Rapid unearthing system for top-down ultra-deep foundation pit and construction method of rapid unearthing system

Abstract

The invention discloses a rapid unearthing system for a top-down ultra-deep foundation pit and a construction method of the rapid unearthing system. The rapid unearthing system comprises supporting legs, an equipment frame, lifting trolleys, hanging boxes, cables, a cab, an earth excavating machine and a dumper. The supporting legs are correspondingly connected to a platform at intervals. The supporting legs are correspondingly connected to a platform at intervals. The equipment frame is arranged on the supporting legs. The two ends of the equipment frame exceed the side faces of the corresponding sides of the platform correspondingly. The equipment frame comprises main beams and secondary beams. The main beams are connected to the supporting legs. The secondary beams are connected betweenthe adjacent main beams. Protective railings are arranged on the equipment frame along the peripheral edges. The lifting trolleys are installed on the main beams correspondingly. Winches are connected to the lifting trolleys. The hanging boxes are hung below the lifting trolleys through hanging tools. The cab is installed on the side faces of the supporting legs. The cables are connected betweenthe cab and the lifting trolleys, between the lifting trolleys, and between the lifting trolleys and the hanging boxes. The earth excavating machine is arranged at the bottom of the foundation pit. The rapid unearthing system solves the problems that in the prior art, the construction efficiency is low, the cost is high, the number of adopted machines is large, and the occupied space of the machines is large.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a rapid excavation system and a construction method for inverting an ultra-deep foundation pit. Background technique [0002] The site of a certain project was formed by reclamation from the sea. The original landforms are coastal beaches and coastal cliffs. The southeast section is sandy beach, and the northwest section of the coast is cliffs. The seabed slopes gently from the coastline to the open sea. Two circular deep foundation pits with a diameter of 100m and a depth of 50m need to be excavated on the site. The distance between the two foundation pits is 31m, and the enclosure system consists of a ground connection wall and an inner lining wall. Traditional earth and rock excavation mainly adopts long-arm hooks, grabs, etc. to take soil and stones. It needs to accumulate soil in the foundation pit, grab, lift, load and unload it into the transport vehicle, and...
