Construction method of pile body underwater cutting

Abstract

The invention discloses a construction method of pile body underwater cutting, wherein the method comprises the following steps: underwater cleaning, embedding bolt on a base plate of a dock port, drilling enclosure wall of the pile body, underwater cutting, and cleaning out dock gate; a chain saw cutting machine is used to act on a cast-in-place pile and a three-shaft stirring body which are to be disassembled to directly destroy the combination among molecules when the materials (metal, concrete and the like) are located at a solid state so as to form a cut, and then the cut-off materials are lifted away. The construction method has the beneficial effects of possible mechanization, easy operation, smooth cut, being suitable for the underwater cutting of materials in irregular shape and materials in large area and large volume, high security, high construction speed, environment protecting, no vibration, no noise, no dust and no pollution to water area.

Description

technical field [0001] The invention relates to a construction method for underwater cutting of a pile body, which is suitable for underwater demolition of the retaining wall of a dock mouth. Background technique [0002] The existing underwater cutting adopts forming blasting cutting, which has two disadvantages. One is that the cut pile body is in a free state, and it is difficult to control the direction of its dumping. If it falls to the inside of the dock mouth, it will damage the dock mouth The structure was damaged; secondly, there was a certain amount of vibration from the blasting. The water-stop system under the bottom plate at the front edge of the dock is water-stopped with high-pressure jet-spray piles. [0003] Therefore, in contrast, the construction of this method is safe and reliable. Contents of the invention [0004] In order to overcome the above-mentioned shortcoming, the object of the present invention is to provide a kind of construction method of p...
