Continuous excavation method and device for underground continuous wall

Abstract

The invention discloses a continuous excavation method and device for an underground continuous wall, and relates to the technical field of building construction machines. The method includes the following steps that the path of the continuous wall is determined, and a guide hole is excavated to the assigned depth; an excavation machine is hoisted and placed in the guide hole through a crane and the like; and excavation is started, and front wall soil can be excavated through the excavation machine, conveyed to the upper rear portion to a soil conveying device and conveyed outwards through the soil conveying device. The excavation device which is used comprises an excavation system, a walking system and a power system. The excavation system comprises an excavation caterpillar band, excavation driving wheels, driven wheels and guide wheels. The outer ring face of the excavation caterpillar band is provided with shovel heads and soil conveying grooves at intervals. The excavation driving wheels and the driven wheels are arranged in the excavation caterpillar band. The working face of the excavation caterpillar band conducts transmission vertically and upwards. The excavation system and the walking system are connected. By means of the continuous excavation method and device, soil excavation and conveying can be synchronously conducted, the energy consumption is lowered, the construction efficiency is greatly improved, and the excavation device is convenient to assemble and disassemble and convenient and fast to use.

Description

technical field [0001] The invention relates to the technical field of building construction machinery, in particular to a continuous excavation method for an underground continuous wall and an excavation device thereof. Background technique [0002] The underground diaphragm wall is a kind of trenching machine used on the ground for basic engineering. Along the peripheral axis of the deep excavation project, a long and narrow deep trench is excavated under the condition of mud retaining wall. After the trench is cleaned, it is hung in the trench Reinforcement cages, and then use the conduit method to pour underwater concrete to form a unit trough section. In this way, a continuous reinforced concrete wall is built underground as a water interception, anti-seepage, load-bearing, and water-retaining structure. [0003] Diaphragm walls have been and are being used in many aspects of foundation engineering instead of many traditional construction methods. In its initial stage,...

AI Technical Summary

Problems solved by technology

[0004] In the current underground diaphragm wall construction, the construction machinery cannot excavate and move the soil simultaneously. During the construction, a large crane needs to be used to repeatedly lift and lower the excavation device. The effect is slow and the consumption is large, which cannot meet the increasingly rapid construction progress. need
