Abstract
An environment-friendly modular concrete tubular column is composed of a prefabricated reinforced concrete tube, building debris, cement mortar and prestressed reinforcement. A convex connecting section and a concave connecting section are arranged at the upper end and the lower end of the prefabricated reinforced concrete tube respectively. The prefabricated reinforced concrete tube is filled with the building debris, and the prefabricated reinforced concrete tube and the building debris are spliced to a whole by pouring the cement mortar. Concrete tubular column sections are connected through the convex connecting section and the concave connecting sections in an inserting mode. The prestressed reinforcement penetrates through reinforcement preformed holes of the concrete tubular column sections, and the concrete tubular column sections are connected by pouring the cement mortar. The environment-friendly modular concrete tubular column has the advantages that the building debris is reused, pollution and damage to the environment are reduced, and the use ratio of the land is improved; the usage amount of concrete is reduced, and cost is lowered; the concrete tubular column is prefabricated, the construction quality of the concrete tubular column body can be improved, construction speed can be improved, construction efficiency can be improved, and good economical efficiency and applicability are achieved.
Description
Technical field
The present invention relates to conventional rod structure design and construction technique, particularly a kind of environment-friendly type modularization concrete tubing string and construction method thereof in the construction such as bridge engineering, work China Democratic National Construction Association and ocean port works.
Background technology
At present, China is in infrastructure construction peak phase, and building renewal speed is very fast, has produced a large amount of building wastes, the concrete waste material, fragment of brick etc. that such as removing, produce.These building wastes are often piled up and are taken very large space, deal with cost higher again, are very stubborn problems of infrastructure process.On the other hand, along with large quantities of bridges, port and pier and some new builing structures drop into design and establishing successively, as the rod structure of supporting part, apply more and more extensive, but load-bearing pillar is as a kind of massive structure, concrete use amount is very large, occupies suitable ratio in general structure cost.
Summary of the invention
Object of the present invention is intended to for above-mentioned existing problems, a kind of environment-friendly type modularization concrete tubing string and construction method thereof are provided, and this concrete pipe rod structure novelty, can effectively reduce concrete use amount, reduce costs, adopt prefabricated component simultaneously, can greatly improve efficiency of construction, reduction of erection time.
Technical scheme of the present invention:
A kind of environment-friendly type modularization concrete tubing string, by prefabricated reinforced concrete pipe, building debris, cement mortar and prestressed reinforcement, formed, prefabricated reinforced concrete pipe is sleeve structure, on sleeve pipe annular space concrete perfusion in the middle loop wire, uniform steel bar preassembling is boxed out, and the upper and lower side of prefabricated reinforced concrete pipe is respectively equipped with convex linkage section and matrix linkage section; In prefabricated reinforced concrete pipe, insert building debris, by cement injection mortar, prefabricated reinforced concrete pipe and building debris are bonded as one, become a joint concrete tubing string; Between each joint concrete tubing string, by convex-concave linkage section plug-in type, connect and the steel bar preassembling of each joint concrete tubing string is boxed out and align; In prestressed reinforcement is boxed out through the steel bar preassembling of each joint concrete tubing string and by cement injection mortar, more piece concrete tubing string is connected, form environment-friendly type modularization concrete tubing string.
A construction method for described environment-friendly type modularization concrete tubing string, step is as follows:
1) by the building debris that comprises waste concrete block and waste bricks stone according to volume size rough classification, then hierarchical classification throwing enters in prefabricated reinforced concrete pipe, first throwing large volume discarded concrete, then fills the fragment of brick of smaller size smaller and stone to fill the space between large volume waste material skeleton;
2) the good cement mortar of perfusion workability, makes a joint concrete tubing string;
3) second section prefabricated reinforced concrete pipe is lifted on the concrete tubing string making, by convex-concave linkage section plug-in type, connects and the steel bar preassembling of each joint concrete tubing string is boxed out and align, repeat above-mentioned two steps and make second section tubing string;
4) repeating step 3) until all after installation, at box out inner stretch-draw prestressing force reinforcing bar more piece concrete tubing string being connected by cement injection mortar of the steel bar preassembling of each joint concrete tubing string, form environment-friendly type modularization concrete tubing string.
Advantage of the present invention is: by the recycling to building debris, solved the processing problem of a large amount of building debriss that produce in building construction process, reduced pollution and destruction for environment, minimizing takies the soil body, has improved land use rate; Reduced concrete use amount simultaneously, reduced costs; Prefabricated by concrete pipe rod structure, can improve concrete pipe cylinder construction quality, accelerate speed of application, improve efficiency of construction, there is good economy and applicability.
