Description
Technical field
The utility model relates to a kind of high-velocity flow hydraulic structure deformation joint structure.
Background technology
In hydraulic structure, for avoiding since the effect of variations in temperature, uneven settlement of foundation or earthquake factor building structure is deformed or destroys, usually the deformation joint that adopts width to be about 2cm is divided into several separate units with building structure, make hydro-structure have the various deformation ability of stronger adaptation, this seam is called deformation joint.The traditional structural design of deformation joint as shown in Figure 2.Caulking material is three oily two felts in the deformation joint, and establishes the rubber sealing or the copper sheet sealing prevents that current from infiltrating ground by deformation joint.Practice shows that in high-velocity flow (water flow velocity is greater than 20m/s) hydraulic structure, under the effect of high-velocity flow pressure fluctuation meter, traditional deformation joint structure has but become the weakest position of hydraulic structure, and therefore a plurality of engineerings cause great security incident.Integrate and mainly contain following reason: (1) caulking material is difficult to satisfy the requirement of high-velocity flow in the planeness of seam face, causes the formation of cavitation, is the inducement of deformation joint structural deterioration; (2) caulking material intensity is difficult to satisfy the requirement that high-velocity flow dashes the mill cavitation corrosion.Under the effect of cavitation corrosion and erosion, caulking material destroys, and the formation of aggravation cavitation and the effect of cavitation corrosion make deformation joint concrete on every side begin to destroy, and strengthen damage area gradually; (3) be difficult to vibration compacting during the concrete pouring of sealing bottom, sealing is unreliable.Current progressively penetrate into ground along sealing surface and weak part, form reverse osmotic pressure in the hydraulic structure bottom; (4) the seam end, do not have drainage.Can't drain owing to be penetrated into the water of ground, the osmotic pressure that acts on the hydraulic structure is continued to increase, the hydraulic structure structure is torn or started, cause the hydraulic structure structural deterioration.This shows, in the high-velocity flow hydraulic structure, adopt traditional deformation joint structure to exist bigger defective and potential safety hazard, in case the engineering accident, consequence is very serious, removes and not only causes bad social influence, also needs reconstruction, increases construction investment.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of high-velocity flow hydraulic structure deformation joint structure of safe and reliable, easy construction, thereby overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution of the utility model is proposed: a kind of high-velocity flow hydraulic structure deformation joint structure.Comprise deformation joint, copper sheet sealing, embedding in deformation joint has polyethylene closed pore plastic plate, being filled with epoxy mortar near in the deformation joint of flow surface, is filled with vulcanized rubber in the bottom of epoxy mortar.
In the above-mentioned high-velocity flow hydraulic structure deformation joint structure, on the copper sheet sealing, be stained with SR plastic sealing bar.
In the aforesaid high-velocity flow hydraulic structure deformation joint structure, be provided with the blind material of hollow draining in the bottom of deformation joint, geotextiles arranged in the coated outside of the blind material of hollow draining.
The beneficial effects of the utility model: compared with prior art, the utility model is embedded in polyethylene closed pore plastic plate at deformation joint, has simplified construction sequence; In the close deformation joint of flow surface, fill the epoxy mortar filleting, can guarantee the planeness and the caulking material intensity of water surface, the bottom filling high viscosity of epoxy mortar, high-intensity vulcanized rubber, when having improved this part caulking material intensity, also formed the first line of defence in the high-velocity flow infiltration deformation joint.Simultaneously, be stained with SR plastic sealing bar on the copper seal of the utility model in deformation joint, the defence line, second road that current are infiltrated in the deformation joint is more reliable.In addition, the utility model is provided with the blind material of hollow draining on the ground of the bottom of deformation joint, and in the coated outside geotextiles of the blind material of hollow draining, to drain infiltration, avoids causing the destruction of high-velocity flow to hydraulic structure because of infiltration forms reverse seepage pressure.The utility model not only can keep the needs of the variation of deformation joint adaptive temperature, uneven settlement of foundation or earthquake factor, but also can make deformation joint body structure surface planeness, caulking material intensity satisfy the requirement of high flowing water stream, the excretory function that has anti-preferably current infiltration and infiltration simultaneously, make the deformation joint structure can safe operation under the high-velocity flow panting action, have advantages such as safe and reliable, easy construction.
