Description

Technical Field

[0001] This utility model relates to the field of box girder production technology, and in particular to a settlement monitoring system for girder foundations. Background Technology

[0002] Foundation settlement monitoring is a crucial measure to ensure structural safety. Due to the large volume and heavy weight of individual box girders in high-speed railways, strict leveling requirements are placed on the foundations of the girder storage platforms. Excessive settlement at a single location on the foundation can easily lead to overturning and safety accidents due to the large volume and weight of the girder. Routine foundation settlement monitoring typically involves setting settlement benchmarks and manual observation by surveyors using leveling instruments or total stations. The main drawbacks of traditional monitoring methods are: 1. The large volume of the box girders necessitates a large girder yard layout, requiring settlement monitoring to be conducted at both ends of different mileages, resulting in a large workload, low efficiency, and a large number of personnel required; 2. Significantly affected by weather conditions, complex weather can affect monitoring accuracy or prevent timely monitoring; 3. Human and instrumental errors in manual observation are also important factors affecting monitoring accuracy, leading to misjudgments of foundation settlement. Therefore, there is an urgent need to improve the reliability and timeliness of settlement monitoring results to ensure the safety of the stored girder. Utility Model Content

[0003] The purpose of this invention is to address the numerous shortcomings of traditional methods for monitoring the settlement of beam foundations in the background art, and to provide a beam foundation settlement monitoring system.

[0004] This utility model provides a settlement monitoring system for beam foundations, comprising:

[0005] The beam storage foundation includes several spaced-apart pile cap foundations, with strip foundations provided between adjacent pile cap foundations;

[0006] Multiple first static levels are provided, each set at the settlement point of the foundation cap and the strip foundation, and all first static levels are connected by a pressure-conducting water pipe.

[0007] The second static level is set at a reference point outside the foundation area of ​​the beam storage instrument, and the second static level is connected to the first static level through the pressure-conducting water pipe.

[0008] The data center is used to receive in real time the measured liquid level information of all the second hydrostatic level instruments and the reference liquid level information of the second hydrostatic level instruments.

[0009] The settlement monitoring system for beam foundations described in this application involves installing a first static level at the settlement points of the foundation cap and strip foundation, and a second static level at a reference point outside the beam foundation. A data center receives the measured liquid level information from all the second static levels and the reference liquid level information from the second static level. The measured liquid level information from the first static level reflects the settlement changes at each settlement point. The reference liquid level information from the second static level is then compared with the measured liquid level information from the first static level at each settlement point to calculate the relative settlement amount between each settlement point and the reference point. This beam foundation settlement monitoring system solves the technical problem of low accuracy in beam foundation settlement monitoring, as well as the technical problems of short sensor lifespan and poor stability. By receiving the measured liquid level information from the second static level and the reference liquid level information from the second static level in real time through the data center, real-time monitoring and tracking measurement of beam foundation settlement can be achieved.

[0010] Preferably, all the first static levels are connected in series in a ring via the pressure-conducting water pipe. By connecting all the first static levels in a ring, it is convenient to arrange them around the circumference of the foundation beam. This not only facilitates inspection and maintenance and reduces the complexity of the layout, but also reduces the impact of local non-uniformity on the measurement results.

[0011] Preferably, the system further includes a data acquisition device, wherein the first static level and the second static level are connected to the data acquisition device, and the data acquisition device is used to transmit the measured liquid level information of the first static level and the reference liquid level information of the second static level to the data center.

[0012] Preferably, the system further includes an adjustment platform, which is disposed at the bottom of the first static level and the second static level, and is used to adjust the vertical height of the first static level and the second static level.

[0013] The vertical height of the first and second static levels is adjusted by adjusting the platform, thereby ensuring that all second static levels and first static levels have the same installation elevation, and thus ensuring that all second static levels and first static levels have the same initial liquid level height.

[0014] Preferably, the adjustment platform includes a top plate, a bottom plate, and a wedge block, the wedge block being located between the top plate and the bottom plate, and the wedge block being able to slide laterally between the top plate and the bottom plate to adjust the vertical height of the top plate relative to the bottom plate;

[0015] The first static level and the second static level are connected to the top plate.

[0016] Preferably, the top plate has a first inclined surface at its bottom and the bottom plate has a second inclined surface at its top, and the first and second inclined surfaces are distributed in an inward V-shape.

[0017] The wedge block has an upper inclined surface at the top and a lower inclined surface at the bottom, and the upper and lower inclined surfaces are distributed in an inward V-shape.

[0018] The first inclined surface slides in conjunction with the upper inclined surface, and the second inclined surface slides in conjunction with the lower inclined surface.

[0019] Preferably, it further includes a screw arranged laterally between the top plate and the bottom plate, the wedge block being threadedly engaged with the screw, and the screw being able to drive the wedge block to move along the length direction of the screw.

[0020] Preferably, it also includes a support column, the two ends of which are detachably connected to the top plate and the bottom plate. A through hole is provided in the middle of the support column, and one end of the screw passes through the through hole and is threaded into the wedge block.

[0021] Preferably, the top plate has first inclined slides on both sides, and the bottom plate has second inclined slides on both sides. The first and second inclined slides on the same side are in an inward V-shape.

