Description

Technical Field

[0001] This application relates to the technical field of tunnel structures and soil layer tunneling construction, and in particular to a garden tunnel construction structure and a tunnel construction method. Background Art

[0002] Currently, it is necessary to set up a transparent glass tunnel in the soil layer of the garden to facilitate the observation of the biological conditions and the growth of plant roots in the soil layer.

[0003] Currently, all existing transparent tunnels are set in water, such as undersea tunnels and lake-bottom tunnels.

[0004] However, there is no available experience for constructing and setting up a glass tunnel in the soil layer. Summary of the Invention

[0005] In order to efficiently and reasonably set up a glass tunnel in the soil layer, this application provides a garden tunnel construction structure and a tunnel construction method.

[0006] The first technical object provided by this application is to provide a garden tunnel construction structure, which adopts the following technical solutions:

[0007] Comprising

[0008] A construction shaft, vertically opened in the soil layer;

[0009] A tunnel, located in the soil layer and communicating with the construction shaft at one end;

[0010] A transparent tunnel body, located in the tunnel and comprising multiple unit sections connected in sequence;

[0011] An inflatable protection pad, having a solenoid valve and correspondingly wrapped around the two sides and the upper side of the outside of the unit section;

[0012] Wherein adjacent protection pads are abutted against each other in sequence, and a guiding channel is arranged at the middle position of the upper part of the protection pad, and the guiding channel is arranged along the length direction parallel to the tunnel body.

[0013] By adopting the above technical solutions, in order for the tunnel body to be smoothly installed in the tunnel, the excavation size of the tunnel is generally relatively large, so there will be a large space between the tunnel and the tunnel body. The inflatable protection pad is used to fill the gap between the tunnel body and the tunnel, so as to prevent the gravel on the tunnel from falling or collapsing and damaging the tunnel body.

[0014] After the tunnel body is installed, the inflatable protection pad can be taken out and then backfill mud can be filled between the tunnel body and the tunnel. The plant roots and rhizomes can grow and extend into the backfill mud layer, so as to observe the plant roots close to the tunnel body and the organisms in the soil layer.

[0015] Since the protection pad is inflatable, it can be taken out after deflation, which is convenient for operation.

[0016] Optionally: An iron block is provided on one side of the protection pad corresponding to the tunnel body, and an electromagnet is provided on the inner side of the tunnel body corresponding to the iron block.

[0017] By adopting the above technical solution, the protection pad can be adsorbed and fixed by arranging an electromagnet inside the tunnel body, so that the protection pad can be fixed and disassembled without damaging the tunnel body, avoiding damage to the tunnel body.

[0018] Optionally: The solenoid valve is located in the guiding channel.

[0019] By adopting the above technical solution, it is possible to avoid damage to the tunnel body caused by the contact between the solenoid valve and the tunnel body, and also avoid damage to the solenoid valve caused by the contact between the solenoid valve and the inner wall of the tunnel.

[0020] Optionally: Each section of the protection pad is connected with a towing rope, and the towing rope passes through the guiding channel and extends to the construction well.

[0021] By adopting the above technical solution, during the process of taking out the protection pad, it is necessary to first deflate the protection pad at one end of the tunnel, and the protection pad can be pulled into the guiding tunnel by pulling the towing rope of the corresponding deflated protection pad. Deflate the protection pad in turn, and all the protection pads can be taken out of the tunnel.

[0022] Optionally: A conveying pipeline is arranged in the guiding channel.

[0023] By adopting the above technical solution, after each protection pad is deflated and taken out, due to the existence of the conveying pipeline, the backfill mud can be timely conveyed into the space originally provided with the protection pad, thereby timely filling the gap between the tunnel and the tunnel body, and thus avoiding the collapse of the tunnel.

[0024] Optionally: A slide rail is arranged at the bottom of the tunnel, and the slide rail extends to the construction well. The tunnel body is slidably connected to the slide rail, and a locking member is arranged at the bottom of the tunnel body for locking the tunnel body in the tunnel.

[0025] By adopting the above technical solution, after the unit section is installed in the tunnel, operate the locking member to fix the unit section in the tunnel, so that the unit section is firmly connected to the tunnel.

