Description

Technical Field

[0002] With the continuous development of urban infrastructure construction in my country, a large amount of urban construction waste soil is generated during the construction process, and its discharge problem is becoming more and more serious. Landfill is usually used to treat the waste soil. With the gradual accumulation and stacking of the waste soil, a waste soil slope is formed, which is mainly located in and around the city. Once an accident occurs due to instability, it will cause serious loss of life and property and extensive social impact. There are many factors that cause the instability of the waste soil slope. Among them, rainfall and surface water infiltration will increase the moisture content of the waste soil slope, while causing the groundwater level to rise, further reducing the stability of the slope, which is the main factor causing the instability of the slope. Therefore, it is necessary to use a reasonable and fast drainage system to reduce the impact of rainfall and surface water infiltration on the stability of the waste soil slope and avoid the occurrence of instability disasters. However, the current drainage system of the waste soil slope is relatively simple, and it only relies on the gravity drainage system for drainage.

[0047] With the continuous development of urban infrastructure construction in my country, a large amount of urban construction waste soil is generated during the construction process, and its discharge problem is becoming more and more serious. Landfill is usually used to treat the waste soil. With the gradual accumulation and stacking of the waste soil, a waste soil slope is formed, which is mainly located in and around the city. Once an accident occurs due to instability, it will cause serious loss of life and property and extensive social impact. There are many factors that cause the instability of the waste soil slope. Among them, rainfall and surface water infiltration will increase the moisture content of the waste soil slope, while causing the groundwater level to rise, further reducing the stability of the slope, which is the main factor causing the instability of the slope. Therefore, it is necessary to use a reasonable and fast drainage system to reduce the impact of rainfall and surface water infiltration on the stability of the waste soil slope and avoid the occurrence of instability disasters. However, the current drainage system of the waste soil slope is relatively simple, and it only relies on the gravity drainage system for drainage. It does not take into account the large difference in the drainage properties of the upper and lower strata of the waste soil slope, resulting in poor drainage effect when the rainfall is too large.

[0048] In view of this, the present invention provides a stratified drainage system 100 for a slag slope. Figures 1 to 7 This is an embodiment of a stratified drainage system 100 for a slag slope provided by the present invention.

[0049] See also Figures 1 to 5The slope of the muck slope 200 is composed of a vegetation layer 210, a sand landfill layer 220, a clay landfill layer 230 and a stable stratum 240 from top to bottom along its slope height direction. The muck slope layered drainage system 100 includes a drainage channel 1, a surface drainage structure 2 and an underground drainage structure 3. The drainage channel 1 is arranged at the bottom of the muck slope 200, and the bottom of the drainage channel 1 penetrates into the clay landfill layer 230; the surface drainage structure 2 is arranged on the sand landfill layer 220, and includes an intercepting ditch 21, a plurality of drainage ditches and a plurality of inspection walkways 22. The intercepting ditch 21 is arranged at the top of the muck slope 200 and is connected to the drainage channel 1. The plurality of drainage ditches and the plurality of inspection walkways 22 are connected to the drainage channel 1. The inspection walkway 22 is arranged on the slope surface of the slag slope 200 and is arranged in a stepped manner. The multiple drainage ditches are distributed at intervals, and an inspection walkway 22 is arranged between any two adjacent drainage ditches. Each inspection walkway 22 includes a walkway body 221 and multiple water collection channels 222.

[0050] In the technical solution of the present invention, a surface drainage structure 2 is arranged on the sand landfill layer 220 to realize surface drainage, and an underground drainage structure 3 is arranged in the sand landfill layer 220 to realize underground drainage. In this way, by arranging the surface drainage structure 2 and the underground drainage structure 3 in layers, the surface drainage demand and the underground drainage demand can be met at the same time, the drainage efficiency of the slag slope 200 is greatly improved, and the influence of rainfall and rising groundwater level on the stability of the slag slope 200 is reduced; at the same time, the inspection trail 22 includes a trail body 221 and a water collection channel 222, and a pumping device is arranged on the trail body 221. The water collection channel 222 connects two adjacent drainage ditches for completing surface drainage, and the trail body 221 is arranged on the upper side of the water collection channel 222 and is provided with a pumping device, which can not only provide space for staff to walk and check the drainage situation and the greening situation of the slag slope 200, but also provide space for staff to repair the pumping device and other equipment without affecting surface drainage.

