Abstract

The present invention relates to a construction method and a structure of a sewage pipe composite structure foundation structure for constructing a sewage pipe composite structure foundation structure, and more particularly, it is safe to external pressure against lubrication load, earth pressure, side pressure, buoyancy, etc. Then it was invented to be used semi-permanently.

The sewage pipe foundation construction method is to dig the ground soil in the underground space and replace it with sand so that no settlement occurs due to the upper load. Lay down the sewage pipe on top, and fix the sewage pipe not to move through the wedge of the composite structure (FRP + structural square steel pipe) at regular intervals between the sewage composite structure and the sewer pipe.

Next, sewage pipe guards shall be wrapped around the upper part of the sewage pipe at regular intervals and fixed with stainless bolt nuts welded to the sewage pipe composite structure so that the sewage composite structure and the sewer pipe are the same and not moved.

The fabrication of the structure is made of FRP panel by alternately stacking polyethylene resin and glass fiber, and made by welding horizontal and vertical structural steel pipe frames on the FRP panel, and then alternately laminating polyethylene resin and glass fiber to build the sewage pipe composite structure basic structure. It is characterized by producing.

Construction in accordance with this construction method is possible to shorten the air and to construct a structurally perfect sewage pipe composite structural foundation.

Integrated construction of sewage pipe composite structure foundation, sewage pipe and sewage pipe composite structure.

Prior arts of sewer pipes include sleeper foundations, pile foundations, concrete foundations, gravel, and sand foundations. However, sleepers and pile foundations do not last long enough to corrode, and concrete foundations are difficult to shorten air. It is not a reasonable way to relax the foundation.

The new construction method is a semi-permanent structure of sewage pipe composite structure (FRP + structural square steel pipe) base structure can be easily transported and installed as a factory product and the structure is safe and corrosion-resistant.

Fig. 3-a shows the sewage pipe fixing strips anchored at regular intervals on the sewage pipe composite structure (FRP + structural square steel pipe) foundation structure to the upper sewer pipe, fixed with stainless bolt nut, and the synthetic structure wedges are fixed at regular intervals. It is a plan view inserted between the bottoms to fix the sewer pipes so as not to move,

3-b is a side view and FIG. 3-c is a sectional view.

Therefore, it is possible to build the sewage pipe composite structure based on the size and design conditions of the sewage pipe.

Accordingly, it is an object of the present invention to provide a construction that complements the sewage foundation to be a permanent structure according to the use of the composite structure in the application of the construction method through the pre-fabrication of the sewage composite composite structure foundation structure.

It is another object of the present invention to manufacture a structurally safe sewage composite composite foundation structure that does not deform and settle so that the sewage composite composite structure and sewage pipeline do not work separately, and pre-fabricate the sewage composite composite structure. As a problem, in using synthetic resin-based materials, the use selectivity of materials is determined.

Features of the present invention for achieving these objects is the step of laying the bottom surface of the underground space centered around the sewage pipe installation location, the step of lowering the pre-fabricated sewage pipe composite structure basic structure to the underground space using the equipment. A step of laying the sewage pipe composite structure basement put underground into the ground made of soil. Sewage pipe laying the sewage pipe on the composite structure. Sewage Pipe Composite Structure A step of inserting the composite structure wedge between the basic structure and the sewage pipe, and laminating it with FRP between the sewage pipe and the wedge into a single structure. Finally, the sewage pipe joint structure is characterized in that the step consisting of the sewage pipe fixing FRP belt so that the sewage pipe is integrated.

Another feature of the present invention relates to a material used for manufacturing the sewage pipe composite structure basic structure, and to produce a FRP panel using alternating polyethylene resin and glass fiber so as to be safe for wheel load, vertical earth pressure, and sewage pipe weight. The structural square steel pipe frame welded at intervals is put on, and polyethylene resin and glass fiber are alternately used to produce a composite structure, so workability is good and water is not leaked.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The sewage pipe composite structure foundation structure 8 according to the present invention is inserted into the composite structure wedge (2) at a predetermined interval between the sewage pipe composite structure foundation structure (8) and the bottom of the sewage pipe (1) and the sewer pipe fixing belt (1) 9) surround it and fix it so that it does not move.

Sewage pipe composite structure basic structure (8) fabrication is made by placing a frame welded horizontal and vertical structural steel pipes (11) on the FRP panel (14) for alternate reinforcement and laminating (12) polyethylene resin and glass fiber alternately. do.

Synthetic structure wedge (2) fabrication is produced by alternately laminating (12) polyethylene resin and glass fiber on a structural square steel pipe (11) having one end triangular.

Finally, the sewage pipe fixing strip (9) was laminated (12) by alternating polyethylene resin and glass fiber on a semi-circular mold (12) and bent at both ends by 90 ° and bolted to the sewer pipe composite structure (8). Fix and complete the construction of sewage composite composite structure foundation (8).

Thus, in the present invention, the air is shortened in the application of the construction method through the pre-fabrication of the sewage composite composite structure foundation structure, and the surroundings are suitable for the sewage pipe facility, while the base material of the sewage composite structure basic structure uses the synthetic resin and the structural square steel pipe. It is structurally safe and corrosion resistant, making it a permanent structure.
