Description

Technical Field

[0001] This invention relates to the field of construction surveying technology, and more specifically, to a settlement measurement device and method for highway tunnel construction. Background Technology

[0002] When highways cross mountains or other obstacles, they often use tunnels. During the excavation of shield tunnels, the surrounding soil is often disturbed, causing creep deformation towards the free face. To obtain timely information on ground deformation during excavation, appropriate monitoring methods must be employed. The disturbance to the surrounding soil during tunneling inevitably leads to ground settlement and deformation. A common practice is to deploy surface settlement monitoring points above the tunnel boring machine (TBM) route, measuring the changes in ground settlement to adjust TBM excavation parameters and scientifically guide construction.

[0003] Currently, most common settlement monitoring equipment uses a long pole to be inserted directly into the ground at a set depth at the monitoring point. Then, a three-dimensional spatial positioning device is installed on the long pole to obtain real-time ground settlement data at the monitoring point. However, the long pole is easily affected by geological changes, which can produce biased data. For example, soil loosening and sliding caused by heavy rainfall or soil displacement caused by underground animal activity can lead to angle deflection of the long pole or equipment settlement, resulting in erroneous data and greatly affecting the progress of tunnel construction. Summary of the Invention

The plastic sealing sheet 2 covers the air hole 2, and only one side of the plastic sealing sheet 2 is fixedly connected to the partition plate 2. The fixed ring 1, the sliding ring 1, the telescopic tube 3 and the telescopic tube 4 form a pumping chamber 1. The groove 1 is connected to the multi-way connecting assembly 1.

[0014] As a further optimization of the present invention, the multi-way connection component includes a three-way channel 1 disposed on a fixing ring 1 and a plug 1 detachably connected to a port of the three-way channel 1. The second and third ports of the three-way channel 1 are respectively connected to the groove 1 and the multi-channel 1.

[0020] Step 200: Introduce the medium into several root-like extension structures through the external pressure device until the medium pressure in the several root-like extension structures reaches the set value, then stop, seal the connection between the several root-like extension structures and the external pressure device, and disconnect from the external pressure device.

[0021] Step 300: Install the positioning mechanism on the end of the long pole located outside the soil, and obtain the initial three-dimensional coordinate positioning data of the end of the long pole located outside the soil. During the construction phase, obtain the initial three-dimensional coordinate positioning data of the end of the long pole located outside the soil at set time intervals.

[0022] The beneficial effects of this invention are as follows: This invention adds multiple retractable root-like extension structures to the long insertion rod. After the long insertion rod is inserted into the ground to a set depth, the multiple root-like extension structures are extended in multiple directions underground by external pressure, forming a tree root-like structure that forms a strong bond with the soil layer. This allows the single-point bond to expand into a multi-point bond, which can effectively improve the stability of the overall measuring equipment and reduce the generation of error data.

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0031] like Figures 1 to 6 As shown, a highway tunnel construction settlement measurement device includes:

[0032] Long insertion rod 1, the long insertion rod 1 being used to be inserted into the soil and form a limiting connection with the soil;

[0033] Positioning mechanism 2, which is detachably connected to the end of the long insertion rod 1 located outside the soil, is used to acquire three-dimensional coordinate data of the end of the long insertion rod 1 located outside the soil;

[0034] Several root-like extension structures 3 are evenly distributed along a spiral path on the long insertion rod 1. The root-like extension structures 3 are detachably connected to the external pressure device. When the external pressure device introduces the medium into the root-like extension structures 3, the root-like extension structures 3 are in an extended state. The root-like extension structures 3 in the extended state are used to expand the contact area between the long insertion rod 1 and the soil.

[0035] Several anti-clogging mechanisms 4 are respectively disposed at the openings of corresponding root-like extension structures 3. When the anti-clogging mechanism 4 is in an expanded state, it contacts the outer wall of the root-like extension structure 3. The positioning mechanism 2 includes a power storage module, a GPS module, a control circuit board, a communication module, etc., which are existing technologies, and their specific models and expansion slot settings will not be described in detail here.

[0036] It should be noted that when conducting settlement measurements, the long insertion rod 1 is driven into the soil at the set depth at the set monitoring point.

[0037] The medium is introduced into several root-like extension structures 3 by an external pressure device until the medium pressure in several root-like extension structures 3 reaches a set value and then stops. The connection between several root-like extension structures 3 and the external pressure device is sealed and the connection with the external pressure device is disconnected.

