Description

Technical Field

[0001] This application relates to the field of blind drain drainage structure technology, and in particular to a prefabricated blind drain drainage structure and its paving method. Background Technology

[0002] Blind drains generally refer to underground drainage ditches dug into the foundation. These culverts typically contain several drainage pipes and seepage pipes, filled with a large amount of gravel. The drainage pipes are mostly rigid PVC pipes, used for draining groundwater or municipal water. The seepage pipes are mostly polypropylene blind drain pipes with high permeability and water absorption properties, used for seepage and filtration of groundwater within the blind drain.

[0003] In the construction of traditional blind drainage ditches, workers first pour a concrete base layer at the construction site. Then, they lay drainage pipes on the cured concrete base layer, connecting all the pipes end to end and fixing them to the concrete base layer. After that, seepage pipes are installed around the drainage pipes. Finally, crushed stone is evenly spread on the drainage pipes and seepage pipes, and concrete slurry is poured on the crushed stone to seal it.

[0004] However, drainage pipes and seepage pipes need to be laid sequentially at the blind ditch construction site in the order of drainage pipes first and seepage pipes second, and all drainage pipes also need to be connected end to end on site; this construction process is too cumbersome on the construction site, which leads to low construction efficiency for construction workers. Summary of the Invention

[0005] To address the issue of low efficiency in laying drainage pipes and seepage pipes on construction sites, this application provides a prefabricated blind drain structure and its installation method.

[0006] Firstly, the prefabricated blind drain structure provided in this application adopts the following technical solution:

[0007] A prefabricated blind drain structure includes a pipe-installing device for simultaneously installing drain pipes and seepage pipes. The pipe-installing device includes multiple pipe-installing bases, multiple pipe-abutting arc plates, multiple sets of pipe-connecting mechanisms, multiple sets of locking mechanisms, and multiple sets of pipe-abutting mechanisms. Each pipe-installing base is provided with a pipe-installing channel for installing the drain pipe. The pipe-installing channels of the multiple pipe-installing bases placed along the extension direction of the blind drain are connected end to end. At least one set of pipe-connecting mechanisms is provided in the side wall of one pipe-installing channel, and each set of pipe-connecting mechanisms is used to connect two drain pipes located in the pipe-installing channel end to end. One pipe-abutting arc plate is installed on the top wall of the pipe-installing base through at least two sets of locking mechanisms. The pipe-abutting arc plate abuts against the drain pipe facing the side wall of the pipe-installing channel. One seepage pipe is provided in the side wall of the pipe-abutting arc plate away from the pipe-installing channel through a set of pipe-abutting mechanisms.

[0008] By adopting the above technical solution, the drainage pipe is pre-installed in the pipe installation channel. The pipe connecting mechanism can connect the two drainage pipes installed on the two pipe installation bases. The pipe-stopping arc plate is installed on the pipe installation base through the locking mechanism, and then the pipe-stopping arc plate presses against the drainage pipe to limit the position of the drainage pipe on the pipe installation base. The seepage pipe is installed on the side wall of the pipe-stopping arc plate away from the drainage pipe through the pipe-stopping mechanism. The construction personnel transport the pipe installation bases pre-installed with the drainage pipe and seepage pipe to the blind ditch construction site, and then install the pipe installation bases in sequence along the extension direction of the blind ditch to realize the rapid installation of the drainage pipe and seepage pipe at the blind ditch construction site, which improves the construction efficiency of the construction personnel.

[0009] In one specific implementation, each of the tube mounting bases is provided with a size-adapted plug-in block and a supply slot at opposite ends; the two tube mounting bases placed along the extension direction of the blind drain are connected by plugging the plug-in block on one tube mounting base into the supply slot of the other tube mounting base.

[0010] By adopting the above technical solution, after the plug-in block is inserted into the cavity of the matching slot, multiple pipe mounting bases placed along the extension direction of the blind ditch can be connected, thereby ensuring the positional stability and application stability of the pipe mounting base at the blind ditch construction site, while facilitating installation and helping to improve the construction efficiency of construction personnel.

