201247971 mentioned in this embodiment is the above-mentioned construction. The structure of the pile 3 will not be described here. The drilling step 41 is to drill a set depth of the implant hole 5 1 on the ground (as shown in FIG. 8A ); the grouting step 42 is to inject the grout 52 into the implant hole 51 (as shown in FIG. 8B ). The planting step 43 is to insert the building foundation pile 3 into the implantation hole 51 of the poured cement slurry 52, and the building foundation pile 3 defines the surrounding wall 32 of the upper placement portion 361 (ie, Corresponding to the conventionally described pile head) protruding from the ground, at this time, the cement slurry 52 can flow into the lower placement portion 363 through the opening 362 at the bottom of the construction foundation pile 3, and the partition plate 33 can be avoided. The cement slurry 52 flowing from the opening 362 flows into the upper placing portion 361, and at the same time, the pressure releasing hole 35 can discharge the air in the lower placing portion 363 to reduce the occurrence of the tube pan phenomenon (Fig. 8C). As shown in the figure), it is avoided that the cement t 52 is covered with air and moisture when it enters from the bottom, and the cement fatigue is likely to cause incomplete drying. The excavation step 44 is to cut and remove the cap 31 in advance, so that the upper placing portion 361 is in communication with the outside, and then the _ steel cage 53 is placed in the upper placing portion 361 (such as ϋ 8D); Referring to FIG. 8 and FIG. 9, the fixing step 45 疋 inserts the fixing member 54 into the two fixing holes 34 and the reinforcing cage 53 to anchor the reinforcing cage 53 and the surrounding wall 32; The infusion step 灌注 is to inject the cement slurry 52' into the upper placement portion 36i as shown in FIG. 8F to consolidate the fixing member 54, the reinforcing cage 53 and the surrounding wall 32. In the preferred embodiment, the fixing member 54 in the fixing step 45 is a stiffening bar, and the cement t 52 of the injecting step 42 and the grout 52 in the infusion step 46 are both expanded cement. 201247971 Therefore, by the above, the foundation pile 3 for construction of the present invention and the construction method thereof have the following effects in practical application: 1 - Simple and quick to implement and low in cost: Since the base table 3 for planting is used for planting In step 43, the implant hole 51 of the poured cement 52 is inserted, that is, the surrounding wall 32 of the foundation pile 3 having the upper placing portion 361 (that is, the pile head corresponding to the conventional one) is convex at the same time. Out of the ground, and by the blockage of the partition 33, the cement slurry 52 flowing in from the opening 362 at the bottom of the building pile 3 cannot flow into the upper placement portion 361, so the present invention does not need to It is customary to re-excavate building foundation piles! The soil around the outer periphery of the top of the pipe body η first exposes the pile head, and then removes the inferior soil 1 mixed with the soil in the pile head, so that the operation time and cost of the excavation and removal can be effectively saved. Simplify the construction procedure and reduce the manpower and equipment required. ^ Quick construction speed reduces construction costs. The inventor can reduce the construction cost by half in the construction site. 2. Increasing the drawing resistance and bearing capacity of the reinforcing cage 53: the fixing member 54 is placed in the two fixing holes 34 to misalign the reinforcing cage 53 and the surrounding wall 32, so when the pouring step is performed And: the cement gathers 52, when poured in the upper placement portion 361, the cement is μ, that is, flows into the gap between the fixing hole 34 and the fixing member 54, and at the same time, the package = the reinforcing steel cage 53, the surrounding wall 32, and the fixing member, the reinforced concrete 茏53, _III π α phase wall 32 ′ and the fixing member 54 achieve a certain effect 'to improve the drawing resistance of the steel cage 与, and increase the The lateral gripping force of the 201247971 between the steel cage 53 and the building foundation pile 3 effectively avoids loose or lateral displacement of the outer axial pulling force or lateral force of the reinforcing steel. 3. Increasing the lateral grip force between the building foundation pile 3 and the cement slurry 52: Since the building foundation pile 3 is inserted into the implantation hole 51 of the poured cement slurry 52 in the planting step 43, the cement cluster 52 can be The bottom portion 362 is inserted into the bottom portion 362 through the opening 362 of the bottom of the building pile 3, and flows through the pressure relief holes 35 to simultaneously cover the inner and outer surfaces of the surrounding wall 32, thereby effectively increasing the building base. The contact area between the pile 3 and the cement pile 52 further increases the lateral gripping force between the building pile 3 and the cement slurry 52, and at the same time relatively increases the axial drawing resistance of the building pile 3. Referring to Fig. 10, a second preferred embodiment of the building foundation pile 3 of the present invention is substantially the same as the first preferred embodiment. The difference is that the building foundation pile 3 further includes two separate plugs. The cover 37 is disposed in each of the holes 34, and the second cover 37 can prevent the soil around the insertion hole 51 from falling through the two fixing holes 34 when the planting step is performed (6) In order to further prevent the cement slurry 52' poured into the upper placement portion 361 from being mixed with soil to form inferior concrete when the pouring step 46 is performed. In summary, the foundation pile 3 for construction of the present invention and the construction method thereof use the partition plate 33 to prevent the cement slurry 52 from flowing into the upper placement portion 361; and the fixing member 54 is inserted into the two fixing holes 34 to anchor The reinforcing cage 53 and the surrounding wall 32' increase the recording effect of the reinforcing bar £53 to increase the drawing resistance and the bearing capacity; and the pressure releasing hole 35 can not only avoid the piping phenomenon, but also after the cement slurry 52 solidifies. The lateral gripping force of the building pile 3 can be improved, so it is true that 10 201247971 & The above-mentioned ones are only the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All remain within the scope of the invention patent.