[0051] It should be noted that, in the present invention, the water collection well 31 also has a water storage function. The water in the water collection well 31 is pumped out to the vegetation layer 210 through the pumping device to supply water to the vegetation layer 210, thereby realizing the greening of the slag slope 200 and saving water resources. When the rainfall is too large, so that the amount of water is greater than the storage capacity of the water collection well 31, at this time, the water collection well 31 is used for drainage, and the excess water is discharged through the drainage ditch and / or the groundwater pipe 32.

[0052] More specifically, the pumping device includes a water pump, a water inlet pipe and a water outlet pipe. One end of the water inlet pipe extends into the water collection well 31 and the other end is connected to the water pump. One end of the water outlet pipe is connected to the water pump and the other end is arranged toward the vegetation layer 210.

[0053] It should also be noted that, in the present invention, the water in the intercepting ditch 21 flows in three parts, one part of which flows directly from the two ends of the intercepting ditch 21 to the drainage channel 1, another part flows to the drainage channel 1 through the drainage ditch and the water collection channel 222, and the other part seeps into the ground through the drainage ditch and the water collection channel 222, and then flows to the drainage channel 1 through the collection well 31 and the groundwater pipe 32.

[0054] For further information, see Figures 1 to 4 The slope surface includes a plurality of first drainage areas and a plurality of second drainage areas alternately distributed along the longitudinal direction; the plurality of drainage ditches include a plurality of transverse drainage ditches 23 and a plurality of longitudinal drainage ditches 24, each of the first drainage areas is provided with at least one transverse drainage ditch 23, each of the transverse drainage ditches 23 is extended along the transverse direction, and each of the second drainage areas is provided with a plurality of longitudinal drainage ditches 24 distributed along the transverse direction at intervals, each of the longitudinal drainage ditches 24 is extended along the longitudinal direction; the outer periphery of each transverse drainage ditch 23 is provided with a water collection well 31; an inspection walkway 22 is provided between any adjacent transverse drainage ditch 23 and the longitudinal drainage ditch 24; in this way, adjacent transverse drainage ditches 23 and longitudinal drainage ditches 24 are connected through the water collection channel 222, wherein a part of the water flowing from the first drainage area to the second drainage area is used for greening the vegetation layer 210 to save water resources, and the other part flows through the longitudinal drainage ditch 24 to the water collection channel 222, and then flows into the transverse drainage ditch 23 to avoid excessive water seepage in the vegetation layer 210.

[0055] It should be noted that, in the present invention, only one transverse drainage ditch 23 may be provided in each of the first drainage areas, or a plurality of transverse drainage ditch 23 may be provided, and the plurality of transverse drainage ditch 23 are distributed at intervals along the transverse direction.

[0056] For further information, see Figure 1 and Figure 4Each inspection walkway 22 further includes a plurality of support columns 223 and a guardrail 224. The plurality of support columns 223 are arranged at the lower side of the walkway body 221. The plurality of support columns 223 are distributed at intervals in the transverse direction, and are staggered with the plurality of longitudinal drainage ditches 24 arranged on the adjacent second drainage area. The water collection channel 222 is arranged between any two adjacent support columns 223. The guardrail 224 is arranged on one side of the walkway body 221 close to the adjacent transverse drainage ditch 23, and is extended in the transverse direction. In this way, the support columns 223 are used to support the walkway body 221, and avoid the water collection channel 222, so that the water collection channel 222 is connected with the longitudinal drainage ditch 24. The guardrail 224 is arranged to facilitate the workers to carry out work activities on the slope of the slag slope 200, and also to ensure the safety of the workers.

