Description
Technical field
The present invention relates to highway construction technology field, relate in particular to a kind of semi-rigid type base interlayer cement slurry sprinkling with
Base paves synchronous construction method.
Background technique
Main supporting course of the semi-rigid type base as flexible pavement in highway, is typically designed thickness all between 30-40cm,
Due to being limited by construction equipment, construction technology and raw material, in conjunction with associated specifications requirement, usually all divides two layers and spread out twice
Paving construction.In order to improve the layers cementing effect of semi-rigid type base, guarantee the global consistency of its stress, design and code requirement
Using cement slurry as two interlayer bonding agents, for this regulation, following three kinds of schemes are mainly used in construction at present: first is that
Artificial sprinkling；Second is that (semi-automatic) the sprinkling construction of human assistance simple machine；Third is that using dedicated full automatic cement paste
Distribution vehicle spraying operation (full-automatic).
The construction technology of artificial sprinkling and semi-automatic construction is simple, but recruitment quantity is big, construction quality is unstable, construction
Progress is slow, construction cost is high, and operability is difficult, and is not suitable for extensive tis-sue construction.Dedicated full automatic cement paste is spilt
Cloth vehicle spraying operation although solve the problems, such as recruitment quantity greatly and construction quality stability, but due to its process flow be elder generation
Spray cement slurry, after pave semi-rigid type base, so still having the disadvantage that
1, the sprinkling of cement slurry is all preparatory spread on the sub-layer for paving section, the cement slurry appearance when progress upper layer paves and constructs
Easily destroyed by the u-turn reversing of the advance of paver, transport vehicle and operating personnel in walking of workspace etc..
2, in the operation process for paving base, the cement largely sprayed in advance can starch the traveling crawler for being adhered to paver
On transport vehicle tire, causes cement slurry uneven and after the cement slurry of excalation or even large area taken away by wheel, influence
On the bond effect gone to a grassroots level, can also pollute surrounding enviroment.
3, cement slurry first sprays, and paves after base, especially in the pavement construction operation process of large area, if meeting high temperature
Weather or construction equipment failure problem, in the case that the progress that paves lags, the cement slurry sprayed in advance can be dried or wind
It does into concrete grey and loses adhesive property.
If 4, being constructed in rainy season, rain suddenly in work progress, the cement slurry first sprayed can be washed away or be rushed accumulation, water by rainwater
The effect of interlaminar bonding is just not achieved in mud, and accumulation body can also leave hidden danger of quality.
5, process flow is all first to spray cement slurry, after pave semi-rigid type base two procedures, when having one in process
Between it is poor, there are the hidden danger of quality, progress and secure context on procedure connection.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and provide it is a kind of can improve construction quality, reduce construction cost,
