Prefabricated wedge shape flexible interface assembling piping lane
This practical reinforcing bar is novel belongs to concrete pipe gallery technical field, is specifically related to a kind of prefabricated wedge shape flexible interface assembling piping lane.
Pipe gallery is the common tunnel of City Buried Pipeline, also known as common trench, it is the large body passage of a kind of pre-plugged in underground, then will supply water, blowdown, air feed, heat supply, electric power, all kinds of underground utilities reasonable Arrangement such as communication is in piping lane, realize unified planning, Uniting, unified construction, unified management, the underground space is fully utilized, thus avoid road repeatedly to excavate to greatest extent, save and always drop into, avoid affecting urban ground traffic.And prefabricated assembled piping lane is in advance at produce in factory, adopts stream curing, the production cycle more than 50% can be shortened; Because factorial praluction, not climate condition, job site restriction, so work efficiency is high, energy-conserving and environment-protective, piping lane quality secure; Sizing punching block iterative cycles uses, and can reduce construction costs more than 20%.Piping lane inside is provided with the pipeline of various water, electric facility, and particularly the waterproof requirement of power telecommunication pipeline is high especially, and joint does not admit of any seepage.There has been proposed the technical scheme of many prefabricated assembled piping lanes for this reason.But existing prefabricated assembled piping lane, the work plane of its birdsmouth and interface is all straight, and on the work plane of interface, be shaped with 1-2 the seal groove installing sealing ring or 1-3 the boss claiming to install sealing ring, birdsmouth and interface work plane gap is therebetween very little, and the single body weight weight of piping lane is wanted more than 5 tons at least, large-scale piping lane weight wants more than 30 ton, in out-of-flatness groove, the birdsmouth of adjacent piping lane and the abutting joint of interface very difficult, also easily rubber seal is squeezed bad, thus had a strong impact on construction speed and the installation quality of piping lane laying.As publication number: the birdsmouth in the technical scheme such as CN202580450U " the impervious inspection structure in New Pre tubulation corridor ", publication number CN101586700A " precast concrete pipe gallery with longitudinal bars ", notification number: CN101586709A " precast concrete pipe gallery " and the structure of interface all exist above-mentioned disadvantage.
Summary of the invention
The purpose of this utility model to provide a kind of prefabricated wedge shape flexible interface assembling piping lane, it can overcome the deficiencies in the prior art, make the abutting joint of the birdsmouth of adjacent piping lane and interface easy, quick, thus construction speed and the installation quality of the laying of prefabricated piping lane can be increased substantially, effectively prevent interface percolating water.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of prefabricated wedge shape flexible interface assembling piping lane, by ectonexine longitudinal reinforcement and circumferential reinforcement, formed by the gallery in the square of template casting and compacting of concrete or the circular or oval corridor body of rectangle, corridor body, body two ends, corridor are birdsmouth and interface respectively, it is characterized in that: birdsmouth, interface are shaped with the connection inclined-plane of angle of inclination complementation, the connection inclined-plane of interface tilts from inside to outside, and the connection inclined-plane ecto-entad of birdsmouth tilts; The connection of adjacent piping lane, is equipped with wedge-shaped rubber sealing ring between interface, birdsmouth.
As preferably, the connection inclined-plane of described interface, birdsmouth, the angle of inclination of their complementations is 2.5 ° ~ 4.5 °, and wedge-shaped rubber sealing ring and above-mentioned angle of inclination match.
The beneficial effects of the utility model: because birdsmouth, interface are shaped with the connection inclined-plane of angle of inclination complementation, the installation inclined-plane of interface tilts from inside to outside, the installation inclined-plane ecto-entad of birdsmouth tilts, so the connection of adjacent piping lane, form two inverted triangular structures each other, when docking, interface, birdsmouth work plane gap are therebetween larger, therefore docking easily, quick, thus the construction speed of the laying of prefabricated piping lane can be increased substantially; Between adjacent piping lane interface, birdsmouth, wedge-shaped rubber sealing ring is housed, carries out jacking construction by oil jack jacking force during installation, push away tighter and tighter, make wedge-shaped rubber sealing ring be compressed into strip, can not rebound, good airproof performance, can accomplish watertight; In addition, with the sealing of wedge-shaped rubber sealing ring, there is flexibility, can make adjacent piping lane up and down, left and right can deflect 0.5 ~ 1.0 °, adapt to the groove sedimentation of engineering soft damage local, and earthquake intensity 7 grades can be resisted, there is good quakeproof and quake-resistant function.

Detailed description of the invention
Embodiment below just represented by Fig. 1-7 is made a step to the utility model and is described, it is by ectonexine longitudinal reinforcement 1 and circumferential reinforcement 2, the gallery 5 watered by template concrete 3 in the corridor body 4 of the corridor body 4 of the rectangle smash, rectangle is formed, corridor body 4 two ends of rectangle are birdsmouth 6 and interface 7 respectively, birdsmouth 6, interface 7 are shaped with the connection inclined-plane 8 of angle of inclination d complementation, the connection inclined-plane 8 of interface 7 tilts from inside to outside, and connection inclined-plane 8 ecto-entad of birdsmouth 6 tilts; The connection of adjacent piping lane 9,10, is equipped with wedge-shaped rubber sealing ring 11 between interface 7, birdsmouth 6; Described interface 7, the connection inclined-plane 8 of birdsmouth 6, the angle of inclination d of their complementations is 3.5 °.
