Description

Plastic resin screen wall sheet pile that can be tightly fitted

The present invention relates to a bank wall, a lake embankment, a seawall, and the like, and a Bulkhead strips for water repellent and water blocking. In more detail, the plastic resin material is extruded at one time to form a wave, M, Z or A resin plate pile of a diamond-shaped plate shape or a hollow four-sided or three-sided column type, which has a convex shape for joining and fitting on both side edges, a concave end sleeve structure, and is provided on each of the individual end sleeves The sealing ribs are sealed, and the convex and concave end sleeves are embedded and assembled to form a (row) retaining water-resistant continuous screen wall to prevent river water or seawater from infiltrating into the slab piled by the collapsed bank of the sand.

In the past, banks near the waterways, rivers, lakes, beaches or hillsides generally built a (row) screen wall with timber or steel plates or concrete to prevent the land from being collapsed by water and sand, leading to adjacent soil. Site sinking to ensure the integrity and safety of the bank or shore.

In U.S. Patent No. 4,674,921, the entire disclosure of which is incorporated herein by reference in its entirety, the utility of the utility of the utility of the utility of the utility model of The left and right side edges of the resin-made panel-shaped wall panel pile are provided with a convex end edge and a concave cut edge structure, and the plate-shaped screen wall is formed by the convex-concave fitting connection principle. The concave end sleeve structure of the sheet pile corresponds to the convex end sleeve structure of the other sheet pile. In the stratum where the water meets the river, or the lake, or the shore, the vertical joint is inserted into the joint to form a wall. In order to prevent the site from being infiltrated by water, the sand collapsed into the bank, and the screen wall piles that affected the subsidence of the soil site were invented.

In order to overcome the bending construction of terrain such as rivers, lakes or coasts and to strengthen the strength of slab-shaped screen wall piles, M-type, Z- or diamond-shaped sheet piles and three-sided U-shaped column or two-sided V-shaped column type sheet piles For example, the joint surface of the US 7,628,570 B2 sheet pile is convex and concave with the plate-shaped sheet pile. A columnar resin sheet pile composed of a J shaped hook head and a U shaped palymtic module having different types of heads is used in succession.

However, in the above-mentioned publicly used sheet pile invention, in order to facilitate the smooth and easy entry of the sheet pile into another sheet pile fitting and socketing, the manufacturer has joined the convex end of the fitting on both sides of the sheet pile. The distance between the outer surface of the ferrule structure and the inner surface of the concave end ferrule structure is designed to be too small to hinder the splicing of the sheet pile; more than 5 mm, although it can be easily fitted and spliced However, the convex and concave end sleeves for connecting the fitting sleeves cannot be closely fitted and sleeved, so that water is easily infiltrated into the wall of the sheet pile, and there is no good technical solution to overcome it.

In order to solve the above-mentioned lack of tightly fitting sleeves, the applicant of the present invention has long been tested and produced on the outer surface of the male end sleeves of the existing sleeves of the prior art. Or on the inner surface of the concave end sleeve, each of which is provided with a protruding rib of an isosceles triangle of the same material as the sheet pile, and it is found that each of the sheet piles can be protruded by the isosceles triangle when the sleeve is sleeved The ribs can be closed in close contact and the new creation is completed.

The main object of the present invention is to provide an improved plastic resin sheet pile which can be closely fitted and sleeved, and which is impervious to water leakage and collapse of the bank. The improved sheet pile only forms a joint fitting socket for the currently manufactured sheet pile extrusion machine. The embossed groove with the isosceles triangle design is engraved on the mold of the convex and concave ferrules. It is extremely simple to form a sheet pile with protruding ribs, which can be used to make rivers, lakes, or shores of the sea. The water of the embankment and the waterway effectively blocks the fitting of the sheet pile, so that the river or the lake or the seawater cannot penetrate into the soil of the bank, causing the formation to be lost or subsided, and also improve the manufacturing cost of the sheet pile. And the time, cost, etc. required for connecting the sheet pile works, the commercial cost can be said to be equal to zero.

According to the novel creation, the improved technical feature is that the two sides of the sheet pile closest to the prior art are joined to the outer surface of the convex end sleeve of one of the fitting sleeves or the inner surface of the concave end sleeve. Separately or separately provided with an isosceles triangle of the same material as the sheet pile The protruding ribs are sealed so that the respective sheet piles can be closed by the close contact of the sealing protruding ribs when the fittings are sleeved, thereby achieving the intended function of preventing the water and sand from collapsing the soil layer.
