Abstract
The present invention facilitates the bonding between eco-friendly precast concrete box structures by embedding pre-fabricated pre-cast concrete structures in the basement, preventing leakage of water and soil into the PC box structure, The present invention provides an eco-friendly precast concrete box structure capable of safely protecting a concrete structure.
Description
The present invention relates to a method for forming an underground tunnel structure for embedding a pre-cast concrete box structure (hereinafter referred to as a PC box structure) in a basement to form artificial waterway, a cable, a gas pipe, etc., The present invention relates to an eco-friendly precast concrete box structure which is easy to install so as to be continuously connected to each other, and which is simple to assemble and can shorten air.
The concrete box structure, which is generally called a rock, is used to form an artificial channel, buried underground, or to accommodate city facilities such as cables and gas pipes and to protect them from external impacts.
Reinforced Concrete (RC) method is mainly used as a construction method to purchase the above-mentioned urban facilities underground, in which a formwork is set up at a construction site to reinforce the concrete and cast concrete.
The above-mentioned construction method has a disadvantage in that it delays the flow of roads and deliveries during the period of construction, causes noise to the surroundings, and increases the construction period until the concrete is cured. Recently, Precast Concrete (PC) method, which is constructed by pouring concrete into a mold, and assembling the prefabricated member to the construction site, is increasing.
The PC member produced by the above PC method is installed in the basement and various kinds of city facilities are installed in the inside of the PC member. However, in order to prevent water, soil and the like from flowing into the PC member, However, there is still a problem in that additional labor is consumed and the construction period is lengthened due to the post-processing operation.
Therefore, there is a need for an eco-friendly precast concrete box structure having a new structure capable of solving the problems of the conventional PC member as described above.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a PC box structure in which easing of environment friendly precast concrete box structures is facilitated, leakage of water and soil into the PC box structure is prevented, It is an object of the present invention to provide an eco-friendly precast concrete box structure capable of safely protecting a facility.
