Description

Technical Field

[0001] This utility model relates to the field of vertical seepage prevention construction technology for landfills, and more specifically, to an integrated trenching and membrane laying device. Background Technology

[0002] Vertical anti-seepage systems in solid waste landfills typically construct a vertical sealing layer above an impermeable or weakly permeable layer beneath the landfill foundation. This system effectively traps leachate and generated gases within the landfill, allowing for controlled extraction. This prevents leachate from seeping into the surrounding groundwater and avoids the uncontrolled release of gases from the landfill. It also prevents surrounding groundwater from flowing into the landfill.

[0003] Currently, in the process of vertical seepage prevention construction in landfills, trench excavation and geomembrane laying are two separate procedures. First, trenches need to be excavated, then geomembranes need to be laid in the excavated trenches, then the geomembranes need to be anchored, and finally the trenches need to be filled.

[0004] However, after conventional chain trenching machines excavate trenches, the soil slope at the trench opening is prone to collapse, resulting in problems such as hole collapse and trench collapse. This leads to incomplete trench openings, which usually require manual shaping and finishing, resulting in a waste of human resources, extended construction period, and affecting the smooth construction of subsequent geomembrane laying. Utility Model Content

[0005] Therefore, the purpose of this utility model is to design an integrated trenching and membrane laying equipment. The trenching machine is designed as an independent chain machine with separate lower and sidewall sections. The lower chain machine first trenches downwards at the front end. If a hole collapses, the fallen soil will be conveyed upwards to the sidewall chain machine and return to the ground, thus reducing the need for repeated excavation at collapsed locations and improving trenching efficiency. The membrane laying machine is set on top of the chain machine and includes multiple rollers. The membrane laying speed is controlled by these rollers, allowing for more precise control of the amount of membrane laid. On flat ground, the geomembrane being laid can be directly welded to the geomembrane to be used later, reducing material preparation time and improving membrane laying efficiency.

[0006] This utility model provides an integrated trenching and membrane laying device, comprising: a trenching machine located at the bottom, a membrane laying machine mounted above the center of the trenching machine, the trenching axis of the trenching machine being perpendicular to the membrane laying and pulling direction of the membrane laying machine, the vertical height of the trenching machine being the same as the depth of the trench to be excavated, the membrane laying machine being connected to a geomembrane, and the membrane laying machine laying the geomembrane in the trench excavated by the trenching machine.

[0007] In traditional vertical seepage prevention construction, trenching and membrane laying are carried out in separate steps. After trenching, problems such as hole collapse and trench collapse often occur, requiring re-excavation of the trench. Membrane laying can only proceed after ensuring the trench is intact, resulting in low efficiency. This integrated trenching and membrane laying device combines a trenching machine and a membrane laying machine into a single unit. The chain-type trenching machine first excavates the trench downwards at its front end, and then the membrane is laid simultaneously after the trench is excavated, providing convenience for both trench excavation and membrane laying.

[0008] The vertical height of the trenching machine must be neither too small nor too large compared to the depth of the trench to be excavated. If the height of the trenching machine is too small compared to the depth of the trench, the soil excavated from the upper part of the machine will not be transferred to the surface, resulting in soil remaining in the trench. If the height of the trenching machine is too large compared to the depth of the trench, it will increase the transmission power of the trenching machine, leading to increased power consumption and energy waste. Furthermore, an excessively large height will raise the center of gravity of both the trenching machine and the film-laying machine, increasing the risk of the trenching machine tipping over. Therefore, this invention designs the height of the trenching machine to be equal to the depth of the trench to be excavated. This ensures that the trenching machine has high transmission performance, allowing all the excavated soil to be transferred to the surface, while also facilitating control of the trenching machine's power consumption and saving energy. At the same time, it limits the height of the center of gravity, improving the operational reliability of the trenching machine.

[0009] Furthermore, the grooving machine includes a main chain machine located in the middle and a side wall chain machine vertically arranged above the front and rear sides of the main chain machine. The chain movement direction of the side wall chain machine is the same as the chain rotation direction of the main chain machine, and the soil on the main chain machine is transferred to the side wall chain machine.

[0010] If a hole collapses, because the chains of the main chain machine and the side wall chain machine rotate in the same direction, the fallen soil will be conveyed back up to the side wall chain machine and return to the ground with it. There is no need to re-excavate the collapsed hole, which improves the trench excavation efficiency and saves labor costs.

[0011] Furthermore, both the main chain machine and the side chain machine are fixedly equipped with multiple cutter bars that are evenly arranged at equal intervals along the chain movement direction. Each cutter bar is connected to a coaxial scraper, and the upper and lower edges of the scraper in the width direction have cutting edges.

