Abstract

The invention discloses a porous steel pipe combined skeleton grouting karst cave filling structure and a construction method. The porous steel pipe combined skeleton grouting karst cave filling structure is characterized in that a relatively flat concrete base is arranged at the bottom of a karst cave; porous steel pipe combined skeletons above are fixed to the base through a support; the poroussteel pipe combined skeletons are filled with stone blocks; and injected cement mortar is distributed in clearances and steel pipes. The construction method comprises the steps of pouring the concretebase; selecting suitable guide pipes; laying the porous steel pipe combined skeletons; laying wall bodies; filling the stone blocks; and pouring cement mortar. According to the porous steel pipe combined skeleton grouting karst cave filling structure and the construction method, the defects that a side entrance of a conventional karst cave is lower than a jaw-shaped slope karst cave filling structure and defects of a conventional construction method are well overcome, the purpose that the entire karst cave is completely filled as much is possible is achieved, and the porous steel pipe combined skeleton grouting karst cave filling structure has the advantages that construction is normative, quick, convenient and economic, construction efficiency is high, and the structure is safe and stable.

Description

Technical field [0001] The invention relates to the field of shallow buried karst cave filling, in particular to a grouting karst cave filling structure and a construction method with a composite skeleton of a steel pipe with holes. technical background [0002] Karst landforms are widely distributed in China. With the development of road transportation in China, more and more karst caves have appeared. Among them, the treatment of shallow-buried slope karst caves has also attracted more and more people's thinking-how to make it simple and yet Dispose of it safely. [0003] Nowadays, the treatment methods for shallow-buried karst caves on slopes are mostly the treatment method of vault karst caves with top openings, or the treatment method of karst caves with side openings and the height of the opening is higher than the top of the karst cave, but for the side opening and the opening is obvious It is difficult to have a simple, economical and sufficiently safe and stable method fo...
