Description
Technical field
Technical field more particularly to one kind the present invention relates to the pipe gallery for Urban Buried Pipeline Network Systems are divided up and down
The prefabricated piping lane of body formula.
Background technology
Pipe gallery refers to that a municipal administration is built below urban road shares tunnel, by electric power, communication, water supply, combustion gas
One is concentrated on etc. a variety of municipal pipelines, " unified planning, unified construction, unified management " is carried out, to accomplish the comprehensive of the underground space
It closes using shared with resource.
Traditional pipe gallery construction generally uses cast in situs, it is necessary to carry out steel bar meter binding, branch at the construction field (site)
The processes such as mould, concrete cast, maintenance, form removal, not only working procedure is complicated for the method, long construction period, while also presence needs
The problems such as larger raw material is wanted to store and process factory site.
In order to solve the constructional deficiency of cast in situs formula piping lane, there is integrated precast piping lane, but integrated precast
Often volume and weight is larger for piping lane, and the transport and on-site hoisting from factory to construction site are extremely inconvenient, so as to occur
Fabricated construction piping lane.
And existing fabricated construction piping lane is also to belong to integrated precast piping lane scope in fact, simply opposite monoblock type is pre-
Tubulation corridor length reduction；Its casting craft generally uses vertical one-piece casting or horizontal one-piece casting；
Horizontal one-piece casting, often all there are several technological deficiencies：
1) since the height of prefabricated piping lane is high, weight is big, show so as to often swollen mould occur in the lower part of mold when pouring
As so as to cause burn failure；
2) since mold is monoblock type, so as to cause from top to bottom into mold during concrete perfusion, in mold bottom
Air and bubble can not be completely exhausted out, there is cellular defect so as to cause molding piping lane bottom plate or even local dew occur
Muscle phenomenon seriously affects structural strength, service life and leakproofness；
3) poured, the demoulding is difficult, and grinding tool easy to wear, reduces die life.
And vertical one-piece casting, there are technological deficiencies：
1) mating surface poured when top surface is piping lane assembling of mold, using vertical one-piece casting, mold can not ensure
The flatness in the face poured, so as to which the piping lane after influencing is assembled and sealed.
At present, also occur the prefabricated piping lane of two-piece unit formula, such as Patent No. in the industry of prefabricated piping lane
The 201621083138.3 prefabricated assembled more cabin pipe galleries of one kind, the reinforcement member connection mode of disclosed pipe gallery
Using the pre-buried rod iron of lower member, upper member penetrates rod iron and is connected by rebar sleeve, but it was verified that in prefabricated lower structure
, it is necessary to which fixed pre-buried rod iron, comparatively laborious during part；In addition after the completion of upper member and lower member assembling, steel is penetrated to upper member
In the upper preformed hole of stick during slip casting, it may appear that bubbling phenomenon causes slip casting insufficient, and rod iron does not fasten.
The content of the invention
For above-mentioned technological difficulties, it is an object of the present invention to provide a kind of prefabricated piping lane of two-piece unit formula, prefabricated sides
Just, it is and easy for installation, it is solid.
Its technical solution is as follows：
A kind of prefabricated piping lane of two-piece unit formula, including upper piping lane and lower piping lane；The upper piping lane includes top plate and two upsides
Plate；Lower piping lane includes bottom plate and two lower side panels；Two epipleurals and two lower side panels are connected, and inside is hole capital after selling all securities；
The lower side panel of the epipleural of upper piping lane and lower piping lane sets multigroup through hole, and is set above the through hole of epipleural on top plate
Pre-buried slot, the through hole lower section lower side panel inner wall of lower side panel set pre-buried slot；PC rod irons are through the logical of epipleural and lower side panel
Hole, and both ends respectively upper pre-buried slot and under pre-buried slot connected by anchor slab and bolt-nut, it is easy for installation, and under
The up slip casting of the through hole of side plate should not generate bubble in through hole.
Shearing boss is set in the mating surface of the lower side panel, shearing groove is set in the mating surface of epipleural, and is worked in coordination；
On the one hand cooperation is facilitated to align, on the other hand increases the shearing between piping lane up and down, prevents piping lane dislocation up and down；The PC rod irons
Through shearing boss and shearing groove, the intensity of enhancing shearing concave and convex platform；
Anchor slab in the upper pre-buried slot is upper anchor slab, under anchor slab in pre-buried slot be lower anchor slab, the upper anchor slab
It is compound seal anchor slab with lower anchor slab；
Upper anchor slab includes the upper platen that centre sets the perforation of PC rod irons, and the upper periphery of upper platen sets " mouth " grommet type seal,
Centre sets the gas vent connected with the perforation of PC rod irons；
Lower anchor slab includes the lower fastening plates that centre sets the perforation of PC rod irons, and the upper periphery of lower fastening plates sets " mouth " grommet type seal,
Centre sets the injected hole connected with the perforation of PC rod irons.
It is fastened when upper and lower piping lane is connected by PC rod irons, anchor slab and anchorage nut, under under the pre-buried downward anchor slab of slot
The injected hole concrete perfusion of fastening plates is starched, and the air in through hole is discharged from the gas vent of upper platen；Along through hole from lower past
Upper slip casting, slip casting is complete, and the concrete grout being perfused in through hole can be avoided bubble phenomenon occur, so as to influence PC rod irons to upper and lower
The bonding strength of piping lane；Meanwhile into through hole during slip casting, shearing concave and convex platform can be filled along PC rod irons, so as to increase up and down
The bonding strength and shear strength of side plate.
One fabricated construction piping lane is split as two-piece unit formula structure, on the one hand can mitigate single-piece pours weight
Amount, is readily transported, on the other hand, split type upper piping lane and lower piping lane can be used it is horizontal pour, pouring quality is good, respectively matches somebody with somebody
The fit precision in conjunction face is high, is installed convenient for assembling；Piping lane is connected by a PC rod iron up and down simultaneously, and bonding strength is good, is led to
It crosses to through hole slip casting from the bottom up, slip casting effect is good, and structural strength is good.
