Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a liftable slope paving net-hanging spraying device and a slope spraying method. Background Art

[0002] Slope shotcrete is a commonly used method for foundation pit support, mainly used in infrastructure projects, especially in the foundation construction stage of high-rise buildings. Since the slope after foundation pit excavation needs to be reinforced to prevent landslides and collapses, shotcrete technology can spray concrete or mortar on the slope surface to form a protective layer, thereby enhancing the stability of the slope.

[0003] Net spraying is a widely used method for slope spraying. Concrete or mortar is sprayed evenly on the support net (usually steel mesh, wire mesh, etc.) by high-pressure spraying to form a stable structural surface and enhance the support effect. However, when using the existing ordinary net spraying device, the staff generally needs to hold the spraying pipe and move the spraying pipe. When the spraying pipe is in use, the staff is on the slope and it is difficult to control the spraying pipe, which may easily cause safety hazards.

[0004] Therefore, the prior art needs to be improved. Summary of the invention

[0031] Embodiment 1

[0032] Referring to Figures 1-7 as shown, the following is a description of the specific structure and principle of the liftable slope laying and shotcreting device of Embodiment 1 of the present invention.

[0033] Combined with Figure 1 as shown, the liftable slope laying and shotcreting device of Embodiment 1 of the present invention mainly includes three parts: a driving component 10, a lifting component 11, and a shotcreting component 12, and also includes auxiliary structures such as a top rod 2, a limiting rod 4, an inserting rod 3, a longitudinal steel wire 5, and a transverse steel wire 6.

[0034] In the implementation manner of this embodiment, as Figure 1 shown, the slope 1 is divided into an upper half and a lower half, and a middle platform is excavated between the upper half and the lower half. Multiple top rods 2 are evenly distributed at the top of the slope 1 and are vertically inserted and fixed from the top of the slope 1. Multiple inserting rods 3 are vertically inserted at the bottom of the slope 1, and multiple limiting rods 4 are vertically inserted on the middle platform of the slope 1. The top rods 2, the limiting rods 4, and the inserting rods 3 correspond one by one from top to bottom. A conduit 13 is welded and fixed on the outer side wall of the limiting rod 4. The top end of the longitudinal steel wire 5 is tied and fixed to the top rod 2, and then the longitudinal steel wire 5 extends downward along the slope 1, passes through the conduit 13 and continues to extend downward along the slope 1. The bottom end of the longitudinal steel wire 5 is tied and fixed to the inserting rod 3.

[0035] Furthermore, combined with Figure 1 as shown, the longitudinal steel wire 5 is connected with a transverse steel wire 6, and the intersection points of the transverse steel wire 6 and the longitudinal steel wire 5 are fixed by tying or welding. The transverse steel wire 6 and the longitudinal steel wire 5 form several squares, and a mesh-shaped auxiliary steel wire 7 is installed in the squares. The mesh cloth 9 is laid on the surface of the slope 1, below the longitudinal steel wire 5 and the transverse steel wire 6, and the mesh cloth 9 can be tied with the longitudinal steel wire 5, the transverse steel wire 6, and the auxiliary steel wire 7.

[0036] In the implementation manner of this embodiment, combined with Figure 1 andFigure 2 As shown in the figure, the driving assembly 10 is installed on the right side of the slope 1. The driving assembly 10 includes a track 1003, which can be made of channel steel and is installed from top to bottom along the slope 1.

[0037] Furthermore, Figure 3 and Figure 4 As shown in the figure, a connecting rod 1002 is fixedly connected to the left side wall of the track 1003, and a sleeve 1001 is fixed at the end of the connecting rod 1002. The sleeve 1001 is outside the ejector rod 2, realizing the connection between the ejector rod 2 and the track 1003, and the installation is very convenient.

[0038] Even further, Figure 3 As shown in the figure, a U-shaped bracket 1004 and a support plate 1005 are installed at the top of the track 1003. A sheave 1006 is installed in the middle of the U-shaped bracket 1004, and the sheave 1006 can rotate freely. A square housing 1007 is fixedly installed on the support plate 1005. Figure 3 and Figure 4 As shown in the figure, a first reduction motor 1008 is installed on the top of the housing 1007. The main shaft of the first reduction motor 1008 is connected to a worm 1009, and the worm 1009 extends into the interior of the housing 1007. And, a rotating rod 1010 is installed inside the housing 1007. A wire reel 1012 and a worm gear 1011 are fixedly installed on the rotating rod 1010. The worm gear 1011 is located inside the housing 1007 and is in mating connection with the worm 1009. The wire reel 1012 is located outside the housing 1007, and a rope 1013 is wound around the wire reel 1012.

[0039] As shown in Figure 2 and Figure 3 the figure, a slider 1014 is installed inside the track 1003. The rope 1013 extends from the wire reel 1012, bypasses the sheave 1006, and extends into the track 1003 to be connected to the slider 1014. When the first reduction motor 1008 operates, it drives the wire reel 1012 to rotate through the transmission of the worm 1009, the worm gear 1011, and the rotating rod 1010. The wire reel 1012 gradually tightens the rope 1013, thereby driving the slider 1014 to move upward along the track 1003.

[0040] It should be noted that the first reduction motor 1008 can also drive the wire reel 1012 to rotate in the reverse direction, thereby releasing the rope 1013.