[0011] In one specific implementation scheme, each of the pipe channels is provided with a water-absorbing element for absorbing moisture in the side wall, and each of the pipe bases is also provided with multiple seepage channels that are inclined and penetrate through the side wall and communicate with the inner cavity of the pipe channel, with each seepage channel inclined toward the ground.

[0012] By adopting the above technical solution, the water-absorbing component is used to absorb the water that has penetrated into the pipe base, reducing the phenomenon of water flowing and spreading further at the pipe base; the seepage channel, which is inclined towards the ground, is used to allow the water that enters the inner cavity of the pipe channel to flow smoothly to the outside of the pipe base.

[0013] In one specific implementation scheme, each of the seepage channels is further provided with a seepage-slowing component in the sidewall. The seepage-slowing component includes a baffle screen, a connecting rod, and multiple flow-slowing plates. The baffle screen is disposed in the sidewall of the seepage channel and is located at the end of the seepage channel away from the pipe channel. All the flow-slowing plates are disposed on the outer peripheral wall of the connecting rod. All the flow-slowing plates are distributed at intervals along the axial direction of the connecting rod, and the outer peripheral dimensions of adjacent flow-slowing plates are different.

[0014] By adopting the above technical solution, multiple flow-damping plates with different outer circumferences are placed in the inner cavity of the seepage channel through connecting rods. Gaps are left between the flow-damping plates of different sizes and the side walls of the seepage channel to allow groundwater to flow, thereby slowing down the flow speed of groundwater. This helps the water-absorbing component to fully absorb water and reduces the phenomenon of a large amount of water accumulating instantly outside the pipe base.

[0015] In one specific implementation scheme, each set of the pipe connecting mechanism includes a pre-support plate, multiple pipe connecting bolts, and two sets of directional cylinders with inner diameters adapted to the outer diameters of the drain pipes. The pre-support plate is disposed within the side wall of the pipe mounting channel, and the two sets of directional cylinders are respectively disposed on opposite sides of the pre-support plate. A pipe connecting channel is provided through the side wall of the pre-support plate and within the inner cavity of the directional cylinder. The two drain pipes to be connected end to end are respectively inserted into the directional cylinders located on both sides of the pre-support plate, and the pipe connecting bolts fix the drain pipes and the directional cylinders, so that the two drain pipes are connected end to end.

[0016] By adopting the above technical solution, after the end of the drainage pipe near the directional cylinder is inserted into the inner cavity of the directional cylinder, the connecting bolt passes through the directional cylinder and is threaded onto the drainage pipe, so that the end of the drainage pipe inserted into the inner cavity of the directional cylinder is positioned in the inner cavity of the directional cylinder; through this connection method, all drainage pipes installed on the pipe mounting base can be connected end to end, improving the convenience and work efficiency of construction personnel in laying drainage pipes in blind ditches.

[0017] In one specific implementation scheme, each locking mechanism includes an extension plate, a fixing screw, and a stop nut; the extension plate is disposed on the pipe-abutting arc plate, the fixing screw is disposed on the top wall of the pipe mounting base, and the fixing screw passes through the extension plate; the stop nut is threadedly connected to the fixing screw, so that the pipe-abutting arc plate abuts against the drain pipe on the side wall of the pipe mounting channel.

[0018] By adopting the above technical solution, the fixing screw passes through the extension plate to limit the position of the abutment plate relative to the drain pipe; the stop nut is screwed on the fixing screw to quickly position the extension plate on the fixing screw, thereby making the abutment plate stably abut against the outer wall of the drain pipe, ensuring the positional stability and application stability of the drain pipe on the pipe mounting base.

[0019] In one specific implementation, each set of the pipe-stopping mechanism includes a pipe-stopping strap capable of elastic deformation, the two ends of which are fixed to the side wall of the pipe-stopping arc plate away from the pipe-installation channel, and the seepage pipe is pressed against the pipe-stopping strap and the pipe-stopping arc plate.

[0020] By adopting the above technical solution, after the pipe tie is stretched and deformed, the seepage pipe can be placed between the pipe tie and the pipe arc plate. Then, the pipe tie uses its own elastic deformation to press against the outer wall of the seepage pipe, thereby pressing the seepage pipe against the pipe arc plate, realizing the rapid and relatively stable installation of the seepage pipe.

