Description

Technical Field

[0001] This invention relates to the field of jacking construction, and in particular to a device for measuring the elevation difference of a horizontal jacking structure and its method of use. Background Technology

[0002] With the progress of the times and the development of society, tunnels and underground engineering are receiving increasing attention and are widely used in various fields such as transportation and logistics, municipal facilities, water conservancy and hydropower, resource storage, mineral development, and national defense. Fully developing and utilizing underground space is an inevitable trend for the sustainable development of cities, and urban underground engineering construction has now entered a new stage of development. In underground engineering construction, horizontal jacking structures are widely used, such as pipe jacking and tube jacking, and monitoring their vertical displacement is both a key focus and a challenge in construction.

[0003] Traditionally, before pipe jacking or pipe curtain construction, a benchmark point is set near the working shaft or receiving shaft. A high-precision level is typically used to determine the elevation of this benchmark point. As the pipe jacking progresses, workers periodically use a leveling rod to measure the height difference between the pipe's tip and the benchmark point, thus determining the height of the pipe's tip. While this method is direct, it is cumbersome and easily affected by environmental factors.

[0004] Another approach is to install tilt sensors on the jacking pipe or pipe curtain, which can acquire the tilt angle and position information of the jacking pipe front end in real time. Combined with the known jacking pipe length and initial height, the current height of the jacking pipe front end can be calculated. However, the disadvantages are that tilt sensors are relatively fragile and easily damaged, and require a continuous power supply. Summary of the Invention

Detailed Implementation

[0042] Example 1:

[0043] like Figure 1-14 In this invention, a horizontal jacking structure height difference measuring device includes a height measuring component 1 and a follower component 2 installed on a pipe body 5. The height measuring component 1 includes a barrel body 101, which is a cylindrical structure with an internal cavity. The barrel body 201 is perpendicular to the axial direction of the pipe body 5. A first connecting port 103 is provided at the lower end of the barrel body 101. A flexible bottom connecting pipe 3 connects the first connecting port 103 and the follower component 2. The upper ends of the barrel body 101 and the follower component 2 are connected to the outside. Liquid is contained inside the barrel body 101 and the follower component 2.

[0044] The barrel 101 has vertical scale lines. The height measuring component 1 is fixed to the ground or wall. The follower component 2 follows the tube 5 and is pushed horizontally forward. Initially, the liquid in the follower component 2 is adjusted to the middle height. At this time, the height of the height measuring component 1 is adjusted so that the water level is at zero. When the tube 5 is pushed forward, the height of the liquid level in the barrel 101 is monitored. The follower component 2 is installed at the front end of the tube 5. According to the principle of communicating vessels, when the liquid level in the barrel 101 increases, it means that the tube 5 is moving upward. When the liquid level in the barrel 101 decreases, it means that the tube 5 is moving downward. According to the direction of the height difference, the pushing direction of the tube 5 is adjusted in real time so that the tube 5 is always pushed horizontally.

[0045] In a preferred embodiment, the height measuring component 1 further includes a height measuring component adjustment device 4. The height measuring component adjustment device 4 is provided with a base 404, and two parallel and oppositely arranged supports 402 are provided on the base 404. The supports 402 are provided with a strip groove 405 and a ring frame 401. The inner side of the ring frame 401 is provided with an insertion rod part 407, which is rotatably inserted into the outer wall of the upper end of the barrel body 101. The outer side of the ring frame 401 is provided with two screw parts 406, and each screw part 406 is fitted with a threaded locking knob 403. The locking knob 403 is inserted into the strip groove 405. The insertion rod part 407 and the screw part 406 are arranged perpendicularly.

[0046] When the locking knob 403 is released, the ring frame 401 can move up and down with the barrel 101. The base 404 can be parallel to the length of the barrel 101, standing upright on the ground, or perpendicular to the length of the barrel 101, with its bottom end mounted on a wall. Both methods adjust the barrel 101 to be vertical. At this time, locking the locking knob 403 clamps the bracket 402, and the height of the ring frame 401 is fixed.

[0047] In a preferred embodiment, the upper end of the barrel 101 is open and is provided with a threaded protective cover 104. The inner wall of the protective cover 104 is provided with a plurality of air guide notches 105 along the circumferential direction. The inner top wall of the protective cover 104 is provided with a plurality of air guide grooves 106. One end of the air guide groove 106 is connected to the air guide notch 105, and the interior of the barrel 101 and the barrel body 201 is connected to the air guide groove 106.

