Abstract
The utility model relates to plastic drain-pipe, particularly relates to the anti-floating system of plastic drain-pipe.The anti-floating system of a kind of plastic drainage pipeline in Foam lightweight soil, described plastic drain-pipe is laid on bottom layer foam light soil, it comprises: the indented bars pair arranged along plastic drain-pipe, every double thread reinforcing bar divides and is listed in plastic drain-pipe both sides, and arrange in splayed, insert in bottom layer foam light soil bottom it, top iron wire colligation makes indented bars lock ring live plastic drain-pipe together.When the utility model can suppress to build Foam lightweight soil, gutter floats.
Description
Technical field
The utility model relates to plastic drain-pipe, particularly relates to the anti-floating system of plastic drain-pipe.
Background technology
The city of China is towards large-scale ultra-large type urban development, and Underground Rail Transit network is progressively shaping, and whole Urban Underground has spread all over subway tunnel.For the ease of construction, under having many situations, subway tunnel and ground level road overlap.This just has an impact to pavement of road maintenance.In order to reduce the impact on Subway Facilities structure, road construction demand fulfillment load " zero loads, zero off-load ", therefore roadbed changes to fill out and adopts light material and Foam lightweight soil, because Foam lightweight soil proportion is comparatively light, if directly build, the plastic drainage pipeline preset can float.
Summary of the invention
The utility model is intended to the defect overcoming prior art, provides the anti-floating system of a kind of plastic drainage pipeline in Foam lightweight soil.When the utility model can suppress to build Foam lightweight soil, gutter floats.
In order to solve the problems of the technologies described above, the anti-floating system of a kind of plastic drainage pipeline in Foam lightweight soil, described plastic drain-pipe is laid on bottom layer foam light soil, it comprises: the indented bars pair arranged along plastic drain-pipe, every double thread reinforcing bar divides and is listed in plastic drain-pipe both sides, and arrange in splayed, insert in bottom layer foam light soil bottom it, top iron wire colligation makes indented bars lock ring live plastic drain-pipe together.
The utility model can fixed plastics drainage pipe, when Foam lightweight soil is built, improves the stability of pipeline, remains the accuracy of invert elevation (IE) in the process that pipeline is built in Foam lightweight soil.Simply, the engineering time is short, makes full use of field condition and operates for easy construction, instrument, avoid and repeat to do over again because pipeline location changes, avoid to a great extent operating personnel to this operation repeat construction, indirectly improve operating efficiency, respond well.

Fig. 2 is lateral view of the present utility model.
Detailed description of the invention
As depicted in figs. 1 and 2, the anti-floating system of a kind of plastic drainage pipeline in Foam lightweight soil, described plastic drain-pipe 4 is laid on bottom layer foam light soil 1, it comprises: the indented bars 2 arranged along plastic drain-pipe is right, every double thread reinforcing bar divides and is listed in plastic drain-pipe both sides, and arrange in splayed, insert in bottom layer foam light soil bottom it, top iron wire 3 colligation makes indented bars lock ring live plastic drain-pipe together.
