Description

Tubular fiber band for basic reinforcement revetment and revetment method using the same

The present invention relates to a tubular fiber band for basic reinforcement rafting construction and a raft construction method using the same. More specifically, the present invention relates to a tube-type fiber band that can facilitate the underwater foundation work and provide a robust revetment surface when the relieving surface construction, and a revetment construction method using the same. In addition, the present invention also includes a revetment construction method that can be constructed by using a tubular fiber band on the entire revetment surface when the entire revetment surface must be firmly constructed.

Fiber banks made of high-strength geotextiles are used for shoreline construction, such as banks of various rivers, banks of agricultural drainage, slopes of roads or railways, slopes of dams or reservoirs, and banks of banks of coastal or reclaimed land.

The revetment method using a fiber band is a method of constructing a concrete reinforcement or revetment surface by forming concrete mat by injecting unconsolidated concrete or mortar with high pressure concrete pump between circular textile formwork made of high strength civil fiber. to be.

In the revetment method using a fiber band, the formwork is a permeable cloth, and the surplus mixed water of the flowable concrete or the mortar is discharged by the injection pressure of the pump, so that the curing time is fast and the hardened body of the concrete or the mortar can be formed. have.

This method can be easily installed on land as well as in water, and since the formwork is made of foam, it is possible to form a concrete or mortar mat of uniform thickness by closely fitting to the terrain even in a complex gradient.

Construction using this method is possible to lay out fabrics made to meet the site topography in advance and inject concrete or mortar with high pressure pump to form concrete or mortar mats of a wide area within a short time. Compared with the precast block method, it is faster, more stable, more efficient and more economical, and it has a remarkable work effect, especially in underwater construction. In addition, the fiber band revetment method is widely used in revetment construction because it is constructed with a large area as compared to other construction methods.

A method for constructing a revetment surface using this fiber band and a new fiber band have already been patented by the present inventors as Korean Patent No. 119332. In addition, the present inventors have filed the same patent application as the patent application regarding the environmentally friendly fiber band and the revetment construction method using the same by improving the patented invention.

In the construction of the lakeside, the construction of the area where the bottom surface of the river meets with the lakeside should be completed. This part forms the basis of the revetment construction and is very important for the construction of the revetment surface. This area is the area where water flows, so the earth and sand are scoured, and there is a heaving phenomenon due to the soil load of the riverbank, and also the sinking of the coastal belt constructed by using the fiber band. . Therefore, in order to prevent all of these phenomena, it is necessary to construct the part where the river bottom and the lake face meet. FIG. 1 is a cross-sectional view schematically showing an example of a lake's rake face, in which the bottom part of the river and the lake's rake face meet each other.

1 is usually an area where water flows, so when constructing this area, underwater construction should be done. Therefore, it is very difficult to form a conventional formwork in this area and to place concrete or mortar in the formwork. This is especially true if the flowing water is fast. Due to the difficulty of underwater work, sub-holes may occur.

The present inventors have developed a tubular fiber band which can remove the above-mentioned difficulties and can be constructed completely, and develop the present invention which can be constructed using the same.

It is an object of the present invention to provide a tubular fiber band for basic reinforcement revetment work that can prevent the heave (heaving) of the revetment, prevent the sedimentary scour of the riverbed and the revetment surface, and prevent the settlement of the relieving ball.

Another object of the present invention is to provide a tubular fiber band for rafters that can be easily installed in water.

Still another object of the present invention is to provide a tubular fiber band for the reveter's work that can reduce the construction cost because it can be easily installed without the conventional wooden formwork.

The above and other objects of the present invention can be achieved by the present invention described below. Hereinafter, with reference to the accompanying drawings will be described in detail the contents of the present invention.

The tubular fiber band for basic reinforcement rafting engineering of the present invention is manufactured in a cylindrical shape as a high-strength geosynthetic fiber. A tubular fiber band 1 corresponding to the length of the raft to be constructed by the rafts is manufactured, and a plurality of inlets 3 for injecting mortar or concrete 2 into the tubular fiber bands 1 are formed.

The temporary portion to embed the tubular fiber band 1 is first excavated using a fork-lane or the like, and the tubular fiber band 1 is fixed to the bottom surface of the river. Connect a hose (not shown) through which the mortar or concrete 2 can be supplied through the inlet 3, and the hose is connected to the concrete or mortar tank and kneaded by a pump (not shown). ). When the mortar or concrete (2) is completely injected into the tubular fiber band (1) and cured, the revetment along the revetment surface above it. The revetment work is carried out according to other revetment methods using a conventional fiber band.

The tubular fiber band of the present invention can be applied to an inclined surface. The inclined tubular fiber zone 4 can be suitably applied in consideration of the geographic conditions of the lake, such as a lake surface that requires a stronger strength than aesthetics, or a lake surface that is difficult to construct. The inclined tubular fiber zone 4 is arranged in a row, and mortar or concrete 2 is injected into each tube to form a rake face.

1 is a cross-sectional view schematically showing an example of the river banks, it is necessary to more completely construct the branch area where the river bottom surface and lake banks meet. Therefore, to install a tubular fiber band in the branches along the longitudinal direction of the river is to form a revetment ball.
