Description
Technical Field
The present disclosure relates generally to the field of pier pile foundation construction, and more particularly to a tubular pile guide for constructing a pier pile foundation structure.
Background
To date, dock structures mainly include three major categories: gravity type structure, high pile cap type structure and sheet pile structure. The sheet pile structure has the advantages of simple structure, less material consumption and low cost. Sheet pile structures have lower requirements on foundation conditions than gravity type structures. Compared with a high pile cap type structure, the adaptability of the local overload of the sheet pile structure is stronger, and the excavation of the wall front harbor pool can be performed after the sheet pile is driven in the construction process, so that the earth excavation and filling quantity can be greatly reduced.
To further adapt to large deepwater wharfs construction, sheet pile structures have evolved into new forms, such as tube sheet pile composite structures. The tube plate pile combination structure comprises plate piles and tubular piles, wherein the plate piles and the tubular piles are arranged at intervals. Typically, two catches are symmetrically welded to the outside of the tube wall of the tube stake, the catches being elongate ribs and extending along a portion of the length of the tube stake in the direction of the longitudinal axis of the tube stake, the sheet stake being connected to an adjacent tube stake via the catches. In the tube sheet pile combined structure, the pipe piles have strong bending resistance and are used for bearing external force and reducing structural deformation, and the sheet piles are used for retaining soil. Therefore, the tube plate pile combined structure can effectively solve the problems of large pile foundation structure stress and large deformation in deep water wharf construction.
However, in the process of constructing a tubular sheet pile composite structure, there are still the following problems: (1) the problem of pipe pile construction precision. In construction, the pipe piles are first driven into the foundation, and then the sheet piles are driven into the foundation at the pipe pile intervals, so that the sheet piles and the pipe piles are connected with each other in the foundation via the catches. Therefore, the construction precision of the tubular pile in the tube plate pile combined structure directly influences the construction of the sheet pile and the engagement connection quality of the lock catch. If the construction precision of the pipe pile is insufficient, the lock catch is torn in the construction process of the sheet pile, and the sand leakage condition is caused. And (2) the construction difficulty of the tubular pile is increased by special geology. The harder stratum or the existing boulders often cause large deviation in the pipe pile construction process, and the application precision of the pipe pile is difficult to control. (3) The traditional construction method of the large-scale driven pile foundation in land adopts a process of combining a crawler crane and a vibrating hammer with a guide frame to stabilize the pile for positioning, has high requirements on equipment performance, needs high-altitude operation and has great operation risk. Under the condition that geological hard layers exist on the surface layer or the positioning accuracy requirement of the tubular pile is high, the traditional construction process is difficult to meet the requirement. Accordingly, there is a need for further improvements in the pipe pile driving process and related equipment to improve the accuracy of the pipe pile construction.

Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

In some examples, a first element and a second element may refer to the same instance of the element, and in some cases, they may also refer to different instances based on the description of the context.
The terminology used in the description of the various illustrated examples in this disclosure is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context clearly indicates otherwise, the elements may be one or more if the number of the elements is not specifically limited. Furthermore, the term "and/or" as used in this disclosure encompasses any and all possible combinations of the listed items.
When the tubular sheet pile combined structure is constructed, tubular piles are firstly applied to the foundation, and then sheet piles are applied to the foundation at the intervals of the tubular piles, so that the sheet piles and the tubular piles are connected with each other in the foundation through locking catches. In order to ensure that the piles and sheet piles driven into the foundation are well connected at the catches, it is necessary to ensure that the catches of the piles are located at the desired positions. Otherwise, in the process of later piling, the side edge of the sheet pile cannot be successfully jointed with the lock catch of the tubular pile, or even if the sheet pile is jointed, the lock catch of the tubular pile is torn due to dislocation of the side edge of the sheet pile and the lock catch of the tubular pile, and finally the sand leakage condition is caused.
