Abstract
The utility model discloses a structural joint between upstream middle face plates of a concrete face rockfill dam. The structural joint comprises concrete face plates (1), structural joint bodies (2) are arranged between adjacent concrete face plates (1), the width of each structural joint body is larger than 5mm, elastic materials are filled in each structural joint body, a top water stopping system (3) is arranged at the top o each structural joint body (2), and a bottom water stopping system (4) is positioned at the bottom of each structural joint body. The structural joint is of an elastic structure, is stable, solves the problem that when the concrete face rockfill dam runs, face plates are prone to be protruded and damaged due to the fact that a dam body deforms excessively along the dam axis direction, and has obvious economic and social benefits.
Description
Technical field
The utility model relates to the structural joint between the central panel of a kind of Concrete Face Rockfill Dam upstream, belongs to the Hydraulic and Hydro-Power Engineering technical field.
Background technology
In the Concrete Face Rockfill Dam engineering, usually can arrange improperly because of the central panel structural joint, behind engineering operation, because dam body generation STRESS VARIATION, cause taking place between the panel of upstream damaged, generally show as extruding and fracture and destroy two kinds of patterns.Steep along with the increase of dam body and two sides landform simultaneously, this kind destroys the more obvious of pattern performance.Therefore, rationally solving damaging problem between the central panel has become an important techniques difficult problem in Concrete Face Rockfill Dam design and the construction, and prior art still is not ideal enough.
Summary of the invention
The purpose of this utility model is, structural joint between the central panel of a kind of Concrete Face Rockfill Dam upstream is provided, it is wide that this structural joint is provided with certain seam, and the seam in pointing elastomeric material, can effectively solve the problem that extruding takes place and fracture and destroy between the panel, to overcome the deficiencies in the prior art.
For realizing the purpose of this utility model, the utility model has adopted such technical scheme: the structural joint between the central panel of Concrete Face Rockfill Dam of the present utility model upstream is to be provided with structural joint between adjacent concrete slab, the width of structural joint is greater than 5mm, filling elastic material in it.Elastomeric material is the material of common anti-extruding, requires to have decrement preferably.The top of structural joint arranges the top water-stopping system, and the bottom arranges the bottom water-stopping system.
Further, the width of structural joint is 6mm～100mm, also has to arrange from panel top to bottom to broaden, and determines according to project scale and actual checking computations.
Further, capping position setting " V " the type groove of structural joint.
Further, the structure formed by flexible and sticky stuff of top water-stopping system.The structure that the bottom water-stopping system is made up of copper sheet sealing and stickiness sealing material.Top and bottom water-stopping system arrange according to panel enrockment joint seal technical specification.
In addition, elastomeric material can be pitch China fir plate, plastic plate etc., and the modulus of elasticity of plank requires greater than 11000MPa, and the modulus of elasticity of plastic plate is greater than 2.0MPa;
Compared with prior art, it is wide that structural joint of the present utility model is provided with certain seam, and the seam in pointing elastomeric material, both can satisfy the dam body operation under the normal condition, can absorb the distortion that produces along axis of dam direction when two sides again when the middle part, riverbed is subjected to displacement simultaneously, it is damaged that the protection panel does not produce extruding; For guaranteeing the normal operation of this position water-stopping system, still be provided with top and bottom water-stopping system according to panel enrockment joint seal technical specification at elastic joint top and bottom simultaneously.So it is stable to plant elastic construction seam pattern, solved in the Concrete Face Rockfill Dam running because dam body is excessive and then produce the damaged situation of panel extruding along the distortion of axis of dam direction, have remarkable economic efficiency and social benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-concrete slab, 2-structural joint, 3-top water-stopping system, 4-bottom water-stopping system.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
See Fig. 1, structural joint between the central panel of the utility model Concrete Face Rockfill Dam upstream, comprise concrete slab 1, be provided with structural joint 2 between the adjacent concrete slab 1, filled elastomeric material in the structural joint 2, the top of structural joint 2 arranges top water-stopping system 3, and the bottom arranges bottom water-stopping system 4.Capping position setting " V " the type groove of structural joint 2.
The utility model is implemented according to following steps:
The first step is prepared material, and structural meterials, top and bottom seam sealing material in the structural joint 2 are carried out an acceptance inspection, and the material of acceptance(check) can be used as construction application.
Second step was transported to the job site in order with the material after the acceptance(check), earlier bottom water-stopping system 4 was buried underground before concreting, before the concreting of band adjacent panels, bury underground the middle part elastomeric material, treat that upstream face plate portion elevation is all finished after, carry out the construction of top water-stopping system 3.
The 4th step, continue above-mentioned steps, finish until upstream concrete slab 1.
Embodiment of the present utility model is not limited to above-described embodiment, all belongs within the protection domain of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
