Abstract

The utility model provides a plastic drainage blind ditch which comprises a filter core, wherein the filter core is formed by stacking plastic strips; the plastic strips are randomly arrayed; the contact points of adjacent plastic strips are mutually spliced in a fusing way to from a three-dimensional reticular structure; gaps are arranged among the plastic strips; a pore path is formed in the filter core and enables the filter core to be internally and externally communicated; external water flow is permeated into the filter core from the pore path and drained from the end part of the filter core; the filter core is externally provided with a filter membrane; the filter membrane is coated on the surface of the filter core to prevent impurities from blocking the pore path, and the filter membrane is made from a nonwoven geotextile; the filter core is in a strip shape; the cross section of the filter core is circular; the filter core is internally provided with a pipe cavity; the pipe cavity extends along the axial direction of the filter core; water flow is collected into the pipe cavity after being permeated into the filter core; and the cross section of at least one pipe cavity is circular. The plastic drainage blind ditch provided by the utility model has the advantages of high surface opening percentage, good water collection, good water drainage, high compression resistance, good durability, light weight and greatly reduced labor intensity and high working efficiency of constructors.

Description

A kind of plastic drainage French drain

Technical field

The utility model relates to drainage, relates in particular to a kind of plastic drainage French drain.

Background technology

The effect of plastic blind-ditch is to seep water in the collection casting, in order to reduce groundwater pressure, gets rid of residue moisture content, makes the soil body and building can not soak into distortion because of outbreak and damages.Be widely used in the ground next part drainage works of the building projects such as building, traffic, water conservancy, work people miner, environment maintenance.For example:

The large tracts of land land reclamation engineerings such as airport, port and pier, stockyard for ease of carrying out the construction of place Soft Soils Consolidation in A, often need to immediately be laid the blind drainage system after hydraulic reclamation is completed, with acceleration surface layer draining and as reinforcing soft foundation horizontal drainage way.Various stations, square, heap ash factory generally need be with the blind drainage system as draining way forever.Speedway, highway, railway are laid on plastic blind-ditch on the roadbed and curb of speedway, highway, railway, the ponding that enters under the road surface can be collected discharge, accelerate surface drainage.Under express highway pavement, plastic blind-ditch is set, can accelerates drainage speed, avoid surface gathered water road pavement and vehicle to consist of infringement.Than multizone, the lower general french drain of laying of the both sides of highway and speedway center obstruct band is with dewatering in rainwater, underground infiltration.Grow at rock joint, zone of fracture is arranged, have when building tunnel or underground passage in the abundant soil layer of infiltration or underground water, normal easily outbreak seepage presentation, for this reason, being everlasting waterproofing course or the concrete-lined back of the body in work progress need, and there is aobvious rises on the stratum, lay plastic blind-ditch, consist of the network channel of collection row infiltration, give infiltration with road, in time drain and ooze ponding, can usefully dispose because concrete layout seam constuction joint is disposed to be owed or seepage presentation that the cause such as concrete lining outbreak crack is caused, and avoid underground infiltration to the corrosion of steel concrete.

But plastic blind-ditch commonly used easily results in blockage at present, and the drainability of french drain is constantly reduced, and normal drainage works is impacted.Therefore, be necessary the structure of plastic blind-ditch is improved, overcome the defective of prior art.

The utility model content

The purpose of this utility model is to provide a kind of plastic drainage French drain, to promote the drain function of french drain, strengthens anti-pressure ability, increases the service life.

The utility model is that the technical scheme that its technical problem of solution adopts is,

A kind of plastic drainage French drain includes filter core, and this filter core forms by plastic strip is stacking, each plastic strip random alignment, the mutual welding of the contact point of adjacent plastic strip consists of space network, has the gap between plastic strip, form the duct in filter core, this duct makes the inside and outside connection of filter core, and extraneous current infiltrate filter core from the duct inner, and discharge from the end of filter core, the filter core outside is provided with filter membrane, and this filter membrane is coated on cartridge surface, prevents that impurity from stopping up the duct;

In a novel embodiment of this use, filter membrane is made of non-woven geotextile;

In one embodiment, filter core is strip, and its cross section is circular;

In addition, filter core inside has tube chamber, and this tube chamber extends axially along filter core, and current come together in tube chamber after infiltrating filter core;

Further, tube chamber is provided with at least one, and the cross section of tube chamber is circular.

the utility model has the advantage of, this plastic drainage French drain is provided with non-woven geotextile in cartridge surface, impurity filters to external world, prevent that in process that current infiltrate, the duct to filter core results in blockage, and the cross section of filter core is rounded, its inside also is provided with circular tube chamber, when reducing the production material, strengthened the compressive property of whole filter core, the drainability of filter core is got a promotion, be conducive in time drain infiltration, this weeper drain has overcome the defective of traditional french drain, has the appearance percent opening high, catchmenting property is good, drainage is good, crushing resistance is strong, good endurance, lightweight advantage, constructability, constructor's labour intensity is greatly reduced, high efficiency.

Description of drawings

Fig. 1 is the structural representation of the plastic drainage French drain that the utility model proposes.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.

As shown in Figure 1, the plastic drainage French drain that the utility model proposes includes filter core 1, filter core 1 forms by plastic strip 2 is stacking, plastic strip 2 random alignment, the mutual welding of the contact point of adjacent plastic strip 2, consist of space network, has the gap between plastic strip 2, form duct 3 in filter core 1, this duct 3 makes that filter core 1 is inside and outside to be communicated with, and extraneous current infiltrate filter core 1 inside from duct 3, and discharge from the end of filter core 1, filter core 1 outside is provided with filter membrane 4, and filter membrane 4 is coated on filter core 1 surface, prevents that impurity from stopping up duct 3;

In the present embodiment, filter membrane 4 is made of non-woven geotextile; Filter core 1 is strip, and its cross section is circular; Filter core 1 inside has tube chamber 5, and tube chamber 5 extends axially along filter core 1, and current come together in tube chamber 5 after infiltrating filter core 1; Tube chamber 5 is provided with one, and the cross section of tube chamber 5 is circular.

this plastic drainage French drain is provided with non-woven geotextile in cartridge surface, impurity filters to external world, prevent that in process that current infiltrate, the duct to filter core results in blockage, and the cross section of filter core is rounded, its inside also is provided with circular tube chamber, when reducing the production material, strengthened the compressive property of whole filter core, the drainability of filter core is got a promotion, be conducive in time drain infiltration, this weeper drain has overcome the defective of traditional french drain, has the appearance percent opening high, catchmenting property is good, drainage is good, crushing resistance is strong, good endurance, lightweight advantage, constructability, constructor's labour intensity is greatly reduced, high efficiency.