[0021] In one specific implementation, the pipe-stopping mechanism further includes a correction component, which includes a top abutment plate and multiple piercing rods; the top abutment plate is disposed on the side wall of the pipe-stopping strap facing the pipe-stopping arc plate, and the multiple piercing rods are disposed on the side wall of the top abutment plate facing the pipe-stopping arc plate; the pipe-stopping strap is pressed against the outer wall of the seepage pipe through the top abutment plate, and the piercing rods are inserted into the seepage pipe.

[0022] By adopting the above technical solution, the top abutment plate increases the contact area between the abutment tube tie and the seepage tube, and the piercing rod can pierce into the inside of the seepage tube to limit the position of the seepage tube on the outer wall of the abutment tube arc plate, thereby reducing the phenomenon of the seepage tube moving significantly after absorbing water.

[0023] Secondly, this application also provides a method for paving a prefabricated blind drain structure, including the following paving steps:

[0024] Assemble the drain pipe: Place the drain pipe into the pipe mounting channel. Taking the installation of one drain pipe on two pipe mounting bases as an example, the two sets of pipe connecting mechanisms located on the two pipe mounting bases will jointly connect one drain pipe in the two pipe mounting channels that are connected end to end. The locking mechanism will install the pipe-abutting arc plate on the top wall of the pipe mounting base, so that the pipe-abutting arc plate abuts against the drain pipe facing the side wall of the pipe mounting channel.

[0025] Install the seepage pipe: Install the seepage pipe on the side wall of the pipe-supporting arc plate away from the pipe installation channel, and use the pipe-supporting mechanism to press the seepage pipe firmly against the pipe-supporting arc plate;

[0026] Pipe base placement: Transport the pipe base equipped with drainage pipe and seepage pipe to the blind ditch construction site, and place the pipe base into the blind ditch in sequence along the extension direction of the blind ditch.

[0027] By adopting the above technical solution, construction workers can quickly and efficiently install drainage pipes and seepage pipes on the pipe mounting base. After that, construction workers only need to install the pipe mounting base at the blind ditch construction site to achieve rapid laying of drainage pipes and seepage pipes at the blind ditch construction site.

[0028] In summary, this application has the following beneficial technical effects:

[0029] 1. The drain pipe is pre-installed in the pipe mounting channel. The connecting mechanism allows the two drain pipes installed on two mounting bases to be connected. The pipe-stopping arc plate is installed on the mounting base through a locking mechanism, and then the drain pipe is pressed against the pipe through the pipe-stopping arc plate to limit the position of the drain pipe on the mounting base. The seepage pipe is installed on the side wall of the pipe-stopping arc plate away from the drain pipe through the pipe-stopping mechanism. The construction personnel transport the mounting bases pre-installed with the drain pipe and seepage pipe to the blind ditch construction site, and then install the mounting bases in sequence along the extension direction of the blind ditch to realize the rapid installation of the drain pipe and seepage pipe at the blind ditch construction site, which improves the construction efficiency of the construction personnel.

[0030] 2. The absorbent component is used to absorb the water that has penetrated into the pipe base, reducing the phenomenon of water flowing and spreading further at the pipe base; the seepage channel, which is inclined towards the ground, is used to allow the water that enters the inner cavity of the pipe channel to flow smoothly to the outside of the pipe base.

[0038] This application discloses a prefabricated blind drain structure.

[0039] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0040] Reference Figure 1 A prefabricated blind drain structure includes a pipe-installing device 3 capable of simultaneously installing a drain pipe 1 and a seepage pipe 2. In this embodiment, the drain pipe 1 can be a corrugated wall drain pipe, and the seepage pipe 2 can be a flexible and easily deformable polypropylene blind drain pipe. The drain pipe 1 and the seepage pipe 2 can be pre-installed on the pipe-installing device 3. After the construction personnel transport the pipe-installing device 3 to the blind drain construction site, they only need to install the pipe-installing device 3 at the blind drain construction site to realize the laying of the drain pipe 1 and the seepage pipe 2 in the blind drain, thereby helping to improve the work efficiency of the construction personnel in installing the drain pipe 1 and the seepage pipe 2 at the construction site.

