The present invention relates to a culvert structure for the passage using steel pipe propulsion and its construction method, and more specifically, to the neighboring propulsion steel pipes to be connected to each other, and a propulsion roller is installed on the outside of the steel pipe and a guide roller is installed on the floor. The guide rail is installed to propel the propulsion culvert quickly and conveniently with a propulsion device so that it can be installed without the need for separate branches.PRP for attaching stainless steel to the outside of the culvert for waterproofing of the culvert to reduce waterproof effect and frictional resistance during propulsion. The culvert structure for the passage using the Pipe Roller Pushing Method and its installation method.

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 ship manufactured in the field, it is towed to remove internal soil in the ship, and to repeat the towing and excavation work to install the structure in the ground.

However, this method may cause settlement on the road or stumbling block of the upper part of the enclosure due to the propulsion load of the enclosure or the gap between the propulsion enclosure and the temporary steel pipe installed in the underground. When the scale is increased, the traction is accompanied by control and the size of the workshop is large, so it is difficult to work in a deep underground space.

In addition, if the connection between the enclosures is insufficient, there is a risk of leakage, so the steel pipe loop method is applied to the non-removable underground structure construction method due to the drawbacks of the towing method.

In the conventional steel pipe loop method, the steel pipes are sequentially press-ined and connected to the ground where the structure is formed to form a steel pipe loop, remove all the internal soil inside the steel pipe loop, and construct the structure. Support with 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 lower surface of the primary steel pipe loop with a load-bearing depth, and the steel pipe used for the steel pipe loop is connected in a simple loop shape, so that it is supported by the H-shaped steel in the direction perpendicular to the steel pipe on the bottom and side of the steel pipe loop. 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 addition, since a separate space is required on the upper and side surfaces for branch beam installation, the excavation cross section becomes larger, and it is difficult to secure stability such as settlement of steel pipe roof and branch beam after installation of the steel pipe loop and branch construction. There was this.

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 such a conventional drawback, and to connect the adjacent propulsion steel pipes to form an integral to enable the propulsion of the propulsion culvert without a separate transverse support in the state in which the propulsion steel pipes are aligned. It is done.
