DETAILED DESCRIPTION

[0027] The preferred embodiments of the present application will be described below in conjunction with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and do not limit the present application.

[0028] Embodiment: as Figure 1 , Figure 4 and Figure 5As shown, the deep foundation pit diaphragm wall deep horizontal displacement monitoring device comprises a supporting device, a monitoring device and a carrier, the carrier is arranged on the supporting device, the monitoring device is arranged in the carrier, is used for measuring the slope generated by the horizontal displacement of the deep foundation pit extruding the diaphragm wall, further comprises an adjusting part, a height adjusting part and a damping part, the adjusting part is arranged on the supporting device and is connected with the carrier, is used for driving the carrier to move on the supporting device, the height adjusting part is arranged in the carrier and is connected with the monitoring device, is used for driving the monitoring device to move in the carrier; the damping part is arranged on the carrier and is used for supporting the carrier.

[0029] By adjusting the part and the damping part, the device can be installed and arranged according to the actual "deep foundation pit diaphragm wall deep" to be monitored, that is, if the to-be-monitored place has a left slight inclination, a vertical state or a right slight inclination, the device can be arranged to fit the situation Figure 4 and Figure 5 As shown;

[0030] The damping part is a gas strut 14, the bottom end of the gas strut 14 is rotatably connected with a supporting plate 15, the supporting plate 15 is integrally connected with the adapter seat 13, and the telescopic end of the gas strut 14 is rotatably connected with the inclinometer tube 5.

[0031] The damping part can ensure that the carrier is vertical or inclined on the supporting device, and can be inclined with the compression force when subjected to displacement compression.

[0032] By changing the height of the device for measuring the slope on the carrier through the height adjusting part, the construction personnel can perform real-time monitoring of the deep foundation pit diaphragm wall deep horizontal displacement at different positions, different depths and various stages, and thus the monitoring data can be collected, which is helpful for correctly guiding the deep foundation pit earthwork construction.

[0033] Specifically as follows:

[0034] The device is arranged at the inner side of the deep foundation pit diaphragm wall, after being arranged, the monitoring device is turned on, and thus the soil mechanical properties and the deformation of the surrounding soil of the foundation pit caused in the construction process can be monitored in real time at different positions, and the monitoring results can be obtained in time, the precursors of possible dangers can be found, the safety of the project can be judged, and the occurrence of engineering damage accidents can be prevented

[0035] The supporting device comprises a cement seat 1 and a plug-in seat 2 arranged outside the top of the cement seat 1, the plug-in seat 2 is installed and connected with the monitoring device and the carrier.

[0036] The cement seat 1 can position the lower half of the device not to move with the horizontal displacement generated by the deformation of the surrounding soil of the foundation pit, and the upper part of the cement seat 1 will move.

[0037] A display device 3 is embedded on one side of the plug-in seat 2, the monitoring device is signal connected with the display device 3, and the display device 3 is used for receiving the slope data generated by the horizontal displacement of the deep foundation pit extruding the diaphragm wall.

[0038] Because the monitoring device is located in a part that can move with the horizontal displacement caused by the deformation of the soil around the foundation pit, the monitoring device can detect and measure the inclination caused by the horizontal displacement of the deep foundation pit squeezing the diaphragm wall, and transmit the value to the display device or the terminal connected to the external signal. By viewing the monitoring data, the device can detect the early signs of potential danger, judge the safety of the project, and prevent the occurrence of project damage accidents.

[0039] An elastic rubber sleeve 4 can be connected between the top of the plug-in 2 and the bottom of the carrier. The elastic rubber sleeve 4 is used to cover the soil and debris.

[0040] Because the upper part of the device and the lower positioning part cement seat 1 are connected by a transmission structure, the insertion seat 2 on the cement seat 1 has a groove. The elastic rubber sleeve 4 prevents soil from entering the cement seat 1 without hindering the movement of the upper part of the device, allowing it to deform under stress. (See...) Figure 4 and Figure 5 The effect shown in the deformation.

