Waterproof steel plate installation method using waterproof steel plate propulsion set and method of forming underground composite structure using the same

摘要

The present invention is to connect and install a number of steel pipes long press-fitted into the ground along the tunnel construction surface with a waterproof iron plate, but a specially made waterproof iron plate propelling set, that is, a press-fitted steel material such as an H-beam on the bottom surface. A waterproof iron plate installed by welding is placed on the upper side, and a lower support plate connected to the waterproof iron plate and the earth pressure support is placed on the lower side of the waterproof iron plate, so that the tip of the waterproof iron plate protrudes more than the tip of the lower support plate, A separate waterproof iron plate propelling set is used to connect the left and right side walls to a predetermined length from the tip of the waterproof iron plate to the tip of the lower support plate and to have a sharp rectangular opening box at the top. Disclosed is a method for installing a waterproof steel plate for connecting a steel pipe in a special way that can easily, safely and quickly install a steel pipe. In addition, using this special method of installing a waterproof steel plate for steel pipe connection, various types of concrete composite materials are welded to the inside of the steel pipe where the waterproof iron plate is connected and installed so that the waterproofing can be achieved perfectly, such as reinforcing bars and earth pressure support. Disclosed is a method for forming a non-interleaved underground composite structure that is economical by reducing the number of installations and can obtain a structurally more robust permanent composite concrete structure by integrating the steel pipe, which is a simple temporary material, with the concrete, which is the main structure, during concrete curing.
