Background technique
The at present existing corresponding NBS of concrete reinforced pipe, standard No. is GB/T 11836-2009 and JC640/T-2010.It generally comprises concrete tube wall, the left end of concrete tube wall is fixedly connected with socket hoop, and the left side of concrete tube wall is positioned at the middle part of socket hoop, and the bellmouth anchor bar embeds in the concrete tube wall, the right-hand member of concrete tube wall is provided with the socket ring, and the outer wall of socket ring is embedded with O-ring seal.Some concrete reinforced pipe is welded with some bellmouth anchor bars for reinforcing fixing between socket hoop and the concrete tube wall at the right-hand member of socket hoop.At present, when the provided underground heat distribution pipeline, need to put concrete reinforced pipe in the periphery of heat distribution pipeline, but owing to will be applied to heat distribution pipeline, need concrete reinforced pipe to have preferably sealing and water proofing property, gentle with the water in the sealing concrete reinforced pipe, and prevent that groundwater seepage from entering to manage interior and the corrosion heat distribution pipeline.In addition, in some occasions, need to construct with jacking construction method, this requires concrete reinforced pipe to have higher structural strength, reduces construction quality in order to avoid cause end local damage or socket hoop and concrete tube wall to break away from the jacking construction process.And existing concrete reinforced pipe is in the jacking construction requirement that all can not adapt to heat distribution pipeline aspect sealing, waterproof and the structural strength top power.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of better tightness, water-impervious, heating power jacking construction reinforced concrete sleeve that structural strength is higher.
Heating power jacking construction reinforced concrete sleeve of the present invention, comprise concrete tube wall, the left end of concrete tube wall is fixedly connected with socket hoop, the left side of concrete tube wall is positioned at the middle part of described socket hoop, the right-hand member of socket hoop is welded with some bellmouth anchor bars, the bellmouth anchor bar embeds in the described concrete tube wall, the right-hand member of concrete tube wall is provided with the socket ring, the outer wall of socket ring is embedded with O-ring seal, be welded with the sealing steel loop coaxial with socket hoop on the inwall of wherein said socket hoop on the right side of concrete tube wall left side, be welded with on the right side of described sealing steel loop on the inwall of socket hoop with socket hoop coaxial stop reinforced steel bar ring, described sealing steel loop and stop and be provided with the water-swellable adhesive tape between the reinforced steel bar ring; The left side of described concrete tube wall is pasted with siliceous rubber cushion and siliceous two-way water stop O-ring seal, and described siliceous two-way water stop O-ring seal is between the inwall of the annular inner wall of described siliceous rubber cushion and described concrete tube wall.
Heating power jacking construction reinforced concrete sleeve of the present invention is provided with the injected hole that is communicated with socket ring inside and outside wall in the left side of described O-ring seal on the wherein said socket ring.
Heating power jacking construction reinforced concrete sleeve of the present invention, the left side of wherein said concrete tube wall is provided with circular groove at the engagement edge place with described socket hoop inwall, is filled with the waterproof sealing filler in the circular groove.
Heating power jacking construction reinforced concrete sleeve of the present invention is embedded with at least one prefabricated steel ring coaxial with concrete tube wall on the inwall of wherein said concrete tube wall.
Heating power jacking construction reinforced concrete sleeve of the present invention, the material of wherein said socket hoop are No. 16 manganese steel.
Heating power jacking construction reinforced concrete sleeve of the present invention, the inner and outer surface of wherein said socket hoop is coated with and is brushed with epoxy zinc rich primer.
Heating power jacking construction reinforced concrete sleeve of the present invention, the length of wherein said socket hoop is 285mm.
Heating power jacking construction of the present invention is that with the reinforced concrete sleeve difference from prior art heating power jacking construction of the present invention is with being welded with the sealing steel loop on the right side of concrete tube wall left side on the inwall of the socket hoop of reinforced concrete sleeve, the sealing steel loop can not only play the effect that stops its left and right sides groundwater seepage like this, and can reinforce fixing between socket hoop and the concrete tube wall when jacking construction, so that concrete tube wall is difficult for coming off with socket hoop and causes the gap during jacking construction.Be welded with on the right side of sealing steel loop on the inwall of socket hoop and stop reinforced steel bar ring, sealing steel loop and stop and be provided with the water-swellable adhesive tape between the reinforced steel bar ring, in case the water-swellable adhesive tape runs into water, will expand, thereby fill up and extruded concrete tube wall and socket hoop and sealing steel loop between the gap, play the sealing resistance effect.Gap when connecting in order further to seal two pipes between end face, the left side of concrete tube wall is pasted with siliceous rubber cushion and siliceous two-way water stop O-ring seal, siliceous two-way water stop O-ring seal is between the inwall of the annular inner wall of siliceous rubber cushion and concrete tube wall, siliceous like this two-way water stop O-ring seal can play in the internal wall of pipe orifice joint one deck seal action, siliceous rubber cushion can play buffer function in mouth of pipe end when jacking construction, prevent that the mouth of pipe is damaged.Heating power jacking construction of the present invention adopts with reinforced concrete sleeve and has more the water-tight design, and compared to existing technology, better tightness is so can be applicable to heat distribution pipeline.
Heating power jacking construction of the present invention is be provided with the injected hole that is communicated with socket ring inside and outside wall slip casting outside managing in manage can be at jacking construction the time on the socket ring in the reinforced concrete sleeve in the left side of O-ring seal, resistance when slip casting can be filled up the gap between pipe outer wall and the soil and also can reduce jacking, behind the injection forming with the self-closed injected hole.The left side of concrete tube wall is provided with circular groove at the engagement edge place with the socket hoop inwall, and when being filled with the waterproof sealing filler in the circular groove, the waterproof sealing filler can be filled up the gap that produces because jacking is stressed between socket hoop and the concrete tube wall.When being embedded with at least one with the coaxial prefabricated steel ring of concrete tube wall on the inwall of concrete tube wall, the prefabricated steel ring can be used as the welding matrix that sets up heat distribution pipeline, heat distribution pipeline the setting up in concrete tube wall of being more convenient for.It is because the large and corrosion-resistant grade of this material hardness is high that the material of socket hoop is elected No. 16 manganese steel as.The inner and outer surface of socket hoop is coated with and is brushed with epoxy zinc rich primer and can prevents further that socket hoop is corroded.When the length of socket hoop was elected 285mm as, it was longer to compare existing socket hoop length, can effectively reduce the Influence of Displacement that heat distribution pipeline temperature varying stress produces.
Below in conjunction with accompanying drawing heating power jacking construction of the present invention is described further with reinforced concrete sleeve.
