Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is a method for constructing slope frames constructed for slope protection by folding and assembling plates made of water-resistant materials. This relates to a pouring method that uses a formwork material for legal frameworks that has holes.

(Prior Art) Currently, various types of slope frame materials are used to protect slopes, and their cross-sectional dimensions are generally 10 cm square or larger. If it is made of concrete, it is heavy and bulky, so it requires a large area for storage in a warehouse or the like, and there is a problem in that the transportation cost for bringing it to the site is also high.

(Problem to be solved by the invention) Therefore, since assembling on a slope requires a lot of labor, after the lightweight formwork is assembled and installed on the slope, mortar, concrete, etc. are poured into the hollow part. There is a method of forming a gravimetric slope by injecting animals, but the formwork used for this method is still bulky, and the current situation is that it has not solved storage problems or reduced transportation costs.

As a result of various studies on new methods that can solve the problems of the formwork materials used in the construction of conventional legal frameworks, the inventors of the present invention found that water-resistant materials such as plastic and cardboard having a certain thickness and length were used. A joint for gluing is provided at at least one end of the plate, and there are three rows of score lines along the direction of the joint, and a certain size is provided on the surface between the score lines or the longitudinal ends. It was concluded that the above-mentioned problems could be solved by assembling plates with parallel holes on-site to form a formwork material having transparent holes with hollow rectangular end faces, and thus arrived at the present invention. did.

(Means to solve the problem) The configuration of the present invention will be explained below based on the drawings.

At least one end of a water-resistant plate 1 such as plastic or cardboard having a certain thickness and length is provided with an adhesive portion 5 having an adhesive portion 5 coated with adhesive or adhesive tape affixed, The plate body has three rows of groove lines 2 along the direction of the joint, and a number of holes 3 of a certain size are arranged in parallel at the ends of the groove lines and the longitudinal direction or between the groove lines. They are assembled as shown in Figure 2 to form a formwork material having a through hole 3 having a hollow rectangular end face shape.

Although the adhesive joint 4 shown in FIG. 1 may be omitted, if it is provided, the joint will function as a drainage flange when assembled as shown in FIG. 2. The through holes 3 have the function of reducing the weight of the formwork material and squeezing out excess water from kneading the fluid by injection pressure.

The formwork materials explained above are assembled using a generally known method.
Insert formwork materials into the joints in a lattice pattern using E-shaped joints, connect them using bolts and nuts, and secure with anchors.

Once this assembly is completed, fluid mortar or concrete is injected from the upper part of the formwork to construct a legal framework, and the inside of the legal framework is filled with soil bags or additional soil for vegetation, and the legal framework construction method is completed. Complete.

(Effects of the Invention) As described above, the present invention comprises forming a slope by assembling and installing formwork materials having through-holes with hollow rectangular end faces in a lattice shape on a slope, and then allowing flow to flow from appropriate locations on the top. Since this is a method of constructing a legal frame by injecting it, it is ideal for work at high places or on steep slopes, and it is possible to form a strong legal frame that is integrated by weight.

Moreover, the weight method frame for secondary concrete products, etc.
It has the function of holding down the ground due to its weight,
The slope constructed according to the present invention is constructed by assembling and installing lightweight formwork materials with hollow rectangular holes on the slope surface, and then pumping up and injecting fluid into the hollow portion from an appropriate location on the top. As a result, workability is dramatically improved, and since the frame becomes heavy after pouring, it has the same function as a weight method frame to hold down the ground, and prevents the method frame from floating due to frost pillars or frost heaving. Over time, the earth retaining function as a legal framework no longer deteriorated.

Additionally, due to the through holes provided on each side, the excess moisture in the mixing water of the fluid is quickly squeezed out of the formwork by the injection pressure, reducing the water pressure applied to the formwork material. It is possible to reduce the weight by reducing the wall thickness of the concrete, and since the water-cement ratio is reduced, the curing time is increased, and a high-density, high-strength integrated frame body is obtained, which prevents the joints from breaking and collapsing. It's gone.

Furthermore, the present invention allows mold materials to be formed by easily assembling water-resistant plates such as plastic and cardboard having a certain thickness and length on-site, thereby eliminating the need for storage space as in the past. This results in a significant reduction in transportation costs.
