Description
Technical field
The present invention relates to embankment drainage system field, and in particular to highway pavement occur pit, cracking, differential settlement,
It is a kind of without excavating during the phenomenons such as the rainwater that fracture and the rainwater in embankment, capillary water and median strip can not be drained completely
And the embankment transverse drainage construction method that can be recycled.
Background technology
With the fast development continued to develop with traffic science technology of communication, the quality and quantity of highway is all being carried
Height, while also increasingly pay attention to the drainage works of highway, the also more and more higher of the requirement to it.And traditional roadbed transverse drainage
Facility, is the setting transverse drainage duct at roadbed top, to discharge the infiltration of median strip collected, this drainage pattern without
Method solves to pass through the moisture that median strip, earth shoulder, side slope etc. have been seeped into inside embankment, can not also discharge wet soft section road
Capillary water in dike；Also there is the push pipe mode using no-dig technique to construct now, draining effect duration after draining, but its construction
Short, often the water after the time of 1 year or so in drainpipe just can not discharge the drainpipe, it is necessary to more renew, cost due to blocking
It can therewith increase, also increase the workload of road maintenance workman.
The content of the invention
There is provided a kind of without excavating and recyclable making it is an object of the invention to overcome the deficiencies in the prior art
Embankment transverse drainage construction method.
The technical proposal of the invention is realized in this way：
A kind of embankment transverse drainage construction method, it is characterised in that construction method is as follows：

Step 7）, install soakaway trench, three-dimensional porous resin filter element：Soakaway trench, three-dimensional are selected into hole length according to drilling rod
Porous resin filter core, installs the soakaway trench of a caliber caliber bigger than soakaway trench at away from hole mouthful 0.5m, wherein, described infiltration
The pipe for D90mm or D110mm is managed, the pipe of a corresponding big caliber is D100mm or D120mm pipe, the pipe work of a big caliber
For the sealer between hole and soakaway trench, by soakaway trench jacking hole；
Step 8）, closing：Hole is made into Seal treatment with mortar or C15 concretes；Wherein, the proportioning of every cube of mortar is
Cement：Sand：Water=242：1655：270, the proportioning of every cube of C15 concretes is cement：Sand：Water：Stone=185：247：768：
1200；
Step 9）, cleaning job site：After hole closing terminates, the construction rubbish of cleaning job site, dismounting machinery,
Bracket track, is moved to next hole position and continues to construct；
Step 10）, embankment moisture content is detected after two weeks to one month again, such as moisture content is less than the optimal of detection area and contained
Water rate, then engineering terminate；Optimum moisture content such as moisture content higher than detection area, then according to step 2）Again continue with.
Step one）Described in medium grained sand for particle diameter be more than 0.25mm granular mass exceed gross mass 50% sand.
Step one）Described in mixing water be drinking water.
The positive effect of the present invention is：1st, have a wide range of application, filled out suitable for Expressway Embankment, median strip and height
The national highway and provincial highway of side；
2nd, easy construction, the cycle is short；Traditional drainage construction, which sets up support with steel pipe, needs 2h, and bracket track integration is only
Need 55min；Total engineering time shortens 1.5h than conventional construction method；
3rd, traffic will not be blocked, greenery patches vegetation is not destroyed；
4th, engineering cost is low, and three-dimensional porous resin filter element can filter the impurity in draining, reaches permanence operation, when
Between longer cost advantage it is more obvious；And in traditional drainage and construction method, the steel pipe for setting up support weares and teares meeting constantly for a long time
Reduce, the congestion of tubing all can be cost increase.
