Description

Technical Field

[0001] This utility model relates to the field of combined support structure technology, and in particular to a co-located combined pile wall support structure in strata. Background Technology

[0002] In stratum excavation and underground engineering construction, in-situ composite pile walls, as a form of support, are formed by setting continuous piles in the stratum and connecting them to form a wall. They are mainly used to support the stratum around the excavation face, prevent soil collapse, control stratum deformation, and thus create a safe working space for underground engineering construction. In-situ composite pile wall support structures are specific structural forms developed on the basis of in-situ composite pile walls. They form a complete support system by combining continuous walls and columns with connecting mechanisms, achieving three-dimensional support for the stratum and adapting to engineering needs under different geological conditions.

[0003] A search revealed Chinese patent publication number CN209923935U, which discloses a co-located composite pile wall support structure in soft-upper-hard-lower strata. The structure includes an upper pile body and a lower pile body located below the upper pile body. Part of the upper pile body is embedded in the bedrock, and part of the lower pile body is also embedded in the bedrock, with the other part extending into the foundation. This invention reduces the construction difficulty of conventional continuous walls and bored piles in hard rock, accelerates construction efficiency, and lowers project costs. Compared to conventional suspended pile wall technology, it is suitable for areas where the use of prestressed anchor cables is restricted, reduces the excavation width of the foundation pit, lowers the construction risk of the foundation pit, and avoids water leakage problems caused by anchor cables. However, in actual use, this device is only supported by the lower column, and the single support structure results in the column not being able to provide stable support. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a co-located composite pile wall support structure in the stratum, which aims to improve the problem that the existing equipment is only supported by the lower column, and the single support structure leads to the inability of the column to provide stable support.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a co-located composite pile wall support structure in strata, comprising a continuous wall, wherein columns are fixedly connected to the bottom left and right sides of the continuous wall, a connecting mechanism is provided at the top of the outer wall of each of the two columns, a ring is fixedly connected to the lower middle part of the outer wall of each of the two columns, a support mechanism is provided at the bottom outer side of each of the two columns, the connecting mechanism comprises two horizontal plates, the two horizontal plates are respectively fixedly connected to the top outer side of the columns, two sliding grooves are opened on the bottom left and right sides of the continuous wall, and slots are connected to the left and right sides of the interior of the sliding grooves, connecting blocks are fixedly connected to the top left and right sides of the two horizontal plates, moving grooves are opened on the left and right sides of the multiple connecting blocks, and slots are slidably connected to the left and right sides of the interior of the multiple moving grooves, threaded rods are rotatably connected to the bottom left and right sides of the two horizontal plates, the top ends of the multiple threaded rods sequentially penetrate the horizontal plates and the moving grooves, and push blocks are threadedly connected to the outer walls of the multiple threaded rods, an adjustment component is provided on the adjacent side of each of the two rings, and a fixing component is provided on the front side of the adjustment component.

[0006] Through the above technical solution: the columns on the left and right sides of the bottom of the diaphragm wall are stably connected by the top connecting mechanism. Two horizontal plates are fixed to the top of the outer side of the column. After the top connecting block is inserted into the sliding groove at the bottom of the diaphragm wall, the threaded rod at the bottom of the horizontal plate is rotated. The top of the threaded rod passes through the horizontal plate and the moving groove, which drives the push block to move in the moving groove and pushes the locking block into the locking groove, thus completing the locking and fixing of the horizontal plate and the diaphragm wall. The ring at the lower middle part of the outer wall of the column is adapted to different spacing requirements through the adjustment component. The connecting plate of the left ring slides in the groove of the connecting plate one and connects to the connecting plate of the right ring two. After adjustment, the fixing bolt is tightened through the fixing hole of the connecting plate one to lock the position of the ring. The bottom support mechanism on the outer side of the column increases the support force and achieves stable support.

[0007] As a further description of the above technical solution: The support mechanism includes two fixing rings. The inner sides of the two fixing rings are fixedly connected to the outer bottom of the corresponding columns. The outer sides of the two fixing rings are provided with circular grooves. Multiple arc-shaped blocks are slidably connected inside the two circular grooves. A fixing block is fixedly connected to one side of the multiple arc-shaped blocks. A cylinder is slidably connected to the top of the multiple fixing blocks. The bottom end of the multiple cylinders passes through the fixing blocks and is rotatably connected to a support foot. A limit bolt is rotatably connected to one side of the multiple fixing blocks. One end of the multiple limit bolts passes through the fixing blocks and fits against the outer side of the cylinder. A positioning component is provided at the top of the two fixing rings, and a reinforcing component is provided at the bottom of the two fixing rings.

