Vacuum preloading foundation treatment clay sealing wall construction method
The invention discloses a construction method of a clay sealing wall for vacuum preloading foundation treatment, and belongs to the field of building construction.The construction method of the clay sealing wall for vacuum preloading foundation treatment comprises the steps that pile testing is conducted, and the slurry mixing proportion, the guniting length, the guniting amount and the guniting pressure are determined; the method comprises the following steps: setting out a mileage center position of a reinforced road section by paying off, inserting bamboo sheet piles into a soil layer, marking numbers on the bamboo sheet piles, pulping in a pulping pool, taking clay as a mixing material, and mixing the clay into a soil body of the mixing pile to prepare slurry; slurry prepared in the slurrying pool is communicated with a grouting head of a deep stirring machine through a slurry pump and a slurry conveying pipe, a stirring pile drill of the deep stirring machine sinks and stirs, meanwhile, the grouting head sprays slurry, the diameter of a clay stirring pile is smaller than the distance between the circle centers of every two adjacent clay stirring piles, every two adjacent clay stirring piles are meshed with each other, and the clay stirring piles are arranged in the deep stirring machine. The multiple clay stirring piles are meshed with one another to form a clay sealing wall.
本发明公开了一种真空预压地基处理粘土密封墙施工方法，属于建筑施工领域，本真空预压地基处理粘土密封墙施工方法包括：进行试桩，确定泥浆配合比、喷浆长度、喷浆量和喷浆压力；通过放线定出加固路段的里程中心位置，用竹片桩插入土层并在竹片桩上标记编号，在制浆池中进行制浆，采用粘土作为拌和材料，将粘土掺入搅拌桩土体中，制得泥浆；将在制浆池中制备的泥浆通过浆泵和输浆管与深层搅拌机的注浆头连通，深层搅拌机的搅拌桩钻下沉搅拌，同时注浆头进行喷浆，粘土搅拌桩的直径小于相邻的两个相邻的粘土搅拌桩圆心之间的距离，使相邻的两个粘土搅拌桩相互咬合，若干粘土搅拌桩互相咬合形成粘土密封墙。
