Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically, to a modular detachable temporary slope building drainage layer structure and construction method. Background Art

[0002] In various engineering construction projects, temporary slope building is one of the common construction measures. For example, in engineering scenarios such as road widening, foundation pit excavation, and site leveling, in order to meet the needs of construction machinery passage, material stacking, and earthwork balance, it is often necessary to construct temporary slopes. However, traditional temporary slope building has many deficiencies in dealing with drainage problems, which not only affect the construction progress and quality, but may also pose safety hazards and increase project costs.

[0003] Traditional temporary slope building drainage usually relies on simple methods such as simply laying a sand and gravel layer or geotextile on the slope surface. Although the sand and gravel layer has certain water permeability, the drainage efficiency is limited, and under long-term rainfall or a large amount of water flow scouring, the sand and gravel are easily washed away, resulting in the failure of the drainage function and threatening the slope stability. Although geotextile can play a certain role in filtration and drainage, its laying process is complex, with high construction requirements, and it is easily damaged in complex terrains and harsh construction environments, making it difficult to maintain effective drainage performance for a long time.

[0004] In the patent with the patent name: Soft structure slope drainage device for slope construction maintenance, and the publication number: CN113123425B, it is proposed that during slope construction, especially for working conditions with large surface runoff and a high water source, the surface drainage function of the slope must be considered during the construction process. The traditional method is to pump water and drain it from high to low through a water pump and a drainage pipe. However, this method has a large dependence on electricity, and the drainage efficiency is not as good as that of a drainage ditch, and it requires personnel to take care of it. And it can be directly adjusted and connected according to the on-site terrain conditions, and it can be decided whether to excavate and set a groove according to the project needs. It can be used for both permanent slope drainage structures and short-term slope drainage, and its structure can be recycled and reused; when in use in this scheme, when water flows through, the self-pressure of the water generates a component force that prevents the guide plate from tilting inward, and at the same time, the water flow makes the gravity plate stable under the action of water gravity and water pressure, playing a self-stabilizing role to prevent the drainage unit from collapsing or tilting. However, the flexible plate used to carry the water flow in the middle is inserted through sealing nails, forming a destructive plug-in fixation. Once the water flow is too large or the flexible plate is pulled, it is extremely easy to cause damage to the flexible plate, and its destructive plug-in fixation also requires manual tightening and other fixation actions. Once a certain position is not fixed well, it is extremely easy to cause the flexible plate to come off. Therefore, a modular detachable temporary slope building drainage layer structure and construction method are proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a modular detachable temporary slope building drainage layer structure and a construction method thereof to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: A modular detachable temporary slope building drainage layer structure, including a first L-shaped support plate and a second L-shaped support plate. The first L-shaped support plate and the second L-shaped support plate are L-shaped and arranged opposite to each other. The L-shaped right-angle positions of the first L-shaped support plate and the second L-shaped support plate are arc-shaped. Damping rotating shafts are installed on both the first L-shaped support plate and the second L-shaped support plate. A magnetic soft plate is hinged to the outside of the damping rotating shaft. A water guiding soft plate is clamped between the two magnetic soft plates and the first L-shaped support plate and the second L-shaped support plate. A magnetic attraction component is installed inside the first L-shaped support plate; The magnetic attraction component includes a magnet block integrally formed inside the first L-shaped support plate. The magnet block is located at the arc-shaped position of the first L-shaped support plate and the second L-shaped support plate. The magnet block is used to generate adsorption on the magnetic soft plate, and the water guiding soft plate is clamped by adsorbing the magnetic soft plate. Multiple second L-shaped support plates, first L-shaped support plates and water guiding soft plates form a temporary drainage layer.

[0007] Preferably, sliding grooves are opened inside both the first L-shaped support plate and the second L-shaped support plate. An extension plate is slidably connected inside the sliding groove. A floating plate is hinged to the outside of the extension plate. The floating plate is hollow.

[0008] Preferably, insertion holes are opened on the outside of the floating plates located on the first L-shaped support plate and the second L-shaped support plate. Multiple insertion rods are integrally formed on the outside of the floating plates located on the second L-shaped support plate. The insertion rods are used to be inserted into the inside of the insertion holes to form a connected shielding shed between two adjacent floating plates.