[0026] The second technical object provided by the present application provides a garden tunnel construction method, which adopts the following technical solution: including the following construction steps:

[0027] S1: Set up a construction well;

[0028] S2: Open a tunnel from the bottom of the construction well in one direction;

[0029] S3: Wrap an inflatable protective pad outside the unit section;

[0030] S4: Install the unit section in the tunnel;

[0031] S5: Inflate the inflatable protective pad;

[0032] S6: After the installation of the tunnel body is completed, deflate the protective pad and take it out, and then backfill between the tunnel and the tunnel body.

[0033] By adopting the above technical solution, first excavate the tunnel, and then install and splice the tunnel body in the tunnel, so that a glass tunnel located in the soil layer can be constructed without disturbing the soil layer surface.

[0034] In order to install the tunnel body smoothly in the tunnel, the excavation size of the tunnel is generally relatively large, so there will be a large space between the tunnel and the tunnel body. The inflatable protective pad is used to fill the gap between the tunnel body and the tunnel, so as to prevent the gravel on the tunnel from falling and damaging the tunnel body. Since the protective pad is inflatable, it can be taken out after deflation, which is convenient for operation.

[0035] Optionally: S4 includes the following steps:

[0036] S4-1: Erect a slide rail in the tunnel, and let part of the slide rail be in the construction shaft;

[0037] S4-2: Lift the unit section to the slide rail;

[0038] S4-3: Push the unit section into the tunnel.

[0039] By adopting the above technical solution, the unit section can be efficiently installed in the tunnel by sliding the unit section on the slide rail.

[0040] Optionally: S6 includes the following steps:

[0041] S6-1: Start deflating the protective pad from the end far from the construction shaft;

[0042] S6-2: Pull the deflated protective pad into the guiding channel of the adjacent non-deflated protective pad, and finally take it out of the tunnel;

[0043] S6-3: Fill the space on both sides of the tunnel body vacated by the deflated inflatable protective pad by setting a conveying channel in the guiding channel for conveying backfill mud.

[0044] S6-4: Repeat S6-1 to S6-3 until all the protective pads are taken out.

[0045] By adopting the above technical solution, after the protective pad is taken out, the space yielded by the protective pad can be filled, so as to stabilize the inner wall of the tunnel and prevent the inner wall of the tunnel from collapsing and damaging the tunnel body.

[0046] Optionally: after all the protective pads are taken out, the part between the tunnel at the tunnel entrance and the tunnel body is blocked, and then the space between the upper part of the tunnel body and the tunnel is filled with backfill mud.

[0047] By adopting the above technical solution, the part between the tunnel and the tunnel body is completely filled, so that the tunnel body can be completely wrapped by the backfill mud.

[0048] 1. Efficiently and completely install a transparent tunnel body in the tunnel, so as to observe the plant roots close to the tunnel body and the organisms in the soil layer;

[0049] 2. After each protective pad is deflated and taken out, due to the existence of the conveying pipeline, the backfill mud can be timely conveyed into the space originally provided with the protective pad, and then the gap between the tunnel and the tunnel body can be filled in time, thus avoiding the collapse of the tunnel;

[0050] 3. The installation of the tunnel body adopts trenchless construction. Through the above steps, on the premise of small-area excavation, a tunnel body made of glass material can be constructed in the soil layer. During the construction process, since only the construction well is excavated from the soil surface, the construction process does not damage the soil surface, and the soil surface can still be used for normal walking and vehicle passage, reflecting green and environmental protection construction.

[0055] The following is a further detailed description of the present application in conjunction with the attached Figure 1-2 drawings.

[0056] As Figure 1As shown in the figure, the construction structure of the garden tunnel disclosed in this application includes a construction shaft 1 vertically opened and a tunnel 3 horizontally arranged in the soil layer 2, and one end of the tunnel 3 is communicated with the lower end of the construction shaft 1.

[0057] A tunnel body 4 is arranged in the tunnel 3. The tunnel body 4 includes multiple unit sections 5 connected in sequence, and a waterproof sealing strip (not shown in the figure) is arranged between adjacent unit sections 5. Each unit section 5 includes a base 6 made of concrete and an arched top cover 7 fixed on the base 6. The top cover 7 is made of transparent glass.

