Abstract
The utility model discloses a novel direct depth measurement formula plastics drain bar of whole high strength, including the core, still include the filter membrane and measure the muscle, the cross sectional shape of core is cross or great wall shape, the upper and lower surface of core all is equipped with the filter membrane, the middle part of core is equipped with the measurement muscle, measure the length direction setting of muscle along the core, measure the length of muscle and the length phase -match of core, measure the muscle and measure the muscle for the metal, core, filter membrane and measurement muscle high temperature hot melt are as an organic whole. The utility model discloses not only intensity is high, long service life, can squeeze into the degree of depth in the soft base by the direct measurement drain bar moreover, improves quality testing efficiency.
Description
Technical field
The utility model belongs to subsurface drainage field, is specifically related to a kind of novel overall high-strength direct depth-measuring plastic drainage plate.
Background technology
Hydraulic engineering and wharf structure, highway, harbour, sea, river bank protection, in the civil engineerings such as power station, need to carry out base course drainage consolidation.Domestic market uses most time split type plastic draining board.The band drain filter membrane of this form is coated on outside central layer, not bonding with central layer.There are following shortcomings:
A the material of () central layer is plastics, its surrender elongation per unit length is very large, can more than 100% be reached, and the elongation per unit length of filter membrane is very little, its stretch section only has about 10%, central layer and filter membrane common stressed time, can not jointly bear maximum External Force Acting, when filter membrane is broken, central layer only bears less pulling force, causes plastic draining slab integral tensile strength less.
B () filter membrane adopts immersion non-woven fabrics to make, its adhesive is water-soluble, after meeting water, glue can dissolve, geotextiles fiber can scatter, and intensity greatly reduces, when constructing under severe conditions, easily outsourcing rate cover is broken, cause filter membrane and central layer break-off, band drain was lost efficacy, also affect efficiency of construction and increase the loss of material.
C () split type band drain outsourcing filter membrane coated degree of tightness difficulty when producing controls, when coated more loose time, run into lateral pressure filter membrane embedded core groove, decrease drainage channel space, cause plastic draining board ability to decline.
Summary of the invention
For solving the problem, the utility model discloses a kind of novel overall high-strength direct depth-measuring plastic drainage plate, not only intensity is high, long service life, and directly can measure band drain and squeeze into the degree of depth in soft base, improve quality inspection usefulness.
A kind of novel overall high-strength direct depth-measuring plastic drainage plate, comprise central layer, also comprise filter membrane and measuring muscle, the cross sectional shape of described central layer is cross or Great Wall shape, and the upper and lower surface of described central layer is equipped with filter membrane, and the middle part of described central layer is provided with measuring muscle, described measuring muscle is arranged along the length direction of central layer, the length of described measuring muscle and the length of central layer match, and described measuring muscle is metal measuring muscle, and described central layer, filter membrane and measuring muscle high-temperature hot fuse into one.
As further improvement of the utility model, the glutinous non-woven fabrics of bi-component different fusing point heat selected by described filter membrane.
As further improvement of the utility model, described measuring muscle is copper wire or steel wire.
As further improvement of the utility model, described central layer selects polypropylene material.
As further improvement of the utility model, the diameter of described measuring muscle is 0.5mm.
Compared with prior art, the utility model tool has the following advantages and beneficial effect: the glutinous non-woven fabrics of bi-component different fusing point heat selected by filter membrane
,can fuse together with central layer in the situation of being heated, filter membrane and central layer can not be produced when meeting water and peel off stratification, reduce filter membrane what and block up, keep it in water or the long-time stability of underground; In central layer, add measuring muscle, not only direct instrument or directly extract out from soft subgrade soil layer can measure its band drain and squeeze into the degree of depth in soft base, improve quality inspection usefulness, and play the effect of reinforcing rib, improve the intensity of band drain entirety; Central layer is cross or Great Wall shape, and increase displacement, drainage effect is better.
Accompanying drawing explanation
Fig. 1 is cross band drain structural representation in the present invention.
Fig. 2 is Great Wall shape band drain structural representation in the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
As shown in Figure 1-2, a kind of novel overall high-strength direct depth-measuring plastic drainage plate, comprises central layer 1, also comprises filter membrane 2 and measuring muscle 3, and central layer 1, filter membrane 2 and measuring muscle 3 are melt into by high-temperature hot and are integrated.
Central layer 1 prioritizing selection polypropylene material, the cross sectional shape of central layer 1 is designed to cross or Great Wall shape, and drainage effect is better, and the upper and lower surface of central layer 1 is equipped with filter membrane 2, the glutinous non-woven fabrics of material selection bi-component different fusing point heat of filter membrane 2, the osmotic strength > 5*10 of filter membrane
-3cm/s, can fuse together with central layer 1 in the situation of being heated, and can not produce filter membrane 2 and central layer 1 peels off stratification when meeting water, reduce filter membrane what to block up, keep it in water or the long-time stability of underground, because central layer and filter membrane are jointly stressed, so tensile strength is high.
The middle part of central layer 1 is provided with metal measuring muscle 3, and prioritizing selection diameter is copper wire or the steel wire of 0.5mm, central layer is played to the effect of reinforcing rib.Because measuring muscle 3 arranges along the length direction of central layer 1, the length of measuring muscle 3 and the length 100% of central layer 1 match, so can directly with electronic bathymeter according to resistance method of temperature measurement or directly extract out from soft subgrade soil layer and measure its band drain and squeeze into the degree of depth in soft base, improve quality inspection usefulness, guarantee engineering construction quality.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned technological means, also comprises the technical scheme be made up of above technical characteristic.
