Containment Propelling Construction Method Utilizing Guide Rail Section Steel

Abstract

The present invention relates to a culvert body propelling method using guide rail steel. After the steel pipe for protection is pressed in to reinforce the ground, when the concrete culvert is pushed, the guide rail steel formed in the steel pipe and joined to the culvert can be used to fine-tune the underground tunnel. The construction can be carried out on the ground, and the impact on the upper ground can be minimized. The feature of the above-mentioned culvert advancing construction method is that it includes: step a), constructing the propulsion base and reaching the base; Insert guide rail profile steel into the steel pipe complex; step d), manufacture culvert at the propulsion base, and make the end of the guide rail profile steel join with culvert; step e), push the culvert; step f), release the culvert and the culvert The joint between the ends of the guide rail section steel; and step g), filling mortar between the outer surface of the above-mentioned containment body and the inner surface of the steel pipe.

Description

technical field [0001] The present invention relates to a construction method of an underground tunnel, and more specifically, relates to a culvert propelling method using guide rail shaped steel. After the protective steel pipe is pressed in to reinforce the ground, when the concrete culvert is pushed, the culvert formed in the steel pipe and connected with the culvert can be used The integrated guide rail steel is used to construct the underground tunnel precisely, and the impact on the upper ground can be minimized. Background technique [0002] The front jacking method, which is one of the preferred methods for constructing an underground tunnel, is used to maintain the soil surface without excavating the ground surface such as roads in order to reduce the impact on roads or rivers located above the underground tunnel. One of the non-excavation methods for constructing underground tunnels under the state of the art, the operation base is constructed before and after the ...
