Description
Technical field
The present invention relates to pavement construction technical field, more particularly to a kind of cement-concrete road-surface groove-carving method.
Background technology
At present, in construction of cement concrete road surface, in order to reach technical bid of the related specifications about surface friction coefficient
Alignment request is, it is necessary to the cutting of the surface formation pitted skin or formation certain specification in cement concrete pavement, can thus reach road
The coefficient of friction technical standard in face, the pitted skin on road surface or cutting are entered using two methods in construction of cement concrete road surface at present
Row construction, one kind is that after cement concrete pavement has been flattened, intensity uses hairbrush or steel brush in concrete road before not formed
The surface in face forms pitted skin or cutting, and also a kind of way is after the intensity of cement concrete pavement is formed, using special
Cutting machinery forms cutting referred to as " hard cutting " on the surface on road surface, when being constructed using former approach, using hairbrush in cement
The pitted skin that concrete surface is formed, coefficient of friction does not often reach code requirement, is unfavorable for the safety of driving, does not reach road surface yet
Acceptance criteria, such as using steel brush formed cutting when, work progress brush teeth is easy to the rubble or the grains of sand in concrete to tick,
Make to be damaged in the local position short time for producing more serious pit and pitted skin, road surface to form pit and pitted skin after being open to traffic,
Must be repaired.When carrying out " hard cutting " construction using second method, because the sawblade-replacing of gaining machine is frequent, work is caused
Journey cost is increased substantially, and engineering cost increasing degree is larger, uneconomical.
The content of the invention
It is an object of the invention to solve at least the above, and provide the advantage that at least will be described later.
It is a still further object of the present invention to provide a kind of cement-concrete road-surface groove-carving method, it can be in cement concrete
Bar shaped lamellar body is embedded into during road surfacing, after the completion of road surfacing, bar shaped lamellar body is removed and is directly formed after repairing
Road surface cutting, construction is simple, easy to use；Lift and fix the cutting net of bar shaped lamellar body and can also improve cement retardative soil surface
Cracking resistance, extend road surface service life.
In order to realize these purposes of the invention and further advantage, there is provided a kind of cement-concrete road-surface groove-carving side

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
It should be appreciated that it is used herein such as " have ", "comprising" and " including " term do not allot one or many
The presence or addition of individual other elements or its combination.
As shown in Figure 1, 2, 3, the present invention provides a kind of cement-concrete road-surface groove-carving method, comprises the following steps：
Step one, laying sub-surface；
Step 2, the laying ground floor cement concrete layer on the sub-surface, afterwards on the part road for needing cutting
Cutting net is sequentially laid in section, the raised insertion ground floor cement concrete layer of the multiple set on the lower surface of the cutting net
In；
Step 3, even power roll the cutting net so that the part of cement of ground floor cement concrete layer is from the cutting
It is prominent in the hole of net, height of the projecting height less than the strip lamellar body on the upper surface of the cutting net；
Step 4, after ground floor cement concrete layer initial set after, one layer of the even application on the upper surface of the cutting net
PVC adhesives are not sprayed at PVC adhesives, and the strip lamellar body；
After step 5, spraying PVC adhesives 5-15min, second layer cement is laid on ground floor cement concrete layer mixed
Solidifying soil layer so that the radian of second layer concrete layer is adapted with the height of the strip lamellar body of the online end face of the cutting；
Step 6, after after the initial set of second layer cement concrete layer, the removal online strip lamellar body of cutting forms road surface and carves
Groove；
Step 7, with concrete sander to carrying out polishing finishing at the road surface cutting in step 6, afterwards with water rinse,
Make the road surface cutting of shaping accurately clear；
Wherein, cutting net includes web body 10, and it is the network structure being stamped and formed out by the lamellar body of PVC materials, and institute
State and set on the lower surface of network structure multiple raised 101, raised length is 2-5cm；The cutting net also includes multiple long
Bar shaped storage tank 102, it is integrally formed on the upper surface of the web body；Strip lamellar body 103, it is dismountable embedded
Be arranged in the multiple strip storage tank, and width and any bar strip storage tank of the strip lamellar body depth phase
Adapt to.

Also improve the roughness of the upper surface of the first cement concrete layer；In the first cement retardative soil layer and the surface spraying of cutting net
PVC adhesives so that the surface that the second cement concrete layer can be preferably with the first cement retardative soil layer and cutting net bonds
It is fixed, it is to avoid layering；After having laid the second cement concrete layer, part road surfacing, the equating of cutting net will be equipped with, with bar
Shape lamellar body is not covered as criterion by the upper surface of the second cement concrete layer, facilitates the later stage to remove bar shaped lamellar body；Further, since bar
Shape lamellar body is embedded to be arranged in multiple strip storage tanks, when removal bar shaped lamellar body, also will not sticky its periphery water
Cement concrete particle, protection road surface is complete, and construction effect is good, it is only necessary to substantially protruding and second cement concrete layer
The opening edge edge of multiple strip storage tanks carries out grinding process；And machine cuts before being construction due to cutting net,
Shaping is poured, multiple bar shaped storage tanks thereon can be with the combined and spliced pattern into various shapes, such as being parallel to each other in Fig. 2
Cutting, or such as square cutting in Fig. 4, enrich the shape of road surface cutting, extend its range of application.
In sum, the inventive method can be embedded into bar shaped lamellar body during paving cement concrete pavement, on road
After the completion of the laying of face, bar shaped lamellar body is removed and road surface cutting is directly formed after repairing, construction is simple, easy to use；Lift solid
Surely living the cutting net of bar shaped lamellar body can also improve the cracking resistance of cement retardative soil surface, extend the service life on road surface.
In a preferred scheme, the thickness of the ground floor cement concrete layer is no more than 22cm；And in laying first
