Description

Technical Field

[0001] The utility model relates to the field of foundation detection auxiliary components, in particular to a soil deformation monitoring platform for foundation detection. Background Art

[0002] The foundation refers to the expanded part of the wall or column of the house that is based on the foundation buried underground. The design and inspection of the foundation is an important part of the work of construction engineers. Before the building design, it is necessary to conduct an engineering geological survey of the construction site and conduct physical and mechanical property tests on the foundation to make a correct evaluation of the engineering geological conditions of the site. This is a prerequisite for good design and construction. Therefore, my country has long clearly stipulated that no design can be made without a survey report, and no construction can be made without design drawings.

[0003] Specifically in the process of foundation inspection, due to the characteristics of the soil and the changes in groundwater during the foundation excavation process, the soil will inevitably deform. Therefore, soil deformation monitoring is of great significance to ensure the safety of foundation pit excavation and construction quality. At present, when monitoring the soil deformation of the foundation, the monitoring method of exploration hole inclinometer is often used. During the operation, a monitoring well is first opened around the foundation pit, and then the inclinometer probe is inserted into the monitoring well to monitor and judge the displacement of the soil. However, when it comes to on-site operation, the operator usually holds the cable to lower the inclinometer probe to the specified position in the monitoring well. The depth of the inclinometer probe is difficult to maintain stably for a long time. At the same time, at the end of the measurement, the operator needs to pull the cable again to pull the inclinometer probe out of the monitoring well. The operation process is time-consuming and labor-intensive, and the accuracy and efficiency of the monitoring process are not high. Utility Model Content

[0017] The soil deformation monitoring platform for foundation detection is adopted as mentioned above, specifically when it is used for deformation monitoring of foundation soil, because the matching seat initially passes through the through-slotted hole and vertically slides with the matching slot, and at the same time the limit rod slides with the limit hole horizontally, then at this time the matching seat can be locked and cannot escape from the matching slot through the cooperation restriction of the limit rod and the limit hole, so that at this time the retractable assembly and the inclinometric deformation monitoring assembly are detachably fixed on the top of the top plate, and the fixing combination of the retractable assembly and the inclinometric deformation monitoring assembly and the top plate is simple and easy to operate, which makes it easy to quickly fix the retractable assembly and the inclinometric deformation monitoring assembly on the top plate to monitor the deformation of the soil. When in use, the lifting handle is lifted to move the top plate to the monitoring well at the monitoring position and the vertical plates are respectively placed on both sides of the monitoring well. At the same time, the inclinometer probe body should be suspended above the monitoring well. Then, after loosening the locking nut, the cable wound around the outer periphery of the drum can be wound or released by driving the drum to rotate forward and reversely through the screw rod. Then, during monitoring, the cable can be released by the drum rotating clockwise and driving the inclinometer probe body to be lowered into the monitoring well. At the same time, since the scale marks are printed on the surface of the cable, the inclinometer probe body can be lowered by referring to the scale marks during the process of lowering the inclinometer probe body. The height of the lowered position of the inclinometer probe body is locked by tightening the locking nut and pressing it against the side seat surface. Specifically, when referring to the height, first observe the scale value at which the scale mark is level with the top surface of the top plate when the inclinometer probe body is lowered to the bottom and is level with the top of the wellhead of the monitoring well. Then, based on this scale value, lower the cable until the increased scale number is consistent with the specified depth of the inclinometer probe body lowered into the monitoring well. After the inclinometer probe body reaches the specified depth, stop releasing the cable and tighten the locking nut. Then, operate the controller and regulate the inclinometer probe body to the monitoring well by wireless communication with the wireless signal transceiver. The soil inclinometer is measured at a specified depth, so as to realize the inclinometer deformation monitoring of the soil at the specified depth of the monitoring well by the inclinometer probe body, and the inclinometer probe body can be stably maintained at the specified depth in the monitoring well for a long time, and at the same time, it replaces the operation mode of personnel holding the cable to apply force to lower and pull up the inclinometer probe body, which reduces the work intensity and is conducive to improving the accuracy and efficiency of the monitoring process. When the measurement is completed, the locking nut is loosened and the roller is reversed counterclockwise to rewind the cable. At the same time, during the process of the cable being rewound, the inclinometer probe body rises and leaves the monitoring well, and then the top plate can be lifted and transferred to the next monitoring well to monitor the soil deformation again. After subsequent use,The matching seat can be vertically disengaged from the matching slot and the through-slot slot in sequence by simply pulling the limiting rod outward to disengage it from the limiting hole, and the retractable assembly and the inclination deformation monitoring assembly can be detached from the top position of the top plate.

