Deep foundation pit tunneling robot and operation method thereof

Abstract

The invention discloses a deep foundation pit tunneling robot and an operation method thereof. The deep foundation pit tunneling robot comprises a main support, a tunneling mechanism, a stepping mechanism and a liquefied soil throwing mechanism, the tunneling mechanism and the stepping mechanism are arranged on the main support, the stepping mechanism is suitable for abutting against the wall of a foundation pit to conduct lifting movement, and the tunneling mechanism comprises an excavating assembly and a rotating assembly; the rotating assembly is rotationally connected with the excavating assembly and suitable for controlling the excavating assembly to conduct drilling and reaming operation, the liquefaction soil throwing mechanism comprises a water injection pipe and a slurry pump, the water injection pipe is suitable for injecting water into the deep foundation pit and liquefying shoveled soil generated at the excavating assembly to form slurry, and the slurry pump is suitable for conveying the slurry out of the deep foundation pit, and after mud precipitates outside well, purified water can return to well for continuous use. The deep foundation pit tunneling robot has the functions of self-guiding, self-tunneling, self-soil-throwing, self-out-of-well and the like, drilling, reaming and other operations can be conducted, the soil-throwing process is environmentally friendly, and water resources can be recycled.

Description

technical field [0001] The present application relates to the technical field of foundation pit excavation, in particular to a deep foundation pit excavation robot and an operation method thereof. Background technique [0002] A foundation pit is a soil pit excavated at the foundation design position according to the base elevation and foundation plane size. Usually, foundation pit excavation methods are divided into manual excavation and mechanical excavation. Compared with manual excavation, mechanical excavation is faster. The specifications are uniform and have little impact on the compactness of the roadbed. [0003] However, the existing foundation pit excavation equipment has the following defects: since mechanical excavation usually uses a rotary drill bit for excavation, the rotary drill bit may be stuck in the foundation pit due to internal and external factors after entering the foundation pit, making it difficult to remove, affecting subsequent construction , an...

Problems solved by technology

[0003] However, the existing foundation pit excavation equipment has the following defects: since mechanical excavation usually uses a rotary drill bit for excavation, the rotary drill bit may be stuck in the foundation pit due to internal and external factors after entering the foundation pit, making it difficult to remove, affecting subsequent construction , and the rotary drill bit cannot ream the foundation pit, and the use scenarios are limited. In addition, when excavating deep foundation pits, the process of throwing soil is more difficult and dangerous, which takes up a lot of man-hours and wastes more water resources, which is not enough Environmental friendly
