Description

A kind of cave type prefabrication and assembly construction pipe gallery and installation method
Technical field
The present invention relates to underground pipe gallery field, specially a kind of cave type prefabrication and assembly construction pipe gallery and installation side Method.
Background technology
With the fast development in city, the problem of causing " road slide fastener ", is more and more severeer, is increasingly influencing civic just The often aesthetic feeling of life and city.In order to the various overhead lines of successive elimination street cobweb formula, urban ground landscape is made to become Finer, city integrated piping lane comes into being.City integrated piping lane is electric power, communication, radio and television, water supply, draining, heat The municipal pipelines such as power, combustion gas are all included, concentrate laying, play the role of " heart " in Modern Urban Development, can Urban carrying capacity is effectively improved, the development process in city is promoted.
Since the 1950s, the research of prefabricated assembled pipe gallery has been set about in China.But due to prefabricated structure The reasons such as the seam crossing sealing performance of part is poor, and drainage happens occasionally, in a very long time after this, prefabricated dress Construction with formula pipe gallery is just nearly at dead state.
And at this stage, in the process of city integrated piping lane development, precast splice type pipe gallery is obtained because of its superiority It is fast-developing.Many problems are also encountered simultaneously, if structure type is excessively complicated, are unfavorable for prefabrication;Gap is excessive, waterproof Effect is poor or because of prefabricated components heaviness, the problems such as being unfavorable for transporting.The above various reasons limit precast splice type integrated pipe The development of corridor technology, so being badly in need of a kind of generation for the novel precast splice type pipe gallery overcoming problem above.
Invention content
Hold for prefabricated assembled pipe gallery globality existing in the prior art and stability difference and waterproof system The problems such as easily collapsing, a kind of cave type prefabrication and assembly construction pipe gallery of present invention offer and installation method, the prefabricated assembled synthesis Pipe rack form is simple, facilitates prefabrication, is readily transported, and utilizes the excellent globality of cave type prefabrication and assembly construction pipe gallery And stability, waterproof effect etc. performance can be more preferable.
The present invention is to be achieved through the following technical solutions:
A kind of cave type prefabrication and assembly construction pipe gallery includes by the prefabricated curved roof of water-proof concrete, partition board, bottom plate And cradle;
The free end of the curved roof is overlapped in the groove of corresponding partition board top setting, is poured by water-proof concrete solid It is fixed;The bottom of the partition board is plugged in cradle pours fixation by water-proof concrete;Bottom is determined in the cradle setting Plate upper end and composition integrated member;
Curved roof, partition board and the bottom plate and cradle composition integrated member, respectively from top, both sides and Lower part is surrounded to form a tube coupling, and tube coupling connects to forming piping lane successively.
Preferably, the curved roof is formed by water-proof concrete through prefabrication, and internal arrangement upper layer and lower layer is equal In the reinforced mesh of criss-cross fashion.
Further, the curved roof uses domes, the reinforcing bar of double steel bar mesh sheet respectively curved roof from It is stretched out by end.
Preferably, the partition board includes being located at the outermost left clapboard of piping lane and right clapboard, and/or be located in the middle part of piping lane Middle partition board;The top of left clapboard and right clapboard extends inwardly, the prefabricated formation groove in top;Prolong to both sides on middle partition board top It stretches, and groove is formed at top, fixation is poured for both sides curved roof overlap joint grouting behind shaft or drift lining.
Preferably, overlapped curved roof quantity is corresponded at the top groove of the partition board, is provided with double amount Reinforcing bar stretches out.
Further, the length that reinforcing bar stretches out prefabricated component is 6-8 ㎝.
Preferably, the depth of groove at the top of partition board is 18-22 ㎝;Curved roof insertion partition board top groove depth be 12-14㎝。
Preferably, the prefabricated component is using additive water-proof concrete, fibre crack-resistance water-proof concrete, high performance water proof Concrete or ultra-high performance concrete are prefabricated.
Preferably, the bottom flute profile support outer slope surface angle is 65 ° -70 °, and inside slope surface angle is 3 ° -5 °;Bottom The vertical height of portion's cradle is not less than 1/10th of divider height.
A kind of installation method of cave type prefabrication and assembly construction pipe gallery, includes the following steps:
Step 1, using by cradle and bottom plate form integrated member as the bottom of pipe gallery arrange ground it On;
Step 2 is lifted on pipe gallery partition board within corresponding bottom cradle, between cradle and partition board Gap carried out pouring fixation with water-proof concrete;
Step 3 lifts curved roof, is overlapped on the groove at the top of respective sides partition board, in the anti-water coagulation in gap Soil cast is fixed, and the installation of the tube coupling is completed;
Step 4, repeat step 1 to three be sequentially completed phase union formed piping lane.
Compared with prior art, the present invention has technique effect beneficial below:
It is whole that the present invention by curved roof, partition board and bottom flute profile abutment member is connected to become one by slip casting measure Body has superiority outstanding using the section form of northern Shensi cave dwelling in terms of structural stability and water resistance.Its interval Plate is embedded on cradle, and then slip casting forms an entirety, to make its molding entire tube coupling not have gap, institute With material and water-proof concrete, so waterproof effect is more preferable.As long as bottom cradle and bottom plate are prefabricated into the cabin number of needs Specification, top can form the city in the single cabin needed, double cabins, the even more cabins in three cabins by installing partition board and curved roof Pipe gallery, it is versatile and flexible, it is easy for installation.The water-proof concrete component that the present invention uses all is prefabrication, assembled in situ group Dress, then fill and starch, economical rationality, component making is simple, light, is convenient to transport, the efficiency of work progress can obtain pole Big to improve, construction quality is controllable.
Further, the domed structure of curved roof, pours with partition board and builds up an entirety, and domes can be good at holding Carry the compressive loads such as the top soil body.
Further, it is in 65 ° -70 ° of slope angle on the outside of cradle, partition board " can be blocked " well, enhance its stability.