[0008] Through the above technical solution: the fixing ring of the bottom support mechanism on the outer side of the column adjusts the position of the support foot through the arc block in the circular groove. After the limit bolt fixes the column, the positioning bolt is screwed into the positioning hole to fix the arc block. The reinforcing plate transfers the load of the fixing ring to the column to achieve stable support.

[0009] As a further description of the above technical solution: The adjustment assembly includes a first connecting plate, the left side of which is fixedly connected to the right side of the left circular ring. A groove is provided on the right side of the first connecting plate, and a second connecting plate is slidably connected inside the groove. The right side of the second connecting plate is fixedly connected to the left side of the right circular ring.

[0010] The above technical solution allows for adjustment of the horizontal distance between the left and right rings by sliding the connecting plate two within the groove, adapting to different formation pressure distributions or construction space requirements.

[0011] As a further description of the above technical solution: The fixing component includes a fixing bolt, the rear end of which is rotatably connected to the front left end of the connecting plate 2. The front side of the connecting plate 1 has multiple fixing holes.

[0012] Through the above technical solution: after the adjustment component completes the adjustment of the ring spacing, the rear end of the fixing bolt is passed through the corresponding fixing hole and tightened, which can fix the connecting plate one and the connecting plate two, prevent the ring from shifting due to the ground load, and ensure the stability of the support system in the middle of the support structure.

[0013] As a further description of the above technical solution: The positioning assembly includes multiple positioning bolts, the bottom ends of which are rotatably connected to the top of the corresponding arc-shaped block, and multiple positioning holes are provided on the top of the two fixing rings.

[0014] Through the above technical solution: when the support mechanism is working, the arc-shaped block can slide radially in the circular groove outside the fixed ring to adjust the circumferential position of the support foot. After the adjustment is completed, the positioning bolt is screwed into the positioning hole to lock the position of the arc-shaped block in the circular groove, so that the support foot can stably support the ground according to the design layout and avoid the support point from shifting due to the sliding of the arc-shaped block.

[0015] As a further description of the above technical solution: The reinforcement component includes two discs, the inner sides of which are fixedly connected to the outer bottom of the column, and multiple reinforcement plates are fixedly connected to the top of each of the two discs. The tops of the multiple reinforcement plates are fixedly connected to the bottom of the corresponding fixing rings.

[0016] Through the above technical solution, the component transfers the load borne by the fixing ring to the disk and column through the reinforcing plate, enhances the connection strength between the fixing ring and the bottom of the column, and prevents the fixing ring from deforming or falling off due to long-term stress.

[0017] As a further description of the above technical solution: The rear end of the fixing bolt passes through the corresponding fixing hole, and the size of the fixing bolt and the fixing hole are matched.

[0018] The above technical solutions ensure that there is no excessive gap between the fixing bolts and the fixing holes, prevent the fixing components from loosening due to vibration or load fluctuations, guarantee the locking effect after the ring spacing is adjusted, and maintain the stability of the middle part of the support structure.

[0019] As a further description of the above technical solution: The left and right sides of the two push blocks are respectively attached to one side of the corresponding card block, and the multiple card blocks are respectively slidably connected to the inside of the corresponding card slot.

[0020] Through the above technical solution: when the threaded rod is rotated, the push block moves along the axial direction of the threaded rod and pushes the locking block into the locking groove at the bottom of the continuous wall, so that the horizontal plate and the continuous wall are locked together and fixed.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the push block is moved by rotating the threaded rod, so that the locking block slides into the locking groove to complete the connection between the horizontal plate and the continuous wall. At the same time, the sliding connecting plate adjusts the ring spacing and locks it with the fixing bolt, thus realizing a firm connection between the column and the top of the continuous wall and the adjustable ring spacing, which enhances the structural stability and prevents the bottom of the column from shifting and settling.

[0022] 2. In this utility model, the position of the support point is adjusted by sliding the arc block in the groove of the fixed ring. After the cylinder drives the support foot to move up and down to fit the terrain, it is locked with the limit bolt. Then the arc block is fixed with the positioning bolt. The reinforcing plate connects the fixed ring and the column, which realizes the adjustment of the support foot position and height according to the stratum terrain and the stable transmission of load, thereby enhancing the stability of the bottom of the support structure.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 4In one embodiment of this utility model: Columns 2 are fixedly connected to the bottom left and right sides of the diaphragm wall 1, forming a basic support frame to withstand lateral pressure from the ground.