[0058] As Figure 1 、 2 As shown in the figure, inflatable protection pads 8 are wrapped around the upper side and both sides of the outside of the unit section 5. The protection pads 8 are used to temporarily support the inner wall of the tunnel 3 during tunnel construction. The protection pads 8 are arched. A guiding channel 9 is arranged in the middle of the upper part of the protection pads 8. The guiding channel 9 is arranged along the length direction parallel to the tunnel body 4. An electromagnetic valve 10 is also fixed on the inner wall of the guiding channel 9. The protection pads 8 can be inflated through the electromagnetic valve 10 connected to an air pump. A PLC controller is arranged on the electromagnetic valve 10. The PLC controller is used to control the connection or disconnection of the power supply circuit of the electromagnetic valve 10 to control the opening and closing of the electromagnetic valve 10. The PLC controller also has a wireless communication module. By sending a wireless control signal to the wireless communication module, the wireless communication module transmits the received wireless control signal to the PLC controller. The PLC controller responds to the wireless control signal to connect the power supply circuit of the electromagnetic valve 10, so that the electromagnetic valve 10 is opened, realizing the deflation of the protection pads 8. The protection pads 8 fill the gap between the tunnel 3 and the tunnel body 4, thus avoiding damage to the tunnel body 4 caused by the collapse or falling stones of the tunnel 3.

[0059] As Figure 1 、 2 As shown in the figure, an iron block 11 is fixed on the side of the protection pad 8 corresponding to the tunnel body 4, and an electromagnet 12 is arranged on the inner side of the tunnel body 4 corresponding to the iron block 11. Rubber protective layers are sleeved outside both the electromagnet 12 and the iron block 11, thus avoiding scratching damage to the tunnel body 4 and enhancing the friction with the tunnel body 4, and further enabling the protection pad 8 to be more firmly combined with the tunnel body 4. The protection pad 8 is fixed by adsorbing with the electromagnet 12, so that the protection pad 8 can be fixed and disassembled without damaging the tunnel body 4.

[0060] As Figure 1 、 2As shown, each section of the protective pad 8 is connected to a towing rope 13, and the towing rope 13 extends through the guiding channel 9 to the construction well 1. After the tunnel body 4 is installed, it is necessary to remove the protective pad 8 and fill the gap between the tunnel 3 and the tunnel body 4. During the process of removing the protective pad 8, it is necessary to remotely control the opening of the solenoid valve 10 to deflate the protective pad 8 at one end of the tunnel 3, then unlock the electromagnet 12 and the iron block 11, and then pull the corresponding towing rope 13 of the deflated protective pad 8 to pull the protective pad 8 into the guiding tunnel and finally remove it.

[0061] The guiding channel 9 can also be used to thread a conveying pipeline 14, and the conveying pipeline 14 is used to convey backfill mud. After each protective pad 8 is deflated and removed, due to the existence of the conveying pipeline 14, the backfill mud can be timely conveyed into the space originally provided with the protective pad 8, thereby timely filling the gap between the tunnel 3 and the tunnel body 4, and thus avoiding the collapse of the tunnel 3. After the front-end backfill mud consolidates, the adjacent protective pad 8 can be deflated, and all the protective pads 8 can be removed from the tunnel 3 in sequence.

[0062] As Figure 1 , 2 shown, a slide rail 15 made of channel steel is fixed at the bottom of the tunnel 3. The slide rail 15 is composed of multiple unit segments spliced together. The slide rail 15 extends into the construction well 1, and a roller 16 located in the slide rail 15 is rotatably connected to the lower end of the base 6, so that the tunnel body 4 can be slidably connected to the slide rail 15. A locking member 17 is provided at the bottom of the tunnel body 4. The locking member 17 is a screw bolt screwed on the base 6 and penetrating into the bottom soil layer 2 of the tunnel 3. During the construction process, by using the slide rail 15 to slide the unit section 5 on the slide rail 15, the unit section 5 can be efficiently pushed into the tunnel 3. After the unit section 5 reaches the predetermined position, the screw bolt is rotated into the lower soil layer 2 of the tunnel 3 to lock the tunnel body 4 in the tunnel 3.

[0063] As Figure 1 , 2 shown, the disclosed garden tunnel construction method of the present application includes the following construction steps:

[0064] S1: Vertically excavate a construction well 1 in the soil layer 2.

