Abstract

The invention discloses a space enclosing structure convenient for opening a door opening, which consists of a door opening portion and a periphery portion around the door opening portion. The door opening portion is a slotted section corresponding to a proper caliber size for the access of a tunneling machine; and the slotted section is filled with soil cement and vertically inserted with a plurality of H-shaped steels in sequence so as to form a profiled bar retaining wall that can block water and satisfy the rigidness required for digging a foundation ditch. The invention also discloses a construction method of the space enclosing structure convenient for opening the door opening, an out-start well method and an in-reception well method using the space enclosing structure convenient for opening the door opening. The invention can avoid the labour capacity required for manually opening the door opening, can save the working period and effectively reduce the construction risk. As additional large-scale devices are unnecessary to be installed and the H-shaped steel can be recycled, the invention also has the advantages of simple construction and low construction cost.

Description

Technical field

[0001] The invention relates to the field of building construction, in particular to an enclosure structure that is convenient to open a door and a construction method and a use method thereof. Background technique

[0002] The existing pipe jacking and tunnel construction have two key processes: exiting the launch well and entering the receiving well. In these two key processes, the sub-process of "opening the door" is involved. "Door opening" is to remove the enclosure structure that needs to be traversed when the tunneling machine passes, or to directly design the enclosure structure into a structure with higher bending strength but lower shear strength, such as NOMST (Novel Material Shield) -cuttable Tunnel-wallSystem, the method of shield directly cutting new material wall) adopts carbon fiber reinforced floor wall, so that the tunneling machine such as shield machine or pipe jacking machine can directly cut the enclosure structure.
