Description
Technical field
The present invention relates to Hydraulic and Hydro-Power Engineering field, specifically a kind of exhaust valve pit.
Background technology
Traditional structure exhaust valve pit passes through the Pipeline Crossing Program well room side wall shape of side wall using main conduit's overcoat wall bushing
Formula.Between sleeve pipe and main pipeline antiseepage is carried out by the way of cushion rubber and filling spunyarn.Because the buried depth of main pipeline is larger, once
Wall bushing partial failure and the rich groundwater of place construction area, the outer Groundwater infiltration well room of well can be caused to cause in well
Ponding.There was dampness in the air, and environment can then aggravate the corrosion of steel pipe, electromechanical equipment, reduction of service life；And the excavation of conventional well room
Depth requirements are too high, and the dispensing demand such as the concrete of single valve pit, reinforcing bar is big, and infusion of financial resources is big.
The exhaust valve pit of traditional structure is using pipeline with being vented valve pit well room using being rigidly connected, and pipeline is with arranging
There is some difference for air valve chamber geological conditions, causes the settling amount of upstream and downstream pipeline outside well room and well room can be different, if
Pipeline integral rigidity is more than well room side wall concrete tensile strength, and side wall concrete can be caused to produce crack；If pipeline is overall
Rigidity is less than well room side wall concrete tensile strength, then the sedimentation of well yard piping is different from well indoor exhaust threeway, if in well
Outer Tube settling amount difference is excessive, can cause due to causing bell and spigot to destroy by means of gyration more than pipeline socket is maximum allowable
Seepage, or cause steel pipe to produce plastic deformation, so as to reduce pipeline useful life longevity.
The content of the invention
It is an object of the invention to provide one kind to be vented valve pit, avoid due to the differential settlement between pipeline and well room and
Pipeline or well cell structure are damaged.The barrier performance of well room is higher.It is steady to avoid side slope safety caused by fluting over long distances
Fixed and basis disturbance adverse effect.Possesses greater flexibility in mobilization.Cost is low.
In order to reach above-mentioned purpose, present invention employs following technical scheme, one kind exhaust valve pit, including main shaft room, institute
Stating itself bottom plate of main shaft room includes annular plate and central bottom plate, and it is permanent heavy to be formed between the central bottom plate and annular plate
Drop seam, the central bottom plate open up centre bore with annular plate by rubber water-proof band connection, the central bottom plate, the centre bore
The upper branch mouth of blow-off tee is installed, blow-off tee is 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 curved 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 except upper branch mouth, also with one
Zuo Zhukou and right main mouth, Zuo Zhukou and You Zhukou are all connected with main pipeline.
The present invention compared with prior art, has the advantages that：
1）Structure stress：
Box foundation structure exhaust valve pit blow-off tee is coupled with well room for one rigidity integrally, while blow-off tee also with its
Upstream and downstream main pipeline is connected using bell and spigot or Type of Welding.Because pipeline and exhaust valve pit are relatively independent, it uniquely connects
Socket part position is blow-off tee top manifold, and the position back-plane design is independent square underplate concrete, with surrounding floor concrete
Between be provided with permanent subsiding crack, the rubber fastening band used has larger permission deflection, avoided due to pipeline for flexible material
Differential settlement between well room and pipeline or well cell structure are damaged；
2）The antiseepage of well room：
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, generally higher than phreatic line, and well room is using rubber fastening band and well chamber outer wall cladding asphalt waterproofing volume
The dual seepage control measure of material, make the barrier performance of well room higher；
3）Work progress is stable on excavation slope and foundation bearing capacity influences：
Independent column foundation, main shaft cell structure and the main pipeline that the present invention is vented valve pit are substantially independent, Pipe installing and the construction of well room
Progress can be completely independent, is influenceed without cross-operation.This kind of structural gap valve pit construction is avoided caused by fluting over long distances
The adverse effect of the stable and basic disturbance of side slope safety；
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, makees in the absence of intersecting
Industry is constructed, and can be selected Pipe installing is synchronous with the construction of well room to carry out or by installing pipe according to live practice of construction situation
Road backfills in advance, carries out well room construction after arranging foundation ditch secondary excavation according to construction, possesses in mobilization bigger
Flexibility；
5）Investment analysis：
Relatively conventional exhaust valve pit, novel exhaust valve pit well room are shallow compared with conventional air valve pit.The concrete of single valve pit and match somebody with somebody
Muscle amount is few compared with traditional valve pit, is contrasted by calculating, and engineering uses new valve pit, and compared to traditional valve pit is used, quantities is reduced
50%.