In general, the position of the catches of the tube stake is affected by the position and attitude of the tube stake. It is at least necessary to ensure that the longitudinal axis of the pile is at the desired position during construction and to limit rotation of the pile about its longitudinal axis. The related art includes that the position control of the pipe pile is realized through the cooperation of a measuring instrument and a guiding device. In the process of applying the pipe pile, the position and the posture of the pipe pile are measured by a measuring instrument, and at the same time, the positioning of the pipe pile is adjusted and limited by a guide device according to the measurement result. However, the guide device in the related art has problems of insufficient control accuracy, high design height, difficulty in worker operation, and the like.
The disclosed embodiments provide an improved pipe pile guide so that at least one of the above problems can be overcome.
Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
Fig. 1 illustrates a tubular pile guide 100 for use in construction of a pier pile foundation structure in accordance with an embodiment of the present disclosure. The pipe pile guide 100 is disposed around the pipe pile 10 to be driven into the foundation, and in the process of driving the pipe pile 10, the position and posture of the pipe pile 10 are controlled, and meanwhile, the pipe pile guide 100 can play a role in assisting the pipe pile 10 to break the hard interlayer and stabilize the pile.
The pipe pile guide 100 includes a first guide 110 and a second guide 120. The first guide 110 is located near the ground, and the second guide 120 is disposed above the first guide 110. The first guide 110 and the second guide 120 provide two positioning planes along the longitudinal axis direction of the pipe pile 10, thereby improving the control accuracy of the position and posture of the pipe pile 10.
The first guide 110 further includes a first guide platform 111, a casing 112, and 4 first pipe pile locators 113 mounted on the casing 112. The first guide platform 111 is fixedly mounted near the ground and is provided with a first opening 1111 therethrough. As shown in fig. 1, the casing 112 has one end buried under the ground and the other end protruding from the first guide platform 111 through the first opening 1111 of the first guide platform 111.
The casing 112 is also provided with 4 first pile locators 113. When the pipe pile 10 is applied under the ground, the casing 112 surrounds the pipe pile 10 and restricts and adjusts the position of the pipe pile 10 by 4 first pipe pile locators 113. Specifically, 4 first pile locators 113 are mounted on the outside of the wall of the casing 112. Fig. 2 further shows the layout of the 4 pipe pile locators of fig. 1 in a top view. For clarity of illustration, fig. 2 is not drawn to scale. As shown in fig. 2, the 4 first pile locators 113 are located on the same plane perpendicular to the longitudinal axis of the casing 112 and are spaced apart from each other by 90 degrees around the circumferential direction of the casing 112. Each first tube stake locator 113 includes a first top piece 1131, the first top piece 1131 being configured to: when the pipe pile 10 is disposed within the casing 112, the pipe pile 10 can be positioned by pressing against the pipe wall of the pipe pile 10 through the wall of the casing 112. By including 4 first tube stake positioners 113 spaced 90 degrees apart from each other, the first guide 110 is able to control and adjust the position of the tube stake from 4 directions, giving attention to the stability and flexibility of the position control.
In some embodiments, the first top block 1131 is a rubber columnar roller. The circumferential side walls of the rubber cylindrical rollers press against the pipe wall of the pipe pile 10. Due to the design of the roller structure and the adoption of the flexible rubber material, the anti-corrosion coating on the pipe wall of the pipe pile 10 is prevented from being scratched when the position of the pipe pile 10 is controlled and adjusted.
In a first embodiment, the first guiding means further comprises at least 4 anchor piles 114. As shown in fig. 1, at least 4 anchor piles 114 are anchored to the ground and support the first guiding platform 111.
The second guide 120 includes a second guide platform 121. The second guide platform 121 is fixedly mounted above the first guide 110 at a height higher than the casing 112 and is provided with a second opening 1211 opposite to the first opening 1111 of the first guide platform 111. The tube stake 10 extends upwardly through the second opening 1211 when disposed within the cage 112. The second guide 120 provides a second locating plane along the longitudinal axis of the tube stake 10, further enhancing the control of the tube stake 10. Moreover, the second guide 120 not only serves to locate the position of the pipe stake 10, but also limits rotation of the pipe stake about its longitudinal axis, as compared to the first guide 110.
