Detailed Description
As shown in fig. 1 to 5, a surrounding rock supporting structure of a large underground cavern comprises reinforcing mechanisms respectively arranged on two side walls of an arc-shaped cavern 1. Every strengthening mechanism all includes two pre-buried framves 2 from top to bottom, and the outside is fixed with a plurality of vertical braces 3 between two pre-buried framves 2, and a plurality of vertical braces 3 are along the equidistant interval arrangement of horizontal direction. V-shaped reinforcing plates 5 are arranged between every two adjacent vertical frames 3 at equal intervals along the vertical direction. 2 tops of pre-buried frame above two reinforcing mechanism all have seted up spout 12 along length direction about, and the equal sliding connection in inboard of spout 12 has a plurality of sliders, controls just right two sliders and be a set of, and all installs arc frame 8 jointly with the slider top of group, and the top of multiunit arc frame 8 is all installed along the arc orbit equidistance and is supported seat 7, supports the inboard arc roof of seat 7 top at arc cavern 1.
Preferably, through grooves 6 are formed in each vertical frame 3, embedded bolts 9 are embedded in the arc-shaped cavern 1, and the positions of the embedded bolts 9 correspond to the positions of the through grooves 6. The outside screw thread cover at pre-buried bolt 9 is equipped with nut 10, the tip of pre-buried bolt 9 extends to the inboard of arc grotto 1, pre-buried bolt 9 through setting up can be convenient for fix pre-buried frame 2, pre-buried bolt 9 is when the in-service use, can use the special toper pre-buried bolt 9 of rock of high strength metal preparation to the rock wall, this pre-buried bolt 9 joint strength is higher, and be applicable to and bore the dress to the rock, the effect of getting up in the use is stronger, and can carry out rust-proof spraying to pre-buried bolt 9 and nut 10 in the later stage use, thereby avoid causing the outside to rust the problem that influences the use in the underground use.
Preferably, a plurality of fixing posts 4 are mounted on the outer sides of the vertical frames 3 at both ends of the left and right reinforcing mechanisms. And a plurality of fixed columns 4 are arranged along vertical direction equidistance, install a plurality of fixed columns 4 in the 3 outsides of the perpendicular frame that are close to both ends border, can be convenient for the later stage to arc cavern 1's lateral wall adding one deck rock maintenance net to avoid causing the stone to drop because phenomenons such as cliff fracture, weigh down the problem that causes accident.
Preferably, hug closely arc cavern 1 lateral wall in the inboard of every pre-buried frame 2 and be provided with drainage mechanism, drainage mechanism is including all seting up the water storage cavity 15 in 2 inboard top positions of pre-buried frame, and 2 side edges of pre-buried frame are terminal surface 14 for the inclined plane, and water storage cavity 15 both ends have seted up seepage hole 13. It is in order to carry out the drainage in the water droplet on the rock wall under the conventional state to set up water storage cavity 15 through the top at pre-buried frame 2, normal underground works is because underground temperature and earth's surface temperature's difference, the rock wall top layer of underground building has a large amount of water droplets to depend on in its rock wall outside, wait to assemble the back according to gravity nature whereabouts, in order to avoid influencing pre-buried frame 2 and the use of many pre-buried bolts 9, wait that the water droplet shaping just falls to water storage cavity 15's inboard along the rock wall, then the seepage hole 13 of seting up through pre-buried frame 2's both ends will persist water, flow out from both ends.
Preferably, be fixed with extension 11 on the 8 inner walls of arc frame, the appearance of extension 11 is the arc setting, the arc frame 8 through setting up can be convenient for carry out the erection bracing that corresponds to the modeling of arc grotto 1 top, thereby strengthen strutting the rock wall at arc grotto top, extension 11 can be in the top rock maintenance net that the 1 top of outer frame dress arc grotto was used, use the rock maintenance net of this and lateral wall department to make up, in the in-service use in later stage, can laminate the face of extension 11 on the 8 inner walls of each arc frame with top rock maintenance net, then make the stable installation of top rock maintenance net on the extension 11 of the 8 positions of corresponding arc frame through the mounting of outside use.
The working principle is as follows: before using, can realize observing the rock layer at the inboard top of arc cavern 1, then when the installation, through the selection of the hard bellied rock piece of avoiding that corresponds, remove and slide at the inboard arc frame 8 of pre-buried frame 2 in top, a plurality of seats 7 of supporting in the arc frame 8 outside support when the inboard top of arc cavern 1, the inboard of pre-buried frame 2 is pegged into to the pre-buried 9 cartridge of corresponding, can install pre-buried frame 2. The installation is fixed the back, at first correspond extension board 11 on the 8 inner walls of arc frame with outside cliff maintenance net again and install it, the cliff maintenance net accessible both ends border department of lateral wall erects the multiunit fixed column 4 in the 3 outsides of frame then with its enclose dress, from this, overall structure obtains improving more step to the protectiveness of cliff, in the later stage use, the water droplet on the cliff can fall to the water chamber 15 department of depositing of 2 inboards setings of pre-buried frame that are close to the top, in order to avoid influencing the stability of 9 later stage uses of pre-buried bolt, fall in the water droplet that deposits water chamber 15 inboards, can follow the seepage flow hole 13 departments of 2 both ends setings of pre-buried frame and flow away.
