The present invention relates to a facility construction method for the passage using steel pipe propulsion and culvert, and more specifically, to install a culvert at the propulsion base and the reach base, and the construction method in the state that the propulsion steel pipes are connected to each other along the outside based on the culvert The process of installing a culvert by removing dirt from the ground relates to the construction of steel pipe propulsion and facility construction using culverts.

In general, there is a structure construction method by the attachment and non-attachment in a way to build the structure in the ground.

When it is necessary to install sewage rock or underground tunnel structures across existing roads and railroads, it is difficult to transfer obstacles due to construction, or it is impossible to fix them due to obstacles or obstacles in vehicle communication. For the construction of the structure by non-adherence, forward and reach bases of the concept of work tools are essential to both sides of the crossing road and stumbling blocks. Can be.

The towing method of the enclosure is to press-through a steel pipe for supporting the housing, which has a predetermined size, in the horizontal direction from the forward base to the reach base, and then traverse the ground from the reach base on the opposite side of the enclosure to be towed. After binding a large number of PC steel wires to a manufactured enclosure on the site, it is towed to remove internal soil in the enclosure and to repeat the towing and landing operations.

However, this method may cause settlement of the road or obstacles on the upper part of the upper part of the hull due to the propulsion load of the hull or when the propulsion hull and the temporary steel pipe installed in the ground are already in the ground. The larger the size, the greater the traction and the greater the size of the workplace.

In addition, if the connection between the enclosures is insufficient, there is a risk of water leakage, and the steel pipe loop method is widely applied as an unattached underground structure construction method due to the drawbacks of the towing method.

In the conventional steel pipe loop method, steel pipe loops are sequentially pressed and connected to the ground in which the structure is formed to form a steel pipe loop, to remove all the internal soil inside the steel pipe loop, and to build the structure. Is supported by temporary materials such as lateral support beams and temporary columns.

In the construction process of the steel pipe loop, the steel pipe loop is formed by horizontally inserting the temporary steel pipe into the outer surface of the sphere in consideration of the size of the sphere to be constructed in the forward base and placing concrete in the steel pipe.

From the forward base, the inside of the steel pipe loop to be constructed is excavated. The excavation is performed step by step from the upper part of the steel pipe loop to the lower side in consideration of the safety of the upper load and the side pressure.

Here, the excavation is to excavate the bottom of the primary steel pipe loop with a depth of about 3m, and the steel pipes used in the steel pipe loops are connected in a simple loop shape, so they are supported horizontally with the H-shaped steel in the direction perpendicular to the steel pipes on the bottom and side of the steel pipe loops. The beams must be installed and supported by a number of temporary columns to support the load over the entire section.

As a result, the existing steel pipe loop is constructed by connecting the steel pipes inserted into the connection structure of the concave-convex structure in which a pair of a-shaped ring and a T-shaped clasp are attached to the end in the center of the steel pipe in the form of a mutual ring, and then the secondary, 3 Due to the problem of extending the installation pillars downward to the installation depth while digging in the car, there is a high possibility of subsidence during construction, and there is a defect that the air is delayed due to a problem with the existing installation materials.

In order to solve this problem, a steel pipe loop structure that can be installed by installing only temporary columns without installing a transverse support beam regardless of the scale or depth of underground construction works when constructing underground structures using steel pipe loops Proposed.

However, the upper and lower slab and the wall portion inside the steel pipe roof structure, but there is no transverse support beam to withstand the load.

Since the culvert, which is a heavy material having a slab and a wall portion inside the steel pipe loop structure, is forcibly pushed, the propulsion is difficult or the friction force is largely generated, which makes the propulsion almost impossible.

The present invention has been made in order to solve the above-mentioned drawbacks, and after forming a culvert on the propulsion base and the reach base, the propulsion steel pipe is aligned by pushing the propulsion steel pipes along the outer surface of the culvert to connect with each other to form an integral. The purpose of the installation is to install the culvert while removing the soil of the construction area between the culverts as much as the section where the culvert will be installed.