The above-described limitation of the rotation of the tubular pile about its longitudinal axis is achieved by providing 2 tubular pile rotation limiters 122. As shown in fig. 1 and 2,2 pipe pile rotation limiters 122 are symmetrically installed on the second guide platform 121. When the pipe pile 10 is disposed in the casing 112 and extends upward through the second guide platform 121, the 2 pipe pile rotation limiters 122 are respectively opposed to the 2 catches 11 of the pipe pile 10. Each of the pipe stake rotation limiters 122 includes a limit stop 1221. The stopper 1221 has a stopper groove 1222.
Fig. 3 and 4 further illustrate how the stake rotation limiter 122 fits to the stake 10 and controls rotation of the stake 10 about its longitudinal axis. For clarity of illustration, fig. 3, 4 are not drawn to scale. As shown in fig. 3 and 4, the stopper 1221 can be pressed against the pipe wall of the pipe pile 10 and the lock catch 11 is inserted into the stopper groove 1222 of the stopper 1221 during the pipe pile application. The rotation of the pipe stake 10 about its longitudinal axis is limited by the two catches 11 on the pipe stake 10 being respectively inserted into the limit slots 1222 of the limit stops 1221 of the 2 stake rotation limiters 122.
With continued reference to fig. 3 and 4, one particular embodiment of the tube stake rotation limiter 122 is illustrated. The stopper 1221 of the pipe pile rotation stopper 122 may be embodied as a dumbbell-shaped roller including a roller 1223 and two disks 1224 attached to both ends of the roller 1223, respectively, a gap between the two disks 1224 forming a stopper groove 1222. In order to enable the dumbbell roller to bear against the pipe stake, the pipe stake rotation limiter 122 further includes a bracket 1225 and a slider 1226. The pipe pile rotation limiter 122 is mounted to the second guide platform 121 via a bracket 1225. The slider 1226 is slidably disposed within the interior cavity of the stand 1225, and the dumbbell-shaped rollers are rollably connected to one end of the slider 1226 adjacent the tube stake 10. The pushing member 1227 is connected to an end of the slider 1226 remote from the tube stake 10 and is configured to push the slider 1226 to press the circumferential wall of the disk 1224 of the dumbbell roller against the tube wall of the tube stake 10. In some embodiments, the pushing member 1227 is a screw, and the construction worker may move the slide 1226 within the interior cavity of the bracket 1225 by rotating the screw.
In some embodiments, the second guide 120 further comprises 2 second pipe stake retainers 123. Referring to fig. 2,2 second pile locators 123 and 2 pile rotation limiters 122 are installed at intervals on the second guide platform 121 on the same plane perpendicular to the longitudinal axis of the pipe pile 10 and spaced apart from each other by 90 degrees around the circumferential direction of the pipe pile 10. Each second pipe stake locator 123 includes a second top piece 1231. The second top block 1231 is configured to: when the pipe stake 10 is disposed within the casing 112 and extends through the second guide platform 121, it can be pressed against the pipe wall of the pipe stake 10 to locate the position of the pipe stake 10. By including 2 second pipe stake positioners 123 and 2 pipe stake rotation limiters 122, the second guide 120 can also limit the position of the pipe stake while being able to limit the rotation of the pipe stake 10 about its longitudinal axis, thereby providing two planar positioning along the longitudinal axis of the pipe stake along with the first guide 110, further improving the positioning accuracy of the position of the pipe stake.
In some embodiments, as shown in fig. 2,2 second pipe stake locators 123 and 2 pipe stake rotation limiters 122 of the second guide 120 are staggered with 4 first pipe stake locators 113 of the first guide 110, forming an included angle of 45 degrees between two. The arrangement structure enables the tubular pile to form 8 uniformly distributed position control points in the longitudinal axis direction. All control points are stressed uniformly and matched with each other, so that the stability of the positioning of the tubular pile is improved, and the tubular pile is easy to install and operate.
In some embodiments, the second pipe stake locator 123 has a similar structure to the first pipe stake locator 113. The second top block 1231 is a rubber column roller. The circumferential side walls of the rubber cylindrical rollers press against the pipe wall of the pipe pile 10. Due to the design of the roller structure and the adoption of the flexible rubber material, the anti-corrosion coating on the pipe wall of the pipe pile 10 is prevented from being scratched when the position of the pipe pile 10 is controlled and adjusted.