[0041] Reference Figure 1 and Figure 2 The pipe-installing device 3 includes multiple pipe-installing bases 31, each with a pipe-installing channel 311 extending horizontally along its length for installing the drain pipe 1. It should be noted that placing the multiple pipe-installing bases 31 along the extension direction of the blind drain allows the multiple pipe-installing channels 311 to be connected end-to-end. In this embodiment, a drain pipe 1 can be placed precisely in two connected pipe-installing channels 311.

[0042] Reference Figure 2 To improve the positional stability of multiple tube mounting bases 31 placed in the blind drain, each tube mounting base 31 is provided with a connector block 312 and a supply slot 313 at both ends along its length. The outer circumferential dimensions of the connector block 312 are matched with the inner diameter of the supply slot 313. When multiple tube mounting bases 31 placed along the extension direction of the blind drain are connected, the connector block 312 of one tube mounting base 31 is inserted into the supply slot 313 of another tube mounting base 31. This allows two tube mounting bases 31 that are close together to be quickly connected, thereby helping to ensure the positional stability of multiple tube mounting bases 31 installed simultaneously in the blind drain and the stability of the connection between the two ends.

[0043] Reference Figure 2 In order to enable multiple drain pipes 1 to be quickly connected on the pipe mounting base 31, the pipe mounting device 3 also has multiple sets of pipe connecting mechanisms 32. At least one set of pipe connecting mechanisms 32 is provided in each pipe mounting channel 311. In this embodiment, the number of pipe connecting mechanisms 32 in each pipe mounting channel 311 is one set.

[0044] Reference Figure 2Each pipe-connecting mechanism 32 includes a pre-support plate 321, multiple pipe-connecting bolts 322, and two sets of directional cylinders 323. The pre-support plate 321 is welded vertically to the inner bottom wall of the pipe-installing channel 311. It should be noted that the welding position of the pre-support plate 321 within the pipe-installing channel 311 can be adjusted according to the actual installation position of the drain pipe 1 within the pipe-installing channel 311. The inner diameter of the directional cylinder 323 is matched to the outer diameter of the drain pipe 1. The two sets of directional cylinders 323 are respectively welded to the two side walls in the width direction of the pre-support plate 321, and the central axes of the two sets of directional cylinders 323 are collinear.

[0045] Reference Figure 2 A horizontally extending pipe channel 3211 is also provided on the side wall of the pre-support plate 321. The central axis of the pipe channel 3211 is collinear with the central axes of the two sets of directional cylinders 323. One end of the drain pipe 1 located in the pipe channel 321 can be inserted into the side wall of any one of the directional cylinders 323. The rod of the connecting bolt 322 passes through the directional cylinder 323 and is threaded onto the side wall of the drain pipe 1, so that one end of the drain pipe 1 located in the inner cavity of the directional cylinder 323 is positioned in the inner cavity of the directional cylinder 323. When the drain pipes 1 located on both sides of the width direction of the pre-support plate 321 have their length ends positioned in the inner cavity of the directional cylinder 323, the drain pipes 1 located on both sides of the width direction of the pre-support plate 321 are simultaneously connected to the pipe channel 3211, thereby realizing the connection between the inner cavities of the two drain pipes 1 located on both sides of the width direction of the pre-support plate 321. It should be noted that in the blind drain, every two sets of pipe bases 31 constitute an installation system. Each installation system can be pre-installed with a drain pipe 1, and every two sets of installation systems can be connected through a drain pipe 1, thereby enabling all installation systems to be connected in the blind drain.

[0046] Reference Figure 2 To improve the application stability of the drain pipe 1 located in the pipe mounting channel 311, the pipe mounting device 3 also includes multiple pipe-abutting arc plates 33 and multiple sets of locking mechanisms 34. In this embodiment, the number of pipe-abutting arc plates 33 on each pipe mounting base 31 can be two. Each pipe-abutting arc plate 33 has a set of locking mechanisms 34 at both ends in the length direction. The locking mechanisms 34 are used to position the length direction end of the pipe-abutting arc plate 33 on the top wall of the pipe mounting base 31, so that the pipe-abutting arc plate 33 abuts against the drain pipe 1 towards the side wall of the pipe mounting channel 311.