At the same time, since the surface of the cable is printed with scale marks, the inclinometer probe body can be lowered to a specified depth of the monitoring well by referring to the scale marks during the process of lowering the inclinometer probe body, and the lowering position height of the inclinometer probe body can be locked by tightening the locking nut and pressing it against the side seat surface, so as to realize the inclinometer probe body to monitor the soil inclinometer deformation at a specified depth of the monitoring well, and can stably keep the inclinometer probe body at the specified depth in the monitoring well for a long time, and at the same time replace the operation mode of personnel holding the cable to apply force to lower and pull up the inclinometer probe body, which reduces the work intensity and is conducive to improving the accuracy and efficiency of the monitoring process;

[0019] 2.

The fixing combination of the retractable assembly and the inclinometer deformation monitoring assembly and the top plate is simple and easy to operate, which makes it easy to quickly fix the retractable assembly and the inclinometer deformation monitoring assembly on the top of the top plate for soil deformation monitoring;

[0020] 3. Only by pulling the limit rod out of the limit hole can the matching seat be vertically disengaged from the matching groove and the through-slot hole in turn to remove the retractable assembly and the inclination deformation monitoring assembly from the top position of the top plate. The separation method of the retractable assembly and the inclination deformation monitoring assembly from the top plate is simple and easy to operate, which is convenient for quickly removing the retractable assembly and the inclination deformation monitoring assembly from the top plate for regular inspection and maintenance in the later stage. At the same time, it is beneficial to improve the flexibility of the retractable assembly and the inclination deformation monitoring assembly when using them. BRIEF DESCRIPTION OF THE DRAWINGS

Such a configuration makes it easy to operate the controller 404 and adjust the inclinometer probe body 403 to perform soil inclinometer at a specified depth of the monitoring well by wireless communication with the wireless signal transceiver 405, so as to realize the inclinometer deformation monitoring of the soil at a specified depth of the monitoring well by the inclinometer probe body 403.

[0038] See also Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, disassembly and assembly components 5 are installed on both sides of the bottom surface of the top plate 2, and the disassembly and assembly components 5 are partially fixed to the bottom of both sides of the retractable component 1, and the retractable component 1 is detachably fixed to the top of the top plate 2 through the disassembly and assembly components 5. Specifically, the disassembly and assembly components 5 include a matching seat 504 and a fixing sleeve 501, and the bottom surface of the side seat 103 is vertically fixed with a matching seat 504, and the outer end surfaces of the matching seats 504 at the two side positions that are away from each other are horizontally provided with limiting holes 509, and the fixing sleeves 501 are vertically fixed on both sides of the bottom surface of the top plate 2, and the fixing sleeves 501 are vertically provided with matching grooves 505, both sides of the top surface of the top plate 2 are vertically provided with through slots 506, the through slots 506 correspond to the matching slots 505 one by one and are vertically connected to each other, the matching seats 504 pass through the corresponding through slots 506 and enter the matching slots 505 in a vertical sliding manner, the outer end surfaces of the fixing sleeves 501 at the two sides that are away from each other are horizontally provided with mounting holes 503, and the mounting holes 503 are vertically connected to the corresponding matching slots 505, the mounting holes 503 are horizontally coaxially slidably matched with the limit rods 508, and the inner ends of the limit rods 508 at the two sides that are close to each other are aligned with the corresponding The limiting holes 509 of the slidably mounted devices are laterally matched, and the outer ends of the limiting rods 508 at the two side positions that are away from each other extend out of the outer end faces of the corresponding fixing sleeves 501 and are coaxially fixed with handles 507. Preferably, the distance between the handles 507 and the corresponding vertical plates 3 is greater than the distance that the limiting rods 508 extend into the limiting holes 509, so as to ensure that the handles 507 can be pulled outward to drive the inner ends of the limiting rods 508 to completely escape from the corresponding limiting holes 509. The portion of the limiting rods 508 located between the corresponding handles 507 and the outer end faces of the fixing sleeves 501 is coaxially matched with springs 502, and the two ends of the springs 502 are respectively connected to the corresponding vertical plates 3. The corresponding handle 507 is fixedly connected to the outer end surface of the fixing sleeve 501. Such an arrangement makes it easy to detachably fix the retractable component 1 and the inclinometer deformation monitoring component 4 on the top of the top plate 2 by means of the matching seat 504 passing through the through-slot 506 and vertically sliding with the matching slot 505 and the limiting rod 508 and the limiting hole 509 horizontally slidingly cooperating. At the same time, it only takes the limiting rod 508 to be pulled out of the limiting hole 509 to make the matching seat 504 vertically disengaged from the matching slot 505 and the through-slot 506 in turn to remove the retractable component 1 and the inclinometer deformation monitoring component 4 from the top position of the top plate 2.