[0009] Preferably, clamping grooves are opened on the outside of both the first L-shaped support plate and the second L-shaped support plate. When water flows through the outside of the magnetic soft plate, the flowing water pressure will push the magnetic soft plate and the water guiding soft plate to be extruded into the clamping groove. After being extruded, the magnetic soft plate and the water guiding soft plate generate outward convex deformation and are clamped into the inside of the clamping groove to form extrusion clamping.

[0010] Preferably, inclined water guiding parts are opened on both sides of the floating plate. The inclined water guiding parts are used to provide guidance for the water flow when the water flow passes through, and guide the water flow passing through the inclined water guiding parts to the lower part of the floating plate, so that the water flow enters between the floating plate and the magnetic soft plate for flowing.

[0011] Preferably, the floating plate is composed of a plurality of rubber connecting plates and hollow floating boxes adhered to each other.

[0012] Preferably, a plurality of metal shaping flexible rods are integrally formed inside the magnetic adsorption flexible board.

[0013] Preferably, a plurality of threaded holes are formed outside the first L-shaped support plate, threaded rods are threadedly connected inside the threaded holes, hinge seats are fixedly connected to the outside of the threaded rods, and support rods are hinged inside the hinge seats.

[0014] Preferably, a connecting rope is wound around the inside of the insertion holes formed outside the two floating boards on the adjacent side.

[0015] The present invention also provides a modular detachable temporary slope construction drainage layer construction method, including the following steps: S1. Dig a placement pit of -cm at the position where the temporary slope needs to be built, place a plurality of first L-shaped support plates and second L-shaped support plates relatively in the pit according to the size requirements of the temporary slope, and splice the plurality of first L-shaped support plates and second L-shaped support plates into the temporary slope drainage channels on both sides; S2. Clamp the two sides of the water guiding flexible board between the first L-shaped support plate and the magnetic adsorption flexible board and between the second L-shaped support plate and the magnetic adsorption flexible board respectively to form a bottom drainage channel; S3. Insert the extension plate into the sliding groove, and adjust the floating board to fit against the outside of the magnetic adsorption flexible board to form a channel shield.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, the whole water guiding flexible board is clamped and connected by the first L-shaped support plate, the second L-shaped support plate and the magnetic adsorption flexible board, so that it is more convenient for the staff to disassemble and install when installing the temporary slope construction drainage layer structure. The modular installation is more convenient. And when fixing the water guiding flexible board, magnetic adsorption is used, which can ensure that when it is convenient to disassemble and install, the external pressure on the forced pulling force of the water guiding flexible board can be reduced, and the phenomenon that the water guiding flexible board is damaged due to strong stress can be reduced.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1. As Figure 1 shown, a modular detachable temporary slope drainage layer structure of the present application includes a first L-shaped support plate 100 and a second L-shaped support plate 101. The first L-shaped support plate 100 and the second L-shaped support plate 101 are L-shaped and arranged opposite to each other. The L-shaped right-angle positions of the first L-shaped support plate 100 and the second L-shaped support plate 101 are arc-shaped. Damping rotating shafts 102 are installed on both the first L-shaped support plate 100 and the second L-shaped support plate 101. A magnetic attraction soft plate 103 is hinged to the outside of the damping rotating shaft 102. A water guiding soft plate 105 is clamped between the two magnetic attraction soft plates 103 and the first L-shaped support plate 100 and the second L-shaped support plate 101. A magnetic attraction component is installed inside the first L-shaped support plate 100; The magnetic attraction component includes a magnet block 104 integrally formed inside the first L-shaped support plate 100. The magnet block 104 is located at the arc-shaped positions of the first L-shaped support plate 100 and the second L-shaped support plate 101. The magnet block 104 is used to generate adsorption on the magnetic attraction soft plate 103, and the water guiding soft plate 105 is clamped by adsorbing the magnetic attraction soft plate 103. Multiple second L-shaped support plates 101, first L-shaped support plates 100, and water guiding soft plates 105 form a temporary drainage layer.

[0021] Specifically, during the use process, the staff places multiple first L-shaped support plates 100 and multiple second L-shaped support plates 101 opposite to each other, and arranges the first L-shaped support plates 100 and the second L-shaped support plates 101 in a long strip shape to form a drainage channel. Before placing the first L-shaped support plates 100 and the second L-shaped support plates 101, a 10-20 cm pit needs to be dug at the position where the drainage channel is installed, so as to place the first L-shaped support plates 100 and the second L-shaped support plates 101 inside the pit, which can ensure the stability of the drainage channel.

