毛竹的直径为Ф50-100mm。The diameter of moso bamboo is Ф50-100mm.
毛竹的底部位于桩体底部上方1-2m。The bottom of the moso bamboo is located 1-2m above the bottom of the pile body.
本实用新型的施工原理：Construction principle of the utility model:
每根水泥土搅拌桩施工完毕，随即进行插设毛竹的施工，毛竹的直径在50mm～100mm之间，根据水泥土搅拌桩直径来选择。毛竹必须在搅拌桩水泥土硬化前插入。选用的毛竹必须通直光滑，先采用人工往桩中心压入一部分毛竹，再利用桩机将毛竹剩余部分全部压入水泥土中，压的时候应注意将毛竹粗段朝上，细段朝下。加筋水泥搅拌桩施工完毕，挖除桩头松散破碎的部分，露出20cm～30cm毛竹头，沿桩顶将毛竹头用钢筋网连接，并用C20混凝土浇筑成镇口板，毛竹必须在搅拌桩机钻杆提出后立即插入，以保证在水泥土未凝结之前完成。After the construction of each cement-soil mixing pile, the construction of moso bamboo is inserted immediately. The diameter of the moso bamboo is between 50mm and 100mm, which is selected according to the diameter of the cement-soil mixing pile. Moso bamboo must be inserted before the cement soil of the mixing pile hardens. The selected moso bamboo must be straight and smooth. First, manually press a part of the moso bamboo into the center of the pile, and then use the pile driver to press all the moso bamboo into the cement soil. When pressing, the thick section of the moso bamboo should be facing upwards, and the thin section should be facing down. . After the construction of the reinforced cement mixing pile is completed, the loose and broken part of the pile head is excavated to expose the 20cm~30cm moso bamboo head. Insert the drill pipe immediately after it is raised to ensure that it is completed before the cement soil is set.
本实用新型的有益效果：The beneficial effects of the utility model:
在水泥土搅拌桩中插入毛竹，形成竹筋水泥土搅拌桩，既可以承受一定的竖向承载力，又可以承受横向剪力。可以广泛地应用于基坑工程的围护结构，盾构进出洞端头的土体加固，以及地基处理工程中。具有易挖除性、经济性、临时性。Moso bamboo is inserted into the cement-soil mixing pile to form a bamboo-reinforced cement-soil mixing pile, which can not only bear a certain vertical bearing capacity, but also bear horizontal shear force. It can be widely used in the enclosure structure of the foundation pit project, the soil reinforcement at the end of the shield tunnel entry and exit, and the foundation treatment project. It is easy to dig out, economical and temporary.
