Abstract

The utility model relates to a structure for embedding a drain pipe in concrete. According to the structure, the drain pipe in the concrete is good in drainage performance, high in reliability requirement, and durable. According to the technical scheme, the structure comprises a concrete structure and a foundation or a side slope adjacently connected with the concrete structure, and the drain pipe is arranged inside the concrete structure. The structure is characterized in that the drain pipe is a plastic drainage blind pipe, wherein the interior of the drainage blind pipe is in a three-dimensional porous shape; a pipe orifice I in one end of the drainage blind pipe is flush with the surface of the concrete structure; a pipe orifice II in the other end of the drainage blind pipe slightly protrudes from the concrete structure and penetrates into the side, where the foundation or the side slope is located, of the concrete structure; the pipe orifice II is wrapped with two layers of geotechnical cloth. The structure for embedding the drain pipe in the concrete is applicable to water diversion and water drainage structure construction of hydraulic structures.

Description

A kind of concrete internal drainage pipe bury structure underground

Technical field

The utility model relates to a kind of structure of burying underground of concrete internal drainage pipe, is applicable to water guide, the discharge structure construction of hydraulic structure.

Background technology

For meeting the requirements such as the draining of hydraulic structure collection, water guide, assurance structural safety, in the concrete structure of being everlasting in engineering, gutter is set.What in general, more generally adopt is pre-buried pvc pipe or the method such as hole in concrete in concrete.

The problem of doing is like this, after operation after a while, concrete surface (as positions such as the permeable backplate surfaces of absorption basin) some dirts etc. that may deposit, these things silting gutter gradually, and can be deep into gutter inside, therefore cleaning is got up comparatively difficult.In addition, the geotextiles of basis or side slope side parcel may be damaged in the time of construction or in During Process of Long-term Operation.Once geotextiles breakage, the native stone fine grained in basis or side slope side will enter gutter smoothly, causes seepage failure.

For gutter is set in concrete, how to consider to adopt the not only method of convenient but also simple possible, overcome shortcoming or the deficiency of in concrete, burying pvc pipe underground, be the Concrete Structure Design with construction in an important technology.

Summary of the invention

The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide that a kind of drainage performance is good, reliability requirement is high and the concrete internal drainage pipe of good endurance bury structure underground.

The technical scheme that the utility model adopts is: the basis or the side slope that have concrete structure and be adjacent, in this concrete structure, gutter is set, it is characterized in that: described gutter is that inside is the cavernous plastic draining blind pipe of 3 D stereo, this draining blind pipe one end mouth of pipe I flushes with concrete structural surface, other end mouth of pipe II slightly stretch out concrete structure and go deep into basis or side slope side in, the two-layer geotextiles of mouth of pipe II coated outside.

The outer wall parcel diaphragm of described plastic draining blind pipe.

Described plastic draining blind pipe is after thermoplastic synthetic resin heating and melting, to squeeze out fibre by nozzle to be formed by stacking, and its phase contact cementing is become to 3 D stereo porous shape.

Described plastic draining blind pipe caliber is between 80 ~ 300mm.

The beneficial effects of the utility model are: 1, the utility model adopts solid plastic draining blind pipe to replace pvc pipe, this pipe is a kind of macromolecular material, there is the advantages such as percent opening is high, compressive property is strong, displacement is large, good endurance, and can be made into various sectional forms, belong to environment-friendly materials, long service life, easy construction.2, the tridimensional network in plastic draining blind pipe can stop that dirt enters, even if enter, also can only silting top layer, and the later stage clears up convenient.3, when after long use, the geotextiles of basis or side slope side parcel may be damaged, due to the support of tridimensional network in gutter, damaged face generally can further not expand, native stone fine grained in basis or side slope side is just difficult for entering gutter, thereby the process of basis, side slope seepage failure is stablized or delayed to assurance infiltration structure.

Fig. 2 is that the a-a of Fig. 1 is to sectional drawing.

Fig. 3 is that the b-b of Fig. 1 is to sectional drawing.

The specific embodiment

As shown in Figure 1, the present embodiment is a kind of structure of burying underground of concrete internal drainage pipe, this is buried structure underground and has concrete structure 5 and basis or side slope side 6 with concrete structure 5 adjacent layouts, in concrete structure 5, bury gutter underground, as Fig. 2, shown in 3, described gutter is plastic draining blind pipe 2, its inside is tridimensional network, to be formed by stacking by squeezing out fibre by nozzle after thermoplastic synthetic resin heating and melting, and its phase contact cementing is formed to the shape of 3 D stereo porous, this shape can stop entering of dirt, even if dirt has entered, also can only silting top layer, later stage clears up very convenient.This draining blind pipe one end mouth of pipe I1 is pre-buried to be flushed with concrete surface 5-1; and give temporary protection at materials such as mouth of pipe I1 covering geotextiles; prevent from accidentally concrete slurry being fallen in pipe in the time of concreting structure 5; draining blind pipe other end mouth of pipe II7 stretches out concrete structure 5 slightly; go deep in basis or side slope side 6; for preventing that the interior native stone granulate of basis or side slope side 6 from entering in draining blind pipe, by two-layer mouth of pipe II7 coated outside geotextiles 4.

Described plastic draining blind pipe 2 calibers generally between 80-300mm, in the time of construction, prevent that concrete slurry from entering in pipe according to engine request, and at draining blind pipe pipe outer wrapping layer protecting film 3, this diaphragm 3 generally can be plastic sheeting.

The construction sequence of the present embodiment is as follows:

A, before concreting, by after plastic draining blind pipe 2 pipe outer wrapping layer of plastic film 3, be fixed, pre-buried;

B, flush with concrete surface 5-1 pre-buried one end mouth of pipe I1 of plastic draining blind pipe 2, other end mouth of pipe II7 is micro-be exposed to concrete structure 5 and go deep into basis or side slope side 6 in;

C, the mouth of pipe II7 of basis or side slope side 6 is wrapped up by two-layer geotextiles 4;

D, cover the material such as geotextiles at plastic draining blind pipe 2 mouth of pipe I1;

E, carry out concreting structure 5;

F, have after some strength until concrete structure 5, remove the overburden of mouth of pipe I1.