[0022] It also includes a sliding buckle, which is disposed on the wedge block. The sliding buckle has sliding parts at both the upper and lower ends. The upper sliding part is slidably disposed in the first inclined slide rail, and the lower sliding part is slidably disposed in the second inclined slide rail.

[0023] Preferably, both the first static level and the second static level are magnetostrictive static levels.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] The settlement monitoring system for beam foundations described in this application involves installing a first static level at the settlement points of the foundation cap and strip foundation, and a second static level at a reference point outside the beam foundation. A data center receives the measured liquid level information from all the second static levels and the reference liquid level information from the second static level. The measured liquid level information from the first static level reflects the settlement changes at each settlement point. The reference liquid level information from the second static level is then compared with the measured liquid level information from the first static level at each settlement point to calculate the relative settlement amount between each settlement point and the reference point. This beam foundation settlement monitoring system solves the technical problem of low accuracy in beam foundation settlement monitoring, as well as the technical problems of short sensor lifespan and poor stability. By receiving the measured liquid level information from the second static level and the reference liquid level information from the second static level in real time through the data center, real-time monitoring and tracking measurement of beam foundation settlement can be achieved.

[0045] Example 1

[0046] like Figure 1-5 The beam foundation settlement monitoring system described in this application includes:

[0047] The beam foundation 1 includes several spaced-apart pile cap foundations 2, and strip foundations 3 are provided between adjacent pile cap foundations 2.

[0048] Multiple first static level instruments 4 are installed at the settlement points of the foundation 2 and the strip foundation 3, and all first static level instruments 4 are connected by pressure-conducting water pipes 6.

[0049] The second static level 5 is set at a reference point outside the area of ​​the beam foundation 1. The second static level 5 is connected to the first static level 4 through a pressure-conducting water pipe 6.

[0050] The data center is used to receive the measured liquid level information of all second static level instruments 5 and the reference liquid level information of the second static level instrument 5 in real time.

[0051] By installing a first static level 4 at the settlement points of the foundation 2 and strip foundation 3, and a second static level 5 at a reference point outside the beam foundation 1, and receiving the measured liquid level information of all the second static level 5 and the reference liquid level information of the second static level 5 through a data center, the settlement changes of each settlement point are reflected by the measured liquid level information of the first static level 4. Then, the reference liquid level information of the second static level 5 is compared with the measured liquid level information of the first static level 4 at each settlement point to calculate the relative settlement amount of each settlement point to the reference point. The beam foundation settlement monitoring system of this embodiment solves the technical problem of low settlement monitoring accuracy of the beam foundation 1, and also solves the technical problems of short sensor life and poor stability. By receiving the measured liquid level information of the second static level 5 and the reference liquid level information of the second static level 5 in real time through the data center, real-time monitoring and real-time tracking measurement of the settlement of the beam foundation can be achieved.

[0052] In one or more implementations, such as Figure 1 As shown, all the first static level instruments 4 are connected in series in a ring through the pressure-conducting water pipe 6.

[0053] By connecting all the first static level instruments 4 in series into a ring, it is convenient to set them up around the foundation of the storage beam. This not only facilitates inspection and maintenance and reduces the complexity of the layout, but also reduces the impact of local non-uniformity on the measurement results.

[0054] In one or more embodiments, a data acquisition device is also included. The first static level 4 and the second static level 5 are connected to the data acquisition device via a cable. The data acquisition device is used to transmit the measured liquid level information of the first static level 4 and the reference liquid level information of the second static level 5 to the data center. The data acquisition device transmits the measured liquid level information and the reference liquid level information to the data center via online transmission. The data center receives the data and automatically calculates it to track and monitor the deformation of the monitored structure and the stress on key parts in real time.

[0055] In this embodiment, both the first static level 4 and the second static level 5 are magnetostrictive static levels. The magnetostrictive static level includes a storage tank filled with water. A vertical rod is also installed inside the storage tank, and a liquid level float is slidably mounted on the vertical rod. A magnetostrictive liquid level sensor is installed on the top of the storage tank. The magnetostrictive liquid level sensor measures the change in the liquid level height of the liquid surface where the liquid level float is located. The magnetostrictive liquid level sensor is connected to the data acquisition device through a cable, thereby transmitting the liquid level information of the static level to the data acquisition device and then to the data center.

[0056] The bottom of the storage tank is equipped with at least two liquid inlet pipe joints, which are connected to the storage tank. The pressure guide water pipe 6 is connected to the liquid inlet pipe joints, and the top of the storage tank is equipped with an air vent nut.

[0057] Example 2

[0058] like Figure 5 As shown in the figure, based on Embodiment 1, the beam foundation settlement monitoring system described in this embodiment further includes an adjustment platform 7. The adjustment platform 7 is set at the bottom of the first static level 4 and the second static level 5. The adjustment platform 7 is used to adjust the vertical height of the first static level 4 and the second static level 5.