[0048] The protective cover 104 of the height measuring component 1 and the follower component 2 have the same structure. The protective cover 104 is ventilated through a fine groove to prevent the upper end from being directly connected to the outside, thus achieving a dustproof effect. For the follower component 2, it can also prevent soil from entering the follower component 2 during the jacking process.

[0049] In the preferred embodiment, the follower 2 is a C-ring 6, and the C-ring 6 contains liquid.

[0050] The follower 2 is made into a C-shaped ring 6, which is wrapped around the inner or outer wall of the tube body 5. Because the protruding structure is more uniform, the jacking resistance can be reduced.

[0051] Furthermore, due to the larger internal volume of the C-ring 6, the liquid that can be contained is increased, and the height difference from the lowest to the highest point is increased, which increases the allowable liquid level difference variation and thus increases the measurable range of height difference.

[0052] In the preferred embodiment, the C-ring 6 includes a symmetrically arranged left half-ring 601 and a right half-ring 602. Each of the left half-ring 601 and right half-ring 602 has a balancing air port 603 at its upper end. The lower ends of the left half-ring 601 and right half-ring 602 are connected but not interconnected. Each of the left half-ring 601 and right half-ring 602 has a connecting air port 604 at its lower end. The left half-ring 601 and right half-ring 602 have a cavity 605 inside. A partition plate 107 is provided in the center of the barrel 101. The partition plate 107 divides the internal cavity of the barrel 101 into equal-volume compartments. Liquid is contained in the compartments and the cavity 605. Each compartment is provided with a third connecting port 102 and a first connecting port 103. There are two bottom connecting pipes 3. One end of each bottom connecting pipe 3 is connected to each connecting air port 604, and the other end of each bottom connecting pipe 3 is connected to the third connecting port 102 and the first connecting port 103, respectively.

[0053] The balance vent 603 connects to the external atmosphere to maintain air pressure balance.

[0054] Initially, the liquid levels in the left half-ring 601 and the right half-ring 602 are adjusted to be at the same height. When a difference in jacking height occurs, the liquid levels in the two compartments of the barrel 101 simultaneously decrease or increase. When the tube 5 rotates around its axis during jacking, a difference in liquid levels appears in the left half-ring 601 and the right half-ring 602, and a difference also appears in the liquid levels in the two compartments of the barrel 101. Based on this difference, the rotation deviation angle of the tube 5 can be calculated, and corresponding jacking adjustments can be made.

[0055] The cross-sectional area of ​​the cavity 605 is larger than that of the diaphragm of the barrel 101, making the changes in the liquid level inside the barrel 101 more obvious and facilitating a direct assessment of the height and spin attitude changes of the tube 5.

[0056] In the preferred embodiment, the outer wall of the front end of the tube body 5 is provided with an annular guide portion 7, and a back side space 701 is provided behind the annular guide portion 7. A C-shaped ring 6 is provided in the back side space 701, and a stop ring 8 is fitted on the outer wall of the tube body 5. The stop ring 8 abuts against the rear end of the C-shaped ring 6 and blocks the back side space 701.

[0057] The stop ring 8 has multiple mounting ears 801 along its circumference and is fixed to the outer wall of the tube body 5 by bolts.

[0058] The end face of the stop ring 8 presses against the C-ring 6 to prevent the C-ring 6 from rotating and slipping.

[0059] The stop ring 8 seals the back side space 701 to prevent soil or water from entering during the jacking process.

[0060] In the preferred embodiment, the outer wall of the pipe body 5 is provided with multiple protective pipe structures 503 along the circumference. A partition rib 504 is provided in the center of the protective pipe structure 503 to divide the interior of the protective pipe structure 503 into two independent channels. Two bottom connecting pipes 3 pass through the independent channels of the lowermost protective pipe structure 503 of the pipe body 5 to connect with the third connecting port 102 and the first connecting port 103 respectively. Two top vent pipes 301 are also provided. One end of each top vent pipe 301 is connected to the balance vent 603, and the other end passes through each independent channel of the protective pipe structure 503 to connect with the outside. The stop ring 8 is provided with multiple clearance notches 803 along the circumference. An arc-shaped protective plate 802 is provided on one side of each clearance notch 803. The arc-shaped protective plate 802 covers the protective pipe structure 503 near the annular guide part 7.

