Description

Technical Field

[0001] The invention belongs to the technical field of ecological slope protection construction, and specifically relates to a stepped hollow column foot protection flat-laying type ecological slope protection construction device and a construction method thereof. Background Art

[0002] With the acceleration of social modernization and the growth of population, the construction of water conservancy projects has become increasingly important. Ecological slope protection construction not only protects water conservancy projects but also pays attention to the protection of the ecological environment, achieving good results that are both beautiful and safe. In order to make up for the shortcomings of the existing ecological revetment with mesh, many ecological slope protection projects have begun to use prefabricated frame components. The characteristics of prefabricated frame components are firmness, stability and durability. However, there is a problem of difficulty in transportation during the laying process, because the plane length and width of the prefabricated components are relatively large, reaching about one meter. When laying, it is necessary to lay from the top of the slope downward. It is necessary for staff to carry and lay downward, or to use hook-lifting equipment for lifting. It is inconvenient for the equipment to move back and forth, so the investment cost is high but the utility is lacking.

[0003] Therefore, the present application proposes a stepped hollow column foot-protecting flat-paved ecological slope protection construction device and a construction method thereof. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a stepped hollow column foot protection flat-laying ecological slope protection construction device and a construction method thereof.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a step-type hollow column foot-protection flat-laying ecological slope protection construction device and a construction method thereof, comprising two channel steels, both ends of which are respectively erected on the bank protection and the step-type hollow column, and the two channel steels form a rectangular frame;

[0006] An adjustable slideway is provided on the inner side of the rectangular frame for receiving and guiding the improved prefabricated frame member downward;

[0007] The two symmetrical sides of the improved prefabricated frame component are provided with sliding grooves and slidably installed on the adjustable slideway. A plurality of the improved prefabricated frame components are synchronously slidably installed on the adjustable slideway and slide onto the geotextile on the bank protection slope.

[0008] Preferably, the adjustable slide includes a guide slide block and reinforcement ribs welded together, the reinforcement ribs are movably installed in the inner groove of the channel steel and fit into the groove wall, the reinforcement ribs are connected to the external plate through connecting columns extending to the outside of the channel steel, and a through groove is opened on the channel steel for passing the connecting column.

[0009] Preferably, the adjustable slideway is composed of multiple sections, and each section of the adjustable slideway can be connected to form a continuous slideway for sliding the improved prefabricated frame member;

[0010] Each section of the adjustable slideway is independent of each other.

[0011] Preferably, the channel steel is connected to the fixing frame through an adjustable mounting assembly, and the adjustable mounting assembly includes a fixing plate welded to the channel steel, an adjusting plate hinged to the fixing plate, and an adjusting stud fixedly supported between the fixing plate and the adjusting plate for adjusting the level of the adjusting plate.

[0012] Preferably, the fixing frame comprises an L-shaped cantilever fixedly mounted on the adjusting plate, a roller is mounted under the L-shaped cantilever, and the roller is rotatably arranged on the edge of the stepped hollow column.

[0013] Preferably, the stepped hollow column comprises a first step, a second step and a third step, and a perfusion hole is arranged inside the stepped hollow column.

[0014] Preferably, three side surfaces of the first step and the second step, and upper surfaces of the second step and the third step are poured with sandless concrete.

[0015] Preferably, two adjacent sides of the improved prefabricated frame member are provided with protrusions, and the other two sides are provided with grooves capable of cooperating with the protrusions.

