Description
Technical field
The utility model relates to a kind of buried thrust wall bushing waterproof seal.
Background technique
Hydro-structure and waterproof is had to the structure (as pond, water tower, pump house etc.) of strict demand in industrial building field, such building requires very high to the water-proof performance of structure self.But often engineering also do not complete or Practical Completion soon, adopt the wall-passing pipe place of traditional blocking technology just to occur seepage, post-processed not only time-consuming, effort, treatment effect is also poor.Along with the change of external force, seepage and constantly repairing become normality circulation and persistent ailment.This technology is conducive to the leakage problems thoroughly solving buried pipeline and heavy caliber thrust pipeline wall feed-through pipeline place.
Pass through circulating pump room body of wall place at the buried circulating pipe of existing engineering, because circulating pipe caliber is very large, high with the concentricity requirement of service sleeve during installation, construction is extremely inconvenient.Technician is by analyzing common wall feed-through pipeline waterproof blocking technology and study, find that common wall feed-through pipeline waterproof blocking technology mainly exists following problem: (1) to sleeve pipe and pipeline fabrication and installation required precision high, by pipeline gap, thickness of wall body, packing material, fill time compaction rate etc. affect, and after pipeline comes into operation, generation vibration, thrust and sedimentation have an impact to packed layer, easily produce seepage; (2) circulating pipe basis adopts flexible foundation, and place through walls is rigid foundation, the pipeline lever amplification stress of the asynchronous generation of sedimentation, produces uneven extruding to sealing material, causes waterproof failure, and percolating water exacerbates the liquefaction of the opaque soil body; (3) pressure piping is under different operating mode effects, because STRESS VARIATION has an impact to waterproofing effect, produces hidden danger to engineering later stage its usage economy and quality.
Summary of the invention
The utility model passes through circulating pump room body of wall place for current buried circulating pipe, because circulating pipe caliber is very large, during installation and the concentricity requirement of service sleeve high, construction is inconvenience extremely, easily cause the problem of leakage, the shortcoming that the fabrication and installation precision proposing a kind of large pipeline and sleeve pipe not easily ensures, makes, transports, installs the buried thrust wall bushing waterproof seal of economy, water-impervious.
Buried thrust wall bushing waterproof seal described in the utility model, comprise mine dam, steel pipe, sleeve pipe, the body of wall of described mine dam is arranged the mounting hole for inserting steel pipe, described casing pipe sleeve is in the outside of described mounting hole; In the steel pipe described in mine dam back side and the gap between described sleeve pipe, polysulfide sealing compound layer, swelling water mud layer and pitch spunyarn layer is filled successively from mine dam upstream face, it is characterized in that: the affixed sealing stiffening ring of steel pipe outer wall being positioned at described mine dam back side side, and the other end of affixed, the described steel expansion joint in one end of described sealing stiffening ring and steel expansion joint is affixed with the sleeve side walls being positioned at mine dam back side side.
Be connected by welding manner between described sealing stiffening ring and described steel expansion joint.
Be connected by welding manner between described steel expansion joint and described sleeve pipe.
Be connected by welding manner between described sealing stiffening ring and described steel pipe.
Middle part back-up ring is furnished with between described pitch spunyarn layer and described steel pipe.
Device described in the utility model can also pass through the connection between the sleeve pipe of body of wall between two next-door neighbour pond bodies.
Feature of the present utility model: adopt this technology, due to low to the space required precision between pipeline outer wall and sleeve pipe, the shortcoming that the fabrication and installation precision overcoming large pipeline and sleeve pipe not easily ensures, makes, transports, installs economy; Owing to have employed the waterproof technique that common waterproof combines with steel expansion joint, waterproof is reliable; Adaptable because hard and soft basis changes the sedimentation caused to pipeline through-wall place; The different operating mode of STRESS VARIATION when being in to(for) pipeline is adaptable.
The beneficial effects of the utility model are: 1) form airtight watertightness barrier by increasing steel expansion joint, waterproof reliability is effectively guaranteed; 2) by steel expansion joint, can the STRESS VARIATION value that cause such as extraction duct vibration, horizontal thrust, uneven settlement, temperature, operating maintenance operating mode, under the structural condition flexibly connected, realize the requirement of rigid waterproofing by welding, solve leakage problem when pipeline is in different operating mode; 3) by steel expansion joint and welding between sealing stiffening ring, sleeve pipe, pipeline, realize rigid waterproofing body, the reliability dependence of upstream face flexible blockage reduces, and effectively can reduce the installation precision requirement of steel expansion joint, construction of being more convenient for.