[0061] When jacking up dense soil layers, it is difficult for the soil layer to connect with the outside atmosphere to balance the air pressure. Therefore, it is necessary to introduce air from the outside at the rear end to balance the air pressure.

[0062] The left half-ring 601 and right half-ring 602 are equipped with quick-connect fittings at both ends for rapid pipe installation. The lower quick-connect fitting is perpendicular to the end face of the C-ring 6 and is located within the lowermost arc-shaped protective plate 802. For easier pipe installation at the upper end of the C-ring 6, since there is no arc-shaped protective plate 802 at the joint, the quick-connect fitting needs to be embedded in the back space 701 and bent at the uppermost clearance notch 803. To facilitate pipe installation, the pipe protection structure 503 cannot be too close to the annular guide portion 7. Therefore, an additional arc-shaped protective plate 802 needs to be welded to the stop ring 8 to cover the area between the pipe protection structure 503 and the annular guide portion 7, preventing dirt and moisture from entering.

[0063] In the preferred embodiment, each cavity of the barrel 101 is provided with a through threaded hole at its lower end. A plug screw 108 is threadedly connected to the through threaded hole. An L-shaped drain hole 109 is provided inside the plug screw 108. One end of the drain hole 109 is located on the outer wall of the plug screw 108, and the other end is connected to the outside.

[0064] Rotating the plug screw 108 connects the side wall port of the drain hole 109 to the inside of the diaphragm, allowing the liquid inside to be discharged from the bottom and adjusting the liquid level.

[0065] The preferred embodiment includes the following method of use: raising the jacking structure to the jacking height and adjusting the level of the tube body 5;

[0066] Install the height measuring component 1 and the C-ring 6 respectively;

[0067] The stop ring 8 is sleeved on the pipe body 5 so that each arc-shaped protective plate 802 is attached to each protective pipe structure 503.

[0068] The bottom connecting pipe 3 and the top vent pipe 301 are passed through the protective pipe structure 503, and the bottom connecting pipe 3 and the top vent pipe 301 are respectively connected to the height measuring component 1 and the C-ring 6.

[0069] Fit the C-ring 6 onto the end of the tube 5, and fill the left half ring 601 and the right half ring 602 with liquid so that the liquid level is in the middle position.

[0070] Fix the height of the height measuring device 1, and adjust the initial liquid level in the inner cavity of the barrel 101 to be at the same height and zero mark;

[0071] Slide the C-ring 6 horizontally into the back space 701 and observe the liquid level in the tank 101 to verify the horizontal status of the tube 5. The C-ring 6 can be made of transparent plastic and has a certain elasticity. It can slide on the tube 5 with the protective tube structure 503. If the tube 5 is horizontal, the liquid level in the C-ring 6 will remain unchanged during the sliding process, which will also reflect the unchanged liquid level in the tank 101.

[0072] Slide the stop ring 8 horizontally until its end face is pressed against the C-ring 6, and fix the stop ring 8 on the tube body 5;

[0073] The jacking operation was carried out, and the liquid level changes in the two compartments of tank 101 were monitored in real time.

[0074] Remove the measuring device after the measurement is completed.

[0075] Example 2:

[0076] like Figure 1-9In this invention, a height difference measuring device for a horizontal jacking structure includes a height measuring component 1 and a follower component 2 mounted on a pipe body 5. The height measuring component 1 includes a barrel body 101, and the follower component 2 includes a barrel body 201. The barrel body 101 and the barrel body 201 are cylindrical structures with internal cavities. The barrel body 201 is perpendicular to the axial direction of the pipe body 5. The lower end of the barrel body 101 is provided with a first connecting hole 103, and the lower end of the follower component 2 is provided with a second connecting hole 202. A flexible bottom connecting pipe 3 connects the first connecting hole 103 and the second connecting hole 202. The upper ends of the barrel body 101 and the barrel body 201 are connected to the outside, and liquid is contained inside the barrel body 101 and the barrel body 201.

