Help rural rejuvenation, investigate Dongkou County, "Doctoral Practice Group" of Changsha University of Science and Technology

(Correspondent Li Xiaojun Cheng Xiaokang) Recently, under the leadership of the instructive teacher Li Xiaojun, the Ph.D. of the School of Civil Engineering of the School of Civil Engineering of Changsha University of Science and Technology went deep into Chefa Village, Dongkou County, Shaoyang to carry out summer professional practice. The cadres of the "two committees" of Che Tian Village received the practice group, and introduced the basic situation of Che Tiancun to the practice group and the actual needs of the current Ping An rural construction. Based on the actual needs of the village, this summer practice mainly focuses on the professional testing and research work of "self -built house inspection, bridge safety, and slope cut slope".

The "physical examination" house puts forward personalized "repair" suggestions

Chetian Village is located on the banks of the Zhenpingxi River. The terrain is mainly hilly. In order to find out the bottom of the family and accurately grasp the scope and object of the detection, the doctoral practice team led the village to the village to find the households to understand the distribution and use of the houses of Che Tiancun. "Is there any water seepage in the house? Are there any cracks in the wall? Is there a reinforced reinforcement reinforcement in the reconstruction area?" It is both an important information about the safety of houses and an important basis for the test of doctoral practice group. According to inquiries and investigation, the practice group listed 30 brick houses in Che Tian Village as the key testing objects, and through professional instruments such as the full station, the level instrument, the rebound instrument, the floor of the floor, Professional testing and evaluation of the overall tilt, deformation and settlement. At the same time, the doctoral practice group put forward personalized "repair" suggestions on dangerous houses, so that the villagers live safer and assured. In the future, the doctoral service group will comprehensively summarize the common problems of the safety of self -built houses, form a survey report, and provide suggestions for the construction of Ping An rural construction.

The "consultation" slope proposes ecological protection solutions

The practical group surveyed the slope of 4 located on both sides of the rural highway or the foot of the mountain slope and the hidden hidden dangers. It was found that some slopes had obvious collapse and slippery phenomenon. Essence By conducting a comprehensive survey of the house foundation and slope, the practical group records the slope -cut environment and typical landslides in detail, and uses 10 sets of land samples to obtain soil parameters for stability analysis. According to the actual situation of the slope, the members of the practical group intend to take the protection of plant protection or slope -cutting technology with low cost and low cost, and remind villagers to pay attention to the smooth flow of the slope drainage. Do not block it.

In addition, the Practice Group learned that Che Tian Village actively responded to the "rural revitalization" development strategy. Through the rural assistance plan, villagers living in high -risk areas were transferred to low -risk areas. The phenomenon of landslides and the loss of security and economic losses caused by strengthening the stability of the slope improved the overall living environment.

"Pulse" bridge, intelligent maintenance of rural revitalization bridge

The bridge in Che Tian Village has been completed, low in design standards, and low maintenance time, which has laid hidden safety hazards for rural passage. The practice group has detected five stone arch bridges with serious damage.

Among them, the bamboo city bridge is a link between the village and the town. The volume of the bridge deck is large, the vessels under the bridge are frequent, and the structural performance of the bridge has been affected to some extent. After the doctoral practice group initially understood the structure and traffic of the bamboo city bridge and the stone arch bridge, it measured the details of the bridge length and bridge width in detail. At the same time, the elevation and height of the Bridge Bridge Bridge by the whole station were measured. In accordance with the requirements of the "Highway Bridge Candidate Specification (JTG5120-2021), a comprehensive and detailed inspection of important parts. "The bridge pavement layer is loosened due to the lack of maintenance, and the traces of the flushing of the bridge by the water flow are also obvious." The team member Yan Wanli said based on the measurement results of the stone arch bridge.

Considering the needs of villagers, the PhD Practice Group proposed the reinforcement plan for assembly block arch bridges. This reinforcement method is easy to construct and beautiful shapes, which provides a guarantee for the convenience and living convenience of Che Tiancun.
