Description
Technical field
The present invention relates to drainpipe technical field, more particularly to a kind of construction method of HDPE plastic-steel-wound drainage pipes.
Background technology
Drainpipe refers to rain pipe, the sewage pipe for being no more than 0.1MPa for internal water pressure, by design calculating and spy
In the case of other process, pressure water or power cables pipe etc. can be used for.
HDPE plastic-steel-wound drainage pipes have many advantages, such as that corrosion-resistant, light weight, simple installation, through-current capacity be big, long lifespan, can
For substituting high energy consumption material(Cement, cast iron, glass reinforced plastic pipe, ceramics etc.)The tubing of making belongs to environment-friendly product.
Existing HDPE plastic-steel-wound drainage pipes are mostly as shown in attached drawing 1 and Fig. 2 comprising an inner tube 24 and spiral shell
Rotation is wrapped in the outer tube 25 outside inner tube 24.
Since HDPE plastic-steel-wound drainage pipes are compared with tubing more rigid than cement, cast iron etc., there is lighter weight, non-deformability
Weaker feature is easy when drainpipe is embedded to underground deep place because excessive be deformed that be pressurized is caused to leak or be destroyed.
Invention content
The object of the present invention is to provide a kind of construction methods of HDPE plastic-steel-wound drainage pipes, can promote HDPE plastic-steels and twine
Around the anti-pressure ability of drainpipe, to make HDPE plastic-steel-wound drainage pipes can adapt to the installation of underground deep place.
The present invention above-mentioned technical purpose technical scheme is that:
A kind of construction method of HDPE plastic-steel-wound drainage pipes, includes the following steps:
S1:It carries out channel excavation and channel bottom will be tamped;
S2:It is laid with cement screed-coat to channel bottom and the supporting rod being supported to drainpipe is set in cement screed-coat,
The supporting rod is symmetrically inclined at the both sides of drainpipe, and along drainpipe move towards spaced set have it is multiple;
S3:Drainpipe is sent into groove and the side wall of drainpipe is made to offset with supporting rod, and with mounted row in groove
Water pipe is spliced;
S4:Drainpipe is connected by heating shrinkage band or Electric thermal smelting belt;
S5:Soil backfills in groove;
S6:Tamp ground surface.
Using the above scheme, by the way that the supporting rod being supported to drainpipe is arranged in the trench, supporting rod setting is being arranged
The both sides of water pipe are supported drainpipe, and the pressure that drainpipe is subject to after soil backfills can be transferred to water by supporting rod
Mud screed-coat, while the pressure of the support force of the supporting rod of both sides and soil can form the force of triangle direction, Neng Gouyou
Effect avoids the deformation of drainpipe.
Preferably, the angle between bar supported on both sides is 120 °.
Using the above scheme, the pressure for giving drainpipe after soil backfill is power straight down, by collateral by two
Angle between strut is set as 120 °, can make being more uniformly stressed for drainpipe, reduces drainpipe local deformation situation
Occur.
Preferably, the butt junction that setting offsets with drainpipe on the supporting rod, the butt junction includes to inner tube side wall
The first abutting part to offset and the second abutting part to offset with outer tube wall, first abutting part and second abut
For the arcuate structure to fit with inner and outer tubes.
Using the above scheme, the first abutting part of arcuate structure and the second abutting part can increase the abutting with drainpipe
Face, to play preferably support effect.
Preferably, the supporting rod is provided with rubber pad on the outside of the first abutting part and the second abutting part.
Using the above scheme, rubber pad can avoid supporting rod from causing rigid damage to drainpipe.
Preferably, it is connected on the supporting rod and tightens rope.
Using the above scheme, it by tightening the design of rope, can will be arranged by tightening rope after drainpipe installs
Water pipe tightens, and avoids the loosening of drainpipe.
Preferably, the company that the both ends of the drainpipe distinguish the connection female end of outward opening expansion and are open to contract
Sub- end is connect, the connection female end of drainpipe can be socketed on the outside of the connexon end of adjacent row water pipe.
Using the above scheme, by the design of connection female end and connexon end, the connection of both sides drainpipe can be facilitated, from
And conveniently drainpipe is connected by heating shrinkage band or Electric thermal smelting belt.
Preferably, it is provided with sealing ring on the outside of the connection female end, the sealing ring is made of water uptake expansion material.
Using the above scheme, when water is overflowed from the gap between two drainpipes, the setting of sealing ring can absorb moisture
And expansion makes to fill up in the gap between two drainpipes, and water is made no longer to leak out.
Preferably, the junction of adjacent two drainpipes is provided with the compressing member for compressing sealing ring, the compressing member
Including the first contractile ring, the second contractile ring and by the connected compressor arm of the first contractile ring and the second contractile ring, described first receives
Contracting ring and the second contractile ring are socketed in respectively on the outside of two drainpipes, and compressor arm is pressed on the outside of sealing ring.
Using the above scheme, by being provided with compressing member, can make in leak sealing ring under the action of compressor arm more
It inwardly deforms upon well to filling chink;Other first contractile ring and the second contractile ring can be socketed in adjacent two rows respectively
The outside of water pipe can make compressor arm preferably compress sealing ring.
Preferably, it is additionally provided with S4.1 in S4 and S5:Drainpipe and catch-basin or bilge well junction preformed hole are carried out
Block, then pour into water into the drainpipe one end connected, check the drainpipe that connects whether leak.
Using the above scheme, the leakproofness of drainpipe can be checked, is made to avoid the drainpipe of leak from putting into
With.
Preferably, the groove is inverted trapezoidal shape.
Using the above scheme, it by setting groove to inverted trapezoidal shape, facilitates and is put into drainpipe into groove, when will be native
When earth is backfilled in groove, soil can roll into the bottom of drainpipe to facilitate the bottom of filling drainpipe by oblique side wall along groove
Portion keeps drainpipe more firm.
In conclusion the invention has the advantages that:
1. being fixed on the supporting rod of drainpipe by being respectively arranged in the both sides of the drainpipe in groove, make after installing
Drainpipe be not easy laterally and longitudinal movement, the phenomenon that can preventing drainpipe from loosening, while between the supporting rod of both sides
Angle be 120 °, enable to being more uniformly stressed for drainpipe, avoid drainpipe deformation and the leakage and destruction that generate;
2. being set as connection female end and connexon end by drainpipe both ends, connection female end is socketed in can be square on the outside of connexon end
Just the connection of adjacent two drainpipe, while connecting the sealing ring being arranged on the outside of female end and being compacted part compression, drainpipe can be avoided
There is leak caused by gap in junction.