[0022] Further, after the continuous first L-shaped support plates 100 and second L-shaped support plates 101 on both sides are placed, the staff lifts the magnetic soft plate 103 located on the first L-shaped support plates 100 and the second L-shaped support plates 101 upwards. After lifting, the soft water guide soft plate 105 is placed under the magnetic soft plate 103, and both sides of the water guide soft plate 105 are clamped through the connections between the first L-shaped support plate 100 and the magnetic soft plate 103 and between the second L-shaped support plate 101 and the magnetic soft plate 103. After the clamping is completed, when the magnetic soft plate 103 approaches the first L-shaped support plate 100 and the second L-shaped support plate 101, it will be attracted by the magnet block 104. When the magnet block 104 attracts the magnetic soft plate 103 to form magnetic adsorption, the water guide soft plate 105 can be tightly clamped and adsorbed. In the case of being clamped and adsorbed, the phenomenon that the water guide soft plate 105 is separated from the second L-shaped support plate 101 and the first L-shaped support plate 100 is avoided. The overall installation is convenient, and when disassembling, only the magnetic soft plate 103 needs to be opened and the water guide soft plate 105 can be removed.

[0023] Further, the surface of the water guide soft plate 105 is a rough surface, and the sides of the first L-shaped support plate 100, the second L-shaped support plate 101, and the magnetic soft plate 103 close to the water guide soft plate 105 are also rough surfaces, which can increase a certain amount of friction when clamping the water guide soft plate 105 and avoid the separation phenomenon.

[0024] As Figures 1 - 3 shown, a plurality of threaded holes 800 are opened on the outside of the first L-shaped support plate 100. A threaded rod 803 is threadedly connected inside the threaded hole 800. An articulated seat 801 is fixedly connected to the outside of the threaded rod 803. A support rod 802 is articulated inside the articulated seat 801.

[0025] Specifically, when installing the temporary drainage layer, the threaded rod 803 can also be threadedly connected into the internal thread hole 800, so that a connection is formed between the hinge seat 801 and the first L-shaped support plate 100 or the magnetic soft plate 103. In the case of forming a connection, the support rod 802 can be adjusted to directly contact the ground, so as to further support the first L-shaped support plate 100 and the second L-shaped support plate 101, and increase the overall stability.

[0026] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: Compared with the prior art, in this embodiment, the water guide soft plate 105 is clamped and connected by the first L-shaped support plate 100, the second L-shaped support plate 101 and the magnetic soft plate 103 as a whole, so that it is more convenient for the staff to disassemble and install when installing the temporary slope drainage layer structure. The modular installation is more convenient. And when fixing the water guide soft plate 105, magnetic adsorption is used, which ensures that when it is convenient to disassemble and install, the external pressure on the water guide soft plate 105 can be reduced, and the forced pulling force on the water guide soft plate 105 can be reduced, and the phenomenon that the water guide soft plate 105 is damaged due to strong stress can be reduced.

[0027] Furthermore, a plurality of metal shaping soft rods 700 are integrally formed inside the magnetic soft plate 103. The metal shaping soft rods 700 can increase the overall support of the magnetic soft plate 103, and the plurality of metal shaping soft rods 700 inside the magnetic soft plate 103 can increase the adsorption strength of the magnet block 104 on the magnetic soft plate 103, and at the same time ensure the support and shaping performance of the magnetic soft plate 103.

[0028] Embodiment 2. Considering that during the use process, the temporary slope drainage layer structure is not installed and disassembled on the same day when it is used. Sometimes, the temporary slope drainage layer structure needs to be continuously used throughout the construction period. After the temporarily used temporary slope drainage layer structure is installed, external fallen leaves or other impurities are likely to fall into the drainage channel. Once the fallen leaves and other impurities accumulate too much, it is easy to cause the blockage of the drainage channel. To solve the above technical problems, the present application proposes the following technical solutions: As Figures 3 - 4 shown, sliding grooves are opened inside the first L-shaped support plate 100 and the second L-shaped support plate 101. An extension plate 200 is slidably connected inside the sliding grooves. A floating plate 201 is hinged to the outside of the extension plate 200. The floating plate 201 is hollow.