[0038] The positioning mechanism 2 is installed on the end of the long rod 1 located outside the soil, and the initial three-dimensional coordinate positioning data of the end of the long rod 1 located outside the soil is obtained. During the construction phase, the initial three-dimensional coordinate positioning data of the end of the long rod 1 located outside the soil is obtained once at a set time interval.

[0039] After construction is completed, the medium is introduced into several anti-clogging mechanisms 4 through external pressure equipment until the medium pressure in several anti-clogging mechanisms 4 reaches the set value and then stops. The connection between several anti-clogging mechanisms 4 and external pressure equipment is sealed and disconnected from external pressure equipment. Then, the medium in several root-like extension structures 3 is extracted through external pressure equipment. After extraction, the connection between several root-like extension structures 3 and external pressure equipment is sealed and disconnected from external pressure equipment.

[0040] Pull the long probe 1 out of the soil, and it can be used in subsequent measurement processes.

[0041] In an optional embodiment of the invention, such as Figure 1 , Figure 2 and Figure 6 As shown, the root-like extension structure 3 includes a storage groove 301 on the long insertion rod 1, a telescopic tube 302 and a telescopic tube 303 fixedly connected to the inner wall of the storage groove 301, and a drill bit 304 disposed in the storage groove 301. The other ends of the telescopic tube 302 and the telescopic tube 303 are fixedly connected to the drill bit 304. A sealed chamber 1 is formed between the telescopic tube 303, the drill bit 304 and the inner wall of the storage groove 301. A sealed chamber 2 is formed between the telescopic tube 302, the telescopic tube 303, the drill bit 304 and the storage groove 301. The long insertion rod 1 has a multi-channel 305 inside. Both the sealed chamber 1 and the sealed chamber 2 are connected to the multi-channel 305.

[0042] It should be noted that, as mentioned above, when the long insertion rod 1 is inserted into the soil to a set depth, all the root-like extension structures 3 are in the soil. At this time, the input end of the multi-chamber 305 can be connected to a check valve or a controllable valve, with a threaded connection. Then, the output pipe of the external pressure device is connected to the input end of the check valve or controllable valve, also with a threaded connection. After the connection is completed, air is pumped in through the external pressure device. The air is continuously supplied into the multi-chamber 305 and eventually enters the corresponding sealed chamber 1 and sealed chamber 2. The air pressure begins to push the drill bit 304 towards the soil outside the long insertion rod 1, and pulls the telescopic tube 302 and telescopic tube 303 to extend synchronously. During this extension process, hard rocks or soil clods may appear in the soil, hindering the drill bit 304. The drill bit 304, under the continuous push of air pressure, can generate component forces in other directions under the action of thrust and resistance, and extend along the direction of these component forces, forming an extension process similar to the growth of tree roots and stems. This allows the telescopic tube 1 302 and telescopic tube 2 303 to be stretched to their longest state. The uneven outer wall of telescopic tube 1 302 can generate the greatest bonding force with the soil. When the set pressure is generated in the sealed chamber 1 and sealed chamber 2, telescopic tube 1 302 and telescopic tube 2 303 are in an expanded and taut state, which can provide a stable limiting force for the long insertion rod 1. This can effectively bind most of the area around the long insertion rod 1 into one, thereby reducing the possibility of displacement of the long insertion rod 1 when the soil is loose, and effectively improving the accuracy of the data obtained by the positioning mechanism 2.

[0043] In an optional embodiment of the invention, such as Figure 1 , Figure 2 and Figure 6 As shown, the anti-clogging mechanism 4 includes an annular groove 401 located at the opening of the storage groove 301 and a bladder 402 fixedly connected to the inner wall of the annular groove 401. The long insertion rod 1 has a multi-channel second 403 inside, and the internal spaces of several bladders 402 are all connected to the multi-channel second 403.