The bottom of the two horizontal plates 301 The left and right sides are connected by rotating threaded rods 306, which can drive the push block 307 to move when rotating. The tops of multiple threaded rods 306 pass through the horizontal plate 301 and the moving groove 305, which can convert the rotation of the threaded rods 306 into the axial movement of the push block 307. The outer walls of the multiple threaded rods 306 are threaded to the push block 307, which can push the locking block 308 to slide when it moves. An adjustment component 309 is set on one side of the two rings 4 adjacent to each other, which can adapt to the adjustment requirements of the spacing of the column 2 under different working conditions. A fixing component 310 is set on the front side of the adjustment component 309, which can fix the position of the ring 4 after adjustment. The adjustment component 309 includes a connecting plate 3091, the left side of which is fixed to the left ring 4. On the right side, a groove 3092 is provided on the right side of the connecting plate 3091, which can be used as an adjustment base connection component to accommodate the sliding of the connecting plate 3093, thereby realizing the spacing adjustment. The connecting plate 3093 is slidably connected inside the groove 3092, and its right side is fixed to the left side of the right ring 4, and can move with the right ring 4 to realize the dynamic adjustment of the spacing. The fixing component 310 includes a fixing bolt 3101, the rear end of which is rotatably connected to the front left end of the connecting plate 3093, and can pass through the fixing hole 3102 to achieve locking. Multiple fixing holes 3102 are provided on the front side of the connecting plate 3091, which can cooperate with the fixing bolt 3101 to achieve fixing in different adjustment positions. Specifically, in the connecting mechanism 3 at the top of the bottom column 2 of the continuous wall 1, the horizontal plate 301 is fixed to the top of the outer side of the column 2, and its top connecting block 304 is inserted into the bottom sliding groove 302 of the continuous wall 1. Rotating the threaded rod 306 causes the push block 307 to push the locking block 308 into the locking groove 303 to complete the locking. The lower middle ring 4 of the outer wall of the column 2 is adjusted to the spacing by the adjusting component 309. The connecting plate 3091 of the left ring 4 is slidably connected to the connecting plate 3092 of the right ring 4 in the groove 3092. 93. After adjustment, use the fixing bolt 3101 to pass through the fixing hole 3102 of the connecting plate 3091 and tighten it. The fixing ring 501 of the bottom support mechanism 5 on the outside of the column 2 drives the fixing block 504 and the cylinder 505 to adjust the height of the support foot 506 through the arc block 503 in the circular groove 502. After the limit bolt 507 is fixed, the positioning bolt 5081 is screwed into the positioning hole 5082 to fix the arc block 503. The reinforcing plate 5092 connects the disc 5091 and the fixing ring 501 to enhance the support.