[0057] More specifically, in one embodiment of the present invention, the water collection channel 222 is paved with stacked gravels, which can not only support the main body of the walkway 221, but also allow water to flow through the gaps between the gravels to connect the transverse drainage ditch 23 and the longitudinal drainage ditch 24.

[0058] More specifically, in one embodiment of the present invention, the walkway body 221, the support columns 223 and the guardrails 224 are all made of cement.

[0059] For details, please refer to Figures 1 to 5 Each of the transverse drainage ditches 23 is a prefabricated concrete part, and is sleeved at the wellhead of the corresponding water collection well 31; each of the transverse drainage ditches 23 is provided with a first hanging ring 231. In this way, the transverse drainage ditches 23 can be installed modularly, and the first hanging ring 231 is convenient for installation or removal, thereby facilitating subsequent maintenance and replacement.

[0060] Specifically, in one embodiment of the present invention, the longitudinal drainage ditch 24 is formed by on-site cement casting. In another embodiment of the present invention, the longitudinal drainage ditch 24 is a precast concrete part to achieve modular installation. More specifically, the longitudinal drainage ditch 24 is also provided with a hanging ring.

[0061] Specifically, the inner wall of the transverse drainage ditch 23 and the inner wall of the longitudinal drainage ditch 24 are paved with anti-seepage materials to prevent the inflowing water from penetrating into the sand landfill layer 220 to increase the moisture content of the slope and affect the stability of the slag slope 200 .

[0062] For details, please refer to Figure 4 and Figure 5Each of the water collecting wells 31 is a prefabricated concrete part, and a second lifting ring 311 is provided at the wellhead of each of the water collecting wells 31. In this way, the sand landfill layer 220 can be excavated first, and then modular installation can be performed through the second lifting ring 311, which improves efficiency and facilitates subsequent maintenance and replacement.

[0063] Specifically, a one-way permeable geomembrane is laid in each of the water collection wells 31 to allow water in the sand landfill layer 220 to flow into the water collection well 31 and prevent water in the water collection well 31 from flowing into the sand landfill layer 220, thereby reducing the amount of water in the slope.

[0064] For details, please refer to Figure 5 The side wall of each water collection well 31 is provided with a maintenance hidden door 4 and a pipe slot 312. The pipe slot 312 is used to fix and install the underground water pipe 32. The maintenance hidden door 4 is connected to the pipe slot 312. Each underground water pipe 32 is a metal corrugated pipe, and the pipe openings at both ends are provided with a third lifting ring 321. In this way, the staff can enter the water collection well 31 through the maintenance hidden door 4 to check the underground water pipe 32. The underground water pipe 32 is a metal corrugated pipe with a telescopic property and high strength, which is convenient for the installation and removal of the pipe. Then, the third lifting ring 321 can be hooked with a tool such as a hook to install or remove the underground water pipe 32, thereby improving efficiency.

[0065] Specifically, gates 313 are provided at both ends of each of the pipe slots 312; thus, when the gates 313 are in an open state, the water collection well 31 serves to drain water, and when the gates 313 are in a closed state, the water collection well 31 serves to store water.

[0066] Furthermore, based on the above-mentioned embodiment of "a maintenance secret door 4 and a pipe slot 312 are provided on the side wall of each of the water collection wells 31, the pipe slot 312 is used to fix the groundwater pipe 32, the maintenance secret door 4 and the pipe slot 312 are connected, each of the groundwater pipes 32 is a metal bellows, and a third lifting ring 321 is provided at its pipe mouth", when the groundwater pipe 32 is damaged, the staff can enter the water collection well 31 through the maintenance secret door 4, first open the gate 313, use a hook or other tool to fasten the third lifting ring 321, and remove the damaged groundwater pipe 32 from the pipe slot 312.

[0067] Specifically, the stratified drainage system 100 for slag slope also includes a driving component and a first control terminal. The driving component is connected to the gate 313 to drive the gate 313 to close or open. The first control terminal is electrically connected to the driving component. In this way, according to actual precipitation conditions, the staff can drive the driving component through the first control terminal to control the gate 313 to close or open, so that the water collection well 31 switches between drainage and water storage.