[0016] Construction method of stepped hollow column footing flat ecological slope protection:

[0017] Measure and lay out the position line of the stepped hollow column, and use the excavator to vertically press the stepped hollow column into the base bed to form a foot guard;

[0018] After the stepped hollow column is firmly pressed into the base bed, the water in the injection hole is pumped out, and the adsorbent is evenly filled into the injection hole;

[0019] According to the geotechnical design, the cross-section is measured, the embankment is excavated, the foundation surface is leveled, the slope is carefully laid, and the geotextile is laid on the embankment. When laying the geotextile, 100mm needs to be reserved on the top for stacking;

[0020] Measure and place the position line of the prefabricated frame on the geotextile, set up the slope protection construction device according to any one of claims 1 to 3 along the position line, assemble the prefabricated frame therein, slide it down from top to bottom in sequence, align and fit it, and then lower the prefabricated frame from top to bottom onto the slope surface;

[0021] Each row of prefabricated frames is arranged as above, and after sliding down, the slope protection construction device is adjusted so that the grooves and protrusions of the prefabricated frames are aligned and then lowered in sequence.

[0022] Preferably, the inside of the prefabricated frame, between the prefabricated frame and the stepped hollow column, and the corners of the slope are evenly filled with planting materials made locally;

[0023] The adsorbent is activated carbon.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention forms a rectangular slideway through two channel steels, and cooperates with the adjustable slideway installed thereon to guide the improved prefabricated frame component downward, and can guide multiple improved prefabricated frame components downward at the same time, so that each improved prefabricated frame component is positioned adjacent to each other and then lowered onto the slope. The two symmetrical sides of the improved prefabricated frame component are provided with slideways, and the slideways and the adjustable slideways are adapted and engaged thereon, and can descend along the guide slide channel formed by the adjustable slideways. The staff slides the improved prefabricated frame component downward along the adjustable slideway between the two channel steels at the top of the slope, and then opens the adjustable slideways on both sides of the channel steels to release the sliding engagement relationship between the improved prefabricated frame component and the improved prefabricated frame component, and then lowers the improved prefabricated frame component downward. Compared with the hook-hanging equipment, the device is simple to splice and easy to operate, and can directly put the prefabricated component into the correct position. The staff only needs to make adaptive adjustments at the corresponding position, which greatly reduces the pressure and burden of the staff, and the investment cost is low. It has obvious positive benefits.

[0026] By using separate adjustable slides to control the improved prefabricated frame components separately, it is possible to assemble them uniformly on the device and release them separately instead of releasing a row of improved prefabricated frame components downward uniformly, thereby ensuring the controllability of the improved prefabricated frame components when they are removed.

[0027] The prefabricated frame and stepped hollow columns of this method adopt reinforced concrete structure, which is artificial stone with relatively stable chemical properties. It will not corrode or be worn over time and has good durability. The crushed stone and sandy soil taken locally are used as the filling planting materials inside and outside the prefabricated frame, which does not need to be purchased and transported separately. At the same time, it is conducive to the survival and reproduction of amphibians and the rapid growth of vegetation, and is more outstanding in terms of environmental protection.

[0028] This construction method can directly use an excavator to press the stepped hollow column into the lower part of the embankment to form a foot guard. The construction is convenient and the quality is easy to control. At the same time, the improved prefabricated frame components are regular and easy to install, which can reduce manpower and material resources and reduce accidents. The prefabricated frames are connected movably through protrusions and grooves, which have good seismic performance. At the same time, the structure is stable and not easy to deform under load. In addition, the stepped hollow column is embedded in the base bed to form a foot guard, which maximizes the elimination of the impact load of the water flow, improves the stability of the slope protection, and ensures that the slope protection structure is not prone to sliding damage. By setting the sandless concrete on the surface of the stepped hollow column and filling it with adsorbents, on the one hand, the attachment space of microorganisms is increased. The surface of the adsorbent is an aerobic environment and the interior is an anoxic environment. It can promote the attachment and reproduction of different types of microorganisms, improve the diversity of microbial communities, and provide more living space for aquatic animals. On the other hand, it can allow water to enter the column through the gaps between the aggregates of the sandless concrete, and further remove pollutants in the water through the adsorbent in the column, thereby purifying the water quality.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figures 1 to 9 As shown, the present invention provides a stepped hollow column foot protection flat-laying ecological slope protection construction device and a construction method thereof, comprising two channel steels 100, both ends of which are respectively erected on the bank protection and the stepped hollow column 500, and the two channel steels 100 form a rectangular frame;

[0041] An adjustable slideway 200 is provided on the inner side of the rectangular frame for receiving and guiding the improved prefabricated frame member 600 downward;

[0042] Two symmetrical sides of the improved prefabricated frame member 600 are provided with slide grooves 601 which are slidably installed on the adjustable slideway 200. Multiple improved prefabricated frame members 600 are synchronously slidably installed on the adjustable slideway 200 and slide onto the geotextile on the bank protection slope.