[0027] Reference Figure 2 and Figure 5The support mechanism 5 includes two fixing rings 501, whose inner sides are fixed to the bottom of the corresponding outer side of the column 2, realizing the bottom connection between the support mechanism 5 and the column 2, providing a bottom support foundation for the entire support structure. Both fixing rings 501 have circular grooves 502 on their outer sides, providing sliding tracks for the arc-shaped blocks 503, allowing them to move radially along the grooves 502 to adapt to different support requirements. Multiple arc-shaped blocks 503 are slidably connected inside the two circular grooves 502, adjusting the position and number of support points by sliding the arc-shaped blocks 503, enhancing the adaptability of the support mechanism 5. A fixing block 504 is fixedly connected to one side of each arc-shaped block 503, transferring the position of the arc-shaped blocks 503 to the fixing block 504, providing a mounting surface for subsequent support components. The structure comprises multiple fixed blocks 504, each top of which is slidably connected to a cylinder 505. The height of the support foot 506 is adjusted by sliding the cylinder 505 up and down to adapt to different terrain surfaces. The bottom ends of the cylinders 505 pass through the fixed blocks 504 and are rotatably connected to the support foot 506, allowing the support foot 506 to rotate according to the ground angle when in contact with the ground, ensuring a tight fit and improving support stability. Each fixed block 504 has a rotatably connected limit bolt 507 on one side, one end of which passes through the fixed block 504 and fits against the outside of the cylinder 505. After the cylinder 505 is adjusted to the appropriate height, it is locked to prevent vertical movement. Positioning components 508 are provided at the top of the two fixing rings 501 to position the sliding arc-shaped block 506. 03. Positioning is performed to prevent it from sliding freely within the circular groove 502. Reinforcing components 509 are installed at the bottom of the two fixing rings 501 to enhance the connection strength between the fixing rings 501 and the column 2, improving the overall stability of the support mechanism 5. The positioning component 508 includes multiple positioning bolts 5081, the bottom of which is rotatably connected to the top of the corresponding arc-shaped block 503. The position of the arc-shaped block 503 is fixed by screwing them into the positioning holes 5082 at the top of the fixing rings 501. The bottom ends of the multiple positioning bolts 5081 are all rotatably connected to the top of the corresponding arc-shaped block 503, adapting to the angle changes of the arc-shaped block 503 during fixing, ensuring that the positioning bolts 5081 can be accurately screwed into the positioning holes 5082. Multiple positioning holes 50 are opened at the top of the two fixing rings 501. 82, in conjunction with positioning bolt 5081, positions the arc-shaped block 503 at different locations. The reinforcing component 509 includes two discs 5091, the inner sides of which are fixed to the bottom of the outer side of the column 2, serving as the connection base between the reinforcing plate 5092 and the column 2, transferring the load to the column 2. Multiple reinforcing plates 5092 are fixedly connected to the top of each of the two discs 5091, and the fixing ring 501 is connected to the disc 5091 through the reinforcing plate 5092, enhancing the structural strength and stability of the fixing ring 501. The tops of the multiple reinforcing plates 5092 are respectively fixed to the bottom of the corresponding fixing ring 501, so that the load on the fixing ring 501 can be transferred to the disc 5091 and the column 2 through the reinforcing plate 5092, realizing the distributed transfer of the load. Specifically, when the support mechanism 5 is working, the inner sides of the two fixing rings 501 are fixed to the bottom of the outer side of the column 2. Multiple arc-shaped blocks 503 within the outer circular groove 502 can slide along the groove. The cylinder 505, slidably connected to the top of the fixing block 504 on one side of the arc-shaped block 503, can be adjusted up and down. The support foot 506, rotatably connected to the bottom of the cylinder 505, contacts different ground surfaces. After adjusting to a suitable height, the limiting bolt 507 on one side of the fixing block 504 is rotated, causing it to pass through the fixing block 504 and fit against the outer side of the cylinder 505 to fix its position. The positioning assembly 508... Multiple positioning bolts 5081 are rotatably connected to the top of the arc-shaped block 503 at their bottom ends. They are screwed into the positioning holes 5082 on the top of the fixing ring 501 to lock the position of the arc-shaped block 503 in the circular groove 502. The inner sides of the two discs 5091 of the reinforcing component 509 are fixed to the bottom of the outer side of the column 2. Multiple reinforcing plates 5092 on the top of the discs 5091 are respectively fixed to the bottom of the corresponding fixing rings 501. The reinforcing plates 5092 enhance the connection strength between the fixing rings 501 and the column 2, so that the load transmitted by the support foot 506 is stably transmitted to the column 2 and the ground.

[0028] Reference Figure 4 and Figure 5 The rear end of the fixing bolt 3101 passes through the corresponding fixing hole 3102, which can connect and fix the adjusted connecting plate 1 3091 and connecting plate 2 3093 to ensure the stability of the ring 4 spacing. The size of the fixing bolt 3101 and the fixing hole 3102 are matched to ensure that the fixing bolt 3101 fits tightly with the fixing hole 3102 after passing through, and avoids loosening of the connection. The left and right sides of the two push blocks 307 are respectively attached to one side of the corresponding card block 308. When the push block 307 moves, it can push the card block 308 to slide in the moving groove 305 to realize the position adjustment of the card block 308. Multiple card blocks 308 are respectively slidably connected to the inside of the corresponding card groove 303, so that the card block 308 can slide into the card groove 303 to form a carding structure, which fixes the horizontal plate 301 to the continuous wall 1 to ensure the effective transfer of the top load of the support structure. Specifically, after the fixing bolt 3101 passes through the fixing hole 3102 of the connecting plate 1 3091 and is tightened, the sliding adjustment connecting plate 2 3093 can be locked with the connecting plate 1 3091, thereby fixing the relative position of the left and right rings 4, ensuring the stability of the spacing in the middle of the column 2 in the support structure, preventing the rings 4 from shifting due to ground pressure, enhancing the integrity and deformation resistance of the structure. The push block 307 is threadedly connected to the threaded rod 306. When the threaded rod 306 is rotated, the push block 307 moves along the axial direction of the threaded rod 306, and its left and right sides fit against the locking block 308 and push the locking block 308 to slide in the moving groove 305. After the locking block 308 slides into the locking grooves 303 on both sides of the sliding groove 302 at the bottom of the continuous wall 1, the horizontal plate 301 is locked and fixed to the continuous wall 1, realizing the connection between the column 2 and the top of the continuous wall 1.