[0044] It should be noted that, in order to improve the recycling capacity of the equipment, after construction is completed, the air in the first and second sealed chambers can be extracted again using external pressure equipment. This allows the first telescopic tube 302 and the second telescopic tube 303 to retract back into the receiving tank 301 under negative pressure. However, since the outer wall of the first telescopic tube 302 is in direct contact with the soil, it will carry soil with it during retraction. At this time, air can be introduced into the second multi-channel 403 using external pressure equipment, causing the bladder 402 to expand and bulge, making contact with the outer wall of the first telescopic tube 302. This effectively isolates a large amount of soil outside the storage trough 301, allowing only a small amount of soil to move into the storage trough 301 along with the telescopic tube 302. This portion of soil does not affect the drill bit 304 from eventually moving into the storage trough 301. However, after the long insertion rod 1 is pulled out, the gap between the telescopic tube 302 and the storage trough 301 needs to be thoroughly cleaned to prevent this portion of soil from drying and adhering to the telescopic tube 302. Long-term soil accumulation may eventually prevent the telescopic tube 302 from being completely retracted into the storage trough 301.

[0045] In an optional embodiment of the invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes an emergency control mechanism 5, which includes a one-way air pump assembly and a multi-way connection assembly 1 installed on the one-way air pump assembly. The internal space of the external pressure equipment and the one-way air pump assembly 1 are connected to the multi-channel 305 through the multi-way connection assembly 1.

[0046] The one-way air pump assembly includes a fixed ring 501 fixedly connected to a long insert rod 1, a sliding ring 502 slidably sleeved on the long insert rod 1, a telescopic tube 503 and a telescopic tube 505 connecting the fixed ring 501 and the sliding ring 502, several handles 504 hinged to the sliding ring 502, a through hole 506 on the sliding ring 502, a partition 507 fixedly connected to the inner wall of the through hole 506, an air hole 508 on the partition 507, a plastic sealing sheet 509 connected to the end face of the air hole 508 near the fixed ring 501, a groove 510 on the fixed ring 501, and a handle 504 fixedly connected to the long insert rod 1. The inner wall of the groove 510 has a partition 511, an air hole 512 on the partition 511, and a plastic sealing sheet 513 connected to the end face of the partition 511 away from the sliding ring 502. The plastic sealing sheet 509 covers the air hole 508, and only one side of the plastic sealing sheet 509 is fixedly connected to the air hole 508. The plastic sealing sheet 513 covers the air hole 512, and only one side of the plastic sealing sheet 513 is fixedly connected to the partition 511. The fixed ring 501, the sliding ring 502, the telescopic tube 503 and the telescopic tube 505 form a pumping chamber. The groove 510 is connected to the multi-way connection assembly.

[0047] The multi-way connection assembly includes a three-way channel 514 disposed on a fixing ring 501 and a plug 515 detachably connected to a port of the three-way channel 514. The second and third ports of the three-way channel 514 are respectively connected to the groove 510 and the multi-channel 305.

[0048] It should be noted that, as mentioned above, to improve the emergency performance of the equipment, such as when the external pressure equipment suddenly fails and cannot effectively pump in air, the handle 504 can be rotated to a suitable position, and then the sliding ring 502 can be moved up and down repeatedly by holding the handle 504. This causes the volume of the first pumping chamber to continuously increase and decrease. During the increase in volume, a negative pressure is generated inside the first pumping chamber. This negative pressure acts on the second plastic sealing sheet 513, allowing it to tightly cover the second air hole 512. When acting on the first plastic sealing sheet 509, the area of ​​the first plastic sealing sheet 509 not connected to the first air hole 508 bends towards the first pumping chamber, thus making the first air hole 508 open and allowing external air to be drawn into the first pumping chamber. When the volume of the first pumping chamber decreases, a positive pressure is generated inside. This positive pressure acts on the first plastic sealing sheet 509, causing the plastic sealing sheet to... When vent 509 tightly covers vent 508, and acts on plastic sealing sheet 513, it bends towards the three-way channel 514, thus connecting the pump chamber 1 with the three-way channel 514. At this time, the port 1 of the three-way channel 514 connected to the external pressure equipment is blocked by plug 515. Gas can only flow along the three-way channel 514 towards its port 3 to the multi-channel 305, thereby pressurizing the gas into the corresponding sealing chamber 1 and the sealing... In chamber two, once air can no longer be manually compressed, i.e., when the sliding ring 502 encounters significant resistance during downward movement, the construction status can be determined to be up to standard. In this embodiment, if the external pressure equipment is not faulty, the plug 515 can be removed from one end of the three-way channel 514 and connected to the external pressure equipment to perform the air pumping process. When extracting air, the air hole 508 needs to be sealed with a covering to extract the air from the sealed chamber one and the sealed chamber two.