[0059] The vertical height of the first static level 4 and the second static level 5 is adjusted by adjusting platform 7, thereby ensuring that all second static level 5 and first static level 4 are installed at the same elevation, and thus ensuring that all second static level 5 and first static level 4 have the same initial liquid level. This facilitates the accuracy of settlement information when the liquid level information of the second static level 5 is used to reflect the settlement information of each settlement point.

[0060] In optional implementations, such as Figure 6 As shown, Figure 5 , Figure 6 As shown, the adjustment platform 7 includes a top plate 71, a bottom plate 72, and a wedge block 73. The wedge block 73 is located between the top plate 71 and the bottom plate 72, and the wedge block 73 can slide laterally between the top plate 71 and the bottom plate 72 to adjust the vertical height of the top plate 71 relative to the bottom plate 72.

[0061] The first static level 4 and the second static level 5 are connected to the top plate 71.

[0062] The vertical height of the top plate 71 relative to the bottom plate 72 is adjusted by sliding the wedge block 73 laterally, thereby adjusting the elevation of the first static level 4 and the second static level 5 connected to the top plate 71.

[0063] In optional implementations, such as Figure 9 As shown, the bottom of the top plate 71 is provided with a first inclined surface 711, such as... Figure 10 As shown, a second inclined surface 721 is provided on the top of the base plate 72, and the first inclined surface 711 and the second inclined surface 721 are distributed in an inward V-shape.

[0064] like Figure 8 As shown, the wedge block 73 has an upper inclined surface 731 at the top and a lower inclined surface 732 at the bottom. The upper inclined surface 731 and the lower inclined surface 732 are distributed in an inward V-shape.

[0065] The first inclined surface 711 is in sliding engagement with the upper inclined surface 731, and the second inclined surface 721 is in sliding engagement with the lower inclined surface 732.

[0066] The first inclined surface 711 slides into the upper inclined surface 731, and the second inclined surface 721 slides into the lower inclined surface 732, thereby achieving lateral sliding between the top plate 71 and the bottom plate 72 of the wedge block 73. Furthermore, since the first inclined surface 711 and the second inclined surface 721 are arranged in an inward V-shape, and the upper inclined surface 731 and the lower inclined surface 732 are also arranged in an inward V-shape, when the wedge block 73 moves laterally towards the smaller end of the V-shape, the lower inclined surface 732 slides on the second inclined surface 721, causing the overall height of the wedge block 73 to gradually increase. Simultaneously, the sliding engagement between the upper inclined surface 731 and the first inclined surface 711 causes the height of the top plate 71 to increase vertically. Figure 11 ,;

[0067] When the wedge block 73 moves laterally toward the larger end of the figure-eight shape, the lower inclined surface 732 slides on the second inclined surface 721, causing the overall height of the wedge block 73 to gradually decrease. At the same time, the sliding cooperation between the upper inclined surface 731 and the first inclined surface 711 causes the height of the top plate 71 to decrease vertically.

[0068] In optional implementations, such as Figure 7 As shown, it also includes a screw 74 that is horizontally disposed between the top plate 71 and the bottom plate 72. The wedge block 73 is threadedly engaged with the screw 74, and the screw 74 can drive the wedge block 73 to move along the length direction of the screw 74.

[0069] The lateral movement direction of the wedge block 73 is controlled by rotating the screw 74, thereby adjusting the rise or fall of the top plate 71.

[0070] In optional implementations, such as Figure 7 As shown, it also includes a support column 75, which is detachably connected to the top plate 71 and the bottom plate 72 at both ends. The support column 75 has a through hole in the middle, and one end of the screw 74 passes through the through hole and is threaded into the wedge block 73.

[0071] The top plate 71 is provided with a first mounting hole 713, the bottom plate 72 is provided with a second mounting hole 723, and the support column 75 is placed in the first mounting hole 713 and the second mounting hole 723.

[0072] In an optional embodiment, the top plate 71 is provided with first inclined slide rails 712 on both sides, and the bottom plate 72 is provided with second inclined slide rails 722 on both sides. The first inclined slide rails 712 and the second inclined slide rails 722 located on the same side are in an inward V-shape.

[0073] It also includes a sliding buckle 76, which is disposed on the wedge block 73. The sliding buckle 76 has a sliding part 761 at both the upper and lower ends. The upper sliding part 761 is slidably disposed in the first inclined slide rail 712, and the lower sliding part 761 is slidably disposed in the second inclined slide rail 722.

[0074] The top plate 71 and the bottom plate 72 are connected by a sliding buckle 76. The sliding buckle 76 moves together with the wedge block 73, and the sliding parts 761 at the upper and lower ends of the sliding buckle 76 slide within the first inclined slide rail 712 of the top plate 71 and the second inclined slide rail 722 of the bottom plate 72. This ensures that the sliding buckle 76 is slidably connected to the top plate 71 and the bottom plate 72 during the lateral movement of the wedge block 73, thereby ensuring that the top plate 71 will not fall off during the lifting and lowering process.

[0075] In one or more implementations, such as Figure 2 As shown, the bottom of the foundation 2 at both ends is equipped with reinforcing piles, and the bottom of the strip foundation 3 is equipped with a construction waste base layer 9. The foundation 2 and the strip foundation 3 are reinforced concrete structures.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