[0029] Working Principle: When using the in-situ composite pile wall support structure in this stratum, the columns 2 fixedly connected to the bottom left and right sides of the diaphragm wall 1 are stably connected through the top connecting mechanism 3. Two horizontal plates 301 are fixed to the top of the outer side of the columns 2 respectively. The connecting blocks 304 on the top left and right sides of the horizontal plates 301 need to be precisely inserted into the sliding grooves 302 opened on the bottom left and right sides of the diaphragm wall 1. At this time, rotate the threaded rod 306 rotatably connected to the bottom left and right sides of the horizontal plates 301. The top of the threaded rod 306 passes through the moving grooves 305 opened on the left and right sides of the horizontal plates 301 and the connecting blocks 304. The push block 307 with its outer wall threaded connection will move axially along the threaded rod 306 in the moving groove 305. When the push block 307 moves, it pushes the locking block 308 to slide in the moving groove 305, so that the locking block 308 slides into the locking groove 303 connected on the left and right sides inside the sliding groove 302, thereby completing the locking and fixing of the horizontal plates 301 and the diaphragm wall 1, ensuring that the column 2 is firmly connected to the top of the diaphragm wall 1. The adjustment component 309 on the adjacent side of the ring 4 can adapt to different working conditions. The right side of the connecting plate 3091 fixedly connected to the right side of the left ring 4 has a groove 3092. The connecting plate 3093 fixedly connected to the left side of the right ring 4 slides in the groove 3092. The distance between the two rings 4 can be adjusted by sliding the connecting plate 3093. After adjusting to the appropriate position, it is fixed by the fixing component 310 on the front side of the adjustment component 309. The rear end of the fixing bolt 3101 is rotatably connected to the left front side of the connecting plate 3093. The fixing bolt 3101 is passed through one of the multiple fixing holes 3102 opened on the front side of the connecting plate 3091 and tightened to fix the connecting plate 3091 and the connecting plate 3093, thereby locking the position of the two rings 4. Through the interaction with the stratum, the stability of the entire structure in the stratum is effectively enhanced, preventing displacement or settlement of the bottom of the column 2. Furthermore, when the support mechanism 5 is working, the inner sides of the two fixing rings 501 are fixed to the bottom of the outer side of the column 2. Multiple arc-shaped blocks 503, slidably connected within the circular groove 502 on the outer side of the fixing rings 501, can slide radially along the circular groove 502. A cylinder 505, slidably connected to the top of the fixing block 504 on one side of the arc-shaped block 503, can move up and down. A support foot 506, rotatably connected to the bottom of the cylinder 505, can contact the ground surface. By adjusting the height of the cylinder 505 within the fixing block 504, the support foot 506 can be made to fit tightly against different terrains. After adjustment, the limiting bolt 507 on one side of the fixing block 504 is rotated so that one end of it passes through the fixing block 504 and fits against the outer side of the cylinder 505, thus securing the support mechanism. Position the cylindrical column 505 and screw the positioning bolt 5081 into the positioning hole 5082 on the top of the fixing ring 501 to fix the position of the arc block 503 in the circular groove 502 and prevent it from sliding. The inner sides of the two discs 5091 of the reinforcing component 509 are fixed to the bottom of the outer side of the column 2. Multiple reinforcing plates 5092 on the top of the discs 5091 are fixed to the bottom of the corresponding fixing rings 501. The reinforcing plates 5092 enhance the connection strength between the fixing rings 501 and the column 2 and transfer the load on the fixing rings 501 to the discs 5091 and the column 2 through the reinforcing plates 5092. At the same time, the support foot 506 transfers the load to the ground to achieve stable support for the support structure.
