Abstract

A kind of landfill yard guide french drain pipeline configuration, including the perforated pipe, metalling and direction earthwork grille being sequentially arranged from inside to outside, the perforated pipe includes pipe shaft, circumferentially and it is axially spaced to be provided with several through holes on pipe shaft, metalling is fixedly attached at the outer wall of perforated pipe, and direction earthwork grille is coated on the outer wall of metalling.The landfill yard guide french drain pipeline is embedded in landfill heap, the moisture filled in heap passes through direction earthwork grille, is then filtered through metalling, finally enter in perforated pipe and drain along perforated pipe, it is its work safety, smooth, while can be in prefabricated in workshop, so that improving it makes precision and quality.

Description

A kind of landfill yard guide french drain pipeline configuration

Technical field

French drain is the utility model is related to, more particularly to a kind of pipeline configuration for being used as guide french drain in landfill yard.

Background technology

The coarse materials such as the broken, gravel of filling set in french drain, i.e. roadbed or ground simultaneously spread with the draining of inverted filter, intercept water Underdrain, it is excluding underground water, lowering of watertable.

Existing french drain is formed generally by rubble is filled into the vertical hole in soil layer so that the water in soil layer Point penetrate into french drain, then these moisture are seeped into the drainage pipeline of soil layer bottom along under french drain and finally drain.This kind of french drain one Aspect needs scene filling rubble gravel, its production quality is difficult to be effectively ensured, and is on the other hand then that french drain is arranged vertically, Its drainability is poor.

The content of the invention

The utility model aims to provide that a kind of easy to make, guide ability is strong and the landfill yard guide french drain of service life length Pipeline configuration, to improve landfill yard drainability and reduce production cost.

Landfill yard guide french drain pipeline configuration described in the utility model, including be sequentially arranged from inside to outside perforated pipe, Metalling and direction earthwork grille, the perforated pipe include pipe shaft, circumferentially and are axially spaced to be provided with several on pipe shaft Through hole, metalling are fixedly attached at the outer wall of perforated pipe, and direction earthwork grille is coated on the outer wall of metalling.

Landfill yard guide french drain pipeline configuration described in the utility model, opens up logical on the perforated pipe pipe shaft of innermost layer Hole so that the moisture in landfill heap is easier to enter in perforated pipe, is then laid with metalling and double successively in the outside of perforated pipe To TGXG, its not only can with reinforcement structure intensity, avoid the stone in metalling from coming off, but also can prevent the rubbish of large volume Into and influence equipment work smoothness.The landfill yard guide french drain pipeline is embedded in landfill heap, fills the moisture in heap Through direction earthwork grille, then filtered through metalling, finally enter in perforated pipe and drain along perforated pipe, its work safety, It is smooth, while can be in prefabricated in workshop, so that improving it makes precision and quality.

Brief description of the drawings

Fig. 1 is the cross section structure schematic diagram of landfill yard guide french drain pipeline.

Fig. 2 is the structure diagram of perforated pipe.

Fig. 3 is the view that landfill yard guide french drain pipeline is embedded in landfill heap.

Fig. 4,5 be provided with geomembrane landfill yard guide french drain pipeline structure diagram.

Fig. 6 is the view that more landfill yard guide french drain pipelines are embedded in landfill heap.

Embodiment

A kind of landfill yard guide french drain pipeline configuration, including perforated pipe 1, the metalling 2 and double being sequentially arranged from inside to outside To TGXG 3, the perforated pipe 1 includes pipe shaft 4, circumferentially and is axially spaced to be provided with several through holes 5 on pipe shaft 4, Metalling 2 is fixedly attached at the outer wall of perforated pipe 1, and direction earthwork grille 3 is coated on the outer wall of metalling 2.

As shown in Figure 1, 2, through hole is opened up on the perforated pipe pipe shaft of innermost layer so that the moisture in landfill heap is easier to enter In perforated pipe, metalling and direction earthwork grille are then laid with successively in the outside of perforated pipe.Pipeline can be prefabricated, by it after being made It is embedded in landfill heap, the moisture produced in landfill heap, which can enter in pipeline, drains, it makes, and precision is high, quality is good, uses Long lifespan, and it is safe and reliable.Direction earthwork grille can use the grid of plastic production, its anti-corrosive properties is higher and cost is low It is honest and clean.

As seen in figures 3-6, the landfill yard guide french drain pipeline is obliquely embedded in landfill heap 9 so that moisture is more Add and quickly and easily drain along pipeline.In addition, landfill heap is oozed out into again in order to avoid entering the moisture in pipeline, tilt Geomembrane 6 is equipped between the bottom surface of the metalling 2 of setting and direction earthwork grille 3, as shown in figure 5, geomembrane is arranged at figure Between the metalling and direction earthwork grille of middle bottom so that moisture is more easily drained along pipeline, and can avoid moisture weight It is new to penetrate into landfill heap, so as to improve its task performance.In addition, because the height for filling heap is larger, and needed repeatedly during landfill Landfill waste, and pipeline of the bottom surface equipped with geomembrane is unfavorable for the entrance of lower section moisture, for this reason, more pipelines can be arranged at The different height position in heap is filled, as shown in fig. 6, thus improving the work efficiency of whole landfill heap.

Claims