[0039] As the preferred solution in this case, see Figure 1 and Figure 2As shown, the outer end of the screw 105 passing through the side seat 103 is installed with a rocker arm 106 for easy holding. Preferably, the rocker arm 106 is L-shaped. With this arrangement, it is convenient to drive the screw 105 to rotate effortlessly by holding the rocker arm 106. The roller 109 is sleeved on the outer periphery of the screw 105 in a coaxial sliding fit manner. The parts of the screw 105 extending out of the two ends of the roller 109 are coaxially engaged with the limit nuts 108, and the limit nuts 108 are pressed against the surface of the end plate 102. With this arrangement, it is convenient to smoothly combine and fix the roller 109 on the outer periphery of the screw 105 by pressing the limit nuts 108 on both sides against the surface of the roller 109.

[0040] See also Figure 1-Figure 6 As shown, a plurality of connecting rods 101 are fixedly connected between the tops of the side seats 103 at both sides, so that the side seats 103 at both sides can be connected as a whole through the setting of the connecting rods 101. The outer diameter of the end plate 102 is at least 1.5 times the outer diameter of the drum 109. Such a setting facilitates the end plate 102 to have a sufficiently large diameter to prevent the cable 401 from escaping from the edge of the drum 109 during the winding process. A wire passing opening 201 is provided in the middle of the top plate 2, and the wire passing opening 201 is located below the drum 109. Preferably, the wire passing opening 201 is a waist-shaped hole style, and the lateral length of the wire passing opening 201 is not less than the axial length of the drum 109, as shown in FIG. This arrangement makes it possible for the wire opening 201 to have a sufficiently large size so that the cable 401 can be smoothly lowered and reeled. The bottom surface of the vertical plate 3 is horizontally extended and fixed with a connecting plate 302 for fixing to the ground. Preferably, through holes are provided at the four corners of the connecting plate 302 so that the top plate 2 and the vertical plate 3 can be temporarily fixed by inserting anchor rods into the ground through the through holes of the connecting plate 302. The vertical plates 3 on both sides are installed with lifting handles 301 for easy handholding in the middle of the outer sides facing each other. This arrangement makes it easy to lift the top plate 2, the vertical plate 3, the retractable assembly 1 and the inclination deformation monitoring assembly 4 by applying force with the lifting handles 301.

[0041] Further optionally, the outer surface of the cable 401 is printed with scale marks 402 for indicating the length. This arrangement makes it easy to lower the inclinometer probe body 403 to a specified depth of the monitoring well by referring to the scale marks 402 during the process of lowering the inclinometer probe body 403, and to lock the lowering position height of the inclinometer probe body 403 by tightening the locking nut 104 to press it against the surface of the side seat 103. The horizontal cross-section shapes of the matching seat 504, the through-slot 506 and the matching groove 505 are all rectangular, so that the matching seat 504 and the matching groove 505 can be locked. The mating groove 505 and the through-slot 506 have good positioning and guiding designs when they are vertically slidably matched. The bottom surface of the side seat 103 cannot pass through the corresponding through-slot 506, and the bottom surface of the side seat 103 is in close contact with the top surface of the top plate 2. This arrangement makes it easy for the mating seat 504 to slide vertically along the through-slot 506 and the mating groove 505. When the mating seat 504 moves to the limit hole 509 and is coaxial with the corresponding limit rod 508, an obvious prompt can be given by the bottom surface of the side seat 103 being in close contact with the top surface of the top plate 2.

