Hermetic seal process for box body and pile body

Abstract

The invention discloses a sealed and watertight method between a box body and a pile body; the waterproof method is used for sealing and watertightness between the pile body and the box body. The invention is characterized in that: with the method, an annular airbag is arranged in a gap between the box body and the pile body; further an annular airbag groove is made on the pile hole sidewall of the soleplate of the box body; when the annular airbag is placed, the annular airbag is put in the annular airbag groove; the watertight method of the invention is simple in operation, reliable in watertightness and suitable for watertightness under various environmental conditions; in particular the invention adopts the technical proposal, no matter how partial difference between the positions of the pile body and the hole, the airbag can realize the complete watertightness as the own property of the airbag; therefore, underwater construction can be carried out without needing divers, thereby greatly shorting the construction period, improving the quality and safety of the construction, saving the construction cost and avoiding the pollution to a construction water area.

Description

technical field [0001] The invention relates to a method for sealing and water-stopping the gap between a box body and a pile body when a cap is made on a pile body in water, in particular to a method for sealing and water-stopping between a box body and a pile body. Background technique [0002] In the construction of bridges, wharves and power plants, it is often encountered in the construction of piles in water, and the construction of caps on pile bodies. When the caps are prefabricated, some box-like components such as steel hanging boxes and casings need to be installed on the pile bodies. , as the mold of the prefabricated cap or the cofferdam of the prefabricated cap, the reinforced skeleton is poured into the concrete or the bracket formwork inside it. The components of these boxes are very large, ranging from tens of cubic meters in size to tens of thousands of cubic meters in size. One cap needs to be supported by multiple piles. Like the Sutong Bridge, one cap n...

Problems solved by technology

Although this invention has a good water-stop construction effect and solves the deficiencies and defects of the existing construction technology, various defects are also exposed in the actual use process: the technical solution uses a strip-shaped air bag, and it also needs Connecting and retaining with iron wire will inevitably cause poor water-stopping effect and sealing effect at the joint. Several operating holes are opened along the circumference at the appropriate position of the pipe wall of the bored pile. This step increases the workload. It is difficult to operate the airbag through the gap between the catheter and the casing, and it needs to be operated underwater; the end of the belt-shaped airbag is wrapped with sponge, and the upper edge of the airbag is used to withstand the water stop with top pressure steel bars Unreliable; it is difficult to place and position the airbag; especially when the airbag is adjusted to the proper position, it is very difficult to check the airtightness of the airbag; these are all underwater operations

Therefore, the work efficiency is low and the construction period is long
