In May 2003, Cao 'an Village was abolished and Xin 'an Community was established. Cancel Xindong Village and establish Hengcao Community; Cancel Xinpu Village and establish Xugongqiao Community. Cao An Street was established in June, which governs Xin 'an Community, Hengcao Community and Xugongqiao Community. After the establishment of Overseas Chinese Economic Development Zone in 2006, the streets of Cao An naturally disappeared.
In June 2006, Huaxi Community and Huaan Community were established. At this time, huaqiao town has jurisdiction over 6 communities including Xin 'an, Hengcao, Xugongqiao, Huaxi, Hua 'an and Huaqiao, 18 administrative villages and 139 natural villages, namely Shang 'an, Tokyo, Jincheng, Jishan, Yang Shun, Gunan, Pengshan, Tianfu, Xinhu and Xingbang.
In February, 2007, Huaqiao Street and Cao An Street were established, and the sub-district offices were dispatched by the Administrative Committee of Overseas Chinese Economic Development Zone, with a deputy-level organizational system. Huaqiao Street governs Huaxi Community, Huaan Community and Huaqiao Community, while Cao An Street governs Xin 'an Community, Hengcao Community and Xugongqiao Community. Huaqiao town is the Jiangnan ancient land belt in the East China platform. In ancient times, influenced by the resurgence of Huangpu River, sediment gradually deposited. The soil parent material is river and lake sediments, and some areas are covered with Quaternary loose sediments within 7-140m underground. The land-forming age was about 5000-6000 years ago.
Huaqiao town is the most developed area of soft soil in Kunshan City, with muddy silty clay and muddy clay as the main soil layers, and Quaternary Holocene alluvial and lacustrine deposits as the main ones. The stratum distribution from top to bottom is mainly filled soil, silty clay, silty clay mixed with silty soil, silty clay, sandy soil, silty clay and other interlayers. The general characteristics of soft soil are shallow burial, relatively new sedimentary age, large void ratio and natural water content, high compressibility, weak water permeability, low shear strength, high sensitivity and thixotropy, which are easy to cause ground deformation disasters under the condition of increasing ground load. General situation of stratum distribution in huaqiao town: The average thickness of the fill is about 2.2m, which is mainly cohesive soil mixed with soft soil. Silty clay is mixed with plant roots and a small amount of rubble brick chips, with an average thickness of about1.8m, iron oxide spots, blue-gray stripes, slight luster, no shaking reaction, medium dry strength and medium toughness. Silty silty clay contains a small amount of humus and organic matter, with a slight luster, no shaking response and medium dry strength. It is the main bad engineering geological layer with great thickness variation, which has great influence on the development of underground space. Silty clay and silty soil are interbedded, with horizontal bedding developed, with "Melaleuca cake" bedding, occasional shell fragments, slightly shiny, slow vibration response, medium low dry strength and medium low toughness. Silty clay is relatively homogeneous, with a small amount of silt in the upper part, no bedding development, and a thin layer of silt and silt at the bottom. Sandy soil, slightly shiny, with no shaking response, medium dry strength and medium toughness, mainly composed of timely and feldspar, containing mica flakes and a small amount of silty clay thin layers, all saturated, with a thickness of 2-36.4m and a buried depth of-58-92m. There is no sandy soil layer in some areas, and silty clay is mixed with a small amount of silt and thin silt, which is slightly shiny, has no shaking response, and has medium dry strength and toughness.
Huaqiao town is a water town in the south of the Yangtze River, with rivers and lakes. During 1994, the situation of rivers, bangs, ponds and ponds in China is as follows: the main transit rivers are Wusong River, Jimingtang, Gupu, Xisijing, Qiujiang, Xugong River, Caotang River, Majing River, Dawapu, Xuejiajing, Hengtang River and Pan Zhengpu. There are 0/3 rivers in China, including Hanjing River, Palm Tree Hill, Zhou Pu, Qianhejing, Maoxianghe River, Zhichangtang, Qian Jing, Luxiangjing, Xinzhuang River, Xia Quan Jing, Luojiajiang, Xiewangjing and Sanlingjiang River, with a total length of 30.56 kilometers. There are 282 village-level water systems, including rivers, lakes, ponds and ponds, with a total length of 293.28 kilometers. 1995 by the end of 2006, with the acceleration of urbanization and industrialization, a large number of rivers were filled and the water system ecology changed. The Jimingtang and Dawapu crossing the river are filled with Yangshun Village 1.8km for road construction, and the rest are unchanged; Among the rivers in China, Xiewang Well in Pengshan Village has been filled with 1.2km, Xiaquan Well has been filled with about 1km, Luojiajiang has been filled with 2.5 km, and the rest have not changed. There are153 (159.12km) rivers, weirs, ditches, ponds and ponds at the village level, and the rest129 (134.16km). Among them, tunnel, mountain bank, Jincheng, Xinhu and Tianfu Village 10 1 article, with a total length of 105.04 km, and the remaining river course is 80% due to road construction and greening filling 19 (19.76 km). Five villages in Gunan, Yang Shun, Pengshan, Xingbang and Jishan, five communities in Hua 'an, Huaxi, Hengcao, Xugongqiao and Xin 'an, 18 1 original river bank, full length 188. 24 kilometers, 134 (65438+)
underground water
Shallow groundwater in huaqiao town mainly includes pore water and micro confined water. Pore phreatic water mainly exists in shallow clayey soil, with poor water yield, and ground evaporation is the main drainage method; The underground water level is stable, generally between 0.25 and 0.54 m, and its corresponding elevation is generally between1.00-1.41m, with an average of1.71m. Micro confined water mainly exists in interlayer sandy silt, and the main recharge sources are vertical infiltration of shallow groundwater and lateral runoff of groundwater, with lateral runoff of groundwater as the main discharge mode; The buried depth of aquifer is generally between 3.0-11.0m. ..
