Abstract
The invention discloses a composite hydraulic high-pressure tunnel plug.A reinforced concrete front plug (3) and a reinforced concrete rear plug (4) are arranged in a construction branch tunnel (6), an engraved groove is arranged on the inner wall of the construction branch tunnel (6) between the reinforced concrete front plug (3) and the reinforced concrete rear plug (4), and an expansive clay plug (2) filled into the engraved groove is arranged between the reinforced concrete front plug (3) and the reinforced concrete rear plug (4). The notch groove is a triangular notch groove (1). The invention relates to an anti-seepage plugging technical scheme combining rigid and flexible materials, in particular to a composite hydraulic high-pressure tunnel plug which is low in permeability, good in sealing quality, simple in structure and convenient to operate.
Description
Technical field
The present invention relates to a kind of tunnel plug, particularly relate to a kind of composite hydraulic high-duty pressure tunnel plug for fields such as Hydraulic and Hydro-Power Engineering, water supply projects.
Background technology
Under prior art condition, after the construction of water conservancy project High Pressure Tunnel By Means, near the construction near certain limit diversion tunnel or between High Pressure Tunnel By Means, prop up hole and all adopt Reinforced Concrete Materials to carry out shutoff.The weak point of this technology is: (1) occurs the wall rock loosening ring of certain limit because construction blasting causes a construction hole country rock, cause the country rock permeability within the scope of relaxation zone to increase, (2) construction top, a hole blocking concrete is due to difficulty and the drying shrinkage phenomenon of vibrating, cause the top seal quality of steel concrete plug to be difficult for guaranteeing, occur infiltration in a large number.
Summary of the invention
The technical problem to be solved in the present invention is to provide the composite hydraulic high-duty pressure tunnel plug that a kind of permeability is low, airtight quality is good.
In order to solve the problems of the technologies described above, composite hydraulic high-duty pressure tunnel plug provided by the invention, plug 4 after plug and steel concrete be provided with steel concrete in a construction hole before, before described steel concrete, after plug and steel concrete, the construction between plug is propped up on the inwall in hole and is provided with cutting, is provided with the expansive clay plug being filled in described cutting before described steel concrete after plug and steel concrete between plug.
Described cutting is triangle cutting.
Adopt the composite hydraulic high-duty pressure tunnel plug of technique scheme, utilize plug two ends to bear the water pressure that High Pressure Tunnel By Means produces plug for steel concrete plug; By the expansive clay plug between plug after plug before steel concrete and steel concrete, reach the effect that antiseepage is processed, the characteristic of particularly having utilized swell deformation of expansive soil encountered with water, permeability significantly to reduce; Triangle cutting simultaneously makes scored position in compressive stress collected state, make the crack of this position country rock closed under the effect of compressive stress, permeability reduces, and the Permeability of rock that the wall rock loosening of avoiding rock mass to cause because of excavation explosion causes increases, and then the water leakage causing increases.This blocking technology is reasonable in design, simple in structure, easy to operate.
In sum, the present invention utilizes the cutting of country rock triangle to reduce the permeability of country rock, by implementing flexible expansion clay plug, reach antiseepage Expected Results, the stressed of plug born by plug after plug and steel concrete before the steel concrete at two ends, this technology is further perfect High Pressure Tunnel By Means antiseepage blocking technology, being the antiseepage blocking technology scheme that a kind of rigidity and flexible material combine, is that a kind of permeability is low, airtight quality good and simple in structure, easy to operate composite hydraulic high-duty pressure tunnel plug.
Accompanying drawing explanation
Fig. 1 is construction plug vertical section, a hole schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Referring to Fig. 1, High Pressure Tunnel By Means 5 is provided with a construction hole 6, plug 4 after plug 3 and steel concrete be provided with steel concrete in a construction hole 6 before, before steel concrete, after plug 3 and steel concrete, the construction between plug 4 is propped up on the inwall in hole 6 and is provided with triangle cutting 1, before steel concrete, after plug 3 and steel concrete, between plug 4, be provided with the expansive clay plug 2 being filled in triangle cutting 1, expansive soil fills strict control water content size in process in construction, and hits crucial point reason.
Referring to Fig. 1, adopt the composite hydraulic high-duty pressure tunnel plug of technique scheme, utilize plug two ends to bear the water pressure that High Pressure Tunnel By Means produces plug for steel concrete plug; By the expansive clay plug 2 between plug 4 after plug before steel concrete 3 and steel concrete, reach the effect that antiseepage is processed, the characteristic of particularly having utilized swell deformation of expansive soil encountered with water, permeability significantly to reduce; Triangle cutting 1 simultaneously makes scored position in compressive stress collected state, make the crack of this position country rock closed under the effect of compressive stress, permeability reduces, and the Permeability of rock that the wall rock loosening of avoiding rock mass to cause because of excavation explosion causes increases, and then the water leakage causing increases.This blocking technology is reasonable in design, simple in structure, easy to operate.
Claims (2)
1. a composite hydraulic high-duty pressure tunnel plug, it is characterized in that: in construction hole (6), be provided with before steel concrete plug (4) after plug (3) and steel concrete, described construction after plug before described steel concrete (3) and described steel concrete between plug (4) is propped up on the inwall of hole (6) and is provided with cutting, after plug before described steel concrete (3) and described steel concrete, between plug (4), is provided with the expansive clay plug (2) being filled in described cutting.
2. composite hydraulic high-duty pressure tunnel plug according to claim 1, is characterized in that: described cutting is triangle cutting (1).
