Abstract
Description
Technical Field
[0001] The invention relates to the technical field of slope scaffolding erection, in particular to a construction method for erecting a high, steep and loose slope scaffolding. Background Art
[0002] The main method of stabilizing the slope of infrastructure is anchor lattice structure. The construction of anchor lattice structure requires the construction of scaffolding platform. The existing scaffolding construction method of slope is mainly double-row frame, and the slopes are all mechanically brushed. After brushing, the slope surface is relatively regular, the slope is gentle and the slope is uniform. The construction can also be carried out in layers according to the level of the slope. However, there are some high, steep and loose slopes. These slopes have the following characteristics: (1) The slopes are mainly damaged and repaired existing slopes. There is no brushing condition, and the slope shape cannot be changed; (2) The slopes are high and steep, with a height of more than 100m and a maximum steepness of 80°; (3) The slopes are relatively loose and there is a risk of collapse. Therefore, when the existing slope scaffolding construction method is used to construct high, steep and loose slopes, there will be a large reaction force during the drilling of the super-long anchor rods, and the stability of the scaffolding is difficult to guarantee. Summary of the invention
[0003] In view of the deficiencies in the prior art, the present invention provides a construction method for erecting scaffolding on high, steep and loose slopes, so as to solve the technical problems in the related technology that when the existing slope scaffolding is used to erect high, steep and loose slopes, there will be a large reaction force during the drilling construction of extra-long anchor rods, and the stability of the scaffolding is difficult to ensure.
[0004] The present invention provides a construction method for erecting a scaffold on a high steep loose slope, comprising:
[0005] S1. Slope treatment:
[0006] The dangerous rocks on the slope are cleared manually, and then the entire slope is sprayed with concrete to ensure the stability of the slope;
[0007] S2. Cushion treatment:
[0008] The concrete is poured in steps, the cushion is hardened, and then the poles are set on the pad to ensure the levelness of the cushion and the stability of the poles.
[0009] S3. Scaffolding erection:
[0010] The scaffolding is erected in four rows, and according to the actual slope shape, it is gathered from the outside to the inside, and is erected in layers, with the crossbars against the slope;
[0011] S4. Treatment of the bottom of the pole:
[0012] According to the amount of space available on the slope, two methods were used:
[0013] One is that the slope is gentle and there is enough space, so the slope is directly chiseled flat to ensure that the pole is in full contact with the slope;
[0014] One is that the slope is steep and the bottom of the vertical pole is not in enough contact with the slope. The L-shaped steel bar is driven into the slope soil, mortar is poured, and the vertical pole is put on the steel bar;
[0015] S5. Layout of slope-connecting diagonal rods:

Anchor rod holes are drilled on the slope surface. The anchor rod holes need to reserve ballast sections. The prefabricated auxiliary anchor rods are inserted into the holes. A limited tripod bracket is welded on the auxiliary anchor rods. Then, anchor mortar is injected. After the anchor body is solidified, the auxiliary anchor rods are connected to the adjusting rod threads. The adjusting rods are connected to the extended anchor rod threads. The extended anchor rods are connected to the connecting steel pipes by single-sided welding. Finally, the connecting short steel pipes are connected to the nodes of the scaffolding frame through rotating fasteners.

[0020] (1) Drilling rig location
[0021] Before drilling, according to the position of the drilling rig, temporarily add a longitudinal horizontal bar at the top or tail of the drilling rig, and firmly connect it with the vertical bars on both sides of the span with right-angle fasteners;
[0022] (2) Wall connection
[0023] When constructing the upper anchor bolt, use inclined steel pipes to connect with the steel pipes at the lower wall connection parts, and the inclined steel pipes are set up with the anchor drilling rig;

Guardrails and high footboards are set on the construction operation layer outside the scaffolding. The railings and footboards are set on the inner side of the outer poles.
[0026] According to the progress of on-site construction, multiple zigzag ramps are set up at intervals. The ramps are fully covered with scaffolding, and platforms are set up at the corners. Guardrails and footboards are installed on both sides of the ramp and the periphery of the platform. The upper and lower passages are fixed with wall connecting rods and unloading devices as required, and red warning lights are installed at the corners of the passages.

[0030] Furthermore, in S5, the slope connecting rod is 15-25 cm away from the bottom of the vertical rod.
[0031] Furthermore, in S6, the wall connecting member is a φ20-30 threaded steel bar, and a φ40-50 mm anchor hole is drilled on the slope surface, and a 45-55 cm slag section needs to be reserved for the anchor hole.
[0032] Furthermore, in S8, multiple protective railings and 15-20 cm high footboards are set at 0.3-09m and 1-1.5m height positions on the construction working layer outside the scaffolding.

[0035] Furthermore, in S8, the height of the handrail is 1-1.5m, and the height of the footboard is 17-20cm.
[0036] Compared with the prior art, the present invention has the following beneficial effects:
[0037] (1) Wide applicability. The length of the wall connecting piece can be adjusted by the adjusting rod to adapt to the uneven slope surface. The layout of the wall connecting piece and the subsequent reinforcement measures greatly improve the safety of drilling.

