Abstract
The invention provides a construction method for fixing an HDPE (high-density polypropylene) pipe by embedding iron wires. Machine bricks are embedded and the iron wires with sufficient lengths are bound during concrete flat foundation construction before concrete is wrapped on the municipal drain pipe, and the HDPE pipe is firmly bound by the embedded iron wires after being laid. The construction method sequentially includes particular steps of laying out for measurement; excavating a groove; embedding the machine bricks, binding the iron wires, and pouring to form a concrete flat foundation; laying the pipe; checking tightness; binding the HDPE pipe by the iron wires; and wrapping the pipe by the concrete. The iron wires are embedded when the flat foundation of the flexible municipal drain pipe is poured, and the pipe is fixed by the embedded iron wires after being arranged in place, so that the construction precision is guaranteed, the flexible pipe is prevented from moving when the concrete is poured, and rework caused by movement of the pipe is stopped. The construction method has the advantages of high safety, firmness, reliability, convenience and speediness in construction and high economical efficiency. Besides, the mounting quality of the pipe is effectively guaranteed, and the method guarantees that the pipe is mounted and is wrapped by the concrete at one step.
Description
Technical field
The present invention relates to a kind of urban construction project job practices, specifically the fixing HDPE pipe construction method of the pre-buried iron wire of a kind of municipal drainage pipeline flexible pipe.
Background technology
According to the engineering of building up in the past, HDPE pipeline coagulation mount pipe by traditional construction technology, the pipeline rising phenomenon very easily occurs during pouring concrete, need to do over again, and causes simultaneously the waste of people, material, machine, has increased construction cost.Along with the development of my incorporated business, the technology of construction, method, level all at waxing development year by year, are improved job practices consciously, have formed " pre-buried iron wire is HDPE pipe construction method fixedly ".This method is simple, successful.The pipeline rising phenomenon very easily occurs when using the method mainly to solve the cast of HDPE pipeline coagulation mount pipe concrete, greatly reduced the significant wastage of finishing process in the work progress and people, material, machine.
Summary of the invention
The invention provides fixedly HDPE pipe construction method of a kind of high safety, the front pre-buried iron wire of municipal drainage pipeline flexible pipe pouring concrete solid and reliable, convenient and quick construction economy.
The present invention is achieved through the following technical solutions:
A kind of pre-buried iron wire is HDPE pipe construction method fixedly; it is characterized in that: the iron wire of pre-buried machine brick and the good sufficient length of colligation when the municipal drainage pipeline concrete is assured the flat base construction of front, concrete; after the HDPE pipeline laying is good; it is fastening with pre-buried good iron wire the HDPE pipe to be carried out colligation; the HDPE pipe is not subjected to displacement when guaranteeing that concrete is assured, and the Specific construction step is as follows: measure setting-out → channel excavation → embeded machine brick tie wire, the flat base of concrete cast → pipeline laying → seal check → iron wire colligation HDPE pipe → concrete is assured.
Spacing between the described iron wire is 1m.
The invention has the beneficial effects as follows: the present invention is pre-buried iron wire when municipal flexible water drainage pipe plane base cast, pipeline is in place to utilize pre-buried iron wire to be fixed afterwards, guarantee construction precision, prevent that flexible duct from producing displacement in concrete placement, the problem of pipeline come-up and in-plane displancement is stopped the phenomenon of doing over again that produces because of the tubing displacement in the time of can effectively avoiding assuring pouring concrete.Job practices of the present invention is workable, easy and simple to handle, technical difficulty is little, and pipeline process installation quality is controlled easily, has improved efficiency of construction; Pipeline once mounting qualification rate is high, has reduced the phenomenon of doing over again that pipeline is installed, thereby has saved the expenditure of plant equipment and labour cost; This construction technology compared with prior art has high safety, solid and reliable, convenient and quick construction, both economical characteristics, has effectively guaranteed the pipeline installation quality, has guaranteed that pipeline is installed to assure once with concrete to survive.Adopt the construction of this method method, the bright dew time shorten of groove has reduced the dust discharging, reduces traffic and ambient influnence, is conducive to civilized construction; Along with the extensive use of HDPE pipeline, the present invention will better be implemented, and obtain preferably social benefit.Job practices of the present invention should be used in the flexible water drainage pipe works of city.