[0041] Example: Figure 2 As shown, the deep horizontal displacement monitoring device for diaphragm walls in deep foundation pits of the present invention uses an inclinometer tube 5 as its carrier. A partition 6 is provided in the middle of the inclinometer tube 5, dividing the inclinometer tube 5 into a left installation area and a right lifting area via the partition 6. A height adjustment component is located in the left installation area, and one side of the component extends through the partition 6 into the right lifting area. The monitoring device is located on the portion of the height adjustment component within the right lifting area. A thickened portion 12 is provided on the side of the inclinometer tube 5 adjacent to the monitoring device. The structural design of the inclinometer tube 5 allows it to support the height adjustment component and the monitoring device. When the inclinometer tube 5 is positioned on one side of the connector 2, it protrudes from the connector 2, thus allowing it to contact the surface to be monitored without obstruction from the connector 2.

[0042] By increasing the height of the device that changes the measuring inclination on the carrier, construction personnel can monitor the deep horizontal displacement of the diaphragm wall in deep foundation pits in real time at different locations, depths, and stages. The specific structure is as follows:

[0043] The height adjustment component includes a screw 7 rotatably connected in the left installation area and a handwheel 8 for driving the screw 7 to rotate. The handwheel 8 is located on the carrier, and the screw 7 passes through the carrier and is connected to the handwheel 8. The handwheel 8 is externally threadedly connected to a threaded sleeve 9 and a lifting plate 10 that moves synchronously with the threaded sleeve 9. The lifting plate 10 is located in the right lifting area and passes through a limiting groove opened in the middle of the partition 6 and is connected to the threaded sleeve 9.

[0044] The monitoring device is an inclinometer 11, and the bottom of the inclinometer 11 is connected to a base. The inclinometer 11 is fixed to the lifting plate 10 through the base.

[0045] By rotating the screw rod 7 through the hand wheel 8, and under the action of the limiting sliding groove opened in the middle of the partition plate 6, the threaded sleeve 9 and the lifting plate 10 will not rotate with the screw rod 7, but under the rotation of the screw rod 7, the inclinometer 11 on the threaded sleeve 9 and the lifting plate 10 moves in the inclinometer tube 5, and through the forward and reverse rotation of the screw rod 7, the inclinometer 11 performs the lifting movement.

[0046] Embodiment: as Figure 3 indicated, the adjusting component can drive the inclinometer tube 5 to contact the diaphragm wall, and the specific structure is as follows:

[0047] The adjusting component and the height adjusting component are consistent in structure, the inside of the plug-in seat 2 is hollowed out as an installation area, a sliding groove is opened at the top and communicates with the installation area, a transition seat 13 is arranged on the sliding groove, the bottom end of the transition seat 13 is detachably connected with the threaded sleeve 9 of the adjusting component through the sliding groove, and the top is integrally connected with the inclinometer tube 5.

[0048] The inclinometer tube 5 is horizontally moved on the plug-in seat 2 in the same driving mode as the height adjusting component, so that the inclinometer tube 5 contacts the diaphragm wall.

[0049] Supplementary explanation: the deep foundation pit refers to the depth of the foundation pit excavation exceeding 5 meters, and also includes 5 meters, which is a deep foundation pit in this case;

[0050] The diaphragm wall in the deep foundation pit is a very important part in engineering construction: the deep foundation pit supporting component - the underground continuous wall, in simple terms, is a circle of enclosing wall cast on the inner side wall of a deep foundation pit;

[0051] The deep foundation pit will generate a horizontal displacement force (which can be understood as a landslide phenomenon, which occurs when the supporting force of the inner side supporting diaphragm wall is less than the horizontal displacement force of the deep foundation pit), and the displacement force applied to the diaphragm wall will cause the part above the base to incline, and the device obtains the horizontal displacement data by detecting the inclination value.

[0052] In the description of the present application, it should be noted that the terms "vertical", "upper", "lower", "horizontal" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application.

[0053] In the description of the application, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "install", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
