Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slope protection construction. More particularly, the present application relates to a cast-in-place concrete slope protection plate construction process. BACKGROUND

[0002] Slope protection is an important form of dam protection engineering and an important structure for protecting the foundation and preventing water and soil loss. Currently, the measures used in construction include: in-situ prefabrication and on-site assembly of prefabricated plate slope protection, mortar masonry stone slope protection, and cast-in-place concrete plate slope protection. Among them, cast-in-place concrete plate slope protection has strong adaptability, raw materials are easy to purchase, quality is easy to control, work efficiency is high, construction period is short, cost is low, and is widely used.

[0003] In the cast-in-place concrete plate slope protection, slope protection plate formwork is needed. In the patent with application number 202321751761.1, a water conservancy cast-in-place concrete slope protection construction formwork is disclosed. Through the design of support plate one, support plate two, base, baffle, cover plate, sliding block, sliding rail, traction rope, traction motor, and scraping and drawing flower plate, the construction formwork can use the motor to pull the cover plate to replace the workers to complete the scraping and drawing work on the upper surface of the concrete, effectively reducing the labor intensity of the workers and improving the work efficiency. However, there is a gap between the lower side wall of the formwork and the slope surface. When pouring the cast-in-place concrete into the formwork, the cast-in-place concrete is easy to overflow to the outside through the gap, affecting the slope protection construction effect and causing waste of concrete. In addition, when using the above-mentioned cast-in-place concrete slope protection construction formwork for construction, due to the interval of the support plate one or the support plate two, a gap with the width of the support plate one or the support plate two is left between the later poured slope protection plate and the earlier poured slope protection plate, and the gap needs to be filled again, which has poor construction continuity.

[0046] Step four, divide the construction range of each cast-in-place concrete slope protection plate on the slope according to the width of the formwork of the cast-in-place concrete slope protection plate;

[0047] Step five, support the formwork of the cast-in-place concrete slope protection plate on the slope (as shown in Figure 1 The formwork of the cast-in-place concrete slope protection plate comprises a first support plate 1, a second support plate 2 and a first blocking plate 3, a first cover plate 4 is arranged between the first support plate 1 and the second support plate 2, and the first blocking plate 3 is detachably connected to the lower ends of the first support plate 1 and the second support plate 2 at both ends to form a U-shaped structure on the slope; rubber sheets 5 are attached to the lower edges of the outer side walls of the first support plate 1, the second support plate 2 and the first blocking plate 3, the rubber sheets 5 extend to the bottom surfaces of the components to adhere to the slope, and compression assemblies are arranged on the outer side walls of the first support plate 1, the second support plate 2 and the first blocking plate 3, the compression assemblies comprise ear plates 6 connected to the outer side walls of the first support plate 1, the second support plate 2 and / or the first blocking plate 3, the ear plates 6 are parallel to the bottom surfaces of the first support plate 1, the second support plate 2 and / or the first blocking plate 3, threaded holes are formed in the ear plates 6, and bolts 7 are arranged in the threaded holes;

[0048] Step six, turn the rubber sheets 5 outward to adhere to the slope, rotate the bolts 7 to make the lower ends of the bolts 7 close to the slope, and gradually compress the rubber sheets 5 by the driving of the compression plates 8, so that the rubber sheets 5 adhere to the slope under the action of the compression plates 8;

[0049] Step seven, fix the pre-bound steel mesh of the cast-in-place concrete slope protection plate on the inner side of the U-shaped structure, and insert anchor rods into the slope body, and then pour concrete in the inner side of the U-shaped structure;

[0050] Step eight, the first cover plate 4 is translated from the lower end to the upper end of the U-shaped structure, so that the first cover plate 4 can iron the concrete surface, when the first cast-in-place concrete slope protection plate is initial set, the cast-in-place concrete slope protection plate formwork is removed;

[0051] Step nine, the formwork of the later cast-in-place concrete slope protection plate is set beside the previously cast-in-place concrete slope protection plate (as shown in Figure 2 The formwork of the later cast-in-place concrete slope protection plate includes the first support plate 1 and the second stop plate 18, the two ends of the second stop plate 18 are respectively detachably connected to the first support plate 1 and the lower end of the previously cast-in-place concrete slope protection plate, so as to form a U-shaped structure on the slope surface, and the second stop plate 18 is also provided with the rubber sheet 5 and the pressing assembly;

[0052] Step ten, steps six to seven are repeated to complete the concrete pouring of the later cast-in-place concrete slope protection plate, a second cover plate 19 is used to iron the concrete surface in the formwork of the later cast-in-place concrete slope protection plate, when the concrete of the later cast-in-place concrete slope protection plate is initial set, the formwork is removed;

[0053] Step eleven, steps nine to ten are repeated to complete the concrete pouring construction in the total construction range of the cast-in-place concrete slope protection plate, and the bottom sealing concrete is poured in the groove 24 at the slope foot of the total construction range of the cast-in-place concrete slope protection plate, and the poured cast-in-place concrete slope protection plate is maintained.

