Problems solved by technology

In order to completely eliminate the above-mentioned roadblocks, it is necessary to rely on large-scale machinery and equipment and even blasting operations to completely clear the entire road. If the road where the above-mentioned roadblocks appear is 100 kilometers long and there is no third road connection in the middle, these large-scale machinery and equipment will The equipment can only go from the two ends of the 100 kilometers to the middle of the road, one roadblock is removed one by one, and it is pushed forward bit by bit. This is the only way for large-scale machinery and equipment to reach every mountain collapse point. In this way It will take a long time to rush through the entire road, which will greatly delay the effective time for rescuing the injured and delivering relief materials. It is a very helpless solution

Embodiment 1

[0020] Type A: Protective Shed and Construction Method for Preventing Flying Stones from Falling

[0021] Consisting of uprights, beams, and oblique beams, it is characterized in that: the reinforced concrete foundations of the inner and outer steel pipe columns are respectively constructed in the section of the mountainous road 1 where flying stones are prone to fall, and on the outer shoulder, and the fixing screw 14 of the steel pipe column is pre-embedded; The inner and outer steel pipe columns are respectively installed on the inner and outer fixed screw rods 14 through nuts, and the distance between the inner steel pipe column 5 and the outer steel pipe column 4 is set to 6.5m-8.5m;

[0022] The upper end of the inner steel pipe column 5 and the top of the outer steel pipe column 4 horizontally erect a spanning steel girder 7, the height of the spanning steel girder and the road surface is set to 3.5m-4.5m, and a slope beam 8 is erected on the spanning steel girder; Th...

Embodiment 2

[0025] Type B: Protective Shed and Construction Method for Preventing Flying Stones from Falling

[0026] The protective shed and the construction method of this type to prevent the falling of flying stones are basically the same as the structure of embodiment 1, the difference is only that: the inner side slope of the road is very steep, and the rocky road section where the cliff is in a vertical state does not need to set up the inner steel pipe column 5, Directly on the inner rock at the corresponding height of the outer steel pipe column 4, a plurality of long-stem bolts 12 are implanted along the road, and longitudinal steel beams 13 are erected on the long-stem bolts, and the long-stem bolts 12 and the longitudinal steel beams 13 are connected by nuts or Welding; the distance between the outer steel pipe column 4 and the rock slope in the vertical state of the inner side is 6.5m-8.5m; The longitudinal steel girders 13 are connected into a whole by bolts or welded to fo...

Abstract

The invention provides a protective shed preventing falling flying stone and a construction method of the protective shed. The protective shed preventing the falling flying stone is composed of stand columns, transverse beams and inclined beams and is characterized in that the inner side steel pipe stand columns and the outer side steel pipe stand columns are arranged on the inner side road shoulder and the outer side road shoulder of a section, where the flying stone falls off easily, of a mountainous road, and the distance of each stand column ranges from 6.5m to 8.5m; the upper ends of the outer side steel pipe stand columns are horizontally provided with transverse cross steel beams in an erected mode, the distance between each transverse cross steel beam and the ground ranges from 3.5m to 4.5m, and the transverse cross steel beams are provided with slope beams in an erected mode; a plurality of inclined supports are connected or welded among the inner side steel pipe stand columns, the outer side steel pipe stand columns, the transverse cross steel beams and the slope beams through bolts, and therefore the inner side steel pipe stand columns, the outer side steel pipe stand columns, the transverse cross steel beams and the slope beams form supporting frames of the protective shed; the inner side steel pipe stand columns and the outer side steel pipe stand columns of the supporting frames are connected through shear shanks to form a section of the protective shed, the slope beams of the supporting frames are provided with longitudinal cross steel beams in an erected mode, and a plurality of protective boards are laid on the longitudinal cross steel beams to form a whole protective surface. The protective shed preventing the falling flying stone has the advantages that the flying stone is prevented from obstructing the traffic, space is formed for safe passage of vehicles in a supported mode, and the road is kept unblocked at any time.

Description

technical field [0001] The present invention relates to the construction of protective facilities for road traffic. It adopts a special protective measure on a special road section of the main traffic line to support a space for the safe passage of vehicles. To be precise, it is a protective shed and Construction method. Background technique [0002] At 8:02 on April 20, 2013, a magnitude 7.0 earthquake occurred in Lushan County, Ya'an City, Sichuan Province (30.3 N, 103.0 E). The focal depth was 13 kilometers. The epicenter is about 100 kilometers from Chengdu. Strong tremors were felt in Chengdu, Chongqing, and Baoji, Hanzhong, and Ankang in Shaanxi. According to a report from the Ya'an Municipal Government Emergency Response Office, more than 99% of the houses in Longmen Township, Lushan County, the epicenter, collapsed. The health center and inpatient department stopped working, and water and electricity were cut off. The affected population was 1.52 million, and the...
