Auxiliary device for starting and receiving of shield machine

Abstract

The invention discloses an auxiliary device for starting and receiving of a shield machine. The auxiliary device comprises a steel sleeve, a bottom framework, and a bearing board, wherein the steel sleeve is formed by connecting a plurality of sleeve bodies, the bottom framework is arranged at the bottom of the steel sleeve, the bottom framework comprises a plurality of sections, the bottom framework comprises a bottom board that extends along a direction vertical to an axis of the steel sleeve, the bearing board extends along the direction vertical to the axis of the steel sleeve and has a side edge matched with the outer side wall of the sleeve body, the bearing board is vertical to the bottom board, lifting boxes are arranged at two ends of the bottom board, the lifting boxes comprise an external box that is formed by connecting a top board parallel to the bottom board with a part of the bearing board and an internal box that is arranged in the external box, the internal box is internally provided with a hydraulic device, and a plurality of vertical and horizontal steel boards are arranged in a clearance between the internal box and the external box so as to divide the clearance into a mesh structure. The auxiliary device can be used for starting and receiving of the shield machine, also can realize cross-station, lifting and translation of the shield machine, is low in device loss and long in service life.

Description

technical field [0001] The invention relates to tunnel boring equipment in the field of building construction. More specifically, the invention relates to an auxiliary device for launching and receiving of a shield machine. Background technique [0002] The shield tunneling method is a construction method for underground tunneling under the ground. It uses a shield machine to excavate underground. While preventing the soft ground excavation surface from collapsing or maintaining the stability of the excavation surface, the tunnel is safely carried out inside the machine. excavation and lining operations. The starting and receiving of the shield machine is the most critical link in the shield construction, and it plays a decisive role in the success or failure of the project. At present, the closed starting construction method is mostly used for construction. Before the shield tunneling, a steel sleeve is installed in the shield starting shaft, the shield machine is install...

AI Technical Summary

Problems solved by technology

[0003] At present, in the construction process of the shield machine, steel sleeves need to be assembled separately in the starting and receiving constructions, which will consume a lot of manpower and material resources; most of the counter force devices used for shield machine reception on the market adopt frame structures, Especially the "well"-shaped frame; but because the frame is assembled to the steel sleeve after welding, in order to adapt to different terrains, it is necessary to produce frames of various specifications, and at the same time, it is impossible to fine-tune according to the terrain

During the starting process of the shield machine, the existing technology also needs to install multiple jacks between the starting reaction frame and the steel sleeve to buffer the back seat reverse force during shield tunneling, so it is time-consuming and laborious to assemble