[0049] In an optional embodiment of the invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it also includes an emergency control mechanism 2 6, which includes a one-way air pump assembly 2 and a multi-way connection assembly 2 located on the one-way air pump assembly 2. The external pressure equipment and the internal space of the one-way air pump assembly 2 are both connected to the multi-channel 2 403 through the multi-way connection assembly 2.

[0050] One-way air pump assembly 2 includes a fixed ring 2 601 fixedly connected to the long insert rod 1, a sliding ring 2 602 slidably sleeved on the long insert rod 1, a telescopic tube 5 603 and a telescopic tube 605 connected between the fixed ring 2 601 and the sliding ring 2 602, several handles 2 604 hinged to the sliding ring 2 602, a through hole 2 606 provided on the sliding ring 2 602, a partition 3 607 fixedly connected to the inner wall of the through hole 2 606, an air hole 3 608 provided on the partition 3 607, a plastic sealing sheet 3 609 connected to the end face of the air hole 3 608 near the fixed ring 2 601, a groove 2 610 provided on the fixed ring 2 601, and a fixed connection to the... The inner wall of the groove 2 610 has a partition 4 611, an air hole 4 612 on the partition 4 611, and a plastic sealing sheet 4 613 connected to the end face of the partition 4 611 away from the sliding ring 2 602. The plastic sealing sheet 3 609 covers the air hole 3 608, and only one side of the plastic sealing sheet 3 609 is fixedly connected to the air hole 3 608. The plastic sealing sheet 4 613 covers the air hole 4 612, and only one side of the plastic sealing sheet 4 613 is fixedly connected to the partition 4 611. The fixed ring 2 601, the sliding ring 2 602, the telescopic tube 5 603 and the telescopic tube 605 form a pumping chamber 2. The groove 2 610 is connected to the multi-way connection assembly 2.

[0051] The second multi-way connection component includes a second three-way channel 614 disposed on a second fixed ring 601 and a second plug 615 detachably connected to a port of the second three-way channel 614. The second and third ports of the second three-way channel 614 are respectively connected to the second groove 610 and the second multi-channel 403.

[0052] It should be noted that, as mentioned above, the working principle of emergency control mechanism 26 is the same as that of emergency control mechanism 15, both aimed at improving the emergency performance of the equipment. For example, if the external pressure equipment suddenly fails and cannot effectively pump in air, the handle 2604 can be rotated to a suitable position, and then the sliding ring 2602 can be moved up and down repeatedly by holding the handle 2604. This causes the volume of the pumping chamber 2 to continuously increase and decrease. During the increase in volume of the pumping chamber 2, a negative pressure is generated inside. This negative pressure acts on the plastic dense material. On the sealing sheet 613, the plastic sealing sheet 613 can tightly cover the air hole 612. When acting on the plastic sealing sheet 609, the area of ​​the plastic sealing sheet 609 not connected to the air hole 608 will bend towards the pump chamber 2, thereby making the air hole 608 open, allowing external air to be drawn into the pump chamber 2. When the volume of the pump chamber 2 decreases, a positive pressure is generated inside. This positive pressure acts on the plastic sealing sheet 609, making the plastic sealing sheet 609 tightly closed. When the covering vent 3 608 acts on the plastic sealing sheet 4 613, it bends towards the three-way channel 2 614, thus connecting the pump chamber 2 with the three-way channel 2 614. At this time, the port 1 of the three-way channel 2 614 connected to the external pressure device is blocked by the plug 2 615. Gas can only flow along the three-way channel 2 614 towards its port 3 into the multi-channel 2 403, thereby pressurizing the gas into the corresponding bladder 402. At this time, the number of reciprocating movements of the sliding ring 2 602 can be used to determine the pressure. The air pressure in the bladder 402 is controlled such that the bladder 402 can contact the surface of the telescopic tube 302 without affecting the telescopic tube 302's return movement. In this embodiment, if the external pressure device is not faulty, the plug 615 can be removed from one of the ports of the three-way channel 614 and connected to the external pressure device to perform the air pumping process. When extracting air, the air hole 608 needs to be sealed with a covering material to extract the air from the bladder 402. The covering material can be tape or similar objects.

[0053] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
