Abstract

The invention discloses a drainage composite self-drilling tire stringed bolt supporting structure and a construction method. The drainage composite self-drilling tire stringed bolt supporting structure aims to improve the stability of soft slopes and structurally comprises drainage boards, lattice beams, face boards and self-drilling tire stringed bolts. The self-drilling tire stringed bolts comprise hollow bolts, tires and drilling rods which are connected with one another; the drainage boards are drilled into soil from the tops to the bottoms of the slopes, and the self-drilling tire stringed bolts are constructed into the slopes from vertical slope surfaces between the two rows of drainage boards; the face boards and the lattice beams which perpendicularly intersect with one another are sequentially arranged on the slope surfaces, and the self-drilling tire stringed bolts penetrate the face boards and the lattice beams. The drainage composite self-drilling tire stringed bolt supporting structure has the advantages that air can be inflated into the self-drilling tire stringed bolts, accordingly, the tires can be expanded to squeeze the surrounding soil and can be anchored in stable strata, the self-drilling tire stringed bolts can be anchored at cross positions of the lattice beams by anchors and steel base boards, the spatial support structure can be formed, and the unstable soft soil can be anchored in the stable strata.

Description

technical field [0001] The invention belongs to the technical field of anchoring and is used for supporting projects such as slopes and foundation pits in soft soil regions. Background technique [0002] With the rapid development of economic construction, especially the rapid development of infrastructure construction in my country's coastal areas, and the soil in coastal areas is mostly soft soil, urban land space is extremely scarce, so the construction of underground space, roads and railways in this area has produced many Weak soil slope. Soft soil has a high water content, is usually in a soft plastic or flow plastic state, has poor physical and mechanical properties, and the slope engineering of the foundation pit is easily deformed or even collapsed, which makes the treatment of soft soil slopes difficult. [0003] At present, the technologies and corresponding advantages and disadvantages of treating weak soil slopes are mainly summarized into the following categori...
