Abstract

The invention relates to a treatment method of an expansive soil channel and aims to provide the treatment method of the expansive soil channel which is quick and convenient to construct, better in deformation adaptability and convenient to maintain later. Moisture exchange of expansive soil and the outside is reduced, significant change of moisture content of the expansive soil is avoided, the slope stability is improved, and better social and economic benefit is realized. According to the technical scheme, the treatment method comprises steps as follows: 1, composite geo-membranes are laid on a bottom plate of the channel and channel slopes on two sides and extend to tops of the slopes on two sides of the channel accordingly; 2, dry stones are laid on surfaces of the composite geo-membranes in the channel; 3, grouted rubble stop ridges are arranged at the tops of the slopes on two sides along the channel, PVC (polyvinyl chloride) drainage pipes inclining towards the inside of the channel are arranged inside the grouted rubble stop ridges at intervals of 3 m; 4, grouted rubble presses and covers upper parts of the composite geo-membranes at the tops of the slopes on two sides of the channel; 5, the two sides along the channel are filled with excavated materials doped with sand gravel, and non-expansive soil materials are laid on surface layers of filled areas.

Description

A kind of administering method of expansive soil channel
Technical field
The present invention relates to the construction time of the administering method of a kind of expansive soil channel, particularly expansive soil channel and runtime, adopt the administering method of the expansive soil channel of composite geo-membrane+loose stone pavement structure.Being primarily adapted for use in geological conditions is the engineering channels such as the diversion of swelled ground, water supply.
Background technology
Swelled ground is because of himself special dilatancy, many fissurities and overconsolidation, and after channel excavates, water content is very easily deformed after changing destroying.The endogenous cause of ill of expansive soil canal slope failure is that the soil body has stronger swell-shrink characteristic and grows the crack of growing up (or interlayer Weak face) having certain density, as shallow phenotype creep and slip of collapsing are destroyed all closely related with soil expansion;Deeper is slided and is then depended on the development degree of structural plane in the soil body.The exopathogenic factor of expansive soil canal slope failure is mainly after the soil body is exposed to ground surface environment and occurs drying and watering cycle, surface water immersion, excavation off-load and precipitation infiltration or surface water (including water in a canal) to infiltrate, Infiltration water not only can soften structural plane, cause structural plane end stress to concentrate, it is also possible to directly produce hydrostatic thrust in trailing edge drawing crack face.
The improvement of domestic and international expansive soil channel, substantially includes protection and processes two aspects.Protection to channel, is take effective measures, and makes channel basis not produce excessive shear stress or deformation and produce to destroy;Channel is processed, refers to occurring the canal slope destroyed to carry out rationally repairing reliably and reinforcing.Most expansive soil channel all occurred after being completed destroying the problem repaired again.
Summary of the invention
The technical problem to be solved in the present invention is: for above-mentioned existing problems, there is provided one construction quick, easy, adaptive deformation ability is better, and the administering method of the convenient expansive soil channel of later stage maintenance, utilize the anti-seepage effect that composite geo-membrane is good, reduce the exchange of swelled ground and outside moisture, avoid the notable change of swelled ground water content, simultaneously by loose stone mask, increase slope stability, play good economic results in society.
The technical solution adopted in the present invention is: the administering method of a kind of expansive soil channel, it is characterised in that comprise the following steps:
1, laying composite geo-membrane at channel base plate and both sides channel side slopes, and postpone to channel two side slope top, top, slope laying length is less than 1m;
2, in channel, the surface of composite geo-membrane builds loose stone, thickness 30cm by laying bricks or stones;
3, top, channel along both side slope arranges cemented rock gear bank, cemented rock gear bank top exceeds loose stone mask top 30cm, arrange the PVC drain pipe of a caliber 100mm in cemented rock gear bank every 3m, in drain pipe tendency channel, drain pipe end is surrounded by anti-filter geotextiles;
4, the composite geo-membrane top on channel two side slope top covers cemented rock;
5, channel is along both side, utilizes the excavated material mixing sand gravel to fill, and unexpansive earth material is laid on top layer, reclamation district.
The unexpansive earth material of step 5 is arranged builder's road.
The invention has the beneficial effects as follows: the present invention feature according to expansive soil channel construction time and runtime, the administering method of a kind of expansive soil channel adopting composite geo-membrane+loose stone pavement structure is provided, utilize composite geo-membrane easy construction, can the feature of once-paving canal segment length, swelled ground after quick closure excavation is domatic, decreases the evaporation of swelled ground basis moisture content;And the performances such as the antiseepage of composite geo-membrane, tension and anti tear are all better, and engineering adaptability is strong;Loose stone is built on composite geo-membrane surface by laying bricks or stones, using the teaching of the invention it is possible to provide certain ballast, it is suppressed that the deformation of swelled ground.
Accompanying drawing explanation
The structure that Fig. 1 is the present invention arranges schematic diagram.
Detailed description of the invention
As it is shown in figure 1, the feature that the present embodiment is according to expansive soil channel construction time and runtime, it is provided that the administering method of a kind of expansive soil channel adopting composite geo-membrane+loose stone pavement structure, it is adaptable to geological conditions is the engineering channels such as the diversion of swelled ground, water supply.
In the present embodiment, expansive soil channel 8 includes channel base plate 8-1 and both sides channel side slopes 8-2, lays composite geo-membrane 1 at channel base plate and both sides side slope, and postpones to channel two side slope top;In channel, loose stone 2 is built on composite geo-membrane surface by laying bricks or stones, and top, channel along both side slope arranges cemented rock gear bank 3, and every the PVC drain pipe of 1 caliber 100mm of 3m cloth in gear bank, in drain pipe tendency channel, end is surrounded by anti-filter geotextiles;Composite geo-membrane 1 top, top, slope covers cemented rock 7;Channel along both side, according to landform needs, can utilize excavated material 5 (mixing sand gravel) to fill, and unexpansive earth material 4 is laid on top layer, reclamation district;The builder's road 6 of channel needs to lay on unexpansive earth material in combinations with hillside draining.
The concrete construction method of the present embodiment is as follows:
1, laying composite geo-membrane 1 at channel base plate 8-1 and both sides channel side slopes 8-2, and postpone to channel two side slope top, top, slope laying length is less than 1m, it is prevented that channel periphery earth's surface is oozed under water;
2, in channel, the surface of composite geo-membrane 1 builds loose stone 2, thickness 30cm by laying bricks or stones;
3, top, channel along both side slope arranges cemented rock gear bank 3, cemented rock gear bank top exceeds loose stone 2 mask top 30cm, arrange the PVC drain pipe of a caliber 100mm in cemented rock gear bank 3 every 3m, in drain pipe tendency channel, drain pipe end is surrounded by anti-filter geotextiles;
4, composite geo-membrane 1 top on channel two side slope top covers cemented rock 7;
5, channel is along both side, according to landform needs, can utilize and mix the excavated material 5 of sand gravel and fill, and unexpansive earth material 4 (such as Modified soil, scoria etc.) is laid on top layer, reclamation district, and thickness is 30cm.
Need in conjunction with hillside draining, the unexpansive earth material 4 of above-mentioned steps 5 is arranged builder's road 6.
