Abstract
The utility model discloses a buried high-pressure water channel or tunnel seepage-proofing lining structure, wherein a seepage-proofing steel tube (1) is arranged in a high-pressure pipeline section or a high-pressure branch pipeline section; leveling or backfill concrete (3) is arranged between an outer wall of the seepage-proofing steel tube (1) and the high-pressure pipeline section or the high-pressure branch pipeline section; and reinforced concrete liner (2) is arranged on an inner wall of the seepage-proofing steel tube (1). The excellent seepage-proofing performance of the steel tube is utilized to solve the seepage problem of the high-pressure water pipeline, and the excellent compressive property of the reinforced concrete is utilized to prevent the steel tube from bending and being damaged. The lining structure provides another technical support for further promoting development of the high water head pumped storage power station construction technology.
Description
Technical field
The utility model relates to a kind of liner structure; Particularly relate to a kind of antiseepage and supporting and protection structure that is used for Hydraulic and Hydro-Power Engineering, the embedded high pressure water channel in traffic engineering field or traffic tunnel, especially be directed against the antiseepage and the supporting of pumped storage power plant high pressure diversion tunnel pressure piping section and high pressure bifurcated pipe section.
Background technology
Under the prior art condition, the power station of underground power house and the high pressure water channel liner structure of pumped storage power plant are set adopt form of structure such as steel lining, reinforced concrete lining layer or concrete lining.Under high water head and the high external water pressure condition, steel lining form of structure advantage is that barrier performance is good, and convenient maintenance and replacement, its shortcoming are that buckling failure takes place easily in the steel pipe lining cutting under high external water pressure effect; Be control steel pipe lining cutting generation buckling failure; Need to adopt high-strength steel and select for use the big steel plate of thickness to carry out the making of steel pipe lining cutting; Its consequence is that the manufacture craft difficulty is big, drainage system need be set outside the steel pipe lining cutting simultaneously reduce external water pressure, thereby involve great expense.The advantage of reinforced concrete lining layer and concrete lining structure is not have buckling problem, and construction technology is simple, and is cheap.The shortcoming of reinforced concrete lining layer and concrete lining structure is under high hydraulic action, can form the crack; Barrier performance is relatively poor; The water under high pressure disasters such as causing a large amount of permeable or infiltration unstabilitys easily of exosmosing, even if adopting under the infiltrative situation of grouting treatment country rock, its antiseepage durability is not good yet.
The utility model content
The utility model technical problem to be solved is the weak point that exists to existing high pressure water conservancy project water channel liner structure form, and a kind of high pressure barrier properties, durability and structural stability good embedded high pressure water channel or tunnel sealing liner structure taken into account is provided.
In order to solve the problems of the technologies described above; Embedded high pressure water channel or tunnel sealing liner structure that the utility model provides; In pressure piping section or high pressure bifurcated pipe section, be provided with the antiseepage steel pipe; Between the outer wall of described antiseepage steel pipe and described pressure piping section or high pressure bifurcated pipe section, be provided with levelling or fill concrete, be provided with reinforced concrete lining layer at the inwall of described antiseepage steel pipe.
Adopt the embedded high pressure water channel or the tunnel sealing liner structure of technique scheme; Through being set, certain thickness reinforced concrete lining layer shares the internal water pressure that acts on the outer field antiseepage steel pipe of steel concrete in the antiseepage steel pipe; To reduce the thickness of antiseepage steel pipe; Utilize the good compressive property of steel concrete simultaneously; Opposing is thoroughly avoided the generation of the buckling failure phenomenon of antiseepage steel pipe through the external water pressure that the outside steel pipe transmission comes, and cancellation simultaneously only is provided with the drainage system in the high pressure water channel under the steel lining situation.Through satisfying stressed in the reinforced concrete lining layer arranged outside and certain thickness antiseepage steel pipe durability, realize the compound lining structure block antiseepage function after the crack appears in reinforced concrete lining layer.Unite opposing external water pressure and internal water pressure owing to adopt reinforced concrete lining layer and antiseepage steel pipe; The performance and the thickness requirement of the steel pipe steel of pressure piping section or high pressure bifurcated pipe section have been reduced; Can adopt the steel plate of domestic production to carry out processing and fabricating; Avoided the high-strength steel plate that thickens of use import, can reduce construction costs significantly, promotion prospect is wide.This form of structure is reasonable in design, and is simple in structure, easy to operate.
The advantage of the utility model is: utilize the good barrier performance of steel pipe to solve the leakage problems of high pressure water channel, and utilize the steel concrete good pressure resistance can prevent steel pipe generation buckling failure.This liner structure form provides another technical support for the progress that further promotes the High Head Pumped Storage Power Station construction technique.
Description of drawings
Fig. 1 is the section of structure of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, in pressure piping section or high pressure bifurcated pipe section 4, be provided with antiseepage steel pipe 1, between the outer wall of antiseepage steel pipe 1 and pressure piping section or high pressure bifurcated pipe section 4, be provided with levelling or fill concrete 3, be provided with reinforced concrete lining layer 2 at the inwall of antiseepage steel pipe 1.
Referring to Fig. 1; Through being set, certain thickness reinforced concrete lining layer 2 shares the internal water pressure that acts on the outer field antiseepage steel pipe 1 of steel concrete in antiseepage steel pipe 1; To reduce the thickness of antiseepage steel pipe 1, utilize the good compressive property of reinforced concrete lining layer 2 simultaneously, the external water pressure that opposing comes through the outside steel pipe transmission; Thoroughly avoid the generation of the buckling failure phenomenon of antiseepage steel pipe 1, cancellation simultaneously only is provided with the drainage system in the high pressure water channel under the steel lining situation.Through satisfying stressed in reinforced concrete lining layer 2 arranged outside and certain thickness antiseepage steel pipe 1 durability, realize the compound lining structure block antiseepage function after the crack appears in reinforced concrete lining layer 2.Unite opposing external water pressure and internal water pressure owing to adopt reinforced concrete lining layer 2 and antiseepage steel pipe 1; The performance and the thickness requirement of the steel pipe steel of pressure piping section or high pressure bifurcated pipe section 4 have been reduced; Can adopt the steel plate of domestic production to carry out processing and fabricating; Avoided the high-strength steel plate that thickens of use import, can reduce construction costs significantly, promotion prospect is wide.This form of structure is reasonable in design, and is simple in structure, easy to operate.