[0042] When the above structure is adopted, specifically when the deformation of the foundation soil is monitored, since the matching seat 504 initially passes through the through-slot 506 and vertically slides with the matching slot 505, and the limiting rod 508 and the limiting hole 509 slide horizontally, the matching seat 504 can be locked and cannot escape from the matching slot 505 through the matching restriction of the limiting rod 508 and the limiting hole 509. At this time, the retractable assembly 1 and the inclinometric deformation monitoring assembly 4 are detachably fixed to the top of the top plate 2. The fixing combination of the retractable assembly 1 and the inclinometric deformation monitoring assembly 4 and the top plate 2 is simple and easy to operate, which makes it easy to quickly fix the retractable assembly 1 and the inclinometric deformation monitoring assembly 4 on the top of the top plate 2 for soil deformation monitoring. When in use, lift the handle 30 1 Move the top plate 2 to the monitoring well at the monitoring position and let the vertical plates 3 stand on both sides of the monitoring well respectively. At the same time, the inclinometer probe body 403 should be suspended above the monitoring well. Then, after loosening the locking nut 104, the cable 401 wound around the outer periphery of the drum 109 can be rolled up or released by driving the roller 109 to rotate forward and reversely through the screw 105. Then, during monitoring, the cable 401 can be released by the drum 109 rotating forward clockwise and driving the inclinometer probe body 403 to be lowered into the monitoring well. At the same time, since the surface of the cable 401 is printed with scale marks 402, the inclinometer probe body 403 can be lowered to the specified depth of the monitoring well by referring to the scale marks 402 during the process of lowering the inclinometer probe body 403. The height of the lowered position of the inclinometer probe body 403 is locked by tightening the locking nut 104 and pressing it against the surface of the side seat 103. Specifically, when referring to it, first observe the scale value when the scale mark 402 is level with the top surface of the top plate 2 when the inclinometer probe body 403 is lowered to the bottom and is level with the top of the wellhead of the monitoring well. Then, based on this scale value, lower the cable 401 until the increased scale number is consistent with the specified depth of the inclinometer probe body 403 in the monitoring well. After the inclinometer probe body 403 reaches the specified depth, stop releasing the cable 401 and tighten the locking nut 104. Then, operate the controller 404 and adjust the inclinometer probe body 403 to the specified depth of the monitoring well by wireless communication with the wireless signal transceiver 405. The inclination of the soil is measured with a certain degree, so as to realize the inclinometer probe body 403 to monitor the inclinometer deformation of the soil at the specified depth of the monitoring well, and the inclinometer probe body 403 can be stably maintained at the specified depth in the monitoring well for a long time, and at the same time, it replaces the operation mode of personnel holding the cable 401 to apply force to lower and pull up the inclinometer probe body 403, which reduces the work intensity and is conducive to improving the accuracy and efficiency of the monitoring process. When the measurement is completed, the locking nut 104 is loosened and the roller 109 is reversed counterclockwise to rewind the cable 401. At the same time, during the process of the cable 401 being rewound, the inclinometer probe body 403 rises and leaves the monitoring well, and then the top plate 2 can be lifted and transferred to the next monitoring well to monitor the inclinometer deformation of the soil again. After the subsequent use is completed,Only by pulling the limit rod 508 out of the limit hole 509, the matching seat 504 can be vertically disengaged from the matching groove 505 and the insertion slot 506 in sequence to remove the retractable assembly 1 and the inclination deformation monitoring assembly 4 from the top plate 2. The separation method of the retractable assembly 1 and the inclination deformation monitoring assembly 4 from the top plate 2 is simple and easy to operate, which is convenient for the retractable assembly 1 and the inclination deformation monitoring assembly 4 to be quickly removed from the top plate 2 for regular inspection and maintenance in the later stage, and is also conducive to improving the flexibility of the retractable assembly 1 and the inclination deformation monitoring assembly 4 when using.
