Hydraulicking cutter suction equipment and method for inner support foundation pit engineering

Abstract

The invention provides hydraulicking cutter suction equipment and method for inner support foundation pit engineering. The hydraulicking cutter suction equipment comprises a main rod, a power device and a double-shaft soil reaming device and further comprises a mud sucking pipe embedded in the main rod, and high-pressure water guns arranged on the two sides of the main rod, wherein the high-pressure water guns are connected in from the portion above the power device and extend to be inserted into a fixing plate. The method comprises the following steps that a surface layer soil body is excavated; a first concrete inner support is constructed, and an H-shaped steel track of an electric hoist is installed; a pipeline is laid; the workload is arranged; and hydraulicking construction is carried out. The equipment and the method have the beneficial effects that the structure is simple, operation is convenient, maintaining is easy, the cost is low, soft soil excavation is carried out for foundation pit engineering with the inner support, the efficiency is improved remarkably compared with that of a traditional excavation machine, the construction period of the earthwork engineering is shortened greatly, the influence caused by flying dust is reduced, and the problem of slag and soil transportation and the like is solved.

Description

technical field [0001] The invention relates to the technical field of earthwork excavation equipment, in particular to a hydraulic excavation cutter-suction equipment used for foundation pit engineering with internal support and a small moving space for the equipment and its use method. Background technique [0002] Nowadays, the space above the ground is close to saturation, and underground space projects have begun to develop rapidly. Most projects require foundation pit support, especially deep foundation pits in soft soil. However, the activity space of the foundation pit after the inner support is arranged is narrow. , which greatly restricts the normal work of large excavators, resulting in slow earthwork excavation speed, and at the same time, the earthwork needs auxiliary equipment to be transported to the outside of the pit, prolonging the construction period will cause safety hazards, and the high cost of muck transportation is also time-consuming In addition, it ...

AI Technical Summary

Problems solved by technology

However, in this patent, hydraulic excavation and mud transportation are carried out separately, and there is no integration consideration. In addition, the system has good soil properties for the foundation pit and the excavation efficiency will be greatly reduced when the area of ​​the foundation pit is large.