It will be appreciated that the catches 11 of the tube stake 10 are used to limit rotation of the tube stake 10 about its longitudinal axis. However, to save manufacturing costs, the catches 11 are typically provided only along a portion of the length of the tube stake in the longitudinal direction of the tube stake. That is, the catches 11 are not disposed over the entire length of the tube stake 10, e.g., the catches 11 do not extend near the lower end of the tube stake 10. This results in that the catches 11 are not available to limit rotation of the tube stake 10 about its longitudinal axis, at least at the initial stage of application of the stake 10. The initial stage of the tubular pile is the key period for controlling the positioning precision of the tubular pile.
To address the above, the second guide 120 further includes 2 catch extensions 124. As shown in fig. 3, the shackle extension 124 is an elongated member. In some embodiments, at least one of the 2 shackle extensions 124 is a rebar. The shackle extension member 124 is welded to the outside of the tube wall of the tube stake 10 in the longitudinal direction of the tube stake 10 over the length of the tube stake to which the shackle 11 does not extend, thereby extending the shackle 124 in the longitudinal direction of the tube stake 10. Thus, as shown in the lower part of fig. 3, the stop 1221 of each stake rotation limiter 122 can be pressed against the wall of the stake and the corresponding latch extension 124 inserted into the stop slot 1222 of the stop 1221 to limit rotation of the stake 10 about its longitudinal axis over a length of stake not extended by the latch 11, for example, during initial stake application. The locking and extending piece is simple in structure and easy to install, and therefore the limiting capacity of the second guiding device on the rotation of the tubular pile is further improved in a low-cost mode.
In some embodiments, the pipe pile guide 100 according to the present disclosure may further include a third guide 130. Fig. 5 shows a pipe pile guide 100 comprising a third guide 130. The third guide 130 includes a third guide platform 131 and 4 third pipe pile locators 132 mounted on the third guide platform 131. The third guide platform 131 is fixedly mounted above the second guide 120 and is provided with a third opening 1311 opposite to the second opening 1211 of the second guide platform 121. The pipe stake 10 extends upwardly through the second and third openings 1211, 1311 in sequence when disposed within the casing 112.
In some embodiments, 4 third pipe stake retainers 132 are mounted on the third guide platform 131 on the same plane perpendicular to the longitudinal axis of the pipe stake 10 and spaced 90 degrees from each other about the circumferential direction of the pipe stake 10. Similar to the first pipe stake retainers 113, each third pipe stake retainer 132 includes a third top piece. The third top block is configured to: when the pipe pile 10 is disposed within the casing 112 and extends sequentially through the second and third guide lands 121 and 131, it is possible to press against the pipe wall of the pipe pile 10 to locate the position of the pipe pile 10.
By including 4 third tube stake locators 132, the third guide 130 provides a third plane of location along the longitudinal axis of the tube stake 10. The third guide 130 cooperates with the first guide 110 and the second guide 120 to simultaneously position the pipe pile 10 on three positioning planes, thereby further improving the positioning accuracy of the pipe pile. In addition, the third guiding device 130 further shares the stress of the first guiding device 110 and the second guiding device 120, in particular reduces the stress of the 2 tubular pile rotation limiters 122 of the second guiding device 120, thereby avoiding the deviation of the lock catch 11 of the tubular pile 10 caused by the overlarge stress of the tubular pile rotation limiters 122, and further improving the capability of limiting the rotation of the tubular pile.
In some embodiments, the third guide 130 is in an openable and closable structure on at least one side. The openable and closable structure is configured to be openable to form a lateral window in communication with the third opening 1311, thereby facilitating entry of the pipe stake into the third opening 1311 of the third guide 130 via the lateral window. In this way, when the pipe pile 10 is lifted to place the pipe pile in the pipe pile guide 100, the lifting height of the pipe pile is not increased due to the provision of the third guide 130. Through setting up but the structure that opens and shuts, both improved control accuracy, avoided guider too high again to lead to the problem that the construction degree of difficulty increases.
In some embodiments, the third guide 130 is further provided with a protective cover on the top so as to protect workers from being injured by falling sand or the like during operation.
