Long-distance feeding equipment for subway grouting

Abstract

The invention relates to the technical field of subway construction, in particular to long-distance feeding equipment for subway grouting, which comprises a first conveying pump, a conveying unit and a grouting unit, the first conveying pump is arranged in a subway ventilation pavilion, the lower end of the first conveying pump is provided with the conveying unit, and the grouting unit is arranged in a subway tunnel; at present, when grouting raw materials are poured, the following problems exist: most of the current grouting materials are manually carried into a subway tunnel, so that the conveying efficiency of the grouting raw materials is influenced; due to the fact that the weight of the pipeline is increased in the grouting process, workers are difficult to lift the grouting pipeline to move, and the labor amount of the workers is increased; the equipment can replace manual operation to carry grouting raw materials, and the conveying efficiency of the grouting raw materials can be improved; the grouting pipeline can move along with workers, and therefore the labor amount of the workers during grouting raw material pouring can be reduced.

Description

technical field [0001] The invention relates to the technical field of subway construction, in particular to a long-distance feeding device for subway grouting. Background technique [0002] The subway is a fast, large-capacity, and electric traction rail transit built in the city. With the continuous expansion of the construction scale of the subway, the foundation pit is also developing in the direction of "dense, deep, and large". The grouting raw materials are poured into the tunnel, and the safety of the foundation pit and the protection of the surrounding environment are ensured through the grouting reinforcement technology. [0003] During the construction of the subway, in order to facilitate the construction of the subway, a subway air pavilion is usually set up on the ground, and then an air shaft is opened on the ground, and a subway tunnel is opened at the lower end of the air shaft, and the subway air pavilion, air shaft and subway tunnel connected.

AI Technical Summary

Problems solved by technology

[0004] However, the existing technology has the following problems when pouring grouting materials in subway tunnels: 1. Most of the current grouting materials are transported to the subway tunnel by manpower, and then the grouting materials are stirred in the subway tunnel Processing, so a lot of manual handling is required, which affects the delivery efficiency of grouting raw materials, and cannot effectively control the delivery volume of grouting raw materials, and the excess grouting raw materials need to be transported out

[0005] 2. During the grouting process, the weight of the grouting pipe will increase due to the grouting raw materials remaining in the grouting pipe, so the workers will struggle to lift the grouting pipe to move, thus increasing the worker's labor force. Labor load, and it is inconvenient to collect the grouting pipe