[0054] Here, the side wall of the first support plate 1, the second support plate 2 and the first stop plate 3 in contact with the concrete is called the inner side wall, the outer side wall of the first support plate 1, the second support plate 2 and the first stop plate 3 refers to the side wall opposite to the inner side wall of each of the first support plate 1, the second support plate 2 and the first stop plate 3, and the bottom surface of the first support plate 1, the second support plate 2 and the first stop plate 3 refers to the surface of each of the first support plate 1, the second support plate 2 and the first stop plate 3 in contact with the slope surface when the first support plate 1, the second support plate 2 and the first stop plate 3 are assembled into a U-shaped structure on the slope surface. The upper end of the cast-in-place concrete slope protection plate refers to the upper end surface of the cast-in-place concrete slope protection plate perpendicular to the slope surface, the lower end of the cast-in-place concrete slope protection plate refers to the lower end surface of the cast-in-place concrete slope protection plate perpendicular to the slope surface, the bottom surface of the cast-in-place concrete slope protection plate refers to the lower plate surface of the cast-in-place concrete slope protection plate in contact with the slope surface, and the top surface of the cast-in-place concrete slope protection plate refers to the upper plate surface parallel to the lower plate surface thereof.

[0055] Here, the lower end of the first support plate 1 and the second support plate 2 refers to the end of the first support plate 1 and the second support plate 2 respectively connected to the first stop plate 3 when the first support plate 1, the second support plate 2 and the first stop plate 3 are assembled into a U-shaped structure on the slope surface;

[0056] Here, screws can be provided at the lower ends of the first support plate 1 and the second support plate 2, and both ends of the first baffle plate 3 can be provided in the through holes corresponding to the screws. The two ends of the first baffle plate 3 are respectively passed through the screws at the lower ends of the first support plate 1 and the second support plate 2, and then locked with nuts, so that the baffle plate can be detachably connected to the lower ends of the first support plate 1 and the second support plate 2;

[0057] Here, the connection method between the first cover plate 4 and the first support plate 1 and the second support plate 2 can be the connection method in the prior art, or the connection method described in the following embodiments. The first cover plate 4 is mainly used to smooth the concrete poured in the U-shaped structure.

[0058] During the aforementioned construction process, the rubber sheet 5 and the compression assembly are used in conjunction to ensure that the rubber sheet 5 adheres tightly to the slope surface. Therefore, when pouring concrete into the cast-in-place concrete slope protection board formwork, concrete slurry is minimized from seeping along the bottom of the U-shaped structure formed by the cast-in-place concrete slope protection board formwork, thereby reducing concrete waste. Furthermore, the first support plate 1, second baffle plate 18, and second cover plate 19 of the cast-in-place concrete slope protection board formwork can be reused, reducing formwork production costs.

[0059] In the prior art, the first cover plate 4 is driven by a motor through a pull rope, but it is not convenient to set up a power supply on the slope protection construction site. The present application also provides a structure that can manually drive the first cover plate 4 to move horizontally.

[0060] like Figures 4-5 As shown, in another embodiment, the interior of the first support plate 1 is hollow, and a screw rod 11 is rotatably connected to the first support plate 1 along the length direction. Here, a second bearing 12 can be provided on the inner wall of the lower end of the first support plate 1, and the lower end of the screw rod 11 can be fixed to the center of the second bearing 12. The upper end of the screw rod 11 passes through the upper end of the first support plate 1 and is connected to a handwheel 16. Here, a circular hole for passing the screw rod 11 is opened at the upper end of the first support plate 1, and a third bearing 13 is provided in the circular hole. The screw rod 11 passes through the center of the third bearing 13 and the third bearing 13 is fixedly connected. A nut 14 is threadedly connected to the part of the screw rod 11 inside the first support plate 1, and a first support rod 15 is connected to the nut 14. A first strip hole is opened on the top surface of the first support plate 1 along the length direction, and the first support rod 15 passes through the first strip hole and extends to the outside of the first support plate 1;

[0061] The second support plate 2 is hollow inside, and a polished rod is connected to the inside of the second support plate 2 along the length direction. A slider is slidably sleeved on the polished rod, and the slider is connected to the second support rod. A second strip-shaped hole is opened on the top surface of the second support plate 2 along the length direction, and the second support rod extends through the second strip-shaped hole to the outside of the second support plate 2;

[0062] The first cover plate 4 is provided with a first plugging hole corresponding to the first support rod 15 and a second plugging hole corresponding to the second support rod at both ends.

