Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail below in conjunction with preferred embodiment.
Referring to accompanying drawing, a kind of municipal wastewater abnormity concrete pipe, is cylindrical pipeline body 2 including profile, and described pipeline body inner chamber lateral cross section shape is in abnormity inner chamber.The lateral cross section shape of described pipeline body inner chamber is that semi-circular arc 1-1 by upper and lower two different-diameters, 1-2 smooth kiss by symmetrical circular arc 1-3 and connect and constitute pipeline body abnormity inner chamber 1.The top semi-circular arc radius of described pipeline body abnormity inner chamber is 400-800mm, and lower semicircular arc radius is 200-425mm.The present embodiment top semi-circular arc radius is 800mm, and lower semicircular arc radius is 400mm, duct length 3M.The specification of design pipeline body abnormity inner chamber: the lower semicircular arc radius of abnormity inner chamber with top semi-circular arc radius specification is: 200-400mm or, the abnormity lower semicircular arc radius of inner chamber and top semi-circular arc radius specification 250-500mm or 300-600mm or 350-700mm or 400-750mm and 750-1500mm.Abnormity concrete pipe is extruded through grinding tool vibrations by armored concrete.Pipeline body abnormity inner chamber both can guarantee that the flow velocity of sewage, avoid foreign material deposition blocking pipeline, such as the when of urban population 50,000 people, the caliber of bottom 400mm just can meet the discharge capacity of sewage, when urban population increases to 500,000 people, the discharge capacity of sewage increases, and the caliber of bottom 400mm can not meet needs, now the caliber of top 800mm simultaneously works as effect, still can ensure that the discharge capacity of sewage.Work as rainy season set at ordinary times, it is also possible to auxiliary cities and towns are used as draining, and one-time investment a century is enjoyed.
The lateral cross section shaped part semi-circular arc of described pipeline body abnormity inner chamber is symmetrically arranged on two with preformed hole 3, and described preformed hole, along longitudinally through pipeline body, runs through steel strand wires (not shown) in described preformed hole.A diameter of 120mm of two preformed holes of the present embodiment, both can play the deadweight alleviating pipeline body, can run through again the steel strand wires of Shi Hanzhang after pipe jacking construction completes.Steel strand tension completes grouting behind shaft or drift lining and fills.Shi Hanzhang steel strand wires not only increase the globality of this section of sewer line, increase the stability of pipeline, but also further ensure that the shock resistance of pipeline, prevent pipeline displacement, work progress need to the air-supply of equipment cooling, preformed hole plays again and send wind action, it is achieved that the function that a hole is multiplex.
In described pipeline body abnormity, cavity wall is provided with corrosion-inhibiting coating 4.Resident's sewage in cities and towns mostly contains acid and alkaline matter, because sewage has corrosion with acid and alkaline matter for ordinary cement pipe, inside is brushed with corrosion-inhibiting coating, prevent the corrosion to pipe of cement, improve service life, reduce the tubing resistance to sewage current simultaneously, accelerate the flow velocity of sewage current.
Described pipeline body both ends of the surface are smooth end face, and pipeline body both ends of the surface are respectively equipped with grafting tongue and groove 5 and accept tongue and groove 5-1, and described grafting tongue and groove is female grafting tongue and groove end less than pipeline body end face, and being grafting tongue and groove is inside recessed pipeline body end face；It is provided with the grafting taper seat of indent from pipeline body wall thickness central line to the mouth of pipe inside described grafting tongue and groove end；Described undertaking tongue and groove is that male type accepts tongue and groove end, is provided with the grafting taper seat of evagination outside described undertaking tongue and groove end from pipeline body wall thickness central line to the mouth of pipe.Described grafting taper seat is 12 °-15 ° with angle 5-3 of pipeline body wall thickness central line.Concrete pipe accepts the advantage with splicing interface；In pipe pushing technology, stress surface, at the mouth of pipe, is accepted and splicing interface uniform force, the tapering of junction design, it is ensured that pipeline is adjustable when installing, and will not injure the mouth of pipe.
Referring to Fig. 2, the preferred version of the present embodiment is, described undertaking tongue and groove is provided with the locating slot 6 of fixing seal rubber ring 8.Two, position of sealing ring design is hollow and three to groove; (separate case application) is functionally equivalent to four roads and seals; sealing ring width 60mm; thus the flexibility protecting the mouth of pipe combines the most impaired; the material of sealing ring uses silastic material; there is durable antiseptic property and preferably elastic, guaranteed the tight linking of interface by the crush seal circle of concrete interface.
Described grafting tongue and groove and undertaking tongue and groove are respectively equipped with trapezoidal groove 7 by paracentral medial surface.Trapezoidal groove it is designed with inside pipe, after the complete two pipe grafting of pipe jacking construction, trapezoidal groove shape assumes diamond in shape shape groove, diamond shaped groove filled polyurethane sealing compound, improve the sealing of sewage conduct further, diamond shaped groove structure ensures that polyurethane sealant does not falls out, and plays the effect that insides of pipes seals.
Use asbestos pad 9 as anti-crushing pad between the mouth of pipe of the municipal wastewater abnormity concrete pipe being mutually inserted, asbestos pad can play antihunt action, and the resilience of asbestos pad is less, can reach the requirement of design, retain certain design gap, the problem brought to pipeline of expanding with heat and contract with cold will not be produced.
Municipal wastewater abnormity concrete pipe processing technology uses self-compacting concrete processing technology, it is ensured that the secret room degree of concrete；Improving productivity ratio, owing to need not vibrate, the time of concreting significantly shortens, and labor strength is greatly lowered, and needs the minimizing of workman's number.Improving the environment of work, improve the quality of concrete surface, do not have tube surfaces bubble or voids and pits, it is not necessary to secondary carries out skin patching, tube surfaces is smooth, and degree of compaction is good, increases the mobility of sewage.The general 3M of pipe range, has gap 10mm after two pipe grafting.
The above-mentioned detailed description this kind of municipal wastewater abnormity concrete pipe carried out with reference to embodiment; it is illustrative rather than determinate; can according to restriction scope list several embodiments; therefore without departing from changing and modifications under this utility model general plotting, within protection domain of the present utility model should be belonged to.