[0029] Specifically, during use, when debris such as fallen leaves enters the interior of the channel, it will cause partial blockage inside the channel. When water flows into the interior of the channel, the large amount of water flowing in will cause the floating plate 201 to float. When the floating plate 201 floats, the water can pass through the bottom of the floating plate 201, while the debris remains on the floating plate 201, making the drainage channel unobstructed as a whole and avoiding the situation where the debris directly blocks the channel and causes the water to be unable to drain directly.

[0030] As Figure 4 shown, inclined water guiding parts 500 are provided on both sides of the floating plate 201. The inclined water guiding parts 500 are used to provide guidance to the water flow when the water flow passes through, and guide the water flow passing through the inclined water guiding parts 500 to the lower part of the floating plate 201, so that the water flow enters between the floating plate 201 and the magnetic soft plate 103 and flows.

[0031] Specifically, through the setting of the inclined water guiding parts 500, after the water flow enters the drainage groove formed by the first L-shaped support plate 100 and the second L-shaped support plate 101, when the water flow contacts the inclined water guiding parts 500, the inclined water guiding parts 500 form guidance for the water flow. The water flow guided by the inclined water guiding parts 500 will gradually flow into the lower part of the floating plate 201, so that the water flow flows between the floating plate 201 and the magnetic soft plate 103, and when the water flow enters between the floating plate 201 and the magnetic soft plate 103, the entire floating plate 201 will float, thereby pushing up the debris accumulated on the floating plate 201 together and reducing the blockage phenomenon.

[0032] Furthermore, when the water flow gradually increases, after the magnetic soft plate 103 floats up, it will also drive the extension plate 200 to slide upward in the sliding groove. After the extension plate 200 slides upward, it can expand the overall height of the first L-shaped support plate 100 and the second L-shaped support plate 101, expand the water flow carrying capacity, and avoid the phenomenon of water overflow caused by too much water flow.

[0033] The technical solutions in the embodiments of the present application above have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, through the setting of the floating plate 201, a debris shield can be formed inside the flow groove formed by the first L-shaped support plate 100 and the second L-shaped support plate 101. Thus, when debris falls into the flow groove formed by the second L-shaped support plate 101 and the first L-shaped support plate 100, the buoyancy of the water flow is used to cooperate with the floating plate 201 to lift the debris, so as to form a flow channel between the floating plate 201, the second L-shaped support plate 101 and the first L-shaped support plate 100, and avoid the phenomenon that the flow groove is blocked due to debris accumulation.

[0034] Embodiment 3: Considering that during the construction process, a large amount of dirt and other sundries often fall into the flow channel formed by the first L-shaped support plate 100 and the second L-shaped support plate 101. Once a large amount of heavier sundries fall onto the floating plate 201, the floating plate 201 cannot float up to form an additional flow channel. To solve the above technical problems, the present application proposes the following technical solutions, specifically: As Figure 1 shown, insertion holes 300 are provided on the outside of the floating plates 201 located on the first L-shaped support plate 100 and the second L-shaped support plate 101. A plurality of insertion rods 302 are integrally formed on the outside of the floating plate 201 located on the second L-shaped support plate 101. The insertion rods 302 are used to be inserted into the inside of the insertion holes 300 to form a connected shielding shed between two adjacent floating plates 201.

[0035] Specifically, when there are too many heavier sundries outside the first L-shaped support plate 100 and the second L-shaped support plate 101 that may fall into the flow channel formed by the first L-shaped support plate 100 and the second L-shaped support plate 101, the two opposite floating plates 201 can be pulled up, and the two floating plates 201 can be overlapped with each other through the hinge points of the extension plates 200. In the case of mutual overlap, the insertion rods 302 can also be inserted into the inside of the insertion holes 300, so as to connect the two adjacent floating plates 201 to form a shielding shed to prevent too many external sundries from falling into the flow channel.

[0036] As Figure 1 shown, a connecting rope 301 is wound around the inside of the insertion holes 300 provided on the outside of the two adjacent floating plates 201 on one side.

[0037] Specifically, in the case where the adjacent floating plates 201 on one side are connected to each other, the connecting rope 301 can also be wound into the insertion holes 300 between the two floating plates 201, so as to strengthen the connection between the two floating plates 201.

[0038] As Figure 5 shown, the floating plate 201 is composed of a plurality of rubber connecting plates 600 and a hollow floating box 601 adhered to each other.