[0043] Two channel steels 100 form a rectangular slideway, and the adjustable slideway 200 installed thereon guides the improved prefabricated frame member 600 downwards, and multiple improved prefabricated frame members 600 can be guided downwards at the same time, so that each improved prefabricated frame member 600 is positioned adjacent to each other and then lowered onto the slope. The two symmetrical sides of the improved prefabricated frame member 600 are provided with a slideway 601, and the slideway 601 is adapted to be engaged with the adjustable slideway 200 thereon, and can be lowered along the guide slide channel formed by the adjustable slideway 200. The staff slides the improved prefabricated frame member 600 downwards along the adjustable slideway 200 between the two channel steels 100 at the top of the slope, and then opens the adjustable slideways 200 on both sides of the channel steel 100, releases the sliding engagement relationship between the improved prefabricated frame member 600, and lowers the improved prefabricated frame member 600 downwards.

[0044] The plane size of the improved prefabricated frame component 600 is 1000mm*1000mm, the wall thickness is 50mm, and the height is 500mm. The sliding groove 601 provided thereon has a thickness of 25mm.

[0045] like Figures 4 to 6 As shown, the adjustable slide 200 includes a guide slide block 201 and a reinforcing rib 202 welded together. The reinforcing rib 202 is movably installed in the inner groove of the channel steel 100 and fits with the groove wall. The reinforcing rib 202 is connected to the external plate 204 through a connecting column 203 extending to the outside of the channel steel 100. A through groove 101 is opened on the channel steel 100 for passing the connecting column 203.

[0046] The guide slide block 201 and the reinforcing rib 202 are welded to each other and are located in the groove of the channel steel 100. The superimposed thickness of the guide slide block 201 and the reinforcing ribs 202 on both sides thereof is adapted to the groove. When it extends between the two channel steels 100, it can protrude to the outside of the channel steel 100, forming a slideway that cooperates with the slide groove 601, so that the improved prefabricated frame component 600 can slide on it. At this time, a certain displacement space is left between the guide slide block 201, the reinforcing rib 202 and the inner side of the groove for it to retreat. When the improved prefabricated frame component 600 slides to a specified position on the guide slide block 201, the guide slide block 201 can be withdrawn from the channel steel 100 by pulling the outer plate 204 located on the outside, and the clamping state between the guide slide block 201 and the improved prefabricated frame component 600 is released, and the improved prefabricated frame component 600 falls onto the slope.

[0047] The outer plate 204 has a larger area and is disposed outside the channel steel 100 to be used for limiting the position. The outer plate 204 is pushed until it fits with the channel steel 100 and stops, and the guide slide block 201 is positioned just in place.

[0048] A handle is provided on the outside of the outer plate 204 to facilitate operation by the workers at the construction site. A through slot 101 is provided on the channel steel 100, and the through slot 101 is used to guide the connecting column 203 out from the inside.

[0049] like Figure 6 As shown, the adjustable slideway 200 is composed of multiple sections, and each section of the adjustable slideway 200 can be connected to form a continuous slideway for the improved prefabricated frame member 600 to slide;

[0050] Each section of the adjustable slideway 200 is independent of each other.

[0051] The multiple sections of adjustable slideways 200 together form a continuous channel for the improved prefabricated frame components 600 to slide downward. When a row of improved prefabricated frame components 600 is located on the adjustable slideway 200, they are respectively and simultaneously movably connected to two adjacent guide slide blocks 201. When the previous guide slide block 201 is removed to put down a modified prefabricated frame component 600, the rear improved prefabricated frame component 600 is still connected by another guide slide block 201, and its state is still kept on the adjustable slideway 200 and does not fall. When the other guide slide block 201 is also removed, the currently hung improved prefabricated frame component 600 can be put down.