[0047] Reference Figure 2Each locking mechanism 34 includes an extension plate 341, a fixing screw 342, and a stop nut 343. The extension plate 341 is welded horizontally to the end wall of the pipe-supporting arc plate 33 along its length. The fixing screw 342 is welded vertically to the top wall of the pipe mounting base 31 and passes through the extension plate 341. The construction personnel tighten the stop nut 343 onto the fixing screw 342, positioning the extension plate 341 on the fixing screw 342. At this time, the side wall of the pipe-supporting arc plate 33 facing the pipe mounting channel 311 can abut against the outer wall of the drain pipe 1, thereby reducing the phenomenon of large-scale swaying and movement of the drain pipe 1 within the pipe mounting channel 311.

[0048] Reference Figure 2 In order to ensure that the drainage pipe 2 can be stably installed on the pipe mounting base 31, the pipe mounting device 3 also includes multiple sets of pipe-stopping mechanisms 35. In this embodiment, each pipe-stopping arc plate 33 can be provided with three sets of pipe-stopping mechanisms 35 on the side wall away from the pipe mounting channel 311. The three sets of pipe-stopping mechanisms 35 are spaced apart and equidistantly distributed along the extension direction of the pipe-stopping arc plate 33.

[0049] Reference Figure 3 Each set of pipe-stopping mechanisms 35 includes a pipe-stopping strap 351 capable of elastic deformation. In this embodiment, the pipe-stopping strap 351 can be an elastic band made of nylon. The two ends of the pipe-stopping strap 351 in the length direction are respectively fixed to the side wall of the pipe-stopping arc plate 33 away from the pipe-installation channel 311 by rivets. The construction personnel pass the seepage pipe 2 through the pipe-stopping strap 351 and the pipe-stopping arc plate 33. The pipe-stopping strap 351 presses against the side wall of the seepage pipe 2 away from the pipe-stopping arc plate 33 through its own elastic deformation, thereby making the seepage pipe 2 stably positioned on the side wall of the pipe-stopping arc plate 33 away from the pipe-installation channel 311.

[0050] Reference Figure 3 In practical applications, the seepage pipe 2 absorbs some groundwater through its own permeability and water absorption properties. In order to reduce the phenomenon that the seepage pipe 2 will move significantly relative to the support pipe tie 351 or even detach from the support pipe tie 351 after absorbing excessive water, the support pipe mechanism 35 also includes a correction component 352.

[0051] Reference Figure 3 The correction component 352 includes a top abutment plate 3521 and multiple piercing rods 3522. The top abutment plate 3521 is glued to the side wall of the abutment tube tie 351 facing the abutment tube arc plate 33. In this embodiment, the width of the top abutment plate 3521 is greater than the width of the abutment tube tie 351 to increase the contact area with the drainage pipe 2.

[0052] Reference Figure 3Multiple piercing rods 3522 are welded to the side wall of the top abutment plate 3521 facing the abutment arc plate 33. In this embodiment, the piercing rods 3522 can be steel needles with a pointed end away from the top abutment plate 3521. After the abutment strap 351 is pressed against the outer wall of the seepage pipe 2 by the top abutment plate 3521, the piercing rods 3522 can pierce into the interior of the seepage pipe 2, thereby limiting the position of the seepage pipe 2 on the abutment arc plate 33 and reducing the phenomenon of large-scale movement of the seepage pipe 2 after water absorption.

[0053] Reference Figure 4 To reduce the seepage of groundwater into the pipe base 31, which could affect the drainage pipe 1, a water-absorbing component 4 is installed inside the side wall of the pipe channel 311. In this embodiment, the water-absorbing component 4 can be an absorbent sponge. The water-absorbing component 4 is glued to the side wall of the pipe channel 311 and is located between the drainage pipe 1 and the side wall of the pipe base 31 to absorb the water seeping from the seepage pipe 2.

[0054] Reference Figure 4 The side wall of the pipe mounting base 31 is also provided with an inclined water seepage channel 314. The water seepage channel 314 is inclined towards the ground, and the end of the water seepage channel 314 near the water absorption member 4 is located above the end away from the water absorption member 4. When water seeps out of the water absorption member 4, the water can flow out of the pipe mounting base 31 through the water seepage channel 314.