[0084] Example 2
[0085] See also Figures 1 to 8 The embodiment of the present invention provides a construction method for erecting a scaffold on a high steep loose slope, comprising:
[0086] S1. Slope treatment
[0087] In view of the loose and easy collapse characteristics of the slope, we first adopted the method of manual clearance to clear the dangerous rocks on the slope, and then sprayed 3cm of C25 concrete on the entire slope to ensure the stability of the slope;
[0088] S2. Cushion treatment
[0089] The foot of this type of slope is mostly irregularly linear with a large longitudinal slope. To ensure the horizontality of the cushion layer and the stability of the pole 22, the cushion layer is cast in steps. The cushion layer is hardened with C20 concrete, with a thickness of not less than 10cm, a single step span of not less than 2 spans, and a single step height of 5-15cm (depending on the actual terrain). The pole 22 must be set on a pad, which is a wooden pad with a length of not less than 2 spans, a thickness of not less than 50mm, and a width of not less than 200mm.
[0090] S3. Scaffolding erection
[0091] Considering the steepness and height of the slope and the load parameters of the drilling rig, the scaffolding is erected in four rows, and according to the actual slope shape, it is gathered from the outside to the inside, and is built in layers to reduce the overall stress height. The horizontal distance is 0.9m+0.9m+0.9m, the crossbar 23 is against the slope, and the distance between the scaffolding and the slope is 0.3m; the vertical distance is 1.5m, and the step distance is 1.5m;
[0092] S4, measures at the bottom of pole 22
[0093] There are two ways to implement it according to the amount of space on the slope. One is that the slope is gentle and the space is sufficient, and the slope is directly chiseled flat, with a range of 10cm×10cm, to ensure that the vertical pole 22 is in full contact with the slope. The other is that the slope is steeper, and the bottom of the vertical pole 22 is not in sufficient contact with the slope area, so L-shaped steel bars are driven into the slope soil, and M30 mortar is poured, with an anchoring length of not less than 2m, and the vertical pole 22 is put on the steel bars;
[0094] S5, Layout of slope connecting rod 24
[0095] In order to prevent the partial vertical pole 22 from hanging in the air and maintain the overall stability, a slope connecting inclined rod 24 is arranged along the slope surface, which is set on the vertical pole 22, parallel to the slope surface, and 20 cm away from the bottom of the vertical pole 22;
[0096] S6. Layout of wall connection piece 10
[0097] The wall connecting member 10 is arranged in two parts and three spans. The wall connecting member 10 is a φ25 threaded steel bar 11 (auxiliary anchor rod). A φ45mm anchor rod hole 30 is set on the slope surface. The anchor rod hole 30 needs to reserve a 50cm ballast section 15; the prefabricated auxiliary anchor rod is inserted into the hole, and a limited tripod bracket 18 is welded on the auxiliary anchor rod. The bracket is composed of φ8 round steel bars, which can not only play the role of centering the anchor rod, but also increase the anchor rod limiting capacity; then inject anchor mortar, requiring M30 cement mortar 12; after the anchor body strength reaches 75%, the auxiliary anchor rod is threadedly connected to the adjusting rod 16; the adjusting rod 16 is threadedly connected to the extension anchor rod 17; the extension anchor rod 17 is connected to the connecting steel pipe 13 by single-sided welding; finally, the connecting short steel pipe is connected to the node of the scaffold frame 20 by the rotating fastener 14;
[0098] S7. Strengthening measures during drilling rig construction
[0099] (1) Drilling rig location
[0100] Since the anchor drilling rig needs to be placed at an angle, in order to bear the reaction force during drilling operation, before drilling, a longitudinal horizontal rod 21 is temporarily added at the top or tail of the drilling rig according to the position of the drilling rig, and is firmly connected to the vertical rods 22 on both sides of the span with right-angle fasteners;
[0101] (2) 10 wall connections
[0102] To ensure safety, when constructing the upper anchor bolt, use inclined steel pipes to connect with the steel pipes at 10 locations of the lower wall connection parts, and the inclined steel pipes are set up with the anchor drilling rig;
[0103] S8, operating floor and ramp
[0104] The operation layer is fully covered with scaffolding boards, which are set on three horizontal bars 21. The scaffolding boards are laid in a butt-jointed manner. Two protective railings and 18cm high footboards are set at 0.6m and 1.2m high positions on the outer side of the scaffolding construction operation layer. The railings and footboards should be set on the inner side of the outer poles 22.
[0105] To facilitate personnel to go up and down the working surface, according to the progress of on-site construction, a zigzag ramp is set up every 40-60m. The width of the ramp is 1m, the slope is 1:3, the ramp is fully covered with scaffolding, and an anti-slip wooden strip is added every 30cm horizontally. The thickness of the wooden strip is 2-3cm. A platform with a width of 1m is set at the corner. Guardrails and toeboards are installed on both sides of the ramp and the periphery of the platform. The height of the railing is 1.2m, and the height of the toeboard is 18cm. The upper and lower channels are fixed with wall connecting rods and unloading devices as required, and red warning lights are installed at the corners of the channel.
[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