[0077] The barrel 101 has vertical scale lines. The height measuring component 1 is fixed to the ground or wall. The follower component 2 follows the tube 5 and is pushed horizontally forward. Initially, the liquid in the follower component 2 is adjusted to the middle height. At this time, the height of the height measuring component 1 is adjusted so that the water level is at zero. When the tube 5 is pushed forward, the height of the liquid level in the barrel 101 is monitored. The follower component 2 is installed at the front end of the tube 5. According to the principle of communicating vessels, when the liquid level in the barrel 101 increases, it means that the tube 5 is moving upward. When the liquid level in the barrel 101 decreases, it means that the tube 5 is moving downward. According to the direction of the height difference, the pushing direction of the tube 5 is adjusted in real time so that the tube 5 is always pushed horizontally.

[0078] The pipe body 5 can be a jacking pipe or a pipe curtain. When it is a pipe curtain, the outer wall of the pipe body 5 is also provided with a hooking structure 501.

[0079] In a preferred embodiment, the height measuring component 1 further includes a height measuring component adjustment device 4. The height measuring component adjustment device 4 is provided with a base 404, and two parallel and oppositely arranged supports 402 are provided on the base 404. The supports 402 are provided with a strip groove 405 and a ring frame 401. The inner side of the ring frame 401 is provided with an insertion rod part 407, which is rotatably inserted into the outer wall of the upper end of the barrel body 101. The outer side of the ring frame 401 is provided with two screw parts 406, and each screw part 406 is fitted with a threaded locking knob 403. The locking knob 403 is inserted into the strip groove 405. The insertion rod part 407 and the screw part 406 are arranged perpendicularly.

[0080] When the locking knob 403 is released, the ring frame 401 can move up and down with the barrel 101. The base 404 can be parallel to the length of the barrel 101, standing upright on the ground, or perpendicular to the length of the barrel 101, with its bottom end mounted on a wall. Both methods adjust the barrel 101 to be vertical. At this time, locking the locking knob 403 clamps the bracket 402, and the height of the ring frame 401 is fixed.

[0081] In a preferred embodiment, the upper ends of the barrel body 101 and the barrel body 201 are open and provided with a threaded protective cover 104. The inner wall of the protective cover 104 is provided with a plurality of air guiding notches 105 along the circumferential direction, and the inner top wall of the protective cover 104 is provided with a plurality of air guiding grooves 106. One end of the air guiding groove 106 is connected to the air guiding notch 105, and the interior of the barrel body 101 and the barrel body 201 is connected to the air guiding groove 106.

[0082] The protective cover 104 of the height measuring component 1 and the follower component 2 have the same structure. The protective cover 104 is ventilated through a fine groove to prevent the upper end from being directly connected to the outside, thus achieving a dustproof effect. For the follower component 2, it can also prevent soil from entering the follower component 2 during the jacking process.

[0083] In a preferred embodiment, the upper end of the barrel 201 is provided with a filter element 203 with multiple pores.

[0084] Filter element 203 can further prevent soil particles from entering the interior of follower 2.

[0085] In the preferred embodiment, the side wall of the pipe body 5 is provided with a sloping stop 502, the follower 2 is fixed at the rear end of the sloping stop 502, and the rear end of the sloping stop 502 on the side wall of the pipe body 5 is also provided with a protective pipe structure 503, and the bottom connecting pipe 3 passes through the protective pipe structure 503.

[0086] The inclined baffle 502 can protect the follower 2 and reduce the jacking resistance. The protective tube structure 503 is a thin-walled steel structure that extends from the front end of the tube body 5 to the rear end. It has an internal cavity to protect the bottom connecting tube 3, which is thus led from the jacking area at the front end of the tube body 5 to the outside at the rear end.

[0087] In the preferred embodiment, two protective tube structures 503 are provided on the side wall of the tube body 5 along the height direction. The upper end of the follower 2 is also provided with a top vent pipe 301, which passes through the upper protective tube structure 503, and the bottom connecting pipe 3 passes through the lower protective tube structure 503.

[0088] When jacking up dense soil layers, it is difficult for the soil layer to connect with the outside atmosphere to balance the air pressure. Therefore, it is necessary to introduce air from the outside at the rear end to balance the air pressure.

[0092] Follower 2 is vertical and fixed to the front section of the horizontal jacking structure, with a bottom opening connected to the bottom connecting pipe 3.