[0052] When two adjacent improved prefabricated frame components 600 are on the guide slide block 201, the groove and the protrusion are automatically docked during the downward sliding process. Therefore, after being put down, there is also a whole row of neatly docked improved prefabricated frame components 600, which only need to be adjusted with a rubber hammer to be stable and flush.

[0053] like Figures 1 to 3 As shown, the channel steel 100 is connected to the fixing frame 400 through an adjustable mounting assembly 300, and the adjustable mounting assembly 300 includes a fixing plate 301 welded to the channel steel 100, an adjusting plate 302 hinged to the fixing plate 301, and an adjusting stud 303 fixedly supported between the fixing plate 301 and the adjusting plate 302 for adjusting the level of the adjusting plate 302.

[0054] The adjustable mounting assembly 300 is used to adjust its own level with the channel steel 100 on the slope protection with different slopes and then connect the support legs. The adjustable mounting assembly 300 adopts a fixed plate 301 and an adjustment plate 302 to be hinged and used to adjust the angle. The fixed plate 301 is fixedly connected to the channel steel 100 and parallel to it. The adjustment plate 302 is supported upward by adjusting the adjustment studs 303 on the inner side thereof. The top of the adjustment plate 302 is fixedly connected to the fixing frame 400, and the level of the fixing frame 400 is controlled by the adjustment plate 302. This mechanism is suitable for adjusting the adjustment plate 302 to a horizontal state on slopes of various slopes. The adjustment method is simple and the connection is firm and reliable.

[0055] like Figure 2 and Figure 3 As shown, the fixing frame 400 includes an L-shaped cantilever fixedly mounted on the adjustment plate 302 , and a roller 401 is mounted under the L-shaped cantilever, and the roller 401 is rotatably arranged on the edge of the stepped hollow column 500 .

[0056] One end of the L-shaped cantilever is connected to the adjustable mounting assembly 300, and the angle of the adjusting plate 302 is adjusted to make it horizontal. The vertical end of the L-shaped cantilever extends to the outside of the first step of the stepped hollow column 500, and is supported on the side edge of the first step of the stepped hollow column 500 by the roller 401 installed at the bottom of the vertical end. The outer flange on the roller 401 rolls in contact with the outer side of the step of the stepped hollow column 500. Therefore, when the adjustment device is used to construct the next row of improved prefabricated frame components 600, the staff located above the slope protection lifts or props up one end of the device, adjusts the adjustment stud 303 on the adjustable mounting assembly 300 so that the fixed frame 400 remains horizontal after being propped up, and then uses the roller 401 as a support to horizontally move the device to the prefabrication position line of the next row of improved prefabricated frame components 600, puts down the device, and adjusts the adjustment stud 303 to be horizontal.

[0057] A foot support is provided at the lower end of the channel steel 100, and the foot support is located on the inner side of the first step from top to bottom of the stepped hollow column 500, and is used for anti-slip support.

[0058] like Figure 1 and 2 As shown, the stepped hollow column 500 includes a first step, a second step and a third step, and a pouring hole is arranged inside the stepped hollow column 500 .

[0059] The three side surfaces of the first step and the second step, and the upper surfaces of the second step and the third step are poured with sandless concrete.

[0060] The three surfaces are provided with sandless concrete mainly to utilize the gaps between the aggregates of the sandless concrete to allow water to flow through, and then the adsorbent filled in the stepped hollow column 500 can filter the incoming water flow and remove pollutants therein, thereby ensuring the water quality near the foot of the slope and providing a good growth environment for green plants.

