Description

A kind of nursery stock weeper drain

Technical field

The utility model relates to gardens technical field of drainage, in particular to a kind of nursery stock weeper drain.

Background technique

Nursery stock weeper drain is called underdrain, is a kind of subdrainage channel, to exclude underground water, lowering of watertable. It is commonly referred to as the coarse materials such as the broken, gravel of filling being arranged in roadbed or ground and spreads with the draining of inverted filter, intercepts water secretly Ditch.

As shown in figure 4, the construction method of nursery stock weeper drain in the prior art is as follows, irrigation canals and ditches 1 are first excavated in soil layer, The two sides and bottom of irrigation canals and ditches 1 are equipped with cement layer 11.Then pipeline 2 is embedded in inside irrigation canals and ditches 1, pipeline 2 and 1 bottom of irrigation canals and ditches are stayed There is certain distance, soil is backfilling into formation backfill 12 in irrigation canals and ditches 1.Pipeline 2 includes porous tube body 22 and is sheathed on porous Filter layer 24 outside tube body 22.When draining, entered in porous tube body 22 after the filtering that the water in soil passes through filter layer 24 Then portion is discharged by porous tube body 22.

It is in place of the deficiencies in the prior art, when the ponding in irrigation canals and ditches is more than porous bottom, water can be steadily It is discharged by porous tube body, and enters the intracorporal water of antipriming pipe from the hole at the top of porous tube body, porous tube body bottom can be passed through The hole in portion flows out, and causes drainage efficiency low.

Utility model content

The purpose of the utility model is to provide a kind of nursery stock weeper drains to have by the way that inner tube is arranged outside antipriming pipe body The advantages of being improved drainage effect.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of nursery stock weeper drain, the pipeline including irrigation canals and ditches and inside the irrigation canals and ditches, the pipeline includes inner tube, institute It states and is successively arranged with porous tube body and the first filter layer outside inner tube；Side in said inner tube far from trench bottom offers more A water-permeable passage.

By adopting the above technical scheme, the water entered in soil layer enters porous tube body by the filtering of the first filter layer In, then it is discharged by inner tube.Since the side of inner tube upward offers water-permeable passage, and side directed downwardly is closing setting, It is more efficiently discharged by inner tube so the water energy of internal tube is enough, the water reduced in inner tube is flow back by bottom of inner tube Situation in soil layer occurs.

Further preferably are as follows: the water-permeable passage is rectangle setting, and is distributed in 1/2 section of inner tube far from trench bottom On face.

By adopting the above technical scheme, increase the area that inner tube can intake, improve effect of catchmenting.Meanwhile by water-permeable passage It is set on 1/2 section, it can be while effect be catchmented in raising, so that drainage effect can also be protected.

Further preferably are as follows: assisted drainage component is had additional on the pipeline；The assisted drainage component includes being located at pipe Draining bent plate outside road is formed with drainage channel, and the draining bent plate between the draining bent plate inner wall and pipeline outer wall It is fixed on the pipeline by connector；The draining bent plate is between pipeline and trench bottom.

By adopting the above technical scheme, expand the area for being able to carry out draining, to improve drainage effect.Secondly, pipeline Bottom receives the protection of draining bent plate, to extend the service life of pipeline.

Further preferably are as follows: the connector includes connecting rod and link block；The link block is embedded at said inner tube In tube wall, the both ends of the connecting rod are individually fixed on the draining bent plate inner wall and link block.

By adopting the above technical scheme, the bonding strength between enhancing draining bent plate and inner tube, to extend draining bent plate Service life.

Further preferably are as follows: the second filter layer is provided between draining bent plate and the pipeline, the pipeline is located at first In the space that filter layer and draining bent plate are surrounded.

By adopting the above technical scheme, the water entered in draining bent plate is filtered, to improve inside draining bent plate Smoothness, improve drainage effect.

Further preferably are as follows: force bearing plate is had additional on the draining bent plate, the force bearing plate is on the outer wall of draining bent plate It is symmetrically arranged with two pieces.

By adopting the above technical scheme, in use, force bearing plate is supported in soil layer, support is played to draining bent plate and pipeline and is made With, thus reduce directly act on draining bent plate and pipeline on active force, and then extend pipeline and drain bent plate use the longevity Life.

Further preferably are as follows: the two sides of second filter layer are individually fixed on two pieces of force bearing plates.

By adopting the above technical scheme, it improves the second filter layer and drains the bonding strength between bent plate, reduce the two separation The case where causing filter effect to reduce appearance.

Further preferably are as follows: have additional reinforcing floor between the force bearing plate and the outer wall for draining bent plate.

By adopting the above technical scheme, the connection between enhancing draining bent plate and force bearing plate improves force bearing plate to draining The support effect of bent plate and pipeline.

Further preferably are as follows: the floor of reinforcing is arranged towards the bottom of the irrigation canals and ditches.

By adopting the above technical scheme, since the pressure that plate body is able to bear is greater than pulling force, support plate is fixed on reinforcing floor On can give under the effect of gravity reinforce one compressive pre-stress of floor, thus improve reinforce floor tension when tolerance range, into And extend the service life of draining bent plate.

In conclusion the utility model has the following beneficial effects: by the way that open-topped inner tube is arranged, so that needing to arrange Water out is discharged by inner tube, has the advantages that improve drainage effect.
