Intelligent grouting construction method and intelligent grouting construction equipment for building raft foundation
The invention particularly discloses an intelligent grouting construction method and construction equipment for a building raft foundation. The construction method comprises the steps that a grouting pipe penetrates through a to-be-reinforced soil body; cutting fluid is injected into the to-be-reinforced soil body through the grouting pipe so as to cut the to-be-reinforced soil body to form a slurry pumping area; gravel slurry generated in the slurry pumping area is pumped away; and during slurry pumping, pouring slurry is injected into the slurry pumping area through the slurry injection pipe, so that a reinforcing body is formed after solidification in the slurry pumping area. The whole process is monitored by the sensor and the geophysical prospecting device, the power device and the grouting holes are controlled to complete construction according to design requirements, and the artificial intelligence function is achieved. According to the method, under the condition that disturbance to an existing building is small, an original soil body in a building foundation is rapidly replaced with a raft foundation with larger bearing capacity, and the technical problem that an integral reinforced raft foundation or a box type foundation cannot be formed below the existing building in the prior art is solved; the bearing capacity of the building foundation is remarkably improved, and the stability of the building foundation is improved.
本发明具体公开了一种建筑筏板基础的智能注浆施工方法及施工设备，施工方法包括将注浆管贯穿待加固土体；通过注浆管向待加固土体注入切割液，以切割待加固土体形成抽浆区；抽走抽浆区内产生的砂石泥浆；在抽浆的同时，通过注浆管向抽浆区注入灌注浆，以在抽浆区固化后形成加固体。全过程由传感器和物探装置监控,并控制动力装置和注浆孔按设计要求完成施工，具有人工智能功能。本发明实现了在对既有建筑扰动小的情况下，快速将建筑物地基中的原土体置换成具有更大承载力的筏板基础，解决了目前现有技术无法在已有建筑下方形成整体式的配筋筏板基础或箱式基础的技术问题，使建筑物地基的承载能力得到显著提升，提高了建筑物地基的稳固度。
