Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pouring frame construction method that uses a form material having a drainage part when constructing a slope frame constructed for slope protection.

(Prior art) Various types of slope frame materials are currently in use, but their assembly requires work at high places or on steeply sloped surfaces, and it is not easy to construct the slope along the undulations of the slope. ,
BACKGROUND ART The use of lightweight frame materials such as plastics, which are easy to assemble, has been replaced by heavy materials such as secondary concrete products.

The use of lightweight legal framework materials improves workability at high places and on steeply sloped surfaces, but because of their light weight, frost pillars and frost heave can cause the framework to lift up, reducing the soil retaining function of the legal framework, and causing condensation. There is a problem that the connecting part breaks and collapses.

Furthermore, after constructing the legal framework, the inside of the frame is often covered with soil for greening or filled with chestnut stones, but in this case, rainwater permeates into the soil and chestnut stones and flows down the slope along the surface of the ground. As a result, erosion and weathering of the ground were accelerated, resulting in slope deformation, the earth retaining function of the legal framework was reduced, and the soil and chestnut stone collapsed, often leading to slope failure. In addition, when vegetation growth was poor, the legal framework often harmed the landscape of Medachi slopes.

As a result of various studies on a method for constructing a new legal framework that can solve the problems of conventional legal frameworks, the present inventors assembled a lightweight hollow rectangular formwork material with a drainage section on the slope. After installation, the authors came to the conclusion that the drawbacks of the conventional method of constructing a legal framework could be overcome by constructing a legal framework by injecting fluid into the hollow portion from an appropriate location at the top, and thus arrived at the present invention.

That is, the present invention provides a formwork made of synthetic resin or the like and having a fixed length and a hollow rectangular end face, with a protruding edge on one side of the upper surface, through holes on at least both sides, and a water collection layer on the lower surface. This is an injection frame construction method in which the provided formwork is assembled and installed on a slope, and then constructed using formwork that has a drainage part for injecting fluid into the hollow part.

(Configuration of the present invention) The configuration of the present invention will be explained based on the drawings.

It is desirable to use high-density polyethylene as the material for the formwork used in the present invention because it is lightweight and has excellent strength.

As shown in Fig. 1, the formwork material 1 has a hollow rectangular shape with a protruding edge 2, that is, a flange, on one side of the upper surface, and an L-shaped portion formed by this protruding edge and a surface A formed after pouring. The water collection and drainage layer 3 provided on the formwork material is made of palm pine whose surface is coated with synthetic resin or the like in a U-shape, or synthetic resin pine with spaces, and has the function of collecting and drainage of seepage water. ing. The upper surface A of the formwork material does not need to have through holes when pouring fluids such as mortar or concrete, but when pouring fluids mixed with vegetation base materials (seeds, fertilizers, soil, organic compost, etc.) A through-hole is provided to allow vegetation to grow through buds.
In addition, the through holes B and C have the function of drawing out excess water in the mixing water of the fluid by injection pressure.

As shown in Fig. 2, the joint 4 that connects the formwork material has a drainage layer 5 on the bottom surface to fill the flat space created by inserting the rectangular formwork material. It functions to drain the water collected in the layer to the bottom.

The formwork materials explained above are assembled by a generally known method, using cross-shaped, K-shaped, T-shaped, L-shaped, and E-shaped joints having the connected drainage layer 5 of the drainage collection layer 3. Insert the formwork material in a lattice pattern into the joint, insert bolts into the nuts 6 provided in the joint, connect, and fix with assembly anchors.

Once this assembly and fixing is completed, mortar or concrete, or in some cases, liquid vegetation base material, is injected from the upper part of the formwork to construct the legal frame.
The inside of the legal framework is filled with soil bags and additional soil to create vegetation, and the legal framework construction method is completed.

(Effects of the present invention) As described above, the present invention provides a frame material having a hollow rectangular end face shape and having a fixed length and is molded from synthetic resin, etc., and has a protruding edge on one side of the upper surface, and has through holes on at least both sides. However, this construction method involves assembling and installing formwork materials with a water collection layer on the bottom surface on the slope, and then injecting fluid into the hollow part using a pump-up to construct the slope. It is ideal for working on steep slopes, and allows you to build a strong legal frame with its weight. still,
Weight-bearing frames such as secondary concrete products have the function of pressing down on the ground due to their weight, but the frame constructed according to the present invention is a hollow end face shape with a fixed length molded from synthetic resin or the like. After assembling lightweight rectangular formwork on a slope, it is made heavier by injecting fluid into the hollow part, so it has the same function of pressing down on the ground as a heavy method formwork. As a result, the frame is no longer lifted up by frost pillars or frost heaving, and its function as a legal frame no longer deteriorates.

Additionally, due to the through holes provided on both sides, excess water from the mixing water of the fluid is quickly drawn out of the formwork by the injection pressure, reducing the water pressure applied to the formwork material. The weight can be reduced by reducing the thickness of the wall, and when pouring mortar or concrete fluid, the excess water in the mixing water oozes out through the holes, reducing the water-cement ratio and reducing the curing time. A high-density, high-strength, integrated legal frame body was obtained, and the problem of joints breaking and collapsing due to frost pillars, frost heaving, etc., was eliminated.

Furthermore, by injecting the vegetation base fluid into the hollow part of the formwork, the vegetation will germinate and grow from inside the formwork and cover the formwork, so the formwork will not harm the Medachi slope landscape. Summer.

Furthermore, the surface water is removed by the protruding edge provided on one side of the upper surface of the buried formwork, and the permeated water is discharged by the drainage layer provided on the lower surface. The soil has stabilized, erosion of the ground has been prevented, and its function as a legal framework has not deteriorated over the long term.
