Abstract
The invention relates to a cement concrete subgrade protective base plate and a technology. The cement concrete subgrade protective base plate comprises a protective base plate body, wherein a plurality of cracks are formed in the surface of the protective base plate body; drainage grooves corresponding to the cracks are formed in the protective base plate body; the cracks are communicated with the drainage grooves. According to the protective base plate provided by the invention, during the concrete subgrade pavement process, the cracks guide the concrete cracking direction, so that the cut cracks extend to the cracks in the protective base plate, rainwater flows to the cracks of the protective base plate along the cracks of the concrete subgrade, and is discharged through the drainage grooves, and the service life of the concrete subgrade is further effectively guaranteed.
Description
Technical field
The present invention relates to rigid pavement technical field, specifically, relate to a kind of cement concrete roadbed protective pad plate and technique.
Background technology
Cement concrete pavement is widely used in the highways and streets of China, airfield pavement, slip-road and mountain road, has the features such as intensity is high, good stability, good heat resistance, skid resistance are good, maintenance cost is low.The seam crossing of cement concrete pavement is the weak spot on road surface, as dealt with improperly, in use there will be disconnected plate, the problems such as Subgrade Subsidence.
The main cause that the problems referred to above produce is that road surface water infiltrates roadbed by seam, if roadbed and ubbase drain bad, for a long time by water soaking, destabilization of roadbed or strength deficiency will be caused, in addition the repeated action of vehicular load, and make road surface produce irregular fracture.
The fracture of road slab and cracking can have a strong impact on surface evenness, cause road damage, thus affect vehicle traveling, even cause serious traffic accident.
Therefore, how designing a kind of brand-new device, can use in the process of deployment of rigid pavement, to solve the various problems that surface drainage does not freely cause, is that those skilled in the art need solution badly.
Summary of the invention
The object of the invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of cement concrete roadbed protective pad plate and technique are provided.Protection backing plate provided by the present invention, can in the process of deployment of rigid pavement guiding concrete parting direction, and can draining smoothly; Present invention also offers the construction technology of this protection backing plate of application.
In order to reach above-mentioned purpose, the present invention adopts following technical scheme:
A kind of cement concrete roadbed protective pad plate, comprise protection backing plate body, this protection backing plate body upper surface is provided with many partings, and be provided with the drain groove corresponding with described parting in protection backing plate body, parting is connected with described drain groove.
Preferably, the sectional area of described drain groove is greater than the sectional area of parting.
Preferably, arbitrary parting all be arranged in parallel with adjacent parting.
Preferably, the cross section of described drain groove is hexagon, circle or rectangle.
Present invention also offers the construction technology applying above-mentioned protection backing plate, comprise the steps:
A. protection backing plate body is faced up, keep flat, be embedded in the bottom of concrete joint-cutting in advance;
B. concreting is carried out according to construction technology;
C. the concrete after building is cut;
D. after concrete coagulation or temperature reduce, the automatic parting of concrete.
Preferably, in described step C, depth of cut is 1/3rd of concrete thickness.
Preferably, in described step C, cutting position is the top of parting.
The invention has the beneficial effects as follows: by the autonomous parting of joint-cutting guiding concrete after rigid pavement has been laid, make joint-cutting extend to protection backing plate, then rainwater will flow to protection backing plate by the joint-cutting along rigid pavement, derives through drain groove,
And then effectively ensure that the application life of rigid pavement.
Accompanying drawing illustrates:
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the sectional drawing of protection backing plate;
Fig. 2 is the part sectioned view of protection backing plate;
Fig. 3 is the plan view of protection backing plate;
In figure: 1, protect backing plate main body, 2, parting, 3, drain groove.
Detailed description of the invention:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1: a kind of cement concrete roadbed protective pad plate, its structure as Figure 1-3, comprise protection backing plate body 1, protection backing plate body 1 upper surface is provided with many partings 2, be provided with the drain groove 3 corresponding with described parting 2 in protection backing plate body 1, arbitrary parting 2 is all communicated with corresponding drain groove 3.
The sectional area of drain groove 3 is greater than the sectional area of parting 2.
Arbitrary parting 2 all be arranged in parallel with adjacent parting 2.
According to construction needs, hexagon, circle or rectangle can be selected in the cross section of drain groove 3.
Present invention also offers the construction technology applying above-mentioned protection backing plate, comprise the steps:
A. protection backing plate body 1 is faced up, keep flat, be embedded in the bottom of concrete joint-cutting in advance;
B. concreting is carried out according to construction technology;
C. the concrete after building is cut;
D. after concrete coagulation or temperature reduce, the automatic parting of concrete.
Wherein, in described step C, depth of cut is 1/3rd of concrete thickness; And cutting position is the top of the parting 2 on protection backing plate body 1.
Principle of the present invention is: the width of parting 2 is less, during concreting, cement paste can not enter parting 2, rigid pavement reaches through artificial joint-cutting after intensity, shrinkage cracking, then joint-cutting extends to above backing plate automatically, when there is ponding on road surface, ponding will flow to protection backing plate parting from parting, flows in drain groove 3, then derives through drain groove 3.
According to requirement of engineering, protection backing plate body can stretch out 50-80mm in edge, road, plays better drainage.
After have employed said structure, the draining backing plate that this programme provides, can avoid the damaged or destroyed by flood of seam crossing roadbed, improve the useful life longevity of cement concrete road.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