[0055] Reference Figure 4 and Figure 5 To control the water flow rate within the seepage channels 314, a seepage-slowing component 5 is installed inside the side wall of each seepage channel 314. The seepage-slowing component 5 includes a baffle filter 51, a connecting rod 52, and multiple flow-slowing plates 53. The baffle filter 51 is welded to the side wall of the seepage channel 314 and is located at the lower end of the seepage channel 314.

[0056] Reference Figure 5 Multiple flow-damping plates 53 are integrally formed on the outer peripheral wall of the connecting rod 52. These plates are spaced apart and equidistantly distributed along the length of the connecting rod 52, with adjacent plates having different outer peripheral dimensions. After the connecting rod 52 with the flow-damping plates 53 is inserted into the inner cavity of the seepage channel 314, a gap is left between the larger flow-damping plates 53 and the side wall of the seepage channel 314 to allow groundwater to pass through. The filter screen 51 abuts against the connecting rod 52, positioning the connecting rod 52 with the flow-damping plates 53 within the inner cavity of the flow exchange channel. Groundwater entering the inner cavity of the pipe channel 311 flows into the inner cavity of the seepage channel 314 and exits from the opening of the seepage channel 314 with the filter screen 51.

[0057] The implementation principle of a prefabricated blind drain structure in this application embodiment is as follows: After the construction personnel install the drain pipe 1 in the inner cavity of the pipe installation channel 311, the end of the drain pipe 1 close to the directional cylinder 323 is inserted into the side wall of the directional cylinder 323. Then, the directional cylinder 323 and the drain pipe 1 are fixedly connected by the pipe bolt 322.

[0058] The abutting arc plate 33 is placed against the drain pipe 1, so that the fixing screw 342 passes through the outer extension plate 341, and then the stop nut 343 is threaded onto the fixing screw 342 until the abutting arc plate 33 is pressed against the outer wall of the drain pipe 1 facing the side wall of the pipe mounting channel 311, so that the drain pipe 1 is positioned on the pipe mounting base 31.

[0059] The drainage pipe 2 is placed between the pipe-holding strap 351 and the pipe-holding arc plate 33. Through the elastic force of the pipe-holding strap 351 after being stretched, the pipe-holding strap 351 presses the drainage pipe 2 against the outer wall of the pipe-holding arc plate 33.

[0060] After the construction workers transport the pipe mounting base 31 pre-installed with drainage pipe 1 and seepage pipe 2 to the blind ditch construction site, they can quickly install drainage pipe 1 and seepage pipe 2 in the blind ditch by placing the pipe mounting base 31 in sequence along the extension direction of the blind ditch.

[0061] This application also discloses a method for laying a prefabricated blind drain structure, the method comprising the following laying steps:

[0062] Assemble the drain pipe: Place the drain pipe 1 into the pipe mounting channel 311. Taking the adaptation of one drain pipe 1 to be installed on two pipe mounting bases 31 as an example, the two sets of pipe connecting mechanisms 32 located on the two pipe mounting bases 31 jointly connect one drain pipe 1 in the two pipe mounting channels 311 that are connected end to end, so that one drain pipe 1 is pre-installed on the two sets of pipe mounting bases to form a set of installation systems.

[0063] The locking mechanism 34 installs the pipe-abutting arc plate 33 on the top wall of the pipe mounting base 31, so that the pipe-abutting arc plate 33 abuts against the side wall of the pipe mounting channel 311 and the drain pipe 1 is positioned inside the side wall of the pre-installed channel.

[0064] Assemble the seepage pipe: Install the seepage pipe 2 on the side wall of the pipe-supporting arc plate 33 away from the pipe-installing channel 311, and press the seepage pipe 2 against the pipe-supporting arc plate 33 through the pipe-supporting mechanism 35.

[0065] Pipe mounting base placement: Transport the pipe mounting base 31, which is equipped with drainage pipe 1 and seepage pipe 2, to the blind ditch construction site, and place the pipe mounting base 31 into the blind ditch in sequence along the extension direction of the blind ditch.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