[0068] Furthermore, the driving member is a driving motor. Furthermore, the driving member is provided with a signal receiver, which is in communication connection with the signal transmitter 55 of the first control terminal.

[0069] It should be noted that, in the present invention, the form of the first control terminal is not limited, and it can be a computer, or a mobile phone or other terminal.

[0070] For details, please refer to Figures 1 to 3 ,as well as Figure 6 The underground drainage structure 3 also includes a plurality of inflatable structures 33 distributed at intervals, each of which includes an inflatable pipe 331, an inflatable pump 332 and an air pressure controller 333. The inflatable pipe 331 is extended along the slope height direction and inserted into the sand landfill layer 220 and the clay landfill layer 230; the inflatable pump 332 is connected to the inflatable pipe 331 and is used to fill the inflatable pipe 331 with gas; the air pressure controller 333 is arranged between the inflatable pipe 331 and the inflatable pump 332. In this way, when the permeability of the clay landfill layer 230 is low and drainage is difficult, the clay landfill layer 230 can be inflated by the inflatable pump 332 and the inflatable pipe 331, and the water in the slope body can be squeezed out by gas pressure into the water collection well 31 for drainage, which can effectively solve the problem of groundwater rising in the clay landfill layer 230. More specifically, the inflatable structure 33 is disposed close to the water collection well 31 .

[0071] For further information, see Figures 1 to 3 The stratified drainage system 100 for the muck slope also includes a groundwater level monitoring meter 5 and a second control terminal. The groundwater level monitoring meter 5 is arranged on the slope to monitor the groundwater level. The second control terminal is connected in communication with the groundwater level monitoring meter 5, the air pump 332, and the air pressure controller 333 to control the working state of the air pump 332 according to the monitoring data of the groundwater level monitoring meter 5, and when the air pump 332 is in the starting state, the air pressure filled in the air pipe 331 is controlled by the air pressure controller 333. In this way, the staff can control the start of the air pump 332 through the second control terminal according to the monitoring data of the groundwater level monitoring meter 5, thereby improving the drainage efficiency of the slope.

[0072] It should be noted that, in the present invention, the groundwater level monitoring meter 5 can be electrically connected to the air pump 332 through the second control terminal, and the groundwater level monitoring meter 5 can also be directly connected to the air pump 332 through communication, that is, when the groundwater level monitoring meter 5 detects that the groundwater level is too high and reaches the threshold that threatens the stability of the slope, it can directly control the air pump 332 to start, which is suitable for emergency situations to avoid the staff failing to operate the second control terminal in time, resulting in untimely drainage and instability of the slag slope 200. More specifically, the inflatable structure 33 also includes a first signal transmitter 335, and the second control terminal is connected to the air pump 332 and the air pressure controller 333 through the first signal transmitter 335.

[0073] Further, based on the above-mentioned embodiment of "a gate 313 is provided at both ends of each of the pipe slots 312, the slag slope stratified drainage system 100 also includes a driving member and a first control terminal, the driving member is drivingly connected to the gate 313 to drive the gate 313 to close or open; the first control terminal is electrically connected to the driving member", while the second control terminal controls the air pump 332 to start, the first control terminal also controls the driving member to open the gate 313, so that the water in the water collection well 31 can flow out through the underground channel and the transverse drainage ditch 23 to allow the water in the clay landfill layer 230 to flow in.

[0074] Furthermore, the driving component is directly connected to the groundwater level monitoring meter 5 for communication. When the groundwater level monitoring meter 5 detects that the groundwater level is too high and reaches a threshold that threatens the stability of the slope, the driving component can be directly controlled to drive the valve to open, which is suitable for emergency situations.

[0075] It should be noted that, in the present invention, the first control terminal and the second control terminal may be two independent control terminals or the same control terminal.

[0076] For details, please refer to Figure 6 The inflatable structure 33 also includes a solar panel 334, and the solar panel 334 is electrically connected to the air pump 332 and the air pressure controller 333 to achieve solar power supply, energy saving and environmental protection.
