Description
Technical field
The utility model is related to hydraulic and hydroelectric engineering field, specifically a kind of exhaust valve pit.
Background technology
1. traditional structure exhaust valve pit passes through the Pipeline Crossing Program well room side wall of side wall using main conduit's housing wall bushing
Form.Between casing and main pipeline antiseepage is carried out by the way of cushion rubber and filling spunyarn.Since the buried depth of main pipeline is larger, one
The partial failure of denier wall bushing and the rich groundwater of place construction area can cause the outer Groundwater infiltration well room of well to cause well
Internal water accumulation.There was dampness in the air, and environment can then aggravate the corrosion of steel pipe, electromechanical equipment, shorten the working life；And the digging of traditional well room
Pick depth requirements are excessively high, and the dispensings demand such as concrete, reinforcing bar of single valve pit is big, and infusion of financial resources is big.
2. the exhaust valve pit of traditional structure using pipeline with exhaust valve pit well room using rigid connection, pipeline with
Being vented valve pit geological conditions, there is some difference, well room and the settling amount of the outside upper downstream line of well room is caused to will be different, such as
Fruit pipeline overall stiffness is more than well room side wall concrete tensile strength, and side wall concrete can be caused to generate crack；If pipeline is whole
Body rigidity is less than well room side wall concrete tensile strength, then the sedimentation of well room Outer Tube is different from blow-off tee in well room, if well
Inside and outside pipeline settling amount difference is excessive, can cause bell and spigot to be caused to break by means of gyration due to being more than that pipeline socket is maximum allowable
Bad leakage causes steel pipe to generate plastic deformation, so as to reduce pipeline useful life longevity.
Invention content
The purpose of this utility model is to provide a kind of exhaust valve pits, avoid due to uneven heavy between pipeline and well room
It drops and pipeline or well room structure is damaged.The barrier performance higher of well room.Avoid the side slope peace that fluting generates over long distances
The full adverse effect stablized and basis disturbs.Has greater flexibility in mobilization.It is at low cost.
In order to achieve the above objectives, the utility model employs following technical solution, a kind of exhaust valve pit, including main shaft
Room, main shaft room itself bottom plate include annular plate and central bottom plate, are formed between the central bottom plate and annular plate
Permanent subsiding crack, for the central bottom plate with annular plate by rubber water-proof band connection, the central bottom plate opens up centre bore, should
Centre bore installs the upper branch mouth of blow-off tee, and blow-off tee is made to be connected with main shaft room.
The upper branch mouth outer circumferential walls connection stiffening ring of the blow-off tee, stiffening ring are inlaid into central bottom plate again.
Described rubber fastening band one end is sealed to be fixed in annular plate, and the other end is sealed to be fixed on central bottom plate
It is interior, and naked leakage part arc-shaped shape of the rubber fastening band in permanent subsiding crack.
Main shaft room bottom four corners are fixed on column foundation upper end, and the blow-off tee is in addition to upper branch mouth, also there are one tool
Zuo Zhukou and right main mouth, Zuo Zhukou and You Zhukou are all connected with main pipeline.
The utility model compared with prior art, has the advantages that：
1）Structure stress：
It is that a rigidity is whole, while blow-off tee that blow-off tee is coupled by box foundation structure exhaust valve pit with well room
It is connect with its upstream and downstream main pipeline using bell and spigot or welding form.Due to pipeline with exhaust valve pit be it is relatively independent, only
One connecting portion is blow-off tee top manifold, which is independent rectangular underplate concrete, is mixed with surrounding floor
Be equipped with permanent subsiding crack between solidifying soil, the rubber fastening band used is for flexible material, with larger permission deflection, avoid due to
Differential settlement between pipeline and well room and pipeline or well room structure are damaged；
2）Well room antiseepage：
The main shaft room of column foundation structure air bleeding valve is located at more than main pipeline crest level, and the thickness of earth-fill cover of well room bottom plate is generally
Less than 1.5m, under normal circumstances higher than phreatic line, and well room is prevented using rubber fastening band and well room outer wall cladding pitch
The dual seepage control measure of water coiled material makes the barrier performance higher of well room；
3）Work progress is stable on excavation slope and foundation bearing capacity influences：
The utility model exhaust independent column foundation of valve pit, main shaft cell structure and main pipeline are substantially independent, Pipe installing with
Well room construction can be completely independent progress, be influenced without cross-operation.This kind of structural gap valve pit construction is avoided and is opened over long distances
The side slope safety that slot generates stablizes and the adverse effect of basis disturbance；
4）Analysis of Time-limit：
The independent column foundation of column foundation structure exhaust valve pit is completely independent progress with main shaft room with Pipe installing, and there is no friendships
Job execution is pitched, and Pipe installing progress synchronous with well room construction can be selected according to live practice of construction situation or will have been pacified
Tubulature road backfills in advance, carries out well room construction after arranging foundation pit secondary excavation according to construction, has more in mobilization
Big flexibility；
5）Investment analysis：
Relatively traditional exhaust valve pit, novel exhaust valve pit well room are shallow compared with conventional air valve pit.The concrete of single valve pit
It is few compared with traditional valve pit with quantity of reinforcement, it is compared by calculating, engineering uses novel valve pit, compared to using traditional valve pit, quantities
Reduce 50%.
