Abstract
The utility model discloses a seam face drainage structures of big dam structure seam or induced seam, include structural joint or induced seam (3) and arrange the structural joint in or induced stagnant water (2) of stitching on (3), stagnant water (2) later are provided with drain pipe (1), and on structural joint or induced seam (3) seam face were arranged in to the water inlet of drain pipe (1), its outlet was drawn forth to near escape canal. The utility model discloses utilizing the drain pipe to form a drainage channel on the seam face of structural joint or induced seam, forming the seepage passageway in case the structural joint stagnant water loses efficacy, the drain pipe can draw escape canal in row seepage rivers to the dam body effectively, prevents that percolating water from getting into inside the dam body to reach the inside consolidation of effective reduction dam body, guarantee structure safety and normal use.
Description
Technical field
The utility model relates to the seam face discharge structure of a kind of dam structure seam or attractive joint, belongs to dam engineering technical field.
Background technology
Because of the needs of structural configuration and dam deformation, dam all needs when structure design to consider to stitch at vertical axis of dam direction arrangement, whole dam body is divided into relatively independent individuality, simultaneously for preventing storehouse water from leaking into dam body along structural joint, increase dam body osmotic pressure, thus affect structural safety and normal use, structural joint process is considered below water level, arrange 1 ~ 3 road water-stopping structure along structural joint face.But, because construction process control is not strict, the water slop failure at structural joint place can be caused, make structural joint directly become penetrating passage, affect the normal use of dam body.
Utility model content
The purpose of this utility model is: provide a kind of structure simple, easy construction, and after dam structure seam water slop failure, also can play the dam structure seam of good seam face drainage and step-down effect or the seam face discharge structure of attractive joint, to overcome the deficiencies in the prior art.
The technical solution of the utility model: the seam face discharge structure of a kind of dam structure seam or attractive joint, the sealing comprising structural joint or attractive joint and be placed on structural joint or attractive joint, gutter is provided with after described sealing, the water inlet of gutter is placed on structural joint or attractive joint seam face, and its outfall leads to neighbouring gutter.
Described sealing (2) arranges 3 roads at the distance interval 0.5m of distance dam upstream face (4) 1m.
Described sealing (2) adopts sheet rubber or copper sheet to make.
Described gutter is plastics blind pipe, porous floral tube or sand-free concrete tube.
Owing to adopting technique scheme, the utility model has the advantage of: the utility model utilizes gutter to form a drainage channel on the seam face of structural joint or attractive joint, once structural joint water slop failure forms leakage passage, gutter can flow to dam body internal drainage ditch by ejectment percolating water effectively, prevent percolating water from entering dam body inside, thus reach the effectively inner osmotic pressure of reduction dam body, ensure structural safety and normal use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: 1-gutter, 2-sealing, 3-structural joint or attractive joint, 4-dam upstream face.
Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The structural representation of the seam face discharge structure of a kind of dam structure seam of the present utility model or attractive joint as shown in Figure 1, the sealing 2 comprising structural joint or attractive joint 3 and be placed on structural joint or attractive joint 3, be provided with gutter 1 after described sealing 2, described gutter 1 is plastics blind pipe; The water inlet of gutter 1 is placed on structural joint or attractive joint 3 seam face, and its outfall leads to neighbouring gutter.Described sealing 2 adopts sheet rubber or copper sheet to make, and arranges 3 roads at the distance interval 0.5m of distance dam upstream face 1m.
Claims (4)
1. the seam face discharge structure of a dam structure seam or attractive joint, the sealing (2) comprising structural joint or attractive joint (3) and be placed on structural joint or attractive joint (3), it is characterized in that: after described sealing (2), be provided with gutter (1), the water inlet of gutter (1) is placed on structural joint (3) seam face, and its outfall leads to neighbouring gutter.
2. the seam face discharge structure of dam structure seam according to claim 1 or attractive joint, is characterized in that: described sealing (2) arranges 3 roads at the distance interval 0.5m of distance dam upstream face (4) 1m.
3. the seam face discharge structure of dam structure seam according to claim 2 or attractive joint, is characterized in that: described sealing (2) adopts sheet rubber or copper sheet to make.
4. the seam face discharge structure of dam structure according to claim 1 seam or attractive joint, is characterized in that: described gutter (1) is plastics blind pipe, porous floral tube or sand-free concrete tube.