[0093] The height measuring device 4 is placed on the ground and fixed to the height measuring device 1 by a ring frame;

[0094] The horizontal jacking structure can be a tube curtain or a jacking segment.

[0095] In the preferred embodiment, the height measuring component 1 is a barrel-shaped structure, fixed in the horizontal jacking structure to be measured. The barrel body 101 is equipped with a scale, the bottom is equipped with a drain valve 102 and a connecting hole 103, and the top is equipped with a protective cover 104.

[0096] The scale at the middle position of barrel 101 is set to zero.

[0097] The drain valve 102 can be opened or closed independently to regulate the amount of liquid in the container;

[0098] The connecting hole 103 is connected to the bottom connecting pipe 3;

[0099] The protective cover 104 has a structure with a sealed top and an open bottom. The opening is slightly larger than the diameter of the measuring component 1 barrel. It is placed on top of the measuring component barrel and is not sealed. The liquid inside the measuring component 1 is in contact with the air. The liquid surface pressure is the same as atmospheric pressure, which can ensure that the internal liquid does not overflow under the influence of construction vibration, and that external rainwater, dust and other pollutants do not seep into the measuring component 1.

[0100] In the preferred embodiment, the follower 2 has a barrel-shaped structure, including a barrel body 201, a connecting hole 202, a filter element 203, and a protective cover 104;

[0101] The connecting hole 202 is located at the bottom of the barrel body 201 and is connected to the bottom connecting pipe 3;

[0102] The filter element 203 has an inverted "Ω" shaped structure. The top ring plate is connected to the barrel body 201 to form a whole. The lower protrusion is a barrel-shaped structure with circumferential openings, allowing the liquid inside the follower 2 to communicate with the atmosphere.

[0103] The protective cover 104 of the follower 2 is a structure with a top seal and a bottom opening. The opening is slightly larger than the diameter of the follower 2 barrel and is placed on the top of the follower 2 barrel.

[0104] In the preferred embodiment, the bottom connecting tube 3 is a tubular structure with a certain degree of flexibility, which can be rolled up for storage. The inner core is made of steel wire tube, which has a certain pressure resistance. Even when bent, the internal liquid can still flow, ensuring the effectiveness of the communicating vessel.

[0105] In a preferred embodiment, the height measuring device 4 includes a ring frame 401, a bracket 402, a locking knob 403, and a base 404.

[0106] The ring frame 401 is a ring-shaped structure with a ring frame connection. Its inner side is connected to the top of the height measuring component 1, and its outer side is connected to the bracket 402, so that the height measuring component 1 remains vertical under the action of gravity.

[0107] The bottom of the bracket 402 is fixed on the base 404, and a slot is provided at the top. After the locking knob 403 is released, the ring frame 401 can drive the height measuring component 1 to move up and down.

[0108] The locking knob 403 connects the ring frame 401 and the bracket 402. The locking knob 403 is hinged to the ring frame 401. When loosened, the ring frame 401 can move up and down. When tightened, the ring frame 401 can only rotate along the bracket.

[0109] In the preferred embodiment, the liquid injected into the communicating vessel structure is generally water. When the environmental vibration is large, it is replaced with a liquid with a higher viscosity.

[0110] In the preferred embodiment, the communicating vessel is calibrated before use. The liquid level at the initial moment is kept at 0 by adjusting the height measuring device 1. If the liquid level cannot be kept at 0 by adjusting the height, water is added to the height measuring device or the drain valve 102 is opened to release water.

[0111] In the preferred embodiment, the diameter of the follower 2 is larger than the diameter of the height measuring component 1. The follower 2 is fixed in the horizontal jacking structure to be measured. When the jacking structure shifts up and down, the follower 2 moves accordingly. Due to the water balance and the interconnection of liquid surfaces, the liquid level in the height measuring component 1 also changes accordingly. The diameter of the height measuring component 1 is r1, and the diameter of the follower 2 is r2. When the jacking structure undergoes a vertical displacement x, the value in the height measuring component changes. Since r1 > r2, the displacement of the jacking structure is amplified, resulting in higher measurement accuracy.

[0112] In the preferred embodiment, when the jacking structure is a pipe curtain, the follower 2 is installed inside the grouting pipe; when the jacking structure is a jacking pipe, the follower 2 is fixed inside the jacking pipe.

[0113] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