[0041] In the implementation mode of this embodiment, as shown in Figure 1 and Figure 5As shown in the figure, the lifting component 11 is installed on the slider 1014. The lifting component 11 includes a mounting frame 1101, and the bottom of the mounting frame 1101 is fixedly connected to the slider 1014. The second reduction motor 1103 is installed on the top of the mounting frame 1101. The main shaft of the second reduction motor 1103 is connected to a threaded rod 1104. The threaded rod 1104 vertically extends into the interior of the mounting frame 1101. At the same time, a slide bar 1102 parallel to the threaded rod 1104 is fixedly installed in the mounting frame 1101.

[0042] Further, in combination with Figure 5 As shown in the figure, a slide plate 1105 is installed at the end of the L-shaped plate 1106. The slide plate 1105 is threadedly connected to the threaded rod 1104. At the same time, the slide plate 1105 is provided with a hole for the slide bar 1102 to pass through. When the second reduction motor 1103 works, it drives the threaded rod 1104 to rotate forward or backward. Due to the threaded connection and cooperation between the slide plate 1105 and the threaded rod 1104, the L-shaped plate 1106 is driven to rise or fall.

[0043] As Figure 5 shown in the figure, the first arc-shaped clamping plate 1107 is welded and fixed on the L-shaped plate 1106. The first arc-shaped clamping plate 1107 and the second arc-shaped clamping plate 1108 surround the grouting pipe 1201 of the grouting component 12, and then are fixedly connected by screws.

[0044] In some embodiments of this embodiment, in order to uniformly spray and grout the slope 1, in combination with Figure 6 As shown in the figure, five nozzles 1203 are installed on the grouting pipe 1201. The right end of the grouting pipe 1201 is connected to a slurry inlet pipe 1202. The slurry inlet pipe 1202 sends the sprayed slurry into the grouting pipe 1201, and finally sprays out from the nozzles 1203.

[0045] In some embodiments of this embodiment, in order to spray the slurry better, the positioning block 8 is used to support the grouting pipe 1201. In combination with Figure 1 As shown in the figure, the positioning block 8 is a metal disc. The bottom of the positioning block 8 is fixedly welded to the intersection of the longitudinal steel wire 5 and the transverse steel wire 6. Four positioning blocks 8 are installed in each horizontal row of the slope 1. A U-shaped steel bar is installed on the top of the positioning block 8. When spraying the slurry, the grouting pipe 1201 is placed in the U-shaped steel bar, which has a good supporting effect on the grouting pipe 1201.

[0046] Embodiment 2

[0047] This embodiment provides a slope spraying method, which uses the liftable slope laying and net spraying device of Embodiment 1, and further includes the following method.

[0048] As Figures 1 to 7As shown in the figure, first level the slope 1, and excavate a middle platform in the middle section of the slope 1 to divide the entire slope 1 into an upper slope and a lower slope. Then vertically insert the ejector rod 2 into the top of the slope 1, insert the limit rod 4 on the middle platform, insert the insertion rod 3 into the bottom of the slope 1, then tie the top end of the longitudinal steel wire 5 to the extended end of the ejector rod 2, then pass the bottom end of the longitudinal steel wire 5 through the conduit 13 and tie it to the insertion rod 3, and then interweave multiple auxiliary steel wires 7 and multiple transverse steel wires 6 to form a steel wire mesh. The auxiliary steel wires 7 and the transverse steel wires 6 are tightened against each other, and the transverse steel wires 6 are fixedly tied to the longitudinal steel wires 5. Weld the positioning block 8 at the intersection of the auxiliary steel wire 7 or the longitudinal steel wire 5 and the transverse steel wire 6. The woven steel wire mesh is respectively arranged on the upper and lower slopes of the slope 1. Then lay the mesh cloth 9 under the steel wire mesh, and then fixedly tie the steel wire mesh together with the mesh cloth 9 to the longitudinal steel wire 5 using cable ties. Before grouting, set baffles at the bottom and both sides of the slope 1, and then first grout the lower slope of the slope 1. Sleeve the casing 1001 outside the ejector rod 2, then use the first arc-shaped clamp 1107 and the second arc-shaped clamp 1108 to clamp the grouting pipe 1201, and then horizontally place the grouting pipe 1201 on the lowermost row of positioning blocks 8. When horizontally placing the grouting pipe 1201, make the nozzle 1203 extend into the grouting hole, and then send the concrete slurry into the grouting pipe 1201 through a delivery pump. Then the concrete slurry is sprayed between the slope 1 and the mesh cloth 9 through the nozzle 1203, and the concrete slurry is ejected through the grouting pipe 1201 to form the bottommost base. After the bottommost base solidifies, start the second reduction motor 1103 to drive the spraying component 12 to rise. Then start the first reduction motor 1008, and the wire reel 1012 rotates to wind up the rope 1013, driving the spraying component 12 to move up a certain distance through the slider 1014. Then start the second reduction motor 1103 to drive the spraying component 12 to descend, so that the grouting pipe 1201 can be placed on the upper row of positioning blocks 8 and eject the concrete slurry to form the second layer of base. Then keep repeating, and the concrete base accumulates continuously until the concrete base covers the slope 1.
