Construction method of cast-in-place bent cap located in wetland
The invention relates to a construction method of a cast-in-place bent cap in a wetland, which comprises the following steps of: investigating the natural landform condition of the location of each group of pier columns serving as a cast-in-place bent cap foundation in the wetland on site, classifying the pier columns into pier columns in muddy ground and pier columns in water; a cushion layer, a partial pressure I-shaped steel frame, a cement layer and plastic cloth or plastic floor leather are laid on the muddy ground on the periphery of the bridge pier column, wherein the periphery of the lower end of a projection line of the cover beam extends outwards by 1 m, so that a cover beam bottom formwork is formed; a bottom floating layer, a pressure equalizing plate and a gravel pressure equalizing layer are sequentially laid on the bottom ground in a steel cofferdam cylinder from bottom to top in the construction of a pier column cast-in-place bent cap in water. According to the construction method, the cast-in-situ cover beam in the wetland can be constructed under the condition that the wetland environment is not occupied and damaged in a wetland park, secondary land acquisition is saved, damage to the wetland environment caused by secondary excavation of a foundation pit is avoided, labor and time are saved, and the construction efficiency is improved.
本发明涉及一种位于湿地内现浇盖梁的施工方法，包括如下步骤，现场勘察湿地内作为现浇盖梁基础的每组桥墩柱所在地的自然地貌状况，归为处在泥泞地的桥墩柱和水中桥墩柱，对处在泥泞地桥墩柱的现浇盖梁施工采用在盖梁投影线下端周边外扩1m的桥墩柱周边泥泞地面上铺设垫层、分压工字钢架及水泥层、塑料布或塑料地板革形成盖梁底模板；对处在水中的桥墩柱现浇盖梁施工采用在钢围堰筒内底地面上，从下至上依次铺设底浮层、均压板和砂石均压层。本发明可以在湿地公园内不对湿地环境进行侵占和破坏的情况下，对湿地内现浇盖梁的施工，节约了二次征地，避免基坑二次开挖对湿地环境的破坏，省工省力、提高施工功效。
