Embodiment Construction
[0031] The present invention will be described in detail below in combination with specific embodiments.
[0032] The invention relates to a combined rock-block wall structure for protecting dangerous rockfalls on high and steep slopes, including a lower structure and an upper structure. The lower structure includes a supporting wall pier body 3, a horizontal roof 4 and its top filling, and the upper structure includes a longitudinal rock wall panel 5, a transverse rock wall rib 7 and an anchor cable 8.
[0033] Described structure is specifically:
[0034] It includes support wall-type piers 3 vertically arranged in a row on one side of the high and steep slope, a vertical horizontal roof 4 is arranged above the support wall-type pier 3, and an upright vertical rock wall panel 5 is vertically arranged above the horizontal roof 4. Between the outer side of the stone wall panel 5 and the horizontal roof 4 and the high and steep slope, there are multiple transverse stone wall r...

The invention relates to a high and steep slope dangerous rock rockfall protection method and combined rock bearing wall structure thereof.The combined rock bearing wall structure of the high and steep slope dangerous rock rockfall protection method comprises supporting walltype pier bodieslongitudinally arranged in a row on one side of a highsteep slope, horizontal roof platesarelongitudinally arranged above the supporting wall type pier bodies, upstanding longitudinal rock bearing wall panels are longitudinally arranged above the horizontal roof plates, a plurality of transverse upstanding rock bearing wall ribs transversely perpendicular to a slope surface are arranged between the outer side of the longitudinal rock bearing wall panels and the high and steep slope. According to the highand steep slope dangerous rock rockfall protection method and combined rock bearing wall structure thereof, an engineering structure composed of reinforced concrete members is adopted to deal with the problem of the high and steep slope dangerous rock rockfall protection, the problems of high construction cost of building multiple shed tunnels, low protection height of the rock bearing structureon a steep slope, and crossing of rockfall are solved.
Description
technical field [0001] The invention belongs to the technical field of traffic construction, and in particular relates to a method for protecting dangerous rockfalls on high and steep slopes and a combined rock-blocking wall structure. Background technique [0002] The construction of railways inevitably encounters dangerous rockfalls on high and steep slopes. In the mountainous areas of southwest my country and Tibet, the terrain of high and steep slopes is steep, and a large number of dangerous rockfalls are distributed, which has a great impact on operational safety. [0003] The rockfall protection of railways and highways mostly adopts structures such as brush slopes, metal rock nets, tunnel open holes, multi-line shed holes, gravity rock walls, pile plate rock walls, and rail fences. The calculation of the rockfall trajectory shows that the rockfall trajectory will hit the newly built parallel multi-strand roads on the station subgrade of the newly-built parallel 8-str...
