TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of foundation pit construction, and in particular, to a bridge pile foundation exposure protection and inter-pile soil consolidation device and a construction method. BACKGROUND

[0002] When constructing an underground building beneath a bridge, a foundation pit is excavated at a location with bridge pile foundations. During this process, there is inter-pile soil between the bridge pile foundations. In conventional foundation pit construction, the inter-pile soil needs to be removed, typically through staged excavation using an excavation device or manual clearing with scaffolding.

[0003] Regarding the above related art, the inventors found that clearing the inter-pile soil is time-consuming and labor-intensive. In response of small space between the bridge pile foundations, it is difficult for the excavation device to operate. Manual clearing not only involves risks associated with working at height, but also has low clearing efficiency and significant time consumption. SUMMARY

[0004] One objective of the present disclosure is to provide a bridge pile foundation exposure protection and inter-pile soil consolidation device, alleviating the problem of low efficiency in clearing inter-pile soil.

[0005] The bridge pile foundation exposure protection and inter-pile soil consolidation device provided by the present disclosure employs the following technical solutions:

[0006] The bridge pile foundation exposure protection and inter-pile soil consolidation device includes a foundation pit, multiple bridge pile foundations, and inter-pile soil located between the bridge pile foundations, where protective meshes are disposed on outer sides of the inter-pile soil; the protective meshes are fixed to outer side walls of the bridge pile foundations; first fixed plates and second fixed plates are disposed on outer sides of the bridge pile foundations; one first fixed plate and one second fixed plate form one group; multiple groups of first fixed plates and second fixed plates are disposed on the outer sides of the bridge pile foundations in a vertical direction; the first fixed plates and the second fixed plates are fixed to the bridge pile foundations through first fixing screws; the first fixed plates and the second fixed plates are connected and fixed through second fixing screws; and a connecting mechanism is disposed between two groups of first fixed plates and second fixed plates.

[0007] Through the above technical solutions, when the foundation pit is constructed in stages, the protective meshes are first fixed between the bridge pile foundations throughout the construction stages, and the protective meshes preliminarily surround the inter-pile soil, preventing the inter-pile soil from falling during construction to cause accidents. After the protective meshes are mounted, the first fixed plates and the second fixed plates are disposed on the outer sides of the bridge pile foundations, one first fixed plate and one second fixed plate form one group, and multiple groups of first fixed plates and second fixed plates are mounted in the vertical direction throughout the construction stages of the foundation pit, such that the first fixed plates and the second fixed plates completely surround the bridge pile foundations. The first fixed plates and the second fixed plates are fixed to the bridge pile foundations through the first fixing screws, and the first fixed plates and the second fixed plates are connected and fixed through the second fixing screws. Spaces between the first fixed plates, the second fixed plates, and the bridge pile foundations are filled with concrete, the concrete completely seals the inter-pile soil in the bridge pile foundations, thereby completing the construction of the foundation pit without clearing the inter-pile soil. The connecting mechanism is disposed between two adjacent groups of first fixed plates and second fixed plates. When the first fixed plates and the second fixed plates are mounted, the connecting mechanism assists in positioning the first fixed plates and the second fixed plates, thus improving the mounting precision and mounting efficiency of the first fixed plates and the second fixed plates.

[0008] Preferably, the connecting mechanism includes a connecting rod and a connecting hook; fixed grooves are respectively formed in outer side walls of the first fixed plate and the second fixed plate; the connecting rod is disposed in the fixed groove; the connecting hook is rotatably connected to the connecting rod; positioning slots are respectively formed in the outer side walls of the first fixed plate and the second fixed plate; and the connecting hook is insertable into the positioning slot.

[0009] Through the above technical solutions, the connecting mechanism includes the connecting rod and the connecting hook, the fixed groove is formed in the first fixed plate and the second fixed plate, the connecting rod is disposed in the fixed groove, and the connecting hook is rotatably connected to the connecting rod, such that the connecting hook may rotate. The positioning slot for the connecting hook to be inserted in is formed in the first fixed plate and the second fixed plate. When a next group of first fixed plate and second fixed plate is mounted, the connecting hook is rotated and inserted into the positioning slot, and the next group of first fixed plate and second fixed plate is temporarily fixed on the connecting hook, bringing convenience for later mounting and fixation. That is, the connecting mechanism can perform preliminary fixation and positioning when the next group of first fixed plate and second fixed plate is mounted, thus improving the mounting efficiency.

[0010] Preferably, a limiting slot is formed in an inner side wall of the positioning slot, and a soft rubber pad is disposed on an inner side wall of the limiting slot.

[0011] Through the above technical solutions, the limiting slot is formed in the positioning slot. When being inserted into the positioning slot, the connecting hook can also be inserted into a lower slot, thereby improving the connecting stability. The soft rubber pad is circumferentially mounted on the inner side wall of the limiting slot, and the soft rubber pad increases the frictional force between the connecting hook and the limiting slot, making the connecting hook fixed more stably.

[0012] Preferably, a first magnetic member magnetically attracted with the connecting hook is disposed at a bottom of the limiting slot.

[0013] Through the above technical solution, the connecting hook inserted into the limiting slot is attracted through the magnetic force of the first magnetic member, thereby improving the mounting efficiency of the connecting hook, and improving the mounting stability of the connecting hook.

[0015] Through the above technical solutions, the connecting baffle is disposed on a side of a group of first fixed plate and second fixed plate attached to an adjacent group of first fixed plate and second fixed plate. When being mounted, a next group of first fixed plate and second fixed plate is inserted along the connecting baffle and is attached to a previous group of first fixed plate and second fixed plate, and the connecting baffle may cover a junction of two groups of first fixed plates and second fixed plates at this time. After the concrete is filled, the connecting baffle may prevent the concrete from leaking from the junction.

The soft sealing strip is closely attached to the junction of two groups of first fixed plates and second fixed plates, further improving the sealing effect of the connecting baffle.

[0018] Preferably, a placement slot is formed in a side of the connecting baffle attached to the first fixed plate and the second fixed plate, and a second magnetic member is disposed in the placement slot.

[0019] Through the above technical solutions, the placement slot is formed in the side of the connecting baffle attached to the first fixed plate and the second fixed plate, and the second magnetic member is mounted in the placement slot. The first fixed plate and the second fixed plate are attracted through the magnetic force of the second magnetic member, such that the first fixed plate and the second fixed plate are mounted more stably, and the mounting efficiency of the first fixed plate and the second fixed plate can also be improved.

[0020] Preferably, outer side walls of one group of first fixed plate and second fixed plate close to a bottom of the foundation pit are respectively provided with support rods.

The bearing capability of the first fixed plate and the second fixed plate is improved through the support rods, avoiding the failure of the first fixed plate and the second fixed plate due to poor bearing capability.
