Abstract

The utility model provides plastic resin bulkhead strips capable of being embedded and sleeved tightly. A tongue edge sleeve head and an undercut groove edge sleeve head both used for connecting and embedding are arranged on the two side edges of each bulkhead strip; one or more protruding ribs for sealing are arranged on at least one of the outer surface of each tongue edge and the inner surface of each undercut groove edge; the cross sections of the protruding ribs are isosceles triangles, the vertex angle of each isosceles triangle is 30 degrees, the base angle of each isosceles triangle is 75 degrees, and the length of the base of each isosceles triangle is less than or equal to 6 mm. According to the plastic resin bulkhead strips, the tongue edges and the undercut groove edges of the bulkhead strips are embedded and sleeved to build an earth-retaining and water-blocking bulkhead, so as to prevent the phenomenon that the land sinks as banks collapse due to the permeation of river, lake water and sea water and sand flood.

Description

Plastic resin screen wall sheet-piles that can tight chimeric socket

Technical field

The utility model relates to a kind of river levee, Hu Di, the shore protection gear soil of sea wall etc. blocks water with screen wall sheet-piles (Bulkhead strips), particularly relate to extrusion molding of plastic tree lipid material and form wave, M, the resin sheet pile of the tabular or hollow of Z or diamond pattern four sides or three column types, these sheet pile both sides of the edge are respectively equipped with for linking chimeric convex one and matrix end cover header structure, and be provided with the outstanding rib for sealing at least one in two ends are pullover, by protruding, the pullover interlocking fit of matrix end is built and is formed together (row) gear soil and block water and shield continuously wall, to prevent that river or seawater from infiltrating the surging sand sagging sheet pile in embankment domain that subsides.

Background technology

Before, be close to the bunding of water route, rivers and creeks, lake, seashore or hillside etc., generally all with wood plank or steel plate or mixed earth, build up together (row) and shield wall and subside to prevent the land surging sand that seeped water, cause the adjacent soil domain to sink to guarantee the complete and safety of dike or bank.

Within 1987, U.S. Pat 4,674, and No. 921, name is called Hai Bi, openly disclosed to using Corvic (hereinafter to be referred as PVC) and make the tabular screen wall sheet-piles of a kind of undaform of using as shore protection.The left and right sides edge of this resin plate-like type screen wall sheet-piles is provided with a convex end pullover (tougue edge), one structure that is matrix end pullover (undercut groove edge), utilize protruding, recessed chimeric catenation principle plate-like type to be shielded to the convex end cover header structure of pullover another sheet pile of structural correspondence of matrix end of wall sheet-piles, stratum in bunding intersections such as water and ,Huo seashores, ,Huo lake, rivers and creeks, vertically squeeze into chimeric link build form together (row) wall with prevent domain by water infiltrate, surging sand subsides bunding, affect the sagging screen wall sheet-piles in soil domain nearby and invent.

For the bending construction that overcomes the landform such as rivers and creeks, lake or seashore and the intensity of strengthening tabular screen wall sheet-piles, the sheet pile of the sheet pile of M type, Z or diamond pattern and three U word columns or two V word column types is US7 for example, the face that is connected of 628,570B2 sheet pile is to adopt the column type resin sheet pile protruding from tabular sheet pile, that the pullover different J type of matrix angles (J shaped hook) pullover and U-shaped pullover (U shaped palymtic module) to form etc. to be disclosed successively use.

But the above-mentioned sheet pile invention that is disclosed use, in order to make sheet pile can very successfully be driven in the convenience of the chimeric socket of another plate Chinese toon and easily, the dealer links on the outer edge surface of convex end cover header structure of chimeric use in these sheet pile both sides that the contact surface space length design of being separated by the inner edge surface with matrix end cover header structure becomes can not be too little and hindered the carrying out of the chimeric socket of sheet pile; Be greater than 5mm, though can easy chimeric socket, it links protruding, the matrix end of chimeric socket use pullover is can't tight chimeric socket, causes the water capacity easily to be impregnated in this sheet pile wall suit place, there is no so far good technical solution scheme and overcomes.

The utility model content

For solving above-mentioned disappearance that can't tight chimeric socket sheet pile, the utility model proposes a kind of plastic resin screen wall sheet-piles that can tight chimeric socket, the both sides of the edge of described sheet pile have respectively for linking chimeric convex end pullover pullover with the matrix end, the at least one outstanding rib for sealing is set at least one in the pullover inner surface of the external surface that described convex end is pullover and described matrix end, the cross section of described outstanding rib is isosceles triangle, and the drift angle of described isosceles triangle is that 30 degree, base angle are that 75 degree and base length are for being less than or equal to 6 millimeters.

This case applicant is through permanent test and making, the chimeric socket of the sheet pile both sides of the edge of existing prior art is linked to the pullover external surface of the convex end of use or be provided with one at least one in pullover inner surface at its matrix end during with the outstanding rib of the isosceles triangle of sheet pile homogeneity material, find the outstanding rib energy close contact sealing of isosceles triangle by this when chimeric socket of each sheet pile, and completed the utility model creation.

The main purpose of the utility model application be to provide a kind of can tight chimeric socket, do not divulge the subside modified plastic resin sheet pile of bunding of water flood sand, this improvement sheet pile only generates by the extruder of existing manufacture sheet pile the convex that links chimeric socket use, carve the rib ditch that setting tool has the isosceles triangle design on the pullover mould of matrix, needn't set up new equipment, very simple with regard to the plastic sheet pile with outstanding rib of making, can be by rivers and creeks, lake, or the water in the bunding on seashore etc. and water route, block resistance is at the chimeric socket place of sheet pile effectively, rivers and creeks or lake water or seawater can't be infiltrated through outside the soil of bunding causes the stratum loss or sink, also improve the manufacturing cost of sheet pile and be used in be connected the sheet pile required time of engineering simultaneously, expense etc., its commercial cost equals zero.

According to the utility model creation, the technical characterictic of its improvement is to be; To close to the both sides of the edge of the sheet pile of prior art, link on the pullover external surface of convex end of chimeric socket use and at least one in the pullover inner surface of its matrix end the outstanding rib for sealing be provided with the isosceles triangle of sheet pile homogeneity material, make this adjacent sheet pile can use the close contact of outstanding rib to seal by sealing in chimeric when socket, reach and there is the subside expectation function of soil layer of the surging sand that prevents from seeping water.