[0063] When using the above embodiment, construction workers only need to turn the handwheel 16 to drive the screw 11 to rotate. Due to the limitation of the first support rod 15, the nut 14 and the first support rod 15 can move along the first strip hole, thereby driving the first cover plate 4 to move above the first support plate 1. The first cover plate 4 then drives the second support rod and the slider to move. Due to the limitation of the second support rod, the first cover plate 4 can be placed horizontally between the first support plate 1 and the second support plate 2, so that the lower surface of the first cover plate 4 can smooth the concrete poured in the U-shaped structure. At the same time, because the first cover plate 4 is plug-connected to the first support rod 15 and the second support rod, the first cover plate 4 can be easily removed from the first support rod 15 and the second support rod for replacement and maintenance.

[0064] like Figure 2 、 6 As shown, in another embodiment, the formwork of the cast-in-situ concrete slope protection plate poured later in step nine further includes: an upper end plate 20, which is in the shape of ┘, and is arranged between the first support plate 1 and the upper end of the cast-in-situ concrete slope protection plate poured earlier, and a bayonet 21 is provided at one end of the horizontal plate surface of the upper end plate 20, and the width of the bayonet 21 is adapted to the diameter of the screw rod 11, so that the screw rod 11 is clamped in the bayonet 21;

[0065] A first embedded screw is welded to the upper end of the steel mesh, and the first embedded screw extends from the upper end of the cast-in-situ concrete slope protection plate. A first through hole 22 matching the first embedded screw is provided on the other end of the transverse plate surface of the upper end plate 20. The first embedded screw passes through the first through hole 22 and is connected with a nut so that the upper end plate 20 is detachably connected to the upper end of the cast-in-situ concrete slope protection plate that was cast previously.

[0066] The upper end of the vertical plate surface of the upper end plate 20 is higher than the top surface of the cast-in-place concrete slope protection plate. The plate surface shape of the second baffle 18 is the same as that of the upper end plate 20. The vertical plate surface of the upper end plate 20 and the vertical plate surface of the second baffle 18 are connected by a guide rod 23.

[0067] One end of the second cover plate 19 is provided with a third plug hole corresponding to the first support rod 15 in a direction perpendicular to the plate surface, and the other end of the second cover plate 19 is provided with a guide hole corresponding to the guide rod 23 in a direction parallel to the plate surface.

[0068] The process of setting the formwork of the post-poured cast-in-situ concrete slope protection plate is as follows: the first support plate 1 is placed on the slope surface beside the pre-poured cast-in-situ concrete slope protection plate in parallel with one side of the pre-poured cast-in-situ concrete slope protection plate, the second stop plate 18 is placed at the lower end of the first support plate 1 and the pre-poured cast-in-situ concrete slope protection plate, and the two ends of the second stop plate 18 are connected with the lower end of the first support plate 1 and the pre-poured cast-in-situ concrete slope protection plate respectively to form a U-shaped structure. The lower end of the guide rod 23 is connected to the second stop plate 18, and a blind hole for receiving the guide rod 23 can be provided on the second stop plate 18, the lower end of the guide rod 23 is inserted into the blind hole, so that the second stop plate 18 supports one end of the guide rod 23. Then the guide hole of the second cover plate 19 is aligned with the guide rod 23, the guide rod 23 passes through the guide hole, the second cover plate 19 is slid to align the third insertion hole with the first support rod 15, and then the first support rod 15 passes through the third insertion hole, so that the installation of the second cover plate 19 is completed. Finally, the socket 21 at one end of the upper end plate 20 is clamped on the outer periphery of the lead screw 11, the other end of the upper end plate 20 is connected to the upper end of the pre-poured cast-in-situ concrete slope protection plate, and the upper end of the upper end plate 20 is fixed by connecting the upper end of the guide rod 23 to the upper end plate 20, and the upper end of the upper end plate 20 is fixed. A blind hole for receiving the guide rod 23 can also be provided on the upper end plate 20.

