Problems solved by technology

The dry method requires cofferdams and water pumping, which requires a large amount of work; the wet method requires diving operations. Due to the limitation of diving, the same pile can only be constructed by 1 to 2 divers, and the efficiency is low.

Embodiment Construction

[0031] Such as figure 1 with figure 2 As shown, the present invention provides a concrete pile defect underwater wet repair device, comprising a side form 1 that surrounds the concrete pile 8 and a bottom form 2 that seals between the concrete pile 8 and the bottom of the side form 1, said The bottom mold 2 is arranged at the bottom of the side mold 1 . The side form 1 forms a formwork around the concrete pile 8 to be repaired, a certain gap is reserved between the side form 1 and the concrete pile 8, the bottom form 2 seals the bottom gap between the concrete pile 8 and the side form 1, and then the repair material is poured into the side form 1 and the concrete pile 8, after the repairing material is solidified, the repairing device can be disassembled and reused.

[0032] Specifically, the side mold 1 includes a first side mold 11 and a second side mold 12, and the first side mold 11 and the second side mold 12 are made of light and hard materials. The frame 3 for reinf...

Abstract

The invention provides an underwater wet-method repairing device and method for concrete pile defects. The repairing device comprises side molds and bottom molds, wherein the side molds are used for enclosing a concrete pile, and the bottom molds are used for sealing the concrete pile and the bottom parts of the side molds, and the bottom molds are arranged at the bottom parts of the side molds. The underwater wet-method repairing device for the concrete pile defects has the advantages of being convenient to install, capable of being repeatedly used and high in repairing efficiency.

Description

technical field [0001] The invention relates to an underwater wet repairing device and repairing method for concrete pile defects. Background technique [0002] Concrete piles will have defects such as exposed reinforcement, necking, and insufficient protective layer due to construction or environmental erosion. If the bearing capacity of the pile meets the requirements, the damaged part can be repaired by the method of section restoration to restore the durability of the pile and ensure the usability and safety of the structure. For parts with small defects, the repair material can be manually applied directly on the damaged part to achieve the purpose, and for the case of large defect parts, the method of re-pouring repair materials with vertical formwork is used to restore the section. [0003] For the above-water part of the pile, the vertical form casting technology is relatively mature and reliable. For the underwater part of the pile, it is generally divided into dr...
