Acid-soluble drilling drainage structure of karst or faulted tunnel and side slope and construction method
The invention relates to the field of civil engineering, and discloses a drainage structure of a karst or a faulted tunnel and a side slope and a construction method. The acid-soluble drilling drainage structure comprises a permeable section and a grouting section, the permeable section is located on the lower portion of a downwards-inclined drill hole, the grouting section is located on the upper portion of the drill hole, a water stop component is arranged between the permeable section and the grouting section, a permeable pipe is arranged in the permeable section, a cavity is formed in the permeable pipe. A water drainage pipe penetrating through the water stop component and extending outwards is arranged in the permeable pipe, the permeable pipe is filled with solid filling materials soluble in acid and insoluble in water, and the lower portion of the water stop component, the permeable pipe and the water drainage pipe are all made of acid-resistant materials or provided with acid-resistant surface layers. According to the drainage structure of the karst or the faulted tunnel and the side slope and the construction method,, construction controllability of the drainage structure can be improved while a grouting pressure is guaranteed.
本发明涉及土木工程领域，公开了一种岩溶或断层的隧道及边坡的排水结构及施工方法。本申请的酸溶钻孔排水结构，包括透空段与注浆段，所述透空段位于下倾的钻孔的下部，所述注浆段位于所述钻孔上部，所述透水段与注浆段之间设置止水构件，所述透水段内设有透水管，所述透水管内具有空腔，所述透水管内设置有穿过止水构件向外延伸的排水管，所述透水管内填充有可溶于酸且不可溶于水的固体填充材料，所述止水构件下部、透水管以及排水管均为耐酸材质或者具有耐酸表层。通过该排水结构及施工方法可以保证注浆压力的同时，提高排水结构施工的可控性。
