Abstract
The utility model discloses a geomembrane stagnant water structure of setting on wave wall, including PVC geomembrane, geotechnological cloth and stainless steel apron. The PVC geomembrane and the geotextile are fixed on the upstream surface structural joint of the concrete wave wall through the rubber anchoring strip and the anchoring bolt, and the stainless steel cover plate anchor is fixed on the top structural joint of the wave wall through the anchoring bolt. The utility model is suitable for a wave wall is prevented on hydraulic structures such as dam, reservoir, channel, dykes and dams, the stagnant water requirement of wave wall can effectively be satisfied, and compares with the geomembrane stagnant water structure of tradition setting on wave wall and can practice thrift engineering time and cost.
Description
Technical Field
The utility model relates to a water conservancy, electric power technical field, concretely relates to geomembrane stagnant water structure of setting on wave wall mainly is applicable to the wave wall of preventing on hydraulic buildings such as dam, reservoir, channel, dykes and dams.
Background
The wave wall is a wall body arranged at the front edge of the water retaining of the dam crest for preventing waves from turning over the dam crest. It is used in dam, reservoir, canal and dam to prevent wave, flood and water. The stable, firm and watertight wave wall can properly reduce the super height of the dam and save the dam construction amount. The height of the wave wall is determined according to calculation results such as surge height and the like, and the method is generally suitable for not blocking the sight of people. The wave wall can be cast in place or prefabricated. The concrete wave wall structure must be abutted tightly in order to prevent water leakage at the joint, usually a groove structure is required to be arranged and special water-stopping materials are filled, so that the construction difficulty exists, and the concrete wave wall structure is not economical and applicable. What kind of connection structure of adoption both can guarantee structure seam position stagnant water, can accomplish simple and practical again, construction convenience, become a design engineer's a big difficult point.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: aiming at the problems, the geomembrane water stop structure arranged on the wave wall is provided, and is mainly suitable for the wave wall on structures such as dams, reservoirs, channels, dams and the like. The structure effectively meets the water stop requirement of the wave wall, and saves the construction time and cost. The utility model adopts the technical proposal that:
a geomembrane water stop structure arranged on a wave wall comprises a PVC geomembrane, geotextile and a stainless steel cover plate; the PVC geomembrane and the geotextile are fixed on the upstream surface structural seam of the concrete wave wall through the rubber anchoring strip and the anchoring bolt; the stainless steel cover plate anchor is fixed on the structural joint at the top of the wave wall through the anchor bolt, and the functions of water retaining and protecting are achieved.
Furthermore, the geotechnical cloth is arranged on the outer side of the PVC geomembrane, so that the geomembrane can be prevented from being aged after being exposed outdoors for a long time.
Further, the rubber anchoring strip is anchored outside the geotextile by the anchoring bolt for fixing the geotextile and the PVC geomembrane and preventing the geotextile from being damaged by the anchoring bolt.
Furthermore, the edge of the water-facing side of the wave wall of the stainless steel cover plate exceeds the top of the wave wall, the part of the stainless steel cover plate exceeding the top of the wave wall is bent towards the water-facing side of the wave wall, covers the outer side of the rubber anchoring strip and is anchored by the anchoring bolt, and water is prevented from permeating from the joint of the top of the wave wall, the PVC geomembrane and the geotextile.
Due to the adoption of the scheme of the utility model, the structure is simple, the water stop of the structural joint can be effectively ensured, the construction speed is high, and the engineering cost is saved; the utility model has higher tensile strength, cracking resistance, aging resistance and ductility, and can reduce the influence of dislocation deformation and long-term exposure outdoors on an anti-seepage system; the top end structure seam adopts the stainless steel cover plate to reduce the influence of rainfall and surge on the backward flow of the structure seam.
Description of the drawings:
fig. 1 is a schematic view of an embodiment of the present invention.
Fig. 2 is a schematic cross-sectional view of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to the attached drawings, the utility model provides a pair of geomembrane stagnant water structure of setting on wave wall, including PVC geomembrane, geotechnological cloth and stainless steel apron.
As shown in fig. 1 and 2, the PVC geomembrane 1 and the geotextile 2 are disposed outside the upstream side structural seam 3 of the wave wall and are covered by the rubber anchoring strips 4 on both sides of the structural seam 3. The geotextile 2 is arranged on the outer side of the PVC geomembrane 1 and is used for preventing the geomembrane from being exposed outdoors for a long time to age. The anchoring bolts 5 anchor the rubber anchoring strips 4 covering the PVC geomembrane 1 and the geotextile 2 at two sides of the structural joint 3, so as to ensure the water stop at the position of the structural joint 3. The rubber anchoring strip 4 prevents the geotextile from being damaged by the anchoring bolt.
The stainless steel cover plate 6 is anchored at the upper part of the structural joint 3 of the wave wall through the anchor bolt 5, plays a role in retaining water and protecting, and can reduce the influence of rainfall and surge on the backward flow of the structural joint. Meanwhile, the edge of the water-facing side of the wave wall of the stainless steel cover plate 6 exceeds the top of the wave wall, the part of the stainless steel cover plate exceeding the top of the wave wall is bent towards the water-facing side of the wave wall, covers the outer side of the rubber anchoring strip 4 and is anchored by the anchoring bolt 4, and water is prevented from permeating from the joint of the top of the wave wall and the PVC geomembrane 1 and the geotextile 2.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art can change, add or replace the above examples within the scope of the present invention.
