Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to a precast concrete square pile foundation reinforcement structure. Background Technology

[0002] In infrastructure construction fields such as building engineering, roads and bridges, and industrial plants, precast concrete square piles are widely used in foundation treatment due to their advantages such as high bearing capacity, convenient construction, and controllable cost. They are especially suitable for geological scenarios with insufficient bearing capacity, such as soft soil foundations and backfilled soil foundations. As the load-bearing foundation of the entire building structure, the stability of the foundation directly determines the safe service life of the superstructure. The core of the reinforcement effect of precast concrete square pile foundations lies in distributing the force on the square piles through the supporting structure and inhibiting foundation settlement and lateral slippage. Therefore, a reliable reinforcement system needs to be designed to improve the overall bearing capacity and deformation resistance of the foundation.

[0003] Currently, in the construction of precast concrete square pile foundations, there is a common phenomenon of "emphasizing the placement of square piles while neglecting reinforcement and support." Most projects rely solely on the embedment capacity of the square piles themselves in the soil for bearing capacity, without setting up dedicated precast supports or reinforcement structures. This design results in the square piles lacking lateral or longitudinal constraints and support during actual use, making them prone to instability when faced with changes in superstructure loads, uneven geological settlement, and lateral earth pressure.

[0006] Furthermore, the pre-assembled bracket has an inner through groove, which is trapezoidal in shape. The support rod passes through the inner through groove and is connected to the pre-assembled bracket.

[0007] Furthermore, the inner through groove is provided with a detachable inner insert block, which is arranged in a triangular structure.

[0008] Furthermore, the inner channel outlet is provided with multiple auxiliary disks, which are equidistantly distributed among each other.

[0023] This application provides a precast concrete square pile foundation reinforcement structure. This structure, through the cooperation of pre-assembled supports and a supporting frame, fills the technical gap of lacking dedicated support reinforcement, effectively improving the overall stability of the foundation and solving the problem of insufficient stability caused by relying solely on the embedment force of the square piles themselves. The following provides a detailed description of this precast concrete square pile foundation reinforcement structure. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of embodiments.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] A precast concrete square pile foundation reinforcement structure includes: a support frame 100, which is composed of multiple support rods 110, with two adjacent support rods 110 connected to form a pair, and multiple pairs of support rods 110 forming a grid-like hierarchical structure; and a pre-installed bracket 200, which is connected to the end of the support rods 110 and is used to pre-install the support rods 110 on the inner wall of the pile foundation hole to fix the support rods 110 to support the square pile foundation. First, pre-set pile foundation holes are made in the foundation, and the pre-installed bracket 200 is fixed to the inner wall of the hole. Then, a single support rod 110 is inserted into the inner through groove 210 of the pre-installed bracket 200 to complete the initial connection between the support rod 110 and the pre-installed bracket 200. Next, two adjacent support rods 110 are overlapped to form a pair, and then multiple pairs of support rods 110 are cross-assembled to finally form a multi-layer grid-shaped hierarchical support frame 100. The square pile foundation is reinforced through the synergistic effect of the support frame 100 and the pre-installed bracket 200.

[0026] The support rod 110 has an insertion hole 140, and a positioning rod 150 passes through the insertion hole 140. The insertion hole 140 is pre-set during the processing stage of the support rod 110. During construction, the pre-installed bracket 200 is first fixed to the inner wall of the hole, and then the support rod 110 is inserted into the through groove 210 inside the pre-installed bracket 200. After the adjacent support rods 110 are overlapped to form a pair, the positioning rod 150 is inserted into the corresponding insertion hole 140 of the pair of support rods 110. The positioning rod 150 is used to lock the relative displacement between the support rods 110.

[0027] Among them, two adjacent support rods 110 are respectively provided with overlapping strips 120 and overlapping grooves 130, and the two support rods 110 are connected by interlocking the overlapping strips 120 and overlapping grooves 130. First, fix the pre-installed bracket 200 to the inner wall of the pile foundation hole, and then insert the two support rods 110 to be paired into the inner through grooves 210 of the corresponding pre-installed brackets 200 respectively; then align the overlapping strip 120 on one of the support rods 110 with the overlapping groove 130 of the other rod, and complete the pairing and fixing of the two support rods 110 by plugging them in. The positioning rod 150 can be used for further reinforcement, and then multiple pairs of support rods can be cross-assembled.

[0028] The pre-installed bracket 200 has an inner through groove 210, which is trapezoidal in shape. The support rod 110 passes through the inner through groove 210 and is connected to the pre-installed bracket 200. The trapezoidal inner through groove 210 is made during the fabrication of the pre-installed bracket 200. During construction, the pre-installed bracket 200 is first fixed to the inner wall of the pile foundation hole, and then the end of the support rod 110 is inserted along the large diameter end of the trapezoidal inner through groove 210 until it penetrates the entire inner through groove 210. By utilizing the fit between the trapezoidal groove wall and the support rod 110, a tight connection between the support rod 110 and the pre-installed bracket 200 is achieved, laying the foundation for the subsequent overlapping of the support rods 110.

[0029] The inner through groove 210 is provided with a detachable inner insert block 230. The inner insert block 230 is triangular in shape. First, the pre-installed bracket 200 is fixed to the inner wall of the hole, and then the support rod 110 is inserted through the inner through groove 210. According to the diameter of the support rod 110, a suitable triangular inner insert block 230 is selected and inserted into the gap between the inner through groove 210 and the support rod 110. The support rod 110 is fixed by wedging.

[0030] Multiple auxiliary discs 211 are provided at the outlet of the inner through groove 210. The multiple auxiliary discs 211 are equidistantly distributed among each other. Multiple auxiliary discs 211 are equidistantly installed at the outlet of the inner through groove 210 of the pre-installed bracket 200. The outer wall of the support rod 110 contacts the auxiliary discs 211. The support rod 110 is guided to move along the inner through groove 210 by sliding on the surface of the auxiliary discs 211 until the assembly of the support rod 110 and the pre-installed bracket 200 is completed, which facilitates subsequent overlapping and pairing.

[0031] The pre-installed bracket 200 has multiple insertion strips 220 at both the top and bottom. The insertion strips 220 have sharp tips. Multiple insertion strips 220 with sharp tips are integrally formed at the top and bottom of the pre-installed bracket 200. During construction, the pre-installed bracket 200 is first placed into the pile foundation hole. The sharp insertion strips 220 are inserted into the soil or rock inside the hole by pressing or impacting the pre-installed bracket 200 with external force, thus fixing the pre-installed bracket 200. Then, the support rod 110 is inserted into the through groove 210 inside the pre-installed bracket for overlapping assembly.
