Abstract

The utility model relates to a channel geomembrane barrier layer, including stacking gradually the geotechnological drainage pipeline networks of the prefabrication of laying, the geotechnique of lower floor straw mats, geomembrane, upper geotechnological straw mats, precast concrete board. The utility model provides a channel geomembrane barrier layer adopts and to arrange in geomembrane both sides that the mode of geotechnological straw mats and geotechnological drainage pipeline networks replaces traditional cushion material, solves the big problem of the cushion material compaction degree of difficulty, reduces geomembrane prevention of seepage investment, has improved its efficiency of construction simultaneously, can satisfy practical application's needs well.

Description

A kind of channel geomembrane anti-seepage layer
Technical field
This utility model belongs to water conservancy project building technical field, and in particular to a kind of channel geomembrane anti-seepage layer.
Background technology
In Hydraulic and Hydro-Power Engineering, geomembrane is had been widely used in engineering practice as impervious body.It is anti-in channel In oozing, geomembrane also serves as impervious body and is widely used, traditional geomembrane anti-seepage structure, in order to protect geomembrane not by two Kerbstone material is pierced through, while ensureing geomembrane bottom draining, it is often necessary to arrange bedding material in geomembrane both sides, bedding material is matched somebody with somebody to level There is higher requirement, while causing to damage to geomembrane in order to avoid bedding material is rolled, geomembrane both sides bedding material is generally required Manual compaction, low construction efficiency, compactness are also difficult to ensure that.
Utility model content
For above-mentioned problems of the prior art, the purpose of this utility model is to provide one kind to avoid the occurrence of State the channel geomembrane anti-seepage layer of technological deficiency.
In order to realize above-mentioned utility model purpose, the technical scheme that this utility model is provided is as follows:
A kind of channel geomembrane anti-seepage layer, including prefabricated soil engineering drainage pipe network 4, the lower floor geotechnique straw mats for stacking gradually laying 6th, geomembrane 3, upper strata geotechnique straw mats 2, precast slab 1.
Further, 6 thickness of lower floor's geotechnique's straw mats is 2cm.
Further, 2 thickness of upper strata geotechnique's straw mats is 1cm.
Further, the mesh size of the soil engineering drainage pipe network 4 is 2m × 2m.
Further, the thickness of the precast slab 1 is 15cm.
The channel geomembrane anti-seepage layer that this utility model is provided, arranges geotechnological straw mats and geotechnique row using in geomembrane both sides The mode of grid replaces traditional bedding material, solves the problems, such as that bedding material compacting difficulty is big, reduces geomembrane anti-seepage investment, together When improve its efficiency of construction, the needs of practical application can be met well.
Description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure, 1- precast slabs, 2- upper stratas geotechnique's straw mats, 3- geomembranes, 4- soil engineering drainage pipe networks, 5- channels side Slope, 6- lower floors geotechnique's straw mats.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and specifically Embodiment is described further to this utility model.It should be appreciated that specific embodiment described herein is only to explain this reality With new, it is not used to limit this utility model.Based on the embodiment in this utility model, those of ordinary skill in the art are not having There is the every other embodiment obtained under the premise of making creative work, belong to the scope of this utility model protection.
As shown in figure 1, a kind of channel geomembrane anti-seepage layer, including stack gradually laying prefabricated soil engineering drainage pipe network 4, under The geotechnological straw mats 6 of layer, geomembrane 3, upper strata geotechnique's straw mats 2, precast slab 1.Prefabricated soil engineering drainage pipe network 4 is laid on channel side On slope 5, lower floor's geotechnique's straw mats 6 are laid on prefabricated soil engineering drainage pipe network 4, and geomembrane 3 is laid on lower floor's geotechnique's straw mats 6, on The geotechnological straw mats 2 of layer are laid on geomembrane 3, and precast slab 1 is laid on the geotechnique's straw mats 2 of upper strata.
When this utility model is laid, channel excavation is carried out first, the channel side slopes 5 that excavation is completed are carried out necessary flat Whole, the difference that rises and falls is not more than 5cm, while avoiding lag gravel from causing to wear out to geomembrane surely bad, is easy to the laying of follow-up geomembrane. Earthwork drainage pipe net 4 is laid on channel side slopes 5 after smooth, it is ensured that the water energy that geomembrane oozes enough is drained in time, soil engineering drainage The mesh size of pipe network 4 is 2m × 2m.In 4 top of soil engineering drainage pipe network laying lower floor geotechnique's straw mats 6, lower floor's geotechnique's straw mats 6 are thick Degree is preferably 2cm.
Geomembrane 3 is laid on lower floor's geotechnique's straw mats 6, while checking to geomembrane 3, it is to avoid there is bad point.Geomembrane 3 Composite geo-membrane must not be adopted, it is to avoid composite geo-membrane is difficult to the shortcoming for checking.
In 3 top of geomembrane laying upper strata geotechnique's straw mats 2, upper strata geotechnique straw mats 2 thickness can be with thin, and preferred thickness is 1cm.Upper strata geotechnique's straw mats 2 can prevent precast concrete protection board 1 from causing friction destruction to geomembrane 3.
If the channel gradient is steeper, appropriate anchoring is carried out to lower floor's geotechnique's straw mats 6 and geomembrane 3 if necessary.
Precast slab 1 is laid on the geotechnique's straw mats 2 of upper strata as protection, to avoid geomembrane 3 from shining because of ultraviolet Penetrating causes service life to reduce, and the thickness of precast slab 1 is not preferably less than 15cm, preferably 15cm.
The channel geomembrane anti-seepage layer that this utility model is provided, is substituted by the way of geotechnological straw mats and soil engineering drainage pipe network Traditional geomembrane bedding material and Transition Materials, can increase substantially the seepage capability of geomembrane, shorten the engineering time, while keeping away Geomembrane bedding material construction compacting is exempted from easily geomembrane to be caused to pierce through the problem damaged, has imitated with larger economic society Benefit, can meet the needs of practical application well.
Embodiment described above only expresses embodiment of the present utility model, and its description is more concrete and detailed, but and Therefore the restriction to this utility model the scope of the claims can not be interpreted as.It should be pointed out that for the ordinary skill of this area For personnel, without departing from the concept of the premise utility, some deformations and improvement can also be made, these belong to this The protection domain of utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
