Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support in civil engineering, and particularly relates to a deep foundation pit support structure for civil engineering. Background Technique

[0002] A foundation pit is an earth pit excavated at the designed position of the foundation according to the base elevation and the foundation plane size. In order to prevent the pit wall from collapsing during the excavation process, a support structure for supporting the peripheral wall is usually arranged in the foundation pit. The common foundation pit support structure includes a support plate for inserting into the ground, and the support plate is arranged towards the inner wall of the foundation pit. When the inner wall of the foundation pit here collapses towards the inside of the foundation pit, the support plate can play a certain supporting effect.

[0003] The existing support structure usually fixes the support plate by driving anchor piles into the support after longitudinally attaching the support plate to the foundation pit. With the increasingly unique architectural styles, the right-angle support structures are increasingly unable to meet the support requirements of deep foundation pit projects. At the same time, only driving anchor piles between the support plate and the foundation pit will cause the foundation pit to vibrate during construction, resulting in a reduction in the stability of the support plate and requiring regular maintenance, which is rather troublesome. Content of the Utility Model

[0004] The purpose of the utility model is to provide a deep foundation pit support structure for civil engineering in order to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A deep foundation pit support structure for civil engineering, comprising: a fixed base and a support plate. Four transverse anchor piles are arranged through the four sides around one side of the support plate, and two auxiliary anchor piles are arranged inside the transverse anchor piles.

[0007] The transverse anchor pile includes a first anchor rod. An annular sliding groove is formed on the surface of one side of the first anchor rod. Longitudinal sliding grooves are symmetrically formed inside the first anchor rod. Fixed sliding grooves are formed on the front and rear sides of the rod body of the first anchor rod, and a limiting block is fixedly arranged inside the fixed sliding groove.

[0008] Longitudinal sliding blocks are slidably arranged inside the two longitudinal sliding grooves. A connecting block is fixedly arranged between the opposite sides of the two longitudinal sliding blocks. A second threaded rod is threadedly sleeved inside the connecting block. Toothed plates are symmetrically arranged above and below one side of the connecting block. A rotating handle is fixedly arranged on one side of the second threaded rod. Slide rods are fixedly arranged on the front and rear sides of the rotating handle close to the second threaded rod.

[0009] Furthermore, a first sliding groove is formed in the middle of the top side of the fixed base. The first sliding groove includes a first threaded rod, and a longitudinal clamping block is fixedly arranged on the rod body of one side of the first threaded rod.

[0010] Further, a circular sleeve is fixedly arranged at the front of one side of the long strip-shaped clamping block, and a sliding rotating rod is rotatably sleeved inside the circular sleeve.

[0011] Further, the auxiliary anchor pile includes a second anchor rod, a gear disc is rotatably arranged on the front side of the rod body of the second anchor rod, a fixing ring is rotatably arranged on the outer surface of the gear disc, a limiting rod and a connecting rod are respectively fixedly arranged on both sides of the front side of the fixing ring, and a groove is arranged on the rod body of the second anchor rod.

[0012] Further, one end of the connecting rod is connected to the fixing ring, and the other end is connected to the inner wall of the first anchor rod in the transverse anchor pile. The limiting rod is L-shaped, one end of which is connected to the front side of the fixing ring, and the other end is slidably arranged inside the groove.

[0013] Further, fixing anchor piles penetrate through the front and back of the top side of the fixed base, and a first sliding plate is slidably arranged inside the first chute.

[0014] Further, a second chute is arranged on one side of the support plate, and a second sliding plate is slidably arranged inside the second chute.

[0015] Further, a connecting plate is rotatably arranged between the first sliding plate and the second sliding plate. A rotating groove is arranged on one side of the fixed base. A fixing rod is fixedly arranged between the front and back inside the rotating groove. A plurality of clamping grooves are arranged on the other side of the fixed base, and the clamping grooves are arranged in a circular ring.

[0016] With the above structure, the construction worker rotates the sliding rotating rod to drive the first threaded rod through the long strip-shaped clamping block, so that when the first threaded rod engages with the thread, it drives the first sliding plate to move inside the first chute, and the first sliding plate pulls and changes the position of the second sliding plate through the connecting plate to complete the change of the inclination angle of the support plate. After the inclination angle is determined, the sliding rotating rod is clamped inside the clamping groove to complete the operation of different support angles;

[0017] After the angle is changed, four transverse anchor piles are inserted into the four sides of the support plate to make the support plate itself more stable and improve the support effect. At the same time, by rotating the rotating handle, the second threaded rod on the other side of the rotating handle rotates. The second threaded rod moves the connecting block to one side through the thread, and meshes with the gear disc in the auxiliary anchor pile through the symmetrically arranged toothed plates to make it rotate. When the gear disc rotates, it moves the second anchor rod outward through the internal thread, protruding out of the transverse anchor pile body, so that the auxiliary anchor pile inside the transverse anchor pile bifurcates to both sides of the transverse anchor pile to assist the transverse anchor pile and make the transverse anchor pile fixed more stably.

