Problems solved by technology

[0002] In the foundation construction of large bridge caissons, several dredgers often share a set of water and gas supply systems, and all dredges on the platform are equipped with multiple sets of water and gas supply systems. In the case of instability and thus affecting the water and gas supply, it is impossible to guarantee the normal operation of the dredging equipment where the specific caisson head is located
Especially for large-scale caisson projects with a lot of equipment and large mud suction, the water supply and gas supply requirements are high, and failures will seriously affect work efficiency and even delay project progress

Embodiment 1

[0043] Such as figure 1 As shown, in this embodiment, a centralized water supply and gas supply system for large-scale caisson suction mud sinking construction is specifically provided, aiming at ensuring the stability of the water supply and gas supply system and the smooth progress of the caisson sinking construction site. The gas system includes: caisson platform 1, water supply and gas supply pipe group, and water and gas supply assembly. The specific design is as follows:

[0044] ①Water supply and air supply pipe group

[0045] Such as figure 2 As shown, in this embodiment, the caisson platform 1 is divided into two regions, and the two regions are respectively provided with water supply and gas supply pipe groups, so as to realize that each of the water supply and gas supply pipe groups is respectively arranged on the division of the caisson platform 1 in different regions.

[0046] The water supply and gas supply pipe group includes a water supply main pipe 4 and a g...

Embodiment 2

[0073] On the basis of the centralized water supply and gas supply system for large caisson suction mud sinking construction provided in the above-mentioned embodiment 1, a centralized water supply system for large caisson suction mud sinking construction is specifically provided in this embodiment. gas method, which includes:

[0074] S1: The caisson platform 1 is divided into two areas, and the nozzles of the water supply and gas supply pipe groups in the two areas are respectively arranged at the opposite corners of the caisson platform 1 .

[0075] S2: The nozzles of each water supply and air supply pipe group are respectively connected to the corresponding water supply and air supply assembly, and the water supply and air supply assembly is turned on for water and air supply; The assembly supplies water and air.

[0076] S3: After the installation of the water supply and air supply assembly on the multifunctional ship 2 is completed, the high-pressure water and high-pres...

Abstract

The invention discloses a centralized water supply and gas supply system for mud suction sinking construction of a large open caisson, and belongs to the technical field of open caisson construction.The centralized water supply and gas supply system comprises at least two water supply and gas supply pipe sets and water and gas supply assemblies, wherein the water supply and gas supply pipe sets are located in different areas divided by an open caisson platform, the water and gas supply assemblies communicate with the water and gas supply pipe sets respectively, when different areas of the open caisson platform are independent of one another, water and gas are supplied independently through the water and gas supply assemblies, and when different areas of the open caisson platform communicate with one another, water and gas are supplied in a centralized mode through the same water and gas supply assembly, so that the stability of the water and gas supply system is guaranteed, and smoothsinking construction of the open caisson is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of caisson construction, and in particular relates to a centralized water and gas supply system and method for large-scale caisson suction mud sinking construction. Background technique [0002] In the foundation construction of large bridge caissons, several dredgers often share a set of water and gas supply systems, and all dredges on the platform are equipped with multiple sets of water and gas supply systems. In the case of instability and thus affecting the water and gas supply, it is impossible to guarantee the normal operation of the dredging equipment where the specific caisson head is located. Especially for large-scale caisson projects with a lot of equipment and large mud suction volume, the requirements for water and gas supply are high, and failures will seriously affect work efficiency and even delay project progress. Contents of the invention [0003] In view of this, in order to solve the ...