[0069] After the formwork of the post-poured cast-in-situ concrete slope protection plate is set, the concrete can be poured in the range of the formwork. After the pouring of the concrete is completed, the operator only needs to rotate the hand wheel 16 to drive the lead screw 11 to rotate, and due to the limiting of the first support rod 15, the nut 14 on the lead screw 11 and the first support rod 15 can move along the first slot, thereby driving the second cover plate 19 to move above the first support plate 1, and due to the limiting of the guide rod 23, the second cover plate 19 can be horizontally arranged between the first support plate 1 and the side wall of the pre-poured cast-in-situ concrete slope protection plate, so that the lower surface of the second cover plate 19 can smooth the concrete poured in the range of the formwork.

[0070] In another embodiment, a second embedded screw is welded to the lower end of the steel mesh, the second embedded screw extends from the lower end of the cast-in-situ concrete slope protection plate, the surface of the second stop plate 18 is provided with a second through hole matched with the second embedded screw, and after the second embedded screw passes through the second through hole, a nut is connected with the second embedded screw to detachably connect one end of the second stop plate 18 with the lower end of the pre-poured cast-in-situ concrete slope protection plate. In this embodiment, a specific implementation manner of detachable connection between the second stop plate 18 and the lower end of the pre-poured cast-in-situ concrete slope protection plate is provided. As can be seen from the above implementation manner, the second stop plate 18 is easy to disassemble and assemble, which is convenient for construction. The connection manner of the second stop plate 18 and the first support plate 1 can refer to the connection manner of the first stop plate 3 and the first support plate 1.

[0072] Specifically, the surface of the fixing rod 10 can also be provided with barbs, so that the connection between the fixing rod 10 and the slope body is more firm after the fixing rod 10 is inserted into the slope body.

[0073] In the above embodiment, the bottom surface of the first support plate 1 and / or the second support plate 2 and / or the first baffle plate 3 and / or the second baffle plate 18 is provided with a fixing rod 10, which is inserted into the slope body to make the connection between the first support plate 1 and / or the second support plate 2 and / or the first baffle plate 3 and / or the second baffle plate 18 and the slope body more firm, and better provide a counterforce for the bolt 7, so that the pressing plate 8 can more firmly press the rubber sheet 5.

[0074] As shown in another embodiment, Figure 3 the top surface of the pressing plate 8 is provided with a first bearing 9, and the lower end of the bolt 7 is fixed at the center of the first bearing 9 to be rotationally connected with the pressing plate 8. The first bearing 9 connects the pressing plate 8 and the bolt 7, so that the bolt 7 rotates without rotating the pressing plate 8, but only lifts or lowers the pressing plate 8.

[0075] In another embodiment, the lower surface of the first cover plate 4 is provided with a first flattening plate 17 with a width adapted to the distance between the first support plate 1 and the second support plate 2, and the lower surface of the second cover plate 19 is provided with a second flattening plate 25 with a width adapted to the distance between the first support plate 1 and the cast-in-place concrete slope protection plate.

[0076] Because during construction, when there is a thinner requirement for the thickness of the concrete, the first flattening plate 17 in the above embodiment protrudes between the first support plate 1 and the second support plate 2, and the second flattening plate 25 protrudes between the first support plate 1 and the cast-in-place concrete slope protection plate, so the excess concrete on the surface can be scraped off to achieve the thinning requirement.

[0077] As shown in another embodiment, Figure 5 , 7 the top surface of the first support plate 1 and the second support plate 2 is coated with a wear-resistant and drag-reducing coating. Because the first cover plate 4 is inserted with the first support rod 15 and the second support rod, and part of the surface of the first cover plate 4 also contacts the top surface of the first support plate 1 and the second support plate 2, the first cover plate 4 will rub against the first support plate 1 and the second support plate 2 during movement. Here, the wear-resistant and drag-reducing coating can reduce friction, facilitate the movement of the first cover plate 4, and reduce the wear of the first cover plate 4, the first support rod 15, and the second support rod.

[0078] In another embodiment, asFigure 8 As shown, the reinforcement mesh is tied with a drain pipe 26, when the cast-in-place concrete slope protection plate solidifies, the outlet of the drain pipe 26 is flush with the top surface of the cast-in-place concrete slope protection plate, specifically, when the reinforcement mesh is fixed along the slope surface, the drain pipe 26 is in a horizontal state or slightly downwardly inclined state, the outlet end of the drain pipe 26 is cut into a bevel which is flush with the top surface of the cast-in-place concrete slope protection plate, the pre-embedded drain pipe can drain the accumulated water in the slope body, so as to avoid that the slope body contains too much water and causes slope instability.

[0079] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, it can be fully applied to various fields suitable for the present application, and additional modifications can be easily realized by those skilled in the art, therefore, the present application is not limited to specific details and the figures shown and described herein, without departing from the general concept defined by the claims and the equivalent scope.
