Description
Technical field
The invention belongs to technical field of roadway maintenance, further to energy-efficient bituminous pavement recovery technique, specifically
It is related to repair technology after pit slot detects.
Background technique
Road surface pit slot (pot holes) refers in the case where driving acts on, road surface aggregate local shedding and the hollow that generates, is
The Common Diseases that bituminous pavement is easily sent out multiple influence travel safety, comfort and appearance of a street road looks.If maintenance is too late
When, great threat can be constituted to traffic safety, while the increase of maintenance cost can be aggravated.Existing pit repairing, generally follows
Be that circular hole side is mended, the principle that oblique hole is just being mended makes maintenance surface be rectangle, and surrounding is parallel or vertical with pavement strip, if range
It can be expanded around according to surface disease actual range.
But such traditional cutting mode, because cut coverage is that staff judges to combine working experience by naked eyes
Come what is carried out, the shape and size of cutting are lack of standardization, cause the quality filled up that can not unify, if the range of cutting compares
Greatly, the construction time is on the one hand not only increased, on the other hand, needs a large amount of virgin material to fill up pit slot, to the specification and skill of equipment
Art requirement is also relatively high, even if the prior art can carry out part processing to the pitch cut down and recycle, but salvage material
Properties be to be markedly less than virgin material, probability that this results in the position repaired with reclaimed materials to occur disease after it again is remote
Greater than the position repaired with virgin material.
Summary of the invention

Detailed description of the invention
Fig. 1 is the position view of groove of the present invention and cutting line,
Fig. 2 is the structural schematic diagram of dashpot of the present invention.
Figure number and title: 1, pit slot, 2, groove, 3, cutting line, 4, dashpot.
Specific embodiment
By the technology contents that the present invention will be described in detail, construction feature, reached purpose and efficacy, hereby enumerates embodiment below
And it is explained in detail in conjunction with Figure of description.
Repair technology after a kind of detection of pit slot, comprising the following steps:
1, the spacing a for measuring pit slot 1 bottom bosom and road surface is arranged a light barrier in the surface of pit slot, guarantees
A darker state is in pit slot, then pit slot edge put vertically next light source (cannot be excessively high or too low, should
Guarantee that light source can be subject to the direction of relative level and shine most of pit slot bottom), it at this time only can there are two types of positions yin occurs
Shadow: protrusion or recess, raised shade appear in the side of its backlight, and the shade of recess then appears in recess, utilizes work
Industry camera records these shadow positions；Light source is put down vertically in another place position in pit slot edge, also utilizes industrial phase
Machine records these shadow positions in the same angle of same position；The shade recorded twice is compared, because of light source
Position changed, so necessarily biggish change can also occur for the shade of protrusion, but the shade of groove changes very little,
Therefore the part for recording overlapping twice is the position of pit slot sunken inside, the depth being finally recessed using laser range finder to everywhere
Degree measures, and taking maximum value therein is the spacing a on pit slot bottom bosom and road surface, without to entire pit slot bottom
Portion carries out blanket type measurement；
2, the length of each part in part of pit slot 1 side wall to convex is measured, and calculates its average length
It 3, will be to the length of convexPart select, the endpoint of selected part is subjected to line, in pit slot 1
The groove 2 that depth is b is outputed along these lines in bottom surface；(as shown in Figure 1, pit slot one shares A, B, C, D, E five to convex
Part, but because D is less than average length to the length of convex, only with connection A, B, C, E)
4, determine that the position of d (length at the corresponding pit slot edge of > groove) determines one outside each groove 2
Cutting line in parallel extends outwardly at the both ends of each cutting line until intersecting, these cutting lines and intersection point, that is, structure
At cutting track；
5, carrying out depth along cutting track using cutting equipment is h1(h1=a+b) cutting, it is remote in each cutting line
It is h that side from selected part, which offers depth,2(h2=dashpot a), the section of dashpot is that apex angle is (α=30 °) α
Right angled triangle；(as shown in Fig. 2, being equipped with dashpot, a side in its side far from pit slot after the processing for completing cutting line
Face guarantees the inner wall that pit slot will not be damaged in subsequent shattering process, on the other hand during last filler pit slot edge it is oblique
Face can make filler cooling more evenly, guarantee the effect of pit slot filling.)
6, the part between groove and cutting track is crushed, broken sequence is right since the end of selected part
Backward cutting line direction is mobile, grinding depth a≤h3≤a+b；
7, broken ground surface material is subjected to recycling and is reprocessed into reclaimed materials, while the bottom surface of pit slot flattened, leveling
The depth h of pit slot afterwards4=a+b；
8, the reclaimed materials that height is c (c < a+b) will be first laid in pit slot, waiting reclaimed materials hardening after compacting leveling, to
The appropriate virgin material of supplement in pit slot, the height of virgin material are a+b-c；
9, can be open to traffic after it being waited to harden after virgin material compacting leveling.
To sum up, only the preferred embodiments of the invention, is not limited the scope of protection of the present invention with this, all according to the invention patent
Equivalent changes and modifications made by range and description are all within the scope of the invention patent covers.
