Description

Technical Field

[0001] This utility model relates to a diagonal bracing reinforcement device for the construction of anti-sliding pile slab walls in foundation pits, belonging to the field of building foundation pit excavation and support technology. Background Technology

[0002] Anti-slide pile support is a common method for supporting foundation pit slopes, and anti-slide piles are often used in conjunction with cast-in-place pile-slab walls to achieve better support effects. Currently, the common construction process for anti-slide pile-slab walls involves excavating the entire foundation pit slope after the anti-slide piles are poured, and then constructing the pile-slab wall layer by layer from bottom to top. This method does not conform to the construction principle of supporting the foundation pit before excavation and layered support from top to bottom, and carries the risk of rockfall or even collapse of the foundation pit slope. Precast pile-slab wall assembly also faces the problem of needing to be constructed from bottom to top. If foundation pit support is to be implemented from top to bottom, existing processes can only use shotcrete between piles. Shotcrete pile-slab walls have limited support capacity, are prone to loosening, and pose a threat to the safety of construction personnel and equipment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a diagonal bracing reinforcement device for the construction of foundation pit anti-sliding pile slab wall, so as to solve the technical problems existing in the prior art.

[0004] The technical solution adopted by this utility model is as follows: a diagonal bracing reinforcement device for the construction of anti-sliding pile slab wall in foundation pit, comprising main ribs, secondary ribs, supporting diagonal rods and anti-sliding plates. The main ribs are arranged horizontally, and two or more main ribs are arranged in parallel. The secondary ribs are perpendicular to the main ribs and form an acute angle with the vertical direction, and two or more secondary ribs are arranged in parallel. The main ribs and the secondary ribs are installed on the outer surface of the wall formwork. The anti-sliding plates are installed on the excavation surface. One end of the supporting diagonal rod is installed on the main rib, and the other end is installed on the anti-sliding plate. The number of supporting diagonal rods is set to two or more.

[0005] Preferably, the anti-slip plate includes a rectangular base plate arranged in a horizontal direction, the upper end of the base plate is fixed with a grid for limiting one end of the supporting diagonal rod, and reinforcement holes are provided at the four corners of the base plate.

[0006] Preferably, each of the main ribs is formed by fixing two round steel bars together.

[0007] Preferably, the secondary rib is a rectangular steel pipe.

[0008] Preferably, the supporting diagonal rod is a steel bar.

[0009] Preferably, the length of the supporting diagonal rod is set to two or more, and each corresponds to a main rib of different heights.

[0010] Preferably, the grille includes a first upright plate vertically fixed to the upper end of the base plate, and two or more second upright plates are evenly fixed between one side of the first upright plate and the base plate, with a U-shaped space formed between two adjacent second upright plates to limit the support diagonal rod.

[0011] Preferably, the base plate, the first upright plate, and the second upright plate are all steel plates.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, the use of this utility model not only ensures the stability of the formwork but also facilitates construction operations. The anti-slip plate used in formwork construction increases the contact area between the diagonal braces and the ground, improving the overall stability of the construction site, especially under soft soil conditions. This effectively prevents the diagonal braces from slipping, ensuring the safety of construction personnel and equipment. Attached Figure Description

[0017] Example 1:

[0018] A diagonal bracing reinforcement device for the construction of anti-sliding pile-slab walls in foundation pits, such as... Figures 1-2As shown, the wall formwork includes main ribs 3, secondary ribs 4, supporting diagonal braces 2, and anti-slip plates 1. The main ribs 3 are arranged horizontally, with five parallel main ribs. Each main rib 3 is formed by two round steel bars fixed together. The secondary ribs 4 are fixed perpendicularly to the main ribs 3 and form an acute angle with the vertical direction. The inclination angle of the secondary ribs 4 is determined according to the actual site conditions. The secondary ribs 4 are rectangular steel pipes, and 18 parallel secondary ribs 4 are installed. The main ribs 3 and secondary ribs 4 are installed on the outer surface of the wall formwork. The supporting diagonal braces 2 are steel bars, with one end installed on the main rib 3 and the other end... The anti-slip plate 1 is installed on the excavation surface. The anti-slip plate 1 includes a rectangular base plate 11 arranged horizontally. A grid is fixed to the upper end of the base plate 11 to limit one end of the supporting diagonal rod 2. The grid includes a first vertical plate fixed vertically to the upper end of the base plate 11. Sixteen second vertical plates are evenly spaced between one side of the first vertical plate and the base plate 11, forming a U-shaped space between adjacent second vertical plates to limit the supporting diagonal rod 2. In this embodiment, the base plate 11, the first vertical plate, and the second vertical plates are all steel plates. The number of supporting diagonal rods 2 is set to nine, and the length of the supporting diagonal rods 2 is set to two or more types, each corresponding to a main rib 3 of different heights.
