Description

Technical Field

[0001] The utility model belongs to the technical field of concrete detection, in particular to a deep foundation pit steel sheet pile supporting structure. Background Art

[0002] Deep foundation pit refers to an engineering project with an excavation depth of more than 5 meters (including 5 meters), or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. Steel sheet piles are often used in deep foundation pits. At the same time, steel sheet piles are a kind of steel structure with a linkage device on the edge, and this linkage device can be freely combined to form a continuous and tight retaining wall or water retaining wall. Therefore, in order to improve the stability of steel sheet piles, corresponding support devices will be used, but they still have the following disadvantages in actual use:

[0003] 1. When using the support structure to support the steel sheet piles, the support structure is prone to instability due to the lack of the ability to improve the support of the steel sheet piles, causing the support structure to tilt, thereby causing the position of the steel sheet piles to deviate;

[0004] 2. When using the supporting structure, since there is no adjustment for the supporting points of the steel sheet piles, it is impossible to adjust according to the height of the steel sheet piles, and the steel sheet piles will be too high, causing the supporting structure to fail to achieve the corresponding working effect. Utility Model Content

[0005] The purpose of the utility model is to provide a deep foundation pit steel sheet pile support structure, which limits the support plate by reinforcing rods so that the distance between the two support plates cannot deviate, thereby ensuring the position of the steel sheet piles. At the same time, the distance adjustment and angle rotation between the tilting rod and the progressive screw rod solve the problems of not being able to improve the support capacity of the steel sheet piles and not being able to adjust according to the height of the steel sheet piles.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a deep foundation pit steel sheet pile supporting structure, comprising two support plates which are symmetrically arranged on the left and right, two reinforcing rods which are symmetrically arranged on the front and back are arranged on the upper part between the two support plates, clamping blocks are fixed on the left and right ends of the reinforcing rods, diagonal blocks are fixed at the positions of the two support plates corresponding to the reinforcing rods, the clamping blocks are respectively arranged on the inner sides of the adjacent diagonal blocks, inclined rods are arranged on the left and right parts of the upper sides of the reinforcing rods, progressive screw holes are opened on the opposite ends of the inclined rods which are consistent in the left and right directions, progressive screws are spirally arranged inside the progressive screw holes, and abutment plates are arranged on the opposite ends of the two inclined rods which are consistent in the left and right directions.

[0008] Furthermore, a plurality of strip blocks evenly distributed linearly from front to back are fixed to the lower parts of the opposite side walls of the two support plates.

[0009] Furthermore, the front and rear side walls of the diagonal block are both provided with inclined grooves, and the front and rear side surfaces of the clamping block are both fixed with clamping rods located inside the inclined grooves.

[0010] Furthermore, U-shaped blocks are fixed at positions of the circumferential sides of the middle portion of the reinforcing rod corresponding to the positions of the progressive screw rods, and rotating rods are fixed between the inner side surfaces of the U-shaped blocks.

[0011] Furthermore, a rotating ring block is fixed to the end of the progressive screw rod passing through the progressive screw hole, and the rotating ring block is rotatably sleeved on the circumferential side of the rotating rod.

[0012] Furthermore, an I-shaped block is fixed to the middle position of the side of the abutment plate relative to the tilting rod, and an annular block rotatably sleeved inside the I-shaped block is fixed to the end of the tilting rod opposite to the progressive screw.

[0013] The utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, the reinforcing rod is arranged at a position between two support plates, so that the clamping blocks at both ends of the reinforcing rod are arranged inside the diagonal blocks, and then the clamping blocks make the clamping rod directly inserted into the inclined groove, so that the reinforcing rod is limited at a position between the two support plates, and the reinforcing rod limits the support plates at both ends, so that the support plates can be stably connected to the steel sheet piles, so that the support plates can stably support the steel sheet piles and improve the stability of the support.

