Problems solved by technology

[0004] The problem in the above-mentioned published documents is that the circulation of the hole-clearing mud is realized by using the sealed conduit and negative pressure, but the sealing effect between the sealed conduit and the negative pressure input air pipe and the jetting output air pipe cannot be guaranteed, resulting in insufficient negative pressure to realize the mud circulation. Chiang Khong
Moreover, the gas flow rate of the air compressor and the gas delivery volume of the air pipe are limited and required based on experience only, without scientific and reasonable calculation and verification

Abstract

The invention relates to the technical field of engineering construction, and discloses a large-area underwater foundation pit slag removal analysis method and system. The large-area underwater foundation pit slag removal analysis method comprises the following steps: 1, building an underwater foundation pit slag removal system model, and setting basic variables and decisive variables in the model; 2, creating a water area seasonal flow database, and storing basic data of a water area where an existing project bridge is located; and 3, receiving the predicted net slag discharge amount per hour, and outputting an optimal scheme of equipment type selection of the underwater foundation pit slag removal system model through calculation and analysis. According to the technical scheme, the optimal technical parameters, specifications and models of the equipment are obtained through calculation, and the slag removal efficiency and effect are greatly improved, and the construction quality of subsequent bottom sealing concrete is powerfully guaranteed.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to an analysis method and an analysis system for removing slag from a large-area underwater foundation pit. Background technique [0002] In the deep-water foundation construction of bridge engineering, in order to ensure the pouring quality of the back-sealing concrete, the slag in the underwater foundation pit or cofferdam is often cleaned before the back-sealing construction, and the silt, rock slag and other debris in the foundation pit or cofferdam are cleaned up to ensure The back-sealing concrete has no slag inclusion and weak interlayer. The slag removal methods in the prior art mainly include the slag removal method, pulp replacement method, etc. The slag removal method needs to be equipped with slag removal equipment or ships, and the cost investment is high, and the slag removal is not thorough, and there is still a lot of sediment on the subs...
