Specific implementation mode
The preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
A kind of prefabricated pipe gallery joint connecting structure of the present embodiment is as shown in Figure 1, 2, in the tip side of pipe gallery 1
Face is equipped with annular groutnick 2, grout hole 3 and air discharge duct 4.The middle part in piping lane end face is arranged in groutnick 2, along piping lane end
Face is circular layout, and groove is in inverted trapezoidal, rectangle or arc, and maximum open width is 50mm-200mm, depth 60mm-210mm.
It is respectively equipped with interior sealing adhesive tape groove 6 and external seal adhesive tape groove 5 inside and outside groutnick 2, forms the sealing of two rings, sealing joint strip
The groove of slot is higher by inverted trapezoidal, rectangle or arc, opening width 20mm-40mm, depth 5mm-10mm, fluid sealant bar groove
Piping lane end face 10mm-20mm.Grout hole 3 is arranged in the inside of connector end bottom, aperture 30mm-60mm, and with grouting
Groove 2 communicates.Air discharge duct 4 is arranged the top in connector end face, symmetrical each one, and is communicated with groutnick 2.Piping lane end
Corner angle do chamfered inside and outside the surrounding of face, and the size of chamfering is 20mm*20mm.1 connector of pipe gallery is additionally provided with prestressing force
Stretch-draw anchor body 9 is arranged at the corner location in piping lane.Prestressed stretch-draw anchor body 9 is triangular in shape, in the centre of triangle
Be reserved with presstressed reinforcing steel 10 wears muscle hole.
Pipe gallery 1 can be Dan Cang, double storehouses or more storehouses, and section form is rectangle, round or ellipse.2-section pipe corridor
Docking a kind of embodiment be：First cleaning connector end face, in the interior sealing adhesive tape groove 6 and external seal adhesive tape groove 5 of both ends of the surface
Paste water-swellable adhesive tape.Then 2-section pipe corridor docking, the air discharge duct 4 of both ends of the surface is opposite two-by-two at this time, forms exhaust outlet,
The groutnick 2 of both ends of the surface forms a closed grouting ring cavity.By the tensioning on prestressed stretch-draw anchor body 9 of presstressed reinforcing steel 10
2-section pipe corridor is anchored, the intensity of piping lane connector can so be effectively ensured, reduces the joint distortion problem caused by extraneous factor.It connects
After head is fixed, on the inside of the connector below grout hole 3 in be pumped into microdilatancy water-proof concrete, observation upper air vent works as top
When two exhaust outlets have concrete to emerge, pump concrete is customized, extra coagulation around exhaust outlet is cleared up in plugging grouting hole 3
Soil is simultaneously closed flat plastering；While pumping grouting, using microdilatancy waterproof mortar or marine glue by the chamfering of surrounding inside and outside joint
Piece smoothes out, and completes the connector connection of 2-section pipe corridor.Inside and outside bevel edge smears seam, two seals adhesive tape groove and grouting ring cavity sealing,
5 waterproof sealings construction is formed altogether in the joint area of piping lane.The cavity that is in the milk is interior to fill microdilatancy water-proof concrete, anti-for connector
While water provides safeguard, the intensity of itself is also resistant against the internal force that connector is generated by deformation, ensures the intensity of connector.
2-section pipe corridor docking another embodiment be：First cleaning connector end face, in the interior sealing adhesive tape groove 6 of both ends of the surface
With paste water-swellable adhesive tape in external seal adhesive tape groove 5, and the inflatable rubber ring of annular is placed in groutnick 2, by rubber
The inflating port of circle is fixed in the grout hole 3 of connector bottom.Then 2-section pipe corridor is docked, and by presstressed reinforcing steel 10 in prestressing force
Stretch-draw anchor 2-section pipe corridor on stretch-draw anchor body 9.After connector is fixed, on the inside of the connector below grout hole 3 in be pumped into air (powder
Body waterproof material, microdilatancy water-proof concrete), whether observation exhaust ports are filled by rubber ring, while observing pumping pressure table,
Ensure that rubber ring intumescent filler is entirely in the milk cavity, then blocks inflating port, grout hole 3 is blocked with Interal fixation, uses cement bonded sand
Slurry smoothes out exhaust outlet；While pumping, using microdilatancy waterproof mortar or marine glue by the chamfering piece of surrounding inside and outside joint
Floating is tamped, the connector connection of 2-section pipe corridor is completed.After because of extraneous factor sliding deformation occurs for piping lane connector, grouting can be opened
Sealing steel plate at hole 3, into rubber ring secondary pumped air or powder waterproof material fill up generating in time because of joint distortion
Crack.
