Leaking stoppage method of deep foundation pit support structure
The invention relates to a plugging method for a deep foundation pit support structure, which is used for plugging holes formed in the support structure and a ground layer outside a foundation pit due to leakage, and comprises the following steps: providing dry kelp, filling the hole opening of the holes with the dry kelp, and plugging the hole opening of the holes by utilizing the dry kelp to absorb water and expand; and providing a grouting material, and injecting the grouting material into the hole to fill the hole. According to the method, the hole openings of the holes are filled with the dried kelp, water in the holes is absorbed by the dried kelp, the size of the dried kelp can be expanded by about three times, accordingly, the hole openings of the holes can be tightly blocked, meanwhile, gaps between the dried kelp can be filled, overflow of grouting materials in the grouting process can be greatly reduced, the consumption of the grouting materials is reduced, and the grouting efficiency is improved. The construction cost is reduced.
本发明涉及一种深基坑围护结构的堵漏方法，用于封堵因渗漏而形成于围护结构和基坑外部地层上的孔洞，堵漏方法包括如下步骤：提供干海带，将干海带填塞于孔洞的洞口处，利用干海带吸水膨胀以封堵孔洞的洞口；提供注浆材料，将注浆材料注入孔洞内以填充孔洞。本发明中利用干海带填塞孔洞的洞口，孔洞内的水被干海带吸收，使得干海带的体积可膨胀3倍左右，从而能够紧密地封堵住孔洞的洞口，同时能够填塞住干海带间的缝隙，可以大大减小注浆过程中注浆材料的外溢，减小注浆材料的消耗量，降低施工成本。