[0012] The width of the chain of the grooving machine can be set according to the required groove width. The main drive force on the chain-type grooving machine drives the cutter bar and scraper fixed on the chain to rotate. The blades on the scraper scrape the stratum.

[0013] Furthermore, the cross-section of the scraper in the width direction is an arc-shaped structure, and the concave side of the arc-shaped structure faces the direction of chain movement.

[0014] This utility model features a specially designed arc-shaped scraper cross-section, which, compared to existing straight-faced scrapers, can hold more soil over the same distance, more efficiently bringing the soil from the trench to the surface and increasing the trench excavation rate.

[0015] Furthermore, the scraper edges on both sides of the sidewall chain machine and the main chain machine are flush, and the center of the slotting axis of the main chain machine and the center of the side thickness direction of the sidewall chain machine are in the same plane.

[0016] If the scraper edges on both sides of the sidewall chain conveyor and the main chain conveyor are not aligned (misalignment occurs), the falling soil, after being picked up by the scraper of the main chain conveyor, will not be caught by the sidewall chain conveyor at the misaligned position, thus reducing the efficiency of uploading the falling soil in the trench. Therefore, this device strictly aligns the scraper edges of the sidewall chain conveyor with the scraper edges of the main chain conveyor to ensure that all soil falling from the collapsed hole is uploaded.

[0017] The center of the grooving axis of the main chain machine is aligned laterally with the center of the thickness direction of the side wall chain machine, so that the weight of the grooving machine on both sides of the grooving axis is balanced, ensuring the overall structural stability of the grooving machine and realizing safe and stable grooving movement.

[0018] Furthermore, the film-laying machine includes multiple parallel rollers, one of which has its axis located near the center of the sprocket at the lower end of the sidewall chain machine, while the remaining rollers are located above the top of the grooving machine.

[0019] The lowest roller of the geomembrane laying machine is used to lay the geomembrane at the bottom of the trench. Therefore, the lowest roller is set at a low height, roughly level with the ground, to facilitate the laying of the geomembrane into the trench under the pull of this roller. Multiple rollers at the top of the machine are used to pull the geomembrane from the finished geomembrane rolls. Through the rolling of the upper rollers, a transmission motion is formed with the lower rollers, continuously pulling and laying the geomembrane. Preferably, there is one lower roller and two upper rollers.

[0020] Furthermore, the sidewall chain machine includes a front sidewall chain machine and a rear sidewall chain machine arranged at the same height and in parallel. The front sidewall chain machine is located above the front side of the main chain machine, and the rear sidewall chain machine is located above the rear side of the main chain machine. The front sidewall chain machine and the rear sidewall chain machine operate in the same direction.

[0021] With two side-wall chain conveyors installed, if the front side-wall chain conveyor fails to catch the falling soil conveyed by the main chain conveyor in the event of a hole collapse, the rear side-wall chain conveyor can continue to "pick up the leaks," catching the falling soil conveyed by the main chain conveyor and transporting it to the ground, thus improving the reliability of upward transmission of collapsed soil.

[0022] If the front and rear sidewall chain machines move in opposite directions, according to the law of conservation of momentum, the reverse momentum will offset part of the forward total momentum, reducing the grooving speed. This integrated grooving and film-laying device designs the front and rear sidewall chain machines to move in the same direction, ensuring all motion vectors are directed towards the grooving axis, maximizing the accumulation of forward total momentum and facilitating speed control during grooving operations.

[0023] Furthermore, the arc center of the scraper at the lowest point of the sidewall chain machine is on the same horizontal plane as the arc center of the scraper at the highest point of the main chain machine.

[0024] That is, the minimum distance between the scraper at the lowest point of the side wall chain machine and the scraper at the highest point of the main chain machine is zero, so as to minimize the height difference between the scrapers of the side wall chain machine and the main chain machine. This allows the falling soil to be smoothly transferred from the scraper of the main chain machine to the scraper of the side wall chain machine. After the scraper of the side wall chain machine catches the falling soil transferred by the main chain machine, it delivers the falling soil to the ground.

[0025] Furthermore, the front sidewall chain machine and the rear sidewall chain machine are symmetrical about their vertical centerlines in the length direction relative to the main chain machine.

[0026] That is, the distance between the centers of the front sidewall chain machine and the main chain machine in the longitudinal direction is equal to the distance between the centers of the rear sidewall chain machine and the main chain machine in the longitudinal direction. If the centers of the front and rear sidewall chain machines are not symmetrical with respect to the main chain machine in the longitudinal direction, the grooving machine is likely to tilt forward or backward due to the pulling force during the membrane laying process. This will cause an imbalance in the movement trend and force during the grooving process, affecting the smooth progress of the grooving construction and also affecting the safe operation of the membrane laying.