[0018] In summary, the beneficial effects of the present utility model are as follows: Through the cooperation between the first sliding plate and the second sliding plate in the first sliding groove and the second sliding groove, the angle between the fixed base and the support plate can be adjusted, and two symmetrical auxiliary anchor piles are arranged inside each transverse anchor pile. The auxiliary transverse anchor piles are inserted into the inner side of the foundation pit to improve the stability of the support plate and reduce the frequency of subsequent maintenance after the installation of the support plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope protected by the present utility model.

[0029] See Figures 1-6 As shown, the present utility model provides a deep foundation pit support structure for civil engineering, including: a fixed base 1 and a support plate 6. Four transverse anchor piles 9 are penetrated through the four sides around one side of the support plate 6. Two auxiliary anchor piles 13 are arranged inside the transverse anchor piles 9. Fixed anchor piles 2 are penetrated through the front and rear of the top side of the fixed base 1. A first sliding plate 3 is slidably arranged inside a first chute 4. A second chute 8 is opened on one side of the support plate 6. A second sliding plate 7 is slidably arranged inside the second chute 8. A connecting plate 5 is rotatably arranged between the first sliding plate 3 and the second sliding plate 7. A rotating groove 11 is opened on one side of the fixed base 1. A fixing rod 12 is fixedly arranged between the front and rear inside the rotating groove 11. A plurality of card slots 10 are opened on the other side of the fixed base 1, and the card slots 10 are arranged in a circular ring.

[0030] During use, construction workers can adjust the position of the first sliding plate 3 inside the first chute 4 through the structure in the first chute 4, so that the first sliding plate 3 moves horizontally inside the first chute 4, and pull the second sliding plate 7 inside the second chute 8 through the connecting plate 5 on the top side, so that the second sliding plate 7 moves synchronously with the first sliding plate 3, which is convenient for construction workers to adjust according to foundation pits at different angles. And the support plate 6 itself is made more stable through the transverse anchor piles 9. Two auxiliary anchor piles 13 are arranged inside the transverse anchor piles 9 themselves. When the auxiliary anchor piles 13 slide out from inside the transverse anchor piles 9, the insertion of the transverse anchor piles 9 becomes more stable, improving the support capacity and self-stability of the support plate 6.

[0031] See Figure 5 and Figure 6As shown, the horizontal anchor pile 9 includes a first anchor rod 901. An annular sliding groove 904 is formed on one side surface of the first anchor rod 901. Longitudinal sliding grooves 905 are symmetrically formed inside the first anchor rod 901. Fixed sliding grooves 902 are formed on both the front and rear sides of the rod body of the first anchor rod 901. A limiting block 903 is fixedly arranged inside the fixed sliding groove 902. Longitudinal sliding blocks 906 are slidably arranged inside both longitudinal sliding grooves 905. A connecting block 908 is fixedly arranged between the opposite sides of the two longitudinal sliding blocks 906. A second threaded rod 909 is threadedly sleeved inside the connecting block 908. Tooth plates 907 are symmetrically arranged above and below one side of the connecting block 908. A rotating handle 910 is fixedly arranged on one side of the second threaded rod 909. Slide rods 911 are fixedly arranged on the front and rear sides of the side of the rotating handle 910 close to the second threaded rod 909.

[0032] With the above embodiment, the fixed sliding grooves 902 formed on both the front and rear sides of the first anchor rod 901 can enable the auxiliary anchor pile 13 to slide inside, and at the same time, the position of the auxiliary anchor pile 13 can be limited by the limiting block 903 on one side of the inner wall and inside the fixed sliding groove 902, so that the moving range of the auxiliary anchor pile 13 is limited. The longitudinal sliding grooves 905 formed inside are convenient for the connecting block 908 to drive the two longitudinal sliding blocks 906 on its top and bottom sides to slide inside, limiting the moving range of the connecting block 908, so that the connecting block 908 can only slide horizontally. The sliding of the connecting block 908 is achieved by the construction worker rotating the rotating handle 910. The rotating handle 910 passes through the connecting block 908 through the second threaded rod 909, and the connecting block 908 moves horizontally through threaded engagement. While the connecting block 908 moves horizontally, it contacts the auxiliary anchor pile 13 through the symmetrically arranged rack, pushing the auxiliary anchor pile 13 outward to control the auxiliary anchor pile 13 to cooperate with the horizontal anchor pile 9 for fixation.