[0015] 2. When the utility model is in use, when the steel sheet pile is too high, the progressive screw can be rotated and the tilting rod can be rotated, thereby adjusting the length between the tilting rod and the progressive screw, and then the abutment plate at the end of the tilting rod can be abutted against the steel sheet pile, so that the abutment plate can improve the stability of the steel sheet pile and realize the adjustment of the support point according to the height of the steel sheet pile.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 As shown, the utility model is a deep foundation pit steel sheet pile supporting structure, comprising two support plates 1 which are symmetrically arranged on the left and right, two reinforcing rods 2 which are symmetrically arranged front and back are arranged on the upper part between the two support plates 1, and clamping blocks 201 are fixed on the left and right ends of the reinforcing rods 2, and diagonal blocks 102 are fixed at the positions of the two support plates 1 corresponding to the reinforcing rods 2, and the clamping blocks 201 are respectively arranged on the inner sides of the adjacent diagonal blocks 102, and inclined rods 3 are arranged on the left and right parts of the upper sides of the reinforcing rods 2, and progressive screw holes 301 are opened at the opposite ends of the inclined rods 3 in the same left and right directions, and progressive screws 303 are spirally arranged inside the progressive screw holes 301, and the progressive screws 303 are rotated inside the progressive screw holes 301 to adjust the distance between the inclined rods 3 and the progressive screws 303, and abutment plates 305 are arranged at the opposite ends of the two inclined rods 3 in the same left and right directions.

[0025] Among them Figure 1-4 As shown, a plurality of strip blocks 101 are fixed to the lower parts of the opposite side walls of the two support plates 1 and are evenly distributed linearly from front to back, and the front and rear side walls of the diagonal blocks 102 are both provided with inclined grooves 103, and the front and rear side surfaces of the block 201 are both fixed with a clamping rod 202 located inside the inclined groove 103. Since the clamping rod 202 is inside the inclined groove 103, when the distance between the two support plates 1 cannot be adjusted, the clamping rod 202 cannot move inside the inclined groove 103, and the reinforcing rod 2 is limited to the position between the two support plates 1, thereby preventing the reinforcing rod 2 from being moved. An I-shaped block 306 is fixed to the middle position of the side of the connecting plate 305 relative to the tilting rod 3, and an annular block 302 rotatably sleeved inside the I-shaped block 306 is fixed to the end of the tilting rod 3 opposite to the progressive screw 303. When it is necessary to ensure that the abutment plate 305 is in a vertical state, the abutment plate 305 can be rotated, thereby the abutment plate 305 will drive the I-shaped block 306 to rotate at the position of the annular block 302, so as to achieve angle adjustment of the abutment plate 305 and ensure that the abutment plate 305 can stably abut against the steel sheet pile.

[0026] Among them Figure 2 ,3 As shown, U-shaped blocks 203 are fixed at the positions of the progressive screws 303 corresponding to the circumferential sides of the middle of the reinforcing rod 2, and rotating rods 204 are fixed between the inner sides of the U-shaped blocks 203. The ends of the progressive screws 303 passing through the progressive screw holes 301 are fixed with rotating ring blocks 304, and the rotating ring blocks 304 are rotatably sleeved on the circumferential sides of the rotating rods 204. In order to be able to adjust the support treatment of different positions of the steel sheet piles, the progressive screws 303 can be rotated up and down, whereby the progressive screws 303 will drive the rotating ring blocks 304 to move around the rotating rods 204 as the axis, so that the angle between the progressive screws 303 and the reinforcing rods 2 can be adjusted, thereby adjusting the angle of the tilting rods 3, and thereby adjusting the height of the abutment plates 305.

[0027] A specific application of this embodiment is: through the use of the above-mentioned structure, the support plate 1 is placed inside the steel sheet pile, and the strip block 101 at the lower part of the support plate 1 is located below the steel sheet pile, so that the strip block 101 supports the bottom of the steel sheet pile, and the side of the support plate 1 is connected to the steel sheet pile, so that the support plate 1 supports the steel sheet pile, and the reinforcing rod 2 is set between the two support plates 1, so that the blocks 201 at both ends of the reinforcing rod 2 are set inside the diagonal block 102, and the blocks 201 make the clamping rod 202 directly plugged into the inclined In the groove 103, the reinforcing rod 2 is limited in the position between the two support plates 1, and the reinforcing rod 2 limits the support plates 1 at both ends, so that the support plates 1 can be stably connected to the steel sheet piles, and the support plates 1 can stably support the steel sheet piles. At the same time, when the steel sheet piles are too high, the progressive screw 303 can be rotated and the tilting rod 3 can be rotated, so that the length between the tilting rod 3 and the progressive screw 303 can be adjusted, and then the abutment plate 305 at the end of the tilting rod 3 can be abutted against the steel sheet pile, so that the abutment plate 305 can improve the stability of the steel sheet pile.