[0065] S2: Horizontally excavate a tunnel  3 at the bottom of the construction well 7 so that one end of the tunnel 3 is communicated with the bottom of the construction well 1, and the bottom of the tunnel 3 is flush with the bottom of the construction well 7. The excavated tunnel 3 is large enough to conveniently accommodate the tunnel body 4.

[0066] S3: Wrap a layer of inflatable protective pad 8 outside the unit section 5.

[0067] S4: Installation of the unit section 5:

[0068] S4-1: Fix two mutually parallel slide rails 15 at the bottom of the tunnel 3. The slide rails 15 are made of channel steel and extend along the length direction of the tunnel 3, and part of the slide rails 15 extends into the construction shaft 7.

[0069] S4-2: Lift the unit section 5 into the construction shaft 7 and let the rollers 16 enter the slide rails 15.

[0070] S4-3: Push the unit section 5 into the tunnel 3.

[0071] S4-4: After the unit section 5 reaches the predetermined position, enter the lower soil layer 2 of the tunnel 3 through the rotating locking member 17 to lock the tunnel body 4 in the tunnel 3.

[0072] S5: Tunnel body 4 splicing:

[0073] S5-1: Inflate the inflatable protection pad 8 so that the protection pad 8 fills the space between the tunnel body 4 and the tunnel 3, thus preventing the gravel on the tunnel 3 from falling and damaging the tunnel body 4.

[0074] S5-2: Install the unit sections 5 in sequence, and let the towing ropes 13 on all the unit sections 5 pass through the guiding channels 9 and enter the construction shaft 1.

[0075] S5-3: Insert a waterproof sealing strip between adjacent unit sections 5 and apply waterproof glue.

[0076] S6: Backfilling

[0077] S6-1: Unlock the electromagnet 12, and then start deflating from the protection pad 8 at the end far from the construction shaft 1.

[0078] S6-2: Pull the deflated protection pad 8 into the guiding channel 9 of the adjacent non-deflated protection pad 8 and finally take it out of the tunnel 3.

[0079] S6-3: Fill the space on both sides of the tunnel body 4 vacated by the deflated inflatable protection pad 8 by setting a conveying pipe 14 in the guiding channel 9 for conveying backfill slurry. Since the backfill slurry is filled in time, it can effectively prevent the tunnel 3 from collapsing and affecting the tunnel body 4.

[0080] Among them, the backfill slurry is obtained by mixing the soil excavated from the tunnel 3 with water.

[0081] S6-4: After the backfill slurry consolidates, repeat S6-1 to S6-3 until all the protection pads 8 are taken out.

[0082] S7: After all the protective pads 8 are taken out, the part of the fixing plate between the tunnel 3 and the tunnel body 4 at the entrance of the tunnel 3 is blocked, and only an opening for the conveying pipeline to enter is left on the plate. Then, the space between the upper part of the tunnel body 4 and the tunnel 3 is filled with backfill slurry.

[0083] Among them, only the spaces on both sides of the tunnel body 4 are filled in S6-3 because of the existence of the guiding channel 9. If the backfill slurry is filled excessively, it will cause the backfill slurry to flow into the guiding channel 9.

[0084] In summary, the installation of the tunnel body 4 adopts trenchless construction. Through the above steps, a tunnel body 4 made of glass can be constructed in the soil layer 2 on the premise of small-area excavation. During the construction process, since only the construction well 1 is excavated from the surface of the soil layer 2, the construction process does not damage the surface of the soil layer 2, and the surface of the soil layer 2 can still be used for normal walking and vehicle passage, reflecting the green and environmental protection construction.

[0085] Moreover, in order to install the tunnel body 4 smoothly in the tunnel 3, the excavation size of the tunnel 3 is generally relatively large. Therefore, there is a relatively large space between the tunnel 3 and the tunnel body 4. During the construction process, an inflatable protective pad 8 is used to temporarily protect the tunnel body 4 and temporarily support the inner wall of the tunnel 3, which can prevent the gravel on the inner wall of the tunnel 3 from falling or collapsing and damaging the tunnel body 4.

[0086] After the tunnel body 4 is installed, the plant roots can grow and extend into the soil layer 2 after the backfill slurry layer is consolidated, so as to observe the plant roots close to the tunnel body 4 and the organisms in the soil layer 2.

[0087] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
