Freezing process channel construction technology
The invention belongs to the field of freezing process construction, and relates to a freezing process channel construction technology. The freezing process channel construction technology comprises the following steps including excavation, preliminary bracing, concrete spraying, waterproof layer construction, formwork erecting and pouring construction. The freezing process channel construction technology is good in safe reliability, capable of effectively isolating underground water, wide in adaptive face and suitable for any loose rock-soil layer containing a certain water content, and the freezing technology is effective and feasible in complex hydrogeology such as soft soil, a soil layer containing instable water, drifting sand, high water pressure and high ground pressure stratum conditions; flexibility is good, the shape and the expansion range of a frozen body can be artificially controlled, and freezing can be conducted bypassing underground obstacles in necessary; controllability is good; frozen solidified soil bodies are uniform and complete; and pollution is little, a green construction method conforms to the environmental geotechnical engineering development tendency.
本发明属于冻结法施工领域，涉及一种冻结法通道施工工艺，包括以下步骤：开挖；初期支护；喷射混凝土；防水层施工；立模；浇筑施工。本发明安全可靠性好，可有效的隔绝地下水；适应面广：适用于任何含一定水量的松散岩土层，在复杂水文地质如软土、含水不稳定土层、流砂、高水压及高地压地层条件下冻结技术有效、可行；灵活性好：可以人为地控制冻结体的形状和扩展范围，必要时可以绕过地下障碍物进行冻结；可控性较好：冻结加固土体均匀、完整；污染性小：“绿色”施工方法，符合环境岩土工程发展趋势。