[0039] Specifically, during the floating process of the floating plate 201, a plurality of rubber connecting plates 600 generate a certain buoyancy when contacting the water flow. Through the arrangement of the rubber connecting plates 600, the overall floating plate 201 has bendable adjustability, which is convenient for the staff to connect the two floating plates 201 to form a shielding shed.

[0040] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, by inserting the insertion rod 302 into the insertion hole 300, the two floating plates 201 are connected to each other. When the two floating plates 201 are connected to each other, a shielding shed can be formed. Under the use of the shielding shed, the situation where external sundries fall into the flow groove can be further reduced, and the accumulation of sundries affecting the drainage capacity of the flow groove can be avoided.

[0041] Embodiment 4. Considering that a large impact force will be generated when the water flow passes through the inside of the flow groove, and once the water guiding soft plate 105 is not well clamped between the first L-shaped support plate 100 and the magnetic attraction soft plate 103, it may cause the entire water guiding soft plate 105 to be misaligned and run out of the clamping phenomenon between the first L-shaped support plate 100, the second L-shaped support plate 101 and the magnetic attraction soft plate 103 under the continuous flow impact of the water flow. For the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically: As Figure 1 shown, clamping grooves 400 are provided on the outsides of the first L-shaped support plate 100 and the second L-shaped support plate 101. When the water flow passes through the outside of the magnetic attraction soft plate 103, the flowing water pressure will push the magnetic attraction soft plate 103 and the water guiding soft plate 105 to be extruded into the clamping groove 400. After being extruded, the magnetic attraction soft plate 103 and the water guiding soft plate 105 generate outward convex deformation and are clamped into the inside of the clamping groove 400 to form extrusion clamping.

[0042] Specifically, during the use process, when the water flow enters the flow groove formed by the second L-shaped support plate 101, the damping rotating shaft 102 and the water guiding soft plate 105, the water flow flows inside the flow groove. When the water flow flows, it will squeeze the connecting rope 301 and the water guiding soft plate 105. When the magnetic attraction soft plate 103 and the water guiding soft plate 105 are squeezed, they will generate deformation. In the case of generating deformation, they can cooperate with the clamping groove 400. In the presence of the clamping groove 400, the deformed magnetic attraction soft plate 103 and the water guiding soft plate 105 will generate outward convex deformation and be clamped into the inside of the clamping groove 400, thereby forming external clamping. In the case of forming external clamping, the stability of the water guiding soft plate 105 between the first L-shaped support plate 100, the second L-shaped support plate 101 and the magnetic attraction soft plate 103 can be further ensured, and the separation phenomenon of the water guiding soft plate 105 from the second L-shaped support plate 101, the first L-shaped support plate 100 and the magnetic attraction soft plate 103 can be avoided.

[0043] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: In this embodiment, through the setting of the clamping groove 400, when water flows through the magnetic soft plate 103, the magnetic soft plate 103 and the water guiding soft plate 105 can be squeezed. The water pressure formed when water flows through will cause the magnetic soft plate 103 and the water guiding soft plate 105 to deform. The deformed magnetic soft plate 103 and water guiding soft plate 105 will further be clamped into the interior of the clamping groove 400, so as to further ensure the stability of the water guiding soft plate 105 inside the flow groove by forming a clamping connection, and avoid the separation of the water guiding soft plate 105 from the second L-shaped support plate 101, the first L-shaped support plate 100 and the magnetic soft plate 103 during use.

[0044] The present invention also provides a modular detachable temporary slope building drainage layer construction method, including the following steps: S1. Excavate a placement pit 10 - 20 cm deep at the position where the temporary slope needs to be built, and place multiple first L-shaped support plates 100 and second L-shaped support plates 101 relatively in the pit according to the size requirements of the temporary slope, and assemble the multiple first L-shaped support plates 100 and second L-shaped support plates 101 into drainage channels for the two-side temporary slopes; S2. Clamp the two sides of the water guiding soft plate 105 between the first L-shaped support plate 100 and the magnetic soft plate 103 and between the second L-shaped support plate 101 and the magnetic soft plate 103 respectively to form a bottom drainage channel; S3. Insert the extension plate 200 into the sliding groove, and adjust the floating plate 201 to fit the outside of the magnetic soft plate 103 to form a channel shield.

[0045] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
