 After the construction of housing caused by uneven settlement of the first housing construction procedures and methods for detecting damage 
 Detection of cracks in the wall first built housing happen, you can find the following characteristics: I. Emerging range: most of the joint distribution ④ ~ ⑤ axis, the crack is longer, larger, and the width of larger; ① ~ ③ axis minor cracks appear, crack width smaller. Figure 5 wangzhai vertical and horizontal cracks in the wall housing the general situation there appears inclined wall built after the point in the direction of the diagonal crack houses, and appear in the window corner or building (housing) is connected to the wall surface structure and level of development of cracks at , the maximum crack width of 5mm. Part of the junction of vertical and horizontal wall cracks appeared vertical development. 2.3.2 Detection through floor cracks detected, the first building houses three floors, roof ④ floor hallway near the axis there are 45. Diagonal cracks developed, shown in Figure 6. () 666 () 663 floors schematic diagram of the roof structure diagram of Figure 6 wangzhai floor cracks Ⅱ. Longitudinal cracks in the wall has the following characteristics: a horizontal direction vertical wall cracks, structural columns and walls along the junction and along the vertical development of diagonal cracks in the newly built house on the point side of the inclined cracks. The development of both horizontal cracks appear in the building (housing) is connected with the wall surface structure or the staircase at the plate and connected at the wall,Beats By Dre Studio, the maximum crack width of 12mm. Ⅲ. Transverse cracks in the wall has the following features: cross-0-0-O2.3.3 build houses first floor, ground tilt test build houses on the site of the first floor, tilted towards the ground measurements, the test results shown in Figure 7. Can be seen from Figure 7,vibram five fingers outlet, the first building housing ⑤ ~ ⑥ axis in floor (ground) surface significantly to the west side of the tilt, height difference of about 20 ~ 3Omm. According to another construction site on the first floor plan house roof by = - Mission Figure 7 wangzhai layer plane, take a photo diagram of the ground tilt measurements showed that the west side of the first houses built was inclined roof. 2.4 The foundation excavation inspection the actual situation according to the site, select the first building housing inspectors ⑥ ⑩ shaft axis and the outer corner of the intersection and ⑤ ⑧ shaft axis and intersecting the corner to dig two test results described. A drought. Cans. Li i Figure 1 Figure 8, the first construction of a housing and build houses after the excavation of test Figure 8. Seen by the figure,Beats By Dre Headphones, (1) the basis of the first building housing ⑥ axis depth of about 2050mm, ⑨ shaft foundation depth of about 22l0min, the base width of about 5lOmm,tods shoes outlet, ± 0. O0 the following features 400mm high reinforced concrete ring beam; (2) after the construction of building foundation building foundation building depth than the first depth, a broad shift to shake the city. Since the construction site limits body size measurements can not be dug in the basement; (3) after the foundation and the adjacent building housing the basis of the first houses built in close connection, or even part of the cast into a whole; (4) sandy beach soil were soil around housing on the basis of all fall to the soil. 3. Analysis of test results for housing based on the first crack distribution, shape location, size and orientation, and degree of correlation detection floor level, comprehensive analysis of the following views: (1) According to the Chinese National Standards ((building foundation design ( GB50007-2002) Section 5.1.5 of maintain a certain distance. Its value should be based on the size of the original building loads, foundation and soil conditions determine the form. When not meet the above requirements should be taken when sub-construction, temporary reinforcement support, sheet piling, diaphragm wall construction measures such as or strengthening the existing building foundation deeper depth of building foundation, part of the foundation and even before pouring into the building housing the basis of a whole, because the soil is sandy beach soil, in the upper part of the building loads there is a certain deformation. It is understood that after the construction of building foundation construction of appropriate construction measures are not taken, leading to construction of building foundation created after the settlement drive was built adjacent to the first settlement houses have become the basis of a balanced ⑧ axis to produce additional settlement, causing build houses first appeared uneven settlement cracks in the wall , floor, ground tilting and cracking and other undesirable phenomena. (2) first built more housing transverse wall hole, l base layer part of the wall is not located directly on the concrete floor, masonry, built the first house by the foundation wall uneven the main reason for cracks; the same time,herve leger toronto, the first structure built housing arrangement is not reasonable in itself, by the uneven settlement of foundation and temperature changes, the effects of concrete shrinkage cracks easily.
