Cellular concrete reason Prevention (BC-type concrete pavement repair material) formed Pock 2.1 Honeycomb Prevention carefully designed cement concrete pavement crack treatment, strict control of BC cement mixing ratio, always check done accurate measurement. About concrete rendered disease prevention and control shall be done in the normal maintenance work, we should insist on "prevention, prevention of contact" criteria, tailored to work. Early prevention approach has four aspects: (1) the cement concrete road just rendered disease slight division can only pump sludge or small cracks cement pavement crack how to deal with, if left unchecked, will gradually dispersed pavement cracks and eventually form a large area of ??severe fragmentation. So, do a good job of pre-cement concrete pavement preventive maintenance is very crucial, we must do the ground survey, early detection, and timely prevention. (2) to pay special attention to the prevention and treatment of surface water, and adhere to the "sparse mainly sparse block contact" criteria. That work together to do the pouring of surface water to boot, for often the road to the addition of water and drainage ditches sink drain, quickly remove water. Cement pavement cracks that can bridge strong family Henan Department of Science and Technology Co., Ltd. is a professional concrete road / bridge repair production of new materials and a full range of solutions and services integrator tactic scheme cement pavement crack processing method is rapid access road repair industry leader! L 1.1 crack crack crack free surface of the concrete pavement refers mesh, shallow and fine hairline cracks, was a small hexagonal tread depth of 5 -l0mm. 1.2 transverse cracks, longitudinal cracks, diagonal cracks and intersecting cracks transverse cracks, longitudinal cracks, diagonal cracks refers to a fracture along the road approximately perpendicular to the center line, parallel to the direction of bias generated by these types of cracks in the road and often temperature effect gradually expanded, and ultimately through the thickness, through the board, divided into two or three pieces of concrete slabs; cross fracture refers to a fracture intersecting the plate is divided into three or more (also known as broken boards). Cause 2 cracks concrete slab cracks reasons are many, after the actual investigation combined with our experience, the main reason is as follows: 2.1 soil base effect (1> land-based filler messy, less than 93% degree of compaction, uneven settlement resulting in cracks roadbed sedimentation occurs in two situations: First, weak foundation, not good reinforcement, its carrying capacity is lower than covering on top of it fill soil gravity compression; the second is filling lamination. Real bad, density lower than the design requirements, the inevitable lack of strength, it will deform under its own weight and external force. compactness of the smaller, the greater the deformation. (2) embankment high water table, poor geological conditions, ground weakness, low intensity, deformation under heavy traffic load effect is too large, resulting in Concrete Rupture how concrete pavement crack treatment, pavement cracks, the Department can bridge can be provided by the Department of Road and Bridge Technology Co., Ltd. Henan Henan Bridge Technology Net Power Ltd. (www.hnlq88.com) strong, credible, in Zhengzhou, Henan chemical products industry has accumulated a large number of loyal customers. The company better work attitude and continuously improve innovative ideas will be able to lead the Department of Road and Bridge and you hand in step the brilliant, for a better future!
