Abstract

The utility model discloses a seamless plastic resin pile plank capable of being spliced tightly, and particularly relates to bulkhead strips used for blocking soil in river embankments, lakeshores and seashores. Specifically speaking, plastic resin material is used to press and form in one-shot to constitute wave-shaped or M-shaped or Z-shaped pile planks, one of two side edges is of a protruded end sleeve head structure, and the other side edge is of a concave end sleeve head structure. In addition, in all end sleeve heads or a single end sleeve head are or is provided with a piece (row) soil blocking water preventing bulkhead (bulkheads) which is or are used for sealing and protrudes or protrude rib connecting sleeve in a combined building mode, and therefore river water or sea water can be prevented from permeation, and deep sand collapses and land sink can be avoided.

Description

The seamless plastic resin sheet pile that can closely engage

Technical field

The utility model relates to a kind of rivers and creeks dike, loke shore, the gear soil partition wall sheet pile (Bulkhead strips) of seashore, specifically, to consist of wave with extrusion molding of plastic resin material, or M, the sheet pile of Z-shaped plate shape, one of its both sides of the edge are convex end cover header structure, another edge is matrix end cover header structure, and its each or independent end is pullover is provided with sealing with outstanding rib, the pullover fit that is connected of the matrix end of the sheet pile that the convex end of a sheet pile is pullover with adjacent, build and consist of together (row) and keep off the soil partition wall that blocks water, to prevent that river or seawater from infiltrating, sinking in the flood sand domain that subsides, solves the shortcoming that the total sheet pile product of prior art there is no the tight fit of method.

Background technology

At the embankment near water route, rivers and creeks, lake or seashore etc., generally all build up (row) partition wall together with the complete and safety that prevents from seeping water, surging sand subsides to guarantee dike or bank with wood plank, steel plate or mixed earth.Yet cause easily the adjacent soil domain to be sunk.

US Patent No. 4,674 in 1987, and 921 " Hai Bi " have openly disclosed with Corvic (hereinafter to be referred as PVC) and made a kind of partition wall sheet pile that shore protection is used that can be used as.Lateral edges in the left and right sides edge of this sheet pile has convex end pullover (tougue edge) structure, the opposite side edge has matrix end pullover (undercut edge groove) structure, utilize the convex end cover header structure of the chimeric catenation principle of convex-concave another sheet pile that the pullover structural correspondence of matrix end of a sheet pile is adjacent, vertically squeeze in the water route with the chimeric stratum of the embankment on rivers and creeks, lake or seashore etc. and water intersection and prevent sealing infiltration, the surging sand embankment that subsides to build formation (row) wall.A kind of partition wall sheet pile of avoiding near soil domain to sink is disclosed.

According to above-mentioned United States Patent (USP), convenient and easily for the socket that makes sheet pile and another sheet pile of being adjacent, the outer rim of the convex end of sheet pile one side cover header structure and the matrix end of opposite side overlap the distance that the contact surface between the inner edge of header structure is separated by and all are designed to pre-sizing, to avoid too little and the carrying out that the hampering plate pile protection closes of contact surface standoff distance.Otherwise, when contact surface standoff distance during greater than 5mm, although can be connected easily sheet pile, its convex end pullover with the pullover closely fit of matrix end, cause the water capacity easily to be impregnated in this sheet pile suit place, there is no at present good technical solution scheme and overcome these shortcomings.

The utility model content

Technical task to be solved in the utility model provides the fluid-tight modified form plastic resin of a kind of seamless closely fit sheet pile, its structure is very simple, can be with the water in the embankment on rivers and creeks, lake or seashore etc. and water route, block resistance is outside the suit place of sheet pile effectively, make water or seawater can't infiltrate through the soil of embankment, avoid causing the stratum to run off or sink.Simultaneously, the cost of the expense that the manufacturing cost of modified form sheet pile is required with being used in linking sheet pile engineering etc. can reach zero cost.

For solving the above-mentioned closely shortcoming of fit, the utility model provides a kind of plastic resin making sheet stake of seamless closely fit, the technical characterictic of its improvement is: with on the pullover outer edge surface of convex end of one of sheet pile both sides of the edge of prior art and on the pullover inner edge surface of matrix end at opposite side edge each or be provided with separately sealing with outstanding rib, this sheet pile seals the junction sealing that makes adjacent sheet pile with outstanding rib close contact when fit, reach expection the subside function of soil layer of surging sand that prevents from seeping water.
