Cement road surface easy to appear the number can be used to protect a concrete solution

Protection of concrete, solve the problem of cement pavement concrete repairing concrete pavement on no. 1 sand to protect the concrete repairing concrete crack number one as we know, cement road surface has a large bearing capacity, good stability, long service life and daily maintenance the advantages of low cost, so, in our daily life, the cement pavement is very common. Due to some special reasons, the cement pavement is easy to appear some problems, to cause the pedestrians and vehicles must be confused. According to the new material co. , LTD. , years of construction case summary, problems in cement pavement basically has the following four categories, can be used to protect a concrete solution. The first kind of cement pavement crack, the cement pavement breakage type of this kind of problem is mainly caused by through the thickness of the fracture cracks of concrete surface, under the action of these cracks, concrete pavement is split a piece, undermines the integrity of structures on the surface. The specific construction form of panel broken there are mainly four categories, respectively transverse crack, longitudinal crack, cross crack and fracture voids. The second type of this kind of problem is mainly composed of cement pavement deformation on the surface of the cement road surface plate, which is caused by the vertical displacement of a big while the integrity of the surface plate is not destroyed, but can also bring comfort to the pedestrians and vehicles. The deformation of the concrete manifestation is wrong, the layer stuck and arch, etc. The third type of cement pavement joint damage type of this kind of problem is mainly by the transverse or longitudinal seam in cement pavement joint sealant, which is caused by the loss or failure of such as plate seam joint sealant spalling. The fourth type of cement road surface damage type of this kind of problem is mainly caused by structural damage, refers to the local damage occur in the surface of the cement pavement. The specific construction form of surface damage is explicit, holes, etc. According to the analysis of current problems teng jia luqiao sums up the main reason of this phenomenon has the following five: first, the prevention and control of water is not enough, poor subgrade soil and subgrade high underground water level; Second, the roadbed uneven settlement; Third, the pavement base, surface strength is insufficient; Fourth, the road there are often overweight load phenomenon; Fifth, in the design and construction has certain defects. To solve these problems well, must start from the cement road surfaces in daily maintenance. Management in completes the road sweeping cleaning, surface joint maintenance at the same time, also shoulder, sorting capacity road repair regularly, and often clean ditches, eliminate seeper, eliminate the hidden trouble of the pavement. If it found problems in cement pavement is irreversible, should organize relevant professionals, the existing pavement maintenance and maintenance. Based on the experience of building technology co. , LTD. , pavement maintenance can be divided into fracture repair, broken horn repair, chew and repair, such as hole repairing concrete way of repair, should analysis and construction in different situations. Concrete repair methods to the website of the teng jia bridge has to consult, hope every day we can walk on the flat, patency of the cement road surfaces to protect highway, everybody is responsible for.