[0061] Moreover, the surface of the stepped hollow column can expand the penetration area between the hollow surface and the water flow while maintaining the strength of the entire hollow column. After the stepped hollow column presses down the embankment to become a footing, it can maximize the dissipation of the impact load of the water flow, improve the stability of the slope protection, and ensure that the slope protection structure is not prone to sliding damage.

[0062] like Figure 8 As shown, two adjacent sides of the improved prefabricated frame member 600 are provided with protrusions, and the other two sides are provided with grooves that can cooperate with the protrusions.

[0063] When the improved prefabricated frame components 600 are placed on the adjustable slide 200 and slide down in sequence, two adjacent improved prefabricated frame components 600 on the adjustable slide 200 are connected by the mutual cooperation of the protrusions and the grooves. After the improved prefabricated frame components 600 are lowered from the adjustable slide 200, the prefabricated position lines of a row of improved prefabricated frame components 600 on the geotextile are arranged longitudinally, and then a rubber hammer is used to tap and adjust the position of the improved prefabricated frame components 600 to make them flat and accurate.

[0064] The construction method of the flat ecological slope protection with stepped hollow column footing is to measure and lay out the position line of the stepped hollow column, and use an excavator to vertically press the stepped hollow column into the base bed to form the footing;

[0065] After the stepped hollow column is firmly pressed into the base bed, the water in the injection hole is pumped out, and the adsorbent is evenly filled into the injection hole;

[0066] According to the geotechnical design, the cross-section is measured, the embankment is excavated, the foundation surface is leveled, the slope is carefully laid, and the geotextile is laid on the embankment. When laying the geotextile, 100mm needs to be reserved on the top for stacking;

[0067] Measure and place the position line of the prefabricated frame on the geotextile, set up the slope protection construction device according to any one of claims 1 to 5 along the position line, assemble the prefabricated frame therein, slide it down from top to bottom in sequence, align and fit it, and then lower the prefabricated frame from top to bottom onto the slope surface;

[0068] Each row of prefabricated frames is arranged as above, and after sliding down, the slope protection construction device is adjusted so that the grooves and protrusions of the prefabricated frames are aligned and then lowered in sequence.

[0069] Compared with the traditional green grid ecological slope protection technology, the prefabricated frame and stepped hollow column of this method are prefabricated in the factory, which are not easy to corrode or damage and have outstanding durability. The stepped hollow column is embedded in the base bed to form a foot guard, which can dissipate the kinetic energy of the water body. The prefabricated frames are movably connected by protrusions and grooves, with outstanding seismic performance and guaranteed slope protection quality. At the same time, the stepped hollow column can be pressed into the embankment by an excavator, and the prefabricated frame can be quickly assembled using protrusions and grooves. The construction efficiency is high, the manpower and material resources consumed are less, and the economic benefits are significant.

[0070] This method uses locally sourced gravel and sand as planting materials, providing living and growth space for amphibians and green plants, increasing the green coverage rate of the slope protection structure, and eliminating the tedious operation of transporting fillers. In addition, the interior of the stepped hollow column is filled with adsorbent material and the surface is set with sandless concrete. While purifying river water quality and alleviating soil erosion, the stepped shape adds many interfaces for microorganisms to attach, which has the functions of improving the landscape and perfecting the ecological environment. Therefore, the social and environmental protection benefits are obvious.

[0071] like Fig. 9As shown, the inside of the prefabricated frame, between the prefabricated frame and the stepped hollow column, and the corners of the slope are evenly filled with planting materials made locally;

[0072] The adsorbent is activated carbon.

[0073] By setting sandless concrete on the surface of the stepped hollow column and filling the adsorbent inside it, on the one hand, the attachment space of microorganisms is increased, the surface of the adsorbent material is an aerobic environment, and the inside is an anaerobic environment, which can promote the attachment and reproduction of different types of microorganisms, improve the diversity of microbial communities, and provide more living space for aquatic animals. On the other hand, water can flow into the column through the gaps between the aggregates of the sandless concrete, and further remove pollutants in the water through the adsorbent in the column, thereby purifying the water quality.

[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
