Construction method of underground wall capable of blocking muddy water
The invention relates to the technical field of building construction, in particular to a construction method of an underground wall capable of blocking muddy water, a prefabricated underground wall is arranged in front of a reserved hole of an open caisson, and the underground wall is filled with high-plasticity clay; fine aggregate concrete with a water stopping effect is poured around the underground wall; a counterweight load is arranged above the high-plasticity clay; when the jacking pipe penetrates through the underground wall, the high-plasticity clay is tightly attached to a pipeline of the jacking pipe under the action of the balance weight to form a mud film. The method has the advantages that the soil body is replaced within a small range, after a jacking pipe penetrates through the underground wall, under the action of the balance weight, a jacking pipe pipeline is tightly attached to high-plasticity clay, a mud film is formed, water and soil outside a reinforced area can be prevented from flowing into a well, and therefore the risks of water gushing and sand gushing are avoided; and the construction investment cost is low, and the risks of water gushing and sand gushing are avoided.
本发明涉及建筑施工技术领域，尤其是一种可阻隔泥水的地下墙的施工方法，在所述沉井的预留洞口前方打设一副预制的地下墙，所述地下墙内部填充高塑性黏土；在所述地下墙的四周灌注有止水效果的细石混凝土；在所述高塑性黏土的上方布置配重加载；当顶管穿越所述地下墙时，所述高塑性黏土在所述配重的作用下与所述顶管的管道紧密贴合形成泥膜。本发明的优点是：小范围内将土体置换，当顶管穿越此幅地下墙后，在配重的作用下，顶管管道与高塑性黏土紧密贴合，并形成泥膜，可阻止加固区外的水土流进井内，从而避免发生涌水、涌沙的风险；施工投资成本较小，避免发生涌水、涌沙的风险。
