Research Rectification And Reinforcement Technology Of Brick-concrete Structure

Brick-concrete structure drawn as easy, simple construction and low cost are welcomed by people, especially suitable for the construction of mountains and small towns, and urban redevelopment. However, since the major brick-concrete structure, shear strength is low, poor seismic performance, and based largely on natural foundation, prone to differential settlement, tilting, cracking and other issues. For the structural features and foundation characteristics of brick-concrete structure,Analysis of housing situation, all components of security, proposed for a variety of brick-concrete structure Rectification and reinforcement method.In this paper, a new building after the main cap differential settlement, tilting, cracking and other problems,after testing in the identification of the building structure, foundation,analysis of the building of uneven settlement, tilt, and crack the problem. For new buildings did not complete the consolidation settlement of foundation soil characteristics,make use of pit-static pile method of reinforcing the southern end of gailou large settlement site, and not static pile unloading preloading underpinning pile closure, so that the role of pile and foundation soil to prevent the continued subsidence of the site. In the pile under the top lift, so that the basis of settlement houses to be terminated, and a slight lift. For the northern part of the small settlement depend on the building of weight, use of housing is not the basis of depth and rigidity characteristics,using the shallow deviation rectification technology. Cutting through the shallow area of soil to reduce soil support, increased shallow soil in the additional stress of the method to force the basis of the settlement. When the basis for settlement to the target request, it works with the already completed underpinning pile underpinning,construction of cutting and digging in holes and dig soil pits to dust compacted backfill. This method is simple, cost-reasonable,brick-concrete structure in house defletion-corration reinforcement project and good results have been achieved.Deviation in reinforcing project building subsidence and tilt rate changes of measured data, the building after rectifying similar to reinforce has reference value and guidance.
