Abstract

The utility model provides a special washable pipe for highway drainage sewers, which consists of an outer drainage pipe, an inner drainage pipe and a water-permeable material layer. A plurality of drain holes are uniformly distributed on the walls of the outer drainage pipe and the inner drainage pipe, and the water-permeable material layer is arranged in a sandwich layer between the outer drainage pipe and the inner drainage pipe. By the aid of the special washable pipe for the highway drainage sewers, the problem of blockage of existing highway drainage sewers is solved, so that drainage of highways is smooth, running safety of vehicles is guaranteed, and the service lives of the highways are prolonged. In addition, the special washable pipe for the highway drainage sewers has the advantages of easiness in construction, economization of construction cost and convenience in maintenance.

Description

Formula highway drainage french drain dedicated pipe capable of washing

Technical field

The utility model relates to the technical field of aspect, gutter, particularly a kind of formula highway drainage french drain dedicated pipe capable of washing.

Background technology

China's south rainwater is more, and the highway drainage facility is perfect inadequately, and many highways not only influence traffic because purt mud phenomenon does not freely often appear in subgrade drainage, also have a strong impact on the application life of highway.In the prior art; Usually adopt the way of setting up weeper drain to solve; Its method is draining, the covered conduit that intercepts water that coarse material such as filling rubble, gravel is set in roadbed or ground and is aided with inverted filter (have bury underground water-permeable pipe), and general weeper drain has rubble french drain, porous concrete french drain and plastics french drain etc. according to the filler difference.Because these weeper drains are through use after a while after, to have no idea again to clean because of mud stops up through regular meeting and lose drain function, this is the weak point of prior art existence just.

The utility model content

The purpose of the utility model is to solve existing highway maintenance weeper drain and the mud blocking problem often occurs, and a kind of formula highway drainage french drain dedicated pipe capable of washing is provided, and it can clean mud in the french drain, guarantees the blind drainage function.

Above-mentioned task realizes by this way: a kind of formula highway drainage french drain dedicated pipe capable of washing; Form by outer gutter, internal drainage pipe and seepy material layer; Evenly have several drain holes on the tube wall of described outer gutter and internal drainage pipe, the seepy material layer is arranged in the interlayer between outer gutter and the internal drainage pipe.

In such scheme, described outer gutter and internal drainage pipe are with there being the plastic pipe of certain compression strength to process, and the most handy high density polyethylene (HDPE) (HDPE) pipe is processed.

In such scheme, described seepy material can adopt materials such as geotextiles, sponge and cotton, but the most handy geotextiles, convenient construction.

The utility model is to use like this: at first, the desired location that on the highway embankment side slope, laterally punches, the outer gutter with this weeper drain inserts in the hole then, and the internal drainage pipe that will wrap up seepy material again inserts in the outer gutter just can.When rainy, rainwater is seeped on the outer gutter of this weeper drain through highway pavement surface layer and basic unit, gets into the seepy material layer through drain hole and gets into discharge outward in the internal drainage pipe through the drain hole of internal drainage pipe again.When after using after a while, during the more mud of deposition, can extract internal drainage pipe and seepy material out in the pipe, seepy material is cleaned or changes, reload again in the gutter, guaranteed the drain function of weeper drain.

In sum, the utility model can solve the blockage problem that the existing highway weeper drain exists always effectively, makes highway drainage freely suitable, has guaranteed the driving safety of vehicle, has prolonged the application life of highway.In addition, the utility model also has easy construction, saves construction cost and is convenient to advantage such as maintenance.

Fig. 2 is along the cutaway view Amplified image of A-A line among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the structure of the utility model is done further to describe.

See figures.1.and.2; A kind of formula highway drainage french drain dedicated pipe capable of washing; It is characterized in that forming by outer gutter 1, internal drainage pipe 2 and seepy material layer 3; Evenly have several drain holes 4 on the tube wall of described outer gutter 1 and internal drainage pipe 2, seepy material layer 3 is arranged in the interlayer between outer gutter 1 and the internal drainage pipe 2.

The utility model is when implementing, and outer gutter 1 all uses high density polyethylene (HDPE) (HDPE) pipe to process with internal drainage pipe 2, and seepy material layer 3 adopts geotextiles.