[0027] Furthermore, the two sprockets of the main chain machine are the same size; the two sprockets of the front sidewall chain machine and the two sprockets of the rear sidewall chain machine, a total of four sprockets, are all the same size.

[0028] This integrated grooving and film-laying device features four identical sprockets on the front and rear of the sidewall chain machine, improving the overall structural stability of the transmission process. The two sprockets on the main chain machine are also designed to be identical, ensuring the structural symmetry of the grooving machine and reducing the selection requirements for the sprockets on the sidewall chain machine (if the front and rear sprockets of the main chain machine are not identical, the four identical sprockets on the front and rear sidewall chain machines cannot be directly selected, requiring complex calculations and adjustments). This facilitates the production and assembly of the device, improves its applicability, and makes it easier for mass production and widespread application.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] The integrated trenching and membrane laying equipment provided by this utility model has a simple and reasonable structure with strong overall integrity. The trenching machine is designed as an independent chain machine for the lower and side walls. The lower chain machine first trenches downwards at the front end. If a hole collapses, the fallen soil will be conveyed upwards to the side wall chain machine and return to the ground with it, reducing the traditional need for repeated excavation at the collapsed hole location and improving trench excavation efficiency. The membrane laying machine is set on the upper side of the chain machine. The membrane laying machine contains multiple rollers, which control the membrane laying speed and more precisely control the amount of membrane laid. On flat ground, the geomembrane being laid can be directly welded to the geomembrane to be used later, reducing material preparation time, improving membrane laying efficiency, and having high applicability and broad application prospects.

[0040] Example

[0041] This utility model embodiment provides an integrated grooving and film-laying device, see [link / reference]. Figure 1 As shown, the trenching machine 1 is located at the bottom of the equipment. The vertical height of the trenching machine 1 is the same as the depth of the trench to be excavated. This ensures that the trenching machine 1 has high transmission performance, so that all the soil excavated by the trenching machine 1 can be transferred to the ground surface. It also makes it easier to control the power consumption of the trenching machine 1 and save energy. At the same time, it limits the height of the center of gravity and improves the operational reliability of the trenching machine 1. The grooving machine 1 includes a main chain machine 11 located in the middle and side wall chain machines vertically arranged above the front and rear sides of the main chain machine 11. The side wall chain machines include a front side wall chain machine 12 and a rear side wall chain machine 13, both at the same height and arranged parallel to each other. The front side wall chain machine 12 is located above the front side of the main chain machine 11, and the rear side wall chain machine 13 is located above the rear side of the main chain machine 11. When a hole collapses, if the front side wall chain machine 12 fails to catch the falling soil conveyed by the main chain machine 11, the rear side wall chain machine 13 can continue to "pick up" the remaining soil, catching it and conveying it to the ground, thus improving the reliability of upward conveying of collapsed soil. The front side wall chain machine 12 and the rear side wall chain machine 13 operate in the same direction. Figure 2As shown, the front sidewall chain machine 12 and the rear sidewall chain machine 13 are designed to move in the same direction, so that all motion vectors are directed towards the forward direction of the grooving axis, maximizing the total momentum forward and facilitating speed control of the grooving operation.

[0042] Both the main chain machine 11 and the side chain machine are fixedly equipped with multiple cutter bars evenly spaced along the chain's direction of movement. Coaxial scrapers 4 are connected to the cutter bars, and the upper and lower edges of the scrapers 4 have cutting edges 41 in the width direction. The main driving force on the grooving machine 1 drives the cutter bars and scrapers 4 fixed to the chain to rotate. Figure 2 As shown, the blade 41 on the scraper 4 scrapes the stratum. The cross-section of the scraper 4 in the width direction is an arc-shaped structure, with the concave side of the arc-shaped structure facing the direction of chain movement. Compared with the existing straight-face scraper, the arc-shaped scraper cross-section can hold more soil over the same movement distance, more efficiently bringing the soil in the trench to the surface. The edges of the scrapers 4 on both sides of the sidewall chain machine and the main chain machine 11 are flush, and the center of the grooving axis of the main chain machine 11 and the center of the sidewall chain machine in the thickness direction are in the same plane. The alignment of the scrapers 4 on both sides of the sidewall chain machine and the scrapers 4 on the main chain machine 11 ensures that all soil falling from the collapsed hole is transported back up. The lateral alignment of the center of the grooving axis of the main chain machine 11 and the center of the thickness direction of the sidewall chain machine ensures that the weight of the grooving machine 1 is balanced on both sides of the grooving axis, ensuring the overall structural stability of the grooving machine 1 and achieving safe and stable grooving movement.

