Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, the utility model provides a kind of high slope rockmass structure, side slope mainly adopts three rank to put slope, each step is high 8 meters, platform is wide 2 meters, namely comprise set gradually from the bottom to top the first slope, rank 1, second-order slope 2 and the 3rd slope, rank 3, the gradient on the first slope, rank 1, second-order slope 2 and the 3rd slope, rank 3 is followed successively by 1:0.5,1:0.75 and 1:1, the domatic shotcrete layer on the first slope, rank 1, second-order slope 2 and the 3rd slope, rank 3, the first slope, rank 1, second-order slope 2 and the 3rd slope, rank 3 all adopt the supporting and protection structure of prestressed anchor framework 4 and rhombus skeleton 5.
Slope drainage system comprises the gutter being arranged on top, slope, and toe arranges gutter in conjunction with road drainage system, and slope body (the first slope, rank 1, second-order slope 2 and the 3rd slope, rank 3) arranges water-permeable pipe by 3500x3500 spacing, flare 10%.
The scheme of slope greening is: in prestressed anchor framework 4, adopt greening soil blocking bag bank protection or grass planting, adopts soft protecting net 6 front cover simultaneously.
The order of the utility model when Specific construction is, slope excavation → side slope cleaning → erection construction platform → anchor bolt construction → drain hole construction → side slope pipe laying ejectment water → m esh-hanging sprayed concrete → prestress anchorage cable.Do concrete introduction below:
1, slope excavation: adopt reverse construction.The sequence of construction of slope excavation is: during excavation from top to bottom, longitudinal kerve, horizontal partition, stage excavation.Each lift height is 3-4M.
2, side slope cleaning: adopt after marching into the arena and manually know side slope amount and loosening rock from top to bottom.Chisel out fritter loosen, suspension rock, reach construction smooth.
3, erection construction platform: engineering scaffold adopts steel pipe scaffold to set up.This engineering belongs to high slope engineering, and erection construction platform adopts bamboo springboard to set up.Setting up berm width is 2 meters, and every layer height is 2 meters, peripheral hardware guard rail.Scaffold and putting up platform want firm, have anti-impact force, anti-vibration ability.
4, vertically to drain off floodwaters pipe construction method: pipe junction of drainning off floodwaters on vertically drain off floodwaters pipe and ground adopts to refute with C25 steel concrete and connects well and be connected, refuting and connecing well head footpath is 1000 ㎜, refute to connect after well construction when concrete and just connect aboveground mouth φ 1000C60 concrete pipe is installed refuting, to carry out filling ensureing drainning off floodwaters at surrounding installation form pouring C15 concrete after two joint concrete pipes are often installed the stability of pipe, after top layer concrete pipe and packed layer pouring, blockage drains off floodwaters pipe draining in case the foreign material weeds flowing water at massif upper reaches drains off floodwaters to require to install cast iron grate at top layer concrete pipe well mouth.