[0033] See Figure 3 As shown, a first sliding groove 4 is formed in the middle of the top side of the fixed base 1. The first sliding groove 4 includes a first threaded rod 401. A longitudinal clamping block 402 is fixedly arranged on one side rod body of the first threaded rod 401. A circular sleeve 403 is fixedly arranged in front of one side of the longitudinal clamping block 402. A sliding rotating rod 404 is rotatably sleeved inside the circular sleeve 403.

[0034] With the above technical solution, the construction worker manually rotates the sliding rotating rod 404, causing the sliding rotating rod 404 to drive the first threaded rod 401 to rotate through the long strip block 402. The first threaded rod 401 drives the first sliding plate 3 to move inside the first chute 4 through the thread on its outer surface, and drives the second sliding plate 7 through the connecting plate 5 to adjust the inclination angle of the supporting plate 6. When the appropriate angle is adjusted, the construction worker pushes the sliding rotating rod 404 inward and snaps the sliding rotating rod 404 into the corresponding card slot 10 to complete the fixation after adjusting the inclination angles of the first sliding plate 3 and the supporting plate 6.

[0035] See Figure 5 As shown, the auxiliary anchor pile 13 includes a second anchor rod 1301. A gear disk 1302 is rotatably arranged on the front side of the rod body of the second anchor rod 1301. A fixing ring 1303 is rotatably arranged on the outer surface of the gear disk 1302. On both sides of the front side of the fixing ring 1303, a limiting rod 1304 and a connecting rod 1305 are respectively fixedly arranged. A groove 1306 is formed in the rod body of the second anchor rod 1301. One end of the connecting rod 1305 is connected to the fixing ring 1303, and the other end is connected to the inner wall of the first anchor rod 901 in the transverse anchor pile 9. The limiting rod 1304 is L-shaped, with one end connected to the front side of the fixing ring 1303 and the other end slidably arranged inside the groove 1306.

[0036] During use, the other end of the connecting rod 1305 is connected to the inside of the first anchor rod 901 to support the fixing ring 1303. The gear disk 1302 rotates inside the fixing ring 1303. The outer surface of one side of the gear disk 1302 is a gear and is directly engaged with the toothed plate 907. When the connecting block 908 drives the toothed plate 907 to move, the gear disk 1302 will be rotated by the rack. When the gear disk 1302 rotates, the second anchor rod 1301 will move by the engagement of the thread inside and the thread outside the second anchor rod 1301. At the same time, the limiting rod 1304 is inserted into the groove 1306 formed on one side of the rod body of the second anchor rod 1301, so that the second anchor rod 1301 cannot rotate and can only be driven by the thread to move back and forth to cooperate with the transverse anchor pile 9 to strengthen the supporting effect of the supporting plate 6.

[0037] With the above structure, the construction worker rotates the sliding rotating rod 404 to drive the first threaded rod 401 through the long strip block 402. When the first threaded rod 401 engages with the thread, it drives the first sliding plate 3 to move inside the first chute 4, and the first sliding plate 3 pulls and changes the position of the second sliding plate 7 through the connecting plate 5 to complete the change of the inclination angle of the supporting plate 6. After the inclination angle is determined, snapping the sliding rotating rod 404 into the card slot 10 can complete the operation of different supporting angles;

[0038] After the angle change is completed, insert the four horizontal anchor piles 9 around the support plate 6 to make the support plate 6 itself more stable, improve the support effect. At the same time, by rotating the rotary handle 910, the second threaded rod 909 on the other side of the rotary handle 910 rotates. The second threaded rod 909 makes the connecting block 908 move to one side through the thread, and makes the toothed plate 907 arranged symmetrically engage with the gear disk 1302 in the auxiliary anchor pile 13 to make it rotate. When the gear disk 1302 rotates, it will make the second anchor rod 1301 move outward through the internal thread, protruding out of the body of the horizontal anchor pile 9, so that the auxiliary anchor pile 13 inside the horizontal anchor pile 9 bifurcates to both sides of the horizontal anchor pile 9, assisting the horizontal anchor pile 9 to make the horizontal anchor pile 9 fixed more stably.

[0039] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
