Large-thickness collapsible loess subgrade structure in seasonal frozen area and construction method of large-thickness collapsible loess subgrade structure
The invention discloses a large-thickness collapsible loess roadbed structure in a seasonal frozen area and a construction method of the large-thickness collapsible loess roadbed structure. The large-thickness collapsible loess roadbed structure in the seasonal frozen area comprises a reservoir, a main drainage pipe, a pressure water injection pump, an isolation plate, a support, a sleeve, an upper water injection pipe, a secondary drainage pipe, a bottom plate, a support, a cover plate, supporting legs, a soaking pit, a sleeve, a lower water injection pipe, a flow speed controller, a clamping groove and a clamping seat. The water injection system adopts a novel sleeve and a water injection pipe; during pre-soaking, the water injection pipe is easy to block, and the water injection pipe is not easy to block during water injection due to dual protection of the sleeve and the water injection pipe; the support, the cover plate, the sleeve, the bottom plate and the isolation plate form an integral structure, when a soil body is subjected to pre-impregnation collapse, loading can be carried out on the bottom plate according to engineering conditions, the collapse efficiency is improved, meanwhile, the collapsibility of the shallow soil body is treated, and the cover plate on the sleeve can prevent sundries from entering the sleeve to affect construction.
本发明公开了一种季冻区大厚度湿陷性黄土路基结构及其施工方法，该季冻区大厚度湿陷性黄土路基结构包括蓄水池、主排水管、压力注水泵、隔离板、支架、套筒、上部注水管、次排水管、底板、支座、盖板、支腿、浸水坑、套筒、下部注水管、流速控制器、卡槽和卡座；本发明的注水系统采用新型套筒和注水管；在预浸水的时候，注水管很容易发生堵塞，用套筒加上注水管的方法，双重防护，使注水时不容易堵塞注水管；本发明的支架、盖板、套筒、底板以及隔离板形成一个整体的结构，当土体发生预浸失陷时，根据工程情况，可在底板上堆载，加快失陷效率，同时处理浅层土体的湿陷性，套筒上的盖板可防止杂物进入套筒内影响施工。