[0043] The center of the arc of the lowest scraper 4 of the side wall chain conveyor is on the same horizontal plane as the center of the arc of the highest scraper 4 of the main chain conveyor 11. That is, the maximum distance between the lowest scraper 4 of the side wall chain conveyor and the highest scraper 4 of the main chain conveyor 11 is zero, minimizing the height difference between the scrapers of the side wall chain conveyor and the main chain conveyor 11. This allows the falling soil to be smoothly transferred from the scraper 4 of the main chain conveyor 11 to the scraper 4 of the side wall chain conveyor. The scraper 4 of the side wall chain conveyor catches the falling soil transferred from the main chain conveyor 11 and then delivers it to the ground. The front side wall chain conveyor 12 and the rear side wall chain conveyor 13 are symmetrical about their vertical centerlines along the length of the main chain conveyor 11. In other words, the center-to-center distance along the length of the front sidewall chain machine 12 and the main chain machine 11 is equal to the center-to-center distance along the length of the rear sidewall chain machine 13 and the main chain machine 11. Under the pulling force during the membrane laying process, this maintains the movement trend and force balance of the grooving machine 1, ensuring the smooth progress of grooving construction and guaranteeing safe membrane laying operation. The two sprockets 5 of the main chain machine 11 are of the same size; the two sprockets 5 of the front sidewall chain machine 12 and the two sprockets 5 of the rear sidewall chain machine 13, a total of four sprockets 5, are all of the same size. The identical size of the four sprockets 5 of the sidewall chain machine improves the overall structural stability of the transmission process. The identical size of the two sprockets 5 of the main chain machine 11 ensures the structural symmetry of the main body of the grooving machine 1, reduces the selection requirements for the sprockets 5 of the sidewall chain machine, facilitates the production and assembly of the device, and improves its applicability. The chain movement direction of the sidewall chain machine is the same as the chain rotation direction of the main chain machine 11, and the soil on the main chain machine 1 is transferred to the sidewall chain machine. If a hole collapses, because the chains of the main chain machine 11 and the side wall chain machine rotate in the same direction, the fallen soil will be conveyed back up to the side wall chain machine and return to the ground with it, without needing to re-excavate the collapsed area.

[0044] A geomembrane laying machine 2 is mounted above the center of the trenching machine 1. The trenching axis of the trenching machine 1 is perpendicular to the geomembrane laying and pulling direction of the geomembrane laying machine 2. The geomembrane laying machine 2 is connected to the geomembrane 3, and lays the geomembrane 3 in the trench excavated by the trenching machine 1. In this embodiment, the integrated trenching and geomembrane laying device combines the trenching machine 1 and the geomembrane laying machine 2 into an integrated device. The trenching machine 1 first excavates the trench downwards at the front end, and after the trench is excavated, the geomembrane laying machine 2 simultaneously lays the geomembrane, providing convenience for trench excavation and geomembrane laying construction.

[0045] The geomembrane laying machine 2 includes multiple parallel rollers 21. The axis of one roller 21 is located near the center of the sprocket 5 at the lower end of the side-wall chain conveyor, while the remaining rollers 21 are located above the top of the grooving machine 1. The lowest roller 21 of the geomembrane laying machine 2 is positioned at a relatively low height, roughly level with the ground, for laying the geomembrane 3 at the bottom of the trench, facilitating its placement into the trench under the pull of this roller 21. The upper rollers 21 of the geomembrane laying machine 2 are used to pull the geomembrane 3 from the finished geomembrane roll. Through the rolling of the upper rollers 21, a transmission motion is formed with the lower rollers 21, continuously pulling and laying the geomembrane 3. In this embodiment, there is one lower roller 21 and two upper rollers 21.

[0046] The integrated trenching and membrane laying equipment in this embodiment has a simple and reasonable structure with strong overall integrity. The trenching machine is designed as an independent chain machine for the lower and side walls. The lower chain machine first trenches downwards at the front end. If a hole collapses, the fallen soil will be conveyed upwards to the side wall chain machine and return to the ground with it. This reduces the traditional need to repeatedly excavate the collapsed hole location and improves trenching efficiency. The membrane laying machine is set on the upper side of the chain machine. The membrane laying machine contains multiple rollers, which control the membrane laying speed and more precisely control the amount of membrane laid. On flat ground, the geomembrane being laid can be directly welded to the geomembrane to be used later, reducing material preparation time and improving membrane laying efficiency.
