Abstract

PURPOSE:To form a slope protection structure together with pipe forms by inserting pipe forms of monolithic structure consisting of longitudinal, lateral, and supporting parts into holes drilled in the slope of a hill and pressure-feeding and filling concrete into the forms, and curing it. CONSTITUTION:Holes 5 are drilled in the inclined surface of a hill at specified intervals. A supporting pipe form 3 of a monolithically formed pipe material consisting of longitudinal lateral and supporting pipe forms 1, 2, 3 is inserted into each hole 5, and concrete 4 is pressure-fed and filled into the pipe forms by a concrete pump and cured, and thus a slope protection struction is formed together with the pipe forms. Sediment fall in taking plate of the inclined sur face of the hill can thus by prevented by a simple construction, the concrete is protected by the pipe forms so as not to be weathered, and semipermanent sheathing of the slope can be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention uses a pressure pipe for placing a concrete pump itself as a formwork or structure.

(Conventional technology) The conventional slope top construction method involves installing prefabricated concrete blocks using a crane or assembling formwork on site.
Place concrete.

(Problems to be solved by the invention) Since there is a lot of on-site work on steep slopes, it is affected by the weather, efficiency is low, the danger rate is high, and because it is exposed, it is easily weathered.
It had a number of drawbacks, such as its short lifespan as a structure, the cost of antifreeze curing, and the color of the concrete which did not harmonize with nature.

This invention was invented to eliminate these drawbacks.

(Means for Solving the Problems) This invention uses a concrete pump to pump and fill concrete into a pipe form made strong against tension, waits for it to harden, and creates a pour-retaining structure together with the pipe form. It forms a ridge and plays a role in preventing the collapse of earth and sand on the mountain slope.

(Example) This invention will be explained with illustrations.

FIG. 1 is a sectional view of the large wooden mold of the present invention.

The vertical pipe form 1, the horizontal pipe form 2, and the support pipe form 3 are integrated. A hole 5 is dug in the slope of the mountain, the supporting vibe formwork 3 is poured, and the concrete 4 is poured into the above-mentioned vibe formworks 1, 2.
Fill to 3.

Figure 2 is a completed elevational view of the proposed large wooden mold.

First, measure the slope of the mountain. Next, dig a hole for the support part. The fir pipe form 1, which corresponds to the leaf part, and the horizontal pipe form 2, which corresponds to the technique part, are laid in a casual manner.

Next, the support pipe form 3 projecting downward is inserted into the previously dug hole. With the above preparations complete, concrete will be pumped from below using a concrete pump truck. Fill it so that it reaches every corner. This process is repeated as many times as there are vertical pipe forms, left to stand quietly, and allowed to harden naturally.

Figure 3 is a completed elevational view of the serpent-shaped structure of this project.

First, the pipe forms 1 are laid so that they are in contact with each other at one point. Next, the support metal fitting 7 is driven into the slope of the mountain, and both of the vibe formworks 1 are fastened together using the fasteners on the head of the support metal fitting 7. The preparation is now complete and the work is completed in the same manner as described in Figure 2.

FIG. 4 is a sectional view of the serpent type of the present invention.

The support fitting 7 is driven into the slope of the mountain, and the pipe formwork is tightened using the metal fitting on the head. Fill with concrete 4 and complete.

The material of the pipe formwork does not matter, such as plastic, metal, cloth, nylon, etc. Note that the filling material is not limited to concrete, and may be of any material such as mortar, plastic, or ceramic.

(Effects of the invention) As described above, if construction is performed on the slope of a mountain using the direct pouring method using a concrete pump, on-site work will be easier.
It's less dangerous and costs less. The concrete is also protected by the pipe formwork and does not weather, allowing it to serve as a semi-permanent earth retainer. It is also easy to create shapes and colors that harmonize with nature.
