Description
Technical field
The utility model relates to a kind of dam body seepage structure, and it belongs to antiseepage dam structure class.
Background technology
For the dam body in places such as reservoir, refuse landfill, can take the geomembrane anti-seepage measure mostly now, so-called geomembrane anti-seepage measure is meant lays one deck geomembrane on dam body; The geomembrane that is made like thermoplastic resin material-polyvinyl resin; Shown in accompanying drawing 1, accompanying drawing 2, such seepage control project, excessive in order to prevent the film downforce; Generally all can on dam facing, lay one deck drainage layer; Lay geomembrane on the said drainage layer, laterally lay some earial drainage ditches by certain spacing under the said drainage layer, to discharge geomembrane infiltration down.The problem that prior art exists is, the earial drainage ditch that is provided with like this is owing to be the level trend; Usually find that in actual engineering a large amount of infiltrations accumulates in the earial drainage ditch, the earial drainage ditch of level trend also freely and does not usually stop up owing to current simultaneously, and the situation of overflowing; Cause near the dam body of catch-drain to be in for a long time under the state of bubble; Make dam body soft, moreover in the prior art, the technological means that situation about geomembrane not being seeped water is down assessed; According to the above, obviously prior art has further improved necessity.
Summary of the invention
The purpose of the utility model is to provide a kind of dam body seepage structure, to overcome the problem that prior art exists.
A kind of dam body seepage structure of the utility model comprises dam body, is equipped with the drainage layer on the dam facing of said dam body; Be equipped with geomembrane on the said drainage layer; Offer catch-drain on the dam facing of said dam body, it is characterized in that, said catch-drain is vertically laid; And the catch-drain of said vertical laying is separated into several longitudinal regions with said drainage layer, and adjacent two drainage layers form longitudinal separation.
This dam body seepage structure of the utility model because said catch-drain vertically lays, has been utilized the difference in height of dam body dam crest at the bottom of the dam well; Solve the problem of catch-drain impeded drainage, thereby also solved catch-drain ponding and blocking problem, utilized the catch-drain of vertically laying; The drainage layer is separated into several longitudinal regions; Help preventing that the bigger infiltration in a zone from occurring to the situation of whole drainage layer dispersed, according to the above, obviously the purpose of the utility model is achieved.
As further improvement; Said geomembrane is vertically laid; The catch-drain of said vertical laying is between adjacent two geomembranes; Film supporting member across adjacent two drainage layers is set between the longitudinal separation of said adjacent two drainage layers, and the handing-over side lap of adjacent two geomembranes of said vertical laying is on described film supporting member.Be provided with like this, film supporting member capable of using will have in promoting reliability and the structural strength that geomembrane connects as the connection auxiliary tool of adjacent two geomembranes.
As further improvement; Said dam body comprises the gallery in the dam body; On the lower position of said geomembrane a horizontal catch basin is set, said horizontal catch basin is communicated with longitudinal trench, is connected with an aqueduct on the said horizontal catch basin at least; Said aqueduct passes dam body and is connected to gallery, and said aqueduct is positioned at gallery one side and is provided with the water flow measurement device.The benefit that is provided with like this is and can confirms infiltration situation under the geomembrane through effective metering of flowing water that aqueduct is discharged, so that the operating condition of grasp geomembrane.
As further improvement; The lower side dam body of said horizontal catch basin is provided with anchorage block, and said geomembrane covers said horizontal catch basin, and the lower side of said geomembrane is anchored on the anchorage block; The mode that so horizontal catch basin is isolated from the outside is comparatively simple, is convenient to construction.
Description of drawings
Fig. 1 is the dam body seepage earial drainage ditch horizontally set structural representation of prior art.
Fig. 2 is that enlarged drawing is looked on the left side that the A part of Fig. 1 has added behind drainage layer and the geomembrane.
Fig. 3 is a kind of dam body seepage structural representation of the utility model preferred embodiment.
In respectively scheming, 1 is that dam body, 101 is that dam facing, 2 is that geomembrane, 3 is that drainage layer, 4 is that catch-drain, 5 is that horizontal catch basin, 6 is that anchorage block, 7 is that gallery, 8 is that aqueduct, 9 is the film supporting member.
The specific embodiment
A kind of dam body seepage structure and the accompanying drawing thereof that below will combine the utility model preferred embodiment to provide are described further the utility model.
A kind of dam body seepage structure that the utility model preferred embodiment provides shown in accompanying drawing 3, comprises dam body 1; Be equipped with drainage layer 3 on the dam facing 101 of said dam body 1; Be equipped with geomembrane 2 on the said drainage layer 3,101 offer catch-drain 4 on the dam facing of said dam body 1, it is characterized in that said catch-drain 4 vertically lays; And the catch-drain 4 of said vertical laying is separated into several longitudinal regions with said drainage layer 3, and 3 on adjacent two drainage layer forms longitudinal separation.
In this preferred embodiment; Said geomembrane 2 is vertically laid; The catch-drain 4 of said vertical laying is between adjacent two geomembranes 2; Film supporting member 9 across adjacent two drainage layers is set between the longitudinal separation of said adjacent two drainage layers 3, and the handing-over side lap of adjacent two geomembranes 2 is on described film supporting member 9.
