Machine for forming underground continuous water-retaining walls by one step

Abstract

The invention discloses a machine for forming underground continuous water-retaining walls by one step, which relates to a machine for building underground continuous water-retaining walls on mudflat sections and dam bodies beside rivers, lakes and seas. The machine comprises a tracked chassis, a stand, a turning angle chassis, a grooving system installed on the turning angle chassis, a bar arrangement system, a concrete pouring basin, a power system installed on the stand, an electrical apparatus control cabinet and a hydraulic control cabinet, wherein the grooving system is a chain-type uninterrupted clamshell excavator which can ascend upwards, descend downwards, keep upright in operation and lie obliquely on the stand in transition transporting; and the bar arrangement system and the concrete pouring basin are arranged at the back side of the grooving system. The machine can complete all the operations of digging ground grooves, arranging steel bars and pouring concrete. The machine provided with a diesel engine is fitted with an on-vehicle concrete mixer and has the advantages of flexible transition operation and high working efficiency. The depth of a wall body is adjustable, and a formed wall has favorable quality. The machine can also utilize commercial power of a construction site as power.

Description

technical field [0001] The invention relates to an engineering machine, in particular to a machine for building an underground continuous water retaining wall on tidal flat sections and dam bodies of rivers, lakes and seasides. Background technique [0002] my country has thousands of kilometers of coastline, countless criss-crossing rivers and rivers, and lakes and wetlands dotted with stars. The development and utilization of tidal flat areas, such as wharfs, freight yards, bathing places, marine aquaculture and other major projects are in urgent need of construction. To develop tidal flats, one or several underground continuous water retaining walls must be built first, and the water in the water retaining walls must be drained before construction. In addition, during the heavy rain season, the water levels in rivers, rivers, and lakes remain high, and the dams are soaked in water for a long time, which easily causes dams to leak, and in severe cases, dams burst and caus...

AI Technical Summary

Problems solved by technology

For the construction of the water retaining wall, it is not ideal to use the high-pressure rotary grouting pile machine or the cement mixing pile machine at present. The former cannot build a continuous water retaining wall, and the latter cannot be constructed when it encounters quicksand. It can only be constructed manually. Long construction period, low production efficiency and high construction cost

The continuous water retaining wall of the artificial building has a small depth and low strength. When the seawater tide rises and the water level is high during the rainy season, the artificially built dam is prone to leakage and dumping, causing unsafe accidents
