Description

Ubbase drain blind ditch construction technique on the road surface TST
Technical field
The present invention relates to ubbase drain blind ditch construction works on the processing technique of discharge pavement seepage more particularly to the road surface TST Skill.
Background technique
Highway drainage french drain is mostly that underground water or earth's surface infiltration is discharged, and is constructed mostly in highway construction, longitudinal drainage, if It sets in cutting excavation section.
Discovered in recent years, many highways in operation occur road surface transverse crack at filled-up ground after rainfall and emit water The phenomenon that.The main reason is that Atmospheric precipitation is penetrated into pavement layer structure by reflection cracking in a pavement, and in road surface structare layer It flows along road longitudinal grade, is flowed out from reflection cracking in a pavement in the effect of itself water pressure and vehicular load from high to low.
Conventional highway drainage french drain, can not be discharged the water in road surface structare layer, cause the pavement structure long period full It works under water state, causes pavement structure depression of bearing force, occur purt mud etc. under vehicle repeated action, exacerbate pavement disease Development, seriously affected the service life and service level on road surface.
Heavy resurfacing engineering excavates pavement structure, and open as used traditional new highway weeper drain with needing depth It is larger to dig area, complex process, heavy workload, inconvenient, long construction period of constructing, road surface will appear new-old pavement not after construction The diseases such as uniform settlement, gaping of joints, and the prior art is the water being discharged under sub-surface, cannot be discharged in sub-surface Pressure water, cause in this way be discharged pavement seepage speed it is slow.
Summary of the invention
For the deficiency of conventional discharge french drain function, the present invention provides ubbase drain blind ditch construction work on a kind of road surface TST Skill.
The technical scheme to solve the above technical problems is that ubbase drain blind ditch construction technique on the road surface TST, packet Cutting notch, laying rubble, placement steel plate, coating adhesive, TST melten gel, superficial layer construction, kerbstone aperture and earth shoulder is included to change Fill out 7 technique of rubble;
1, it cutting fluting: according to pavement crack position and disease range, determines reasonable groove width and crosses and demarcate Cutting position is cut along scribing line with grooving machine, cuts 4 altogether, and outside twice depth of cut is identical as supercrust thickness, centre two Road ratio outside depth 5cm, the cavity after clearing up fluting.
2, it is laid with rubble: rubble is layered in base's slot.
3, it places steel plate: the steel plate of the 4mm thickness of antirust paint will be coated with, be laid in substrate top surface.
4, coating adhesive: the TST melten gel after fusing is equably applied to the bottom of bituminous pavement notch by fusing TST melten gel Portion and two sides.
5, TST melten gel: the hard limestone gravel that selection has corner angle, embedded squeezing good, it is desirable that crush values are not more than 30%, needle Sheet content has good gradation between 15~20%, and stone cleaning, stirring, heating pour into the TST of 21O DEG C of flowing Material, is stirred, the mixture laying stirred evenly is in slot and is compacted.
6, superficial layer is constructed: being allowed to sufficiently bond with the TST melten gel of heat with blowtorch heating TST melten gel top surface, at TST melten gel It manages width and exceeds each 2cm in notch two sides.
7, kerbstone aperture and earth shoulder, which change, fills out rubble: the kerbstone aperture of corresponding site, earth shoulder locally change and fill out rubble.
The beneficial effects of the present invention are: excavation area is smaller, simple process, workload is small, and construction equipment is few easy to operate, It is convenient to construct, short construction period, and new-old pavement seam will not cracking after construction, and emphasis is the water being discharged in sub-surface, makes to arrange Pavement seepage speed is accelerated out.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the temperature of stone heating is 100~150 DEG C.
Further, expect according to TST: rubble=1: 9 ratio mixing.
The beneficial effects of the present invention are: improving construction precision.
Detailed description of the invention
Fig. 1 is schematic diagram of the present invention;
In the accompanying drawings, list of designations represented by each label is as follows: 1, TST melten gel;2, bituminous pavement;3, rubble; 4, steel plate;
Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and It is non-to be used to limit the scope of the invention.
As shown in Figure 1,1. cutting flutings;According to pavement crack position and disease range, reasonable groove width is determined simultaneously Cutting position has been demarcated in scribing line, is cut with grooving machine along scribing line, outside twice depth of cut is identical as surface thickness, intermediate twice Than outside depth 5cm, cavity after cleaning fluting makes every effort to guarantee that smooth draining is smooth not to accumulate to protect for cavity bottom and the right and left Water.
2, it is laid with rubble 3: the mono- graded broken stone 3 of nominal maximum particle diameter 8mm is layered in base's slot.
3, it places steel plate 4: the steel plate of the 4mm thickness of antirust paint will be coated with, the width of steel plate is determined according to base's groove width, generally It is 30~40mm bigger than base groove width, it is laid in substrate top surface.
4, coating adhesive: by the TST melten gel 1 after fusing equably in the bottom and two sides of 2 notch of bituminous pavement.
5, TST melten gel: the hard limestone gravel that selection has corner angle, embedded squeezing good, it is desirable that crush values are not more than 30%, needle Sheet content has good gradation between 15~20%.Stone must be cleaned, stirs, be heated, and pour into 21O DEG C immediately The TST melten gel 1 of flowing, is stirred, and the mixture stirred evenly quickly paves in slot and is compacted.
6, superficial layer is constructed: making it sufficiently to bond with the TST melten gel of heat with blowtorch heating TST melten gel top surface, TST melten gel It handles width and exceeds each 2cm in notch two sides.
7, kerbstone aperture and earth shoulder, which change, fills out rubble: the kerbstone aperture of corresponding site, earth shoulder locally change and fill out rubble, French drain is set continuously swimmingly to flow out pavement structure to guarantee that water energy is enough.
The temperature of stone heating is 100~150 DEG C.
Expect according to TST: rubble=1: 9 ratio mixing.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
