Water-stopping cement gum material and water stopping method for lock catch of lock catch steel pipe pile cofferdam
The invention provides a water-stopping cement gum material and water stopping method for a lock catch of a lock catch steel pipe pile cofferdam, and belongs to the field of cofferdam construction. The water-stopping cement gum material is formed by mixing clay, bentonite, polypropylene fibers and water. The water stopping method comprises the following steps of: preparing the water-stopping cement gum material; filling a slotted steel pipe with the water-stopping cement gum material, and enabling a lock catch insert to enter the slotted steel pipe in a vibration inserting and beating manner;and compacting the water-stopping cement gum material. According to the water-stopping cement gum material and the water stopping method for a lock catch of a lock catch steel pipe pile cofferdam, which are provided by the invention, the limitation of the condition that there is no good natural clay around a project is avoided, the surrounding clay is selected, bentonite and polypropylene fibers are added to improve the surrounding clay into soft plastic cement gum with good performance, cohesive force and water dispersing performance of the lock catch steel pipe pile cofferdam are improved, and the success rate of water sealing of the lock catch steel pipe pile cofferdam is guaranteed. The raw materials of the water-stopping cement gum are easy to purchase and low in price, and the water-stopping cement gum has good economic benefits.
本发明提供了一种用于锁扣钢管桩围堰锁扣的止水胶泥材料及止水方法，属于围堰施工领域，止水胶泥材料由粘土、膨润土、聚丙烯纤维添加水混合而成。止水方法包括步骤配置所述止水胶泥材料；向所述开缝钢管中填充所述止水胶泥材料所述锁扣插件采用振动插打的方式进入所述开缝钢管；压实所述止水胶泥材料。通过本发明提供的用于锁扣钢管桩围堰锁扣的止水胶泥材料及止水方法，可不受工程周边无良好的天然粘土限制，选取周边粘土，通过添加膨润土和聚丙烯纤维改良成性能良好的软塑状胶泥，使其粘聚力和遇水离散性能改善，确保锁扣钢管桩围堰封水成功率。该止水胶泥各原材料易于购买，且价格不高，具有较好的经济效益。
