Abstract
The invention discloses an overlapping device of upper geotechnical cloth of a composite geo-membrane. The device is characterized by comprising a bottom plate (1) and a top plate (6) located above the bottom plate (1), wherein one end of an upper steel strip (3) is connected with the top plate (6), while the other end is connected with one end of a middle steel strip (4). The other end of the middle steel strip (4) is connected with one end of a lower steel strip (5), while the other end of the lower steel strip (5) is connected to the bottom plate (1). A needle out device (7) is installed at the bottom of the top plate (6) which is provided with a needle bearing plate (2) adaptive to the needle out device (7) in position. When the device provided by the invention is operated, two pieces of geotechnical cloth are clamped in appointed positions, and the device is moved while the cloth is pressed and sewed, so that the composite geo-membrane is conveniently overlapped.
Description
Technical field
The present invention relates to the lap device of a kind of composite geo-membrane upper strata geotextiles, specifically relate to overlapping mode and the construction method thereof of the upper strata geotextiles in a kind of composite geo-membrane.
Background technology
Composite geo-membrane is mainly used in the antiseepage of the geotechnical engineerings such as earth and rockfill dam, the isolation of railway bed and the outer lotus of diffusion etc., and its form is divided into cloth one film and two cloth one films etc., in use inevitably needs to carry out opposite joint overlap joint by between the geotextiles of upper strata.One deck geotextiles is generally without the need to sewing up (trail, be folded into one piece all right) below, only geomembrane need be welded, above the hand-held sewing machine of one deck geotextiles sew up.But upper strata geotextiles is after this hand-held sewing machine is sewed up, due to only to staying limit to sew up according to length direction, its place of sewing up can only have little part to bear pulling force, and unnecessary stays limit disallowable.This mode sew up after upper strata geotextiles between suture zone very narrow, so be difficult to bear larger tensile stress; Lap-joint has a lot of upper strata geotextiles more than needed not to be utilized, and causes the waste of material.
The overlap joint that the present invention is just aimed between topsoil work cloth is sewed up, the lap device of a kind of composite geo-membrane upper strata geotextiles of proposition and construction method thereof.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide and a kind ofly decrease the tensile stress sewing up place, extend the lap device of the composite geo-membrane upper strata geotextiles in geotextiles application life.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The lap device of a kind of composite geo-membrane upper strata geotextiles, it is characterized in that: it comprises base plate, top board, top board is positioned at above base plate, steel band one end, top is connected with top board, the other end is connected with steel band one end, middle part, and the other end of middle part steel band is connected with lower steel belt one end, and the other end of lower steel belt is connected to base plate, the bottom of described top board is provided with out needle device, base plate be provided with described go out needle device position adapt to hold needle plate.
The bottom of described base plate is provided with roller.
Described top board is provided with handle.
Compared with prior art, the invention has the beneficial effects as follows:
On the one hand, the gap of the zigzag formed after utilizing two geotextiles freely to overlap dexterously, mixes zigzag steel bar, plays gearing; On the other hand, by seam area greatly improve (suture zone 12 significantly than traditional method stitch out loose).This is retarded with regard to making the stress at the place of sewing up concentrate, and decreases the tensile stress sewing up place simultaneously, is conducive to making full use of material, extends the application life of geotextiles.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that lap device of the present invention operation runs sketch.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1, the present invention it include base plate 1, top board 6, top board 6 is positioned at above base plate 1, top steel band 3 one end is connected with top board 6, the other end is connected with middle part steel band 4 one end, and the other end of middle part steel band 4 is connected with lower steel belt 5 one end, and the other end of lower steel belt 5 is connected to base plate 1.Top steel band 3, middle part steel band 4 and lower steel belt 5 form zigzag, and joint makes zigzag steel band have elasticity.。The bottom of described top board 6 is provided with out needle device 7, base plate 1 be provided with described go out needle device 7 position adapt to hold needle plate 2.Go out needle device 7 and can adopt the structure being similar to stapler pattern.The bottom of described base plate 1 is provided with roller 9, top board 6 is provided with handle 8, and control device advances.
Fig. 2 is the schematic diagram of the present invention when operating, right side geotextiles 10 is clipped between top steel band 3 and middle part steel band 4, left side geotextiles 11 is clipped between middle part steel band 4 and lower steel belt 5, go out needle device 7 one end constantly to press down and sew up, because steel band junction all has elasticity, so again can resilience after pressing down at every turn, now need control handle that whole device is retreated, prepare the stitching of next pin.So the process sewed up is similar to use stapler.In a word, during operation, only two-layer geotextiles need be clipped in assigned address, press down and sew up mobile device, just can realize the overlap joint of composite geo-membrane easily.
The undeclared part related in the present invention is same as the prior art or adopt prior art to be realized.
