Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal drainage construction, in particular to a tubular closed slag discharging device used for pipe jacking construction. Background Art
[0002] Municipal road drainage construction adopts trenchless pipe jacking construction, generally carried out by earth pressure balance, slurry balance or mechanical excavation. Slurry balance is not suitable for soil layers with high permeability. The soil layers under municipal roads that are easily damaged by water need to be carefully selected for slurry balance excavation. The slurry balance method discharges a large amount of mud, which is not easy to handle. However, compared with earth pressure balance and mechanical excavation, the slurry balance construction process is continuous and fast. The main factor affecting the continuity of earth pressure balance or mechanical excavation is the slag discharge method. Different from the slurry balance that converts the cut soil into mud and discharges it through pipes, earth pressure balance and mechanical excavation generally use carts to transport it to the working well, and then hoist it to the upper working surface. As the distance of the jacking increases, the distance from the excavation surface to the excavation port also gradually increases, and the excavation efficiency gradually decreases, which seriously restricts the jacking speed.
