Embodiment

[0028] This embodiment provides a construction method of a cofferdam water stop method, and its specific construction steps are described below.

[0029] Among them, the steel pipe pile cofferdam construction method includes the steel pipe pile cofferdam, and the steel pipe pile cofferdam includes a steel casing, multi-layer corbels, multiple support beams, multiple inner support ring beams and multiple inner support beams, This construction method comprises the following steps:

[0030] Step S1, arranging the steel pipe pile cofferdam, and performing preparatory work on the steel pipe pile cofferdam;

[0031] Step S2, cutting the steel casing for the first time;

[0032] Step S3, installing multi-layer corbels on the outer ring of the steel casing, setting support beams on the corbels, and installing multi-layer connected inner support ring beams and inner support beams on the support beams;

[0033] Step S4, inserting and driving steel pipe pile cofferdams sequentially fro...

Abstract

The invention provides a steel pipe pile cofferdam construction method and a cofferdam water stopping method and belongs to the technical field of building construction. Steel pipe pile cofferdams areincluded and each comprises a steel pile casing, a plurality of layers of brackets, a plurality of supporting beams, a plurality of inner supporting ring beams and a plurality of inner supporting beams. The construction method at least comprises the following steps that S1, the steel pipe pile cofferdams are arranged, and first-phase preparation is carried out on the steel pipe pile cofferdams; S2, first cutting is carried out on the steel pipe piles; S3, the multiple layers of brackets are arranged on the outer ring of the corresponding steel pile casings, the brackets are provided with thesupporting beams, and the supporting beams are provided with the multiple layers of the inner supporting ring beams and the inner supporting beams which are connected; and S4, the steel pipe pile cofferdams are sequentially beaten from the upstream to the downstream. The cofferdam water stopping method adopts the steel pipe pile cofferdam construction method, and the seepage prevention effect of the steel pipe pile cofferdams is good.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a steel pipe pile cofferdam and a water-stopping method for the cofferdam. Background technique [0002] The main function of the cofferdam is generally as a water-retaining and soil-retaining structure for the construction of the bridge cap. The loads it bears include water flow impact force, water head pressure, and earth pressure, etc., to provide space for the construction cap. However, the existing cofferdam basically adopts the structure of steel pipe insertion and connection, which is not tight enough, and there are some parts that can retain soil but are easy to leak water, which makes the construction cap not safe and reliable, and affects the construction of the bridge. Contents of the invention [0003] The invention provides a steel pipe pile cofferdam construction method and a cofferdam water-stopping method, aiming at solving...
