Embodiment 1

[0093] Such as Figure 1-4 As shown, a sash beam support system for expansive soil slope, the system includes a prefabricated sash beam 1 and an anchor rod 2 . The assembled sash beam 1 includes a fixing piece 11 , a connecting piece 12 and an assembled beam member 13 . The fixing part 11, the connecting part 12 and the assembled beam member 13 are all multi-layered in the direction perpendicular to the slope surface, and the multi-layer fixing part 11 is between layers and between layers. Horizontal elastic members 14 are provided between the layers of the assembled beam member 13 and between the layers of the multi-layer connectors 12 . The multi-layer prefabricated beam members 13 are connected with the multi-layer fixing parts 11 through the multi-layer connecting parts 12 to form the multi-layer prefabricated sash beam 1 . The anchor rod 2 anchors the multi-layer assembled sash beam 1 through the multi-layer fixing member 11 .

Embodiment 2

[0095] Repeat Example 1, such as Figure 5 As shown, only the multi-layer fixing member 11 is a double-layer structure. The double-layer fixing member 11 includes an upper fixing component 1101 and a lower fixing component 1102 . The upper fixing assembly 1101 is arranged above the lower fixing assembly 1102, and a horizontal elastic member 14 is arranged at the overlap between the two. A reserved anchor hole 1103 is also provided on the upper surface of the double-layered fixing member 11 , and the reserved anchor hole 1103 passes through the upper fixing component 1101 , the horizontal elastic member 14 and the lower fixing component 1102 sequentially from top to bottom. Preferably, the upper fixing assembly 1101 and the lower fixing assembly 1102 are vertically symmetrical rigid components.

Embodiment 3

[0097] Embodiment 2 is repeated, except that splicing grooves 1104 are provided on all sides of the double-layered fixing member 11 . The joining groove 1104 includes an upper groove 110401 and a lower groove 110402 . Upper grooves 110401 are provided on the lower ends of all sides of the upper fixing assembly 1101 . Lower grooves 110402 are provided on the upper ends of all sides of the lower fixing assembly 1102 . The upper groove 110401 on any side of the upper fixing component 1101 and the lower groove 110402 on the side of the lower fixing component 1102 on the same side together form a splicing groove 1104 .

Abstract

The invention discloses a frame beam supporting system for an expansive soil slope and a construction method of the frame beam supporting system. The frame beam supporting system comprises an assembly type frame beam and an anchor rod. The assembly type frame beam comprises a fixing piece, a connecting piece, an assembly type beam component and an elastic piece. By means of the assembly type characteristic, rapid dry construction can be conducted on site, and the construction efficiency is improved; and the elastic piece is additionally arranged in the frame beam, the problem of large-area expansion deformation of the expansive soil slope is solved, the construction pressure of slope engineering is effectively relieved, and the stability of the expansive soil slope is effectively kept. According to the assembly type frame beam supporting structure of the frame beam supporting system, the design of novel splicing joints, a splicing manner and the embedded elastic piece is adopted, the influence of slope deformation on the stability of the assembly type frame beam is improved, and the frame beam protection effect is improved.

Description

technical field [0001] The invention relates to slope protection engineering equipment, in particular to a sash beam support system for expansive soil slopes and a construction method thereof, belonging to the technical field of slope protection. Background technique [0002] Expansive soil is a kind of soil that is widely distributed in my country and is prone to disasters. Because of its expansion and contraction, over-consolidation and fissures, its engineering properties have its own characteristics compared with ordinary cohesive soils, so the stability calculation of slopes and the selection of treatment programs are also different from those of other types of soil slopes. , in particular, it has two deformation characteristics of obvious water absorption expansion and water loss shrinkage, which are likely to have adverse effects on the use of slope protection equipment. At present, the commonly used landslide treatment schemes for expansive soil slopes in China incl...
