It is widely used in engineering fields such as construction, highways and railways to improve slope stability and prevent collapse accidents.

[0003] In slope protection, a commonly used support structure is the pile-slab retaining wall, which consists of reinforced concrete piles and retaining slabs. It resists lateral soil pressure by installing retaining slabs between deeply embedded piles, exhibiting good stability and high lateral pressure resistance. However, its construction process is complex, especially the reverse construction method for the concrete retaining slabs between piles, which involves cumbersome construction and difficult formwork reinforcement. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the above-mentioned technology by proposing a precast concrete baffle structure between piles, which aims to solve the above problems.

The plurality of precast concrete slabs are arranged between two cast-in-place piles, and adjacent precast concrete slabs are connected in sequence. A cast-in-place concrete area is left between the side of the precast concrete slab and the corresponding cast-in-place pile. The ends of the multiple sets of anchoring components pass through the cast-in-place concrete area and are anchored into the cast-in-place pile. A cast-in-place slab is formed by casting within the cast-in-place concrete area.

[0006] Preferably, each set of anchoring components includes two reinforcing bars and two connecting bars. One end of the two reinforcing bars is anchored into the cast-in-place pile, and the other end of the two reinforcing bars is connected to the corresponding connecting bars. The other end of the two connecting bars is connected to the reinforcing bars on the precast concrete slab.

[0007] Preferably, the reinforcing bar is welded to the connecting reinforcing bar, and the connecting reinforcing bar is welded to the pre-embedded reinforcing bar of the precast concrete slab.

[0008] Preferably, the lower end of the precast concrete slab is provided with a convex groove, and the upper end of the precast concrete slab is provided with a concave groove, with the adjacent convex grooves and concave grooves cooperating with each other.

[0009] Preferably, the precast concrete slab has a plurality of first embedded steel bars extending from its sides, and the plurality of first embedded steel bars are connected to the corresponding anchoring components.

[0016] Example 1 Reference Figures 1 to 5 This utility model provides a precast concrete retaining structure between piles, including a plurality of precast concrete slabs 1 and multiple sets of anchoring components 2 connected to the left and right sides of each precast concrete slab 1. The precast concrete slabs 1 are arranged vertically between two cast-in-place piles 5, and the distance between each precast concrete slab 1 and the two cast-in-place piles 5 is equal. Adjacent precast concrete slabs 1 are connected sequentially. Multiple precast concrete slabs 1 can be connected vertically according to the slope height to provide support at the slope. A concrete casting area 6 is left between the side of the pile and the corresponding cast-in-place pile 5. The ends of the multiple sets of anchoring components 2 pass through the concrete casting area 6 and are anchored into the cast-in-place pile 5. A cast-in-place slab 7 is formed by pouring concrete in the concrete casting area 6. Concrete can be poured into the precast concrete slab 1. After solidification, a cast-in-place slab 7 is formed that is fixed to the precast concrete slab 1 and the cast-in-place pile 5 respectively. The construction process of the concrete baffle between the piles is simple. The cast-in-place pile 5 is used as the force point to stabilize the concrete baffle between the piles, reduce the difficulty of reinforcement, and support the soil layer 14 behind the concrete baffle between the piles.

[0017] Each set of anchoring components 2 includes two reinforcing bars 3 and two connecting reinforcing bars 4. One end of the two reinforcing bars 3 is anchored into the cast-in-place pile 5, and the other end of the two reinforcing bars 3 is connected to the corresponding connecting reinforcing bars 4. The other end of the two connecting reinforcing bars 4 is connected to the reinforcing bars on the precast concrete slab 1. The reinforcing bars 3 are welded to the connecting reinforcing bars 4, and the connecting reinforcing bars 4 are welded to the pre-embedded reinforcing bars of the precast concrete slab 1 to increase the fixing strength.

[0018] The lower end of the precast concrete slab 1 is provided with a convex groove 8, and the upper end of the precast concrete slab 1 is provided with a concave groove 9. The adjacent convex grooves 8 and concave grooves 9 cooperate with each other. When multiple precast concrete slabs 1 are connected in sequence, the convex groove 8 of the upper precast concrete slab 1 is embedded in the concave groove 9 of the lower precast concrete slab 1. The connection method of the precast concrete slabs 1 is simple and convenient.

[0019] The precast concrete slab 1 has a plurality of first pre-embedded steel bars 10 extending out of its side. The plurality of first pre-embedded steel bars 10 are connected to the corresponding anchoring components 2, which facilitates the connection between the precast concrete slab 1 and the anchoring components 2.

[0020] The precast concrete slab 1 is provided with a drain outlet 11, which serves to drain water.

[0021] The precast concrete slab 1 is provided with several grouting holes 15. After the precast concrete slab 7 is formed by pouring concrete into the cast-in-place area 6, the gap between the precast concrete slab 1 and the soil layer 14 is filled through the grouting holes 15.

[0022] In use, several cast-in-place piles 5 can be constructed at the slope. A precast concrete slab 1 is fixedly installed at the middle position between two adjacent cast-in-place piles 5. The first pre-embedded steel bar 10 extending from the side of the precast concrete slab 1 is welded to the corresponding anchoring component 2. The end of the anchoring component 2 passes through the cast-in-place concrete area 6 and is anchored into the cast-in-place pile 5. According to the slope height, multiple precast concrete slabs 1 are installed vertically from bottom to top, and concrete is poured into the cast-in-place piles 5 and the cast-in-place concrete area 6. After solidification, a cast-in-place slab 7 is formed that is fixed to the precast concrete slab 1 and the cast-in-place piles 5, thus forming a concrete baffle. With the cast-in-place piles 5 as the force point, the concrete baffle between the piles is stabilized, which plays a supporting role at the slope. It has the characteristics of simple construction process and low reinforcement difficulty.

[0023] Example 2 See Figures 4 to 5 The difference between this embodiment and embodiment 1 is that: a number of second pre-embedded steel bars 12 extending out of the bottom of the precast concrete slab 1 are pre-embedded in the slab 1 (i.e., a number of second pre-embedded steel bars 12 protrude out of the convex groove 8), and a number of slots 13 are provided at the bottom of the concave groove 9. The second pre-embedded steel bars 12 correspond to the slots 13, and the free end of the second pre-embedded steel bars 12 is inserted into the slots 13.

[0024] When multiple precast concrete slabs 1 are connected sequentially from bottom to top, the free end of the second embedded steel bar 12 is inserted into the slot 13 to improve the stability of the connection between two adjacent precast concrete slabs 1.
