Description

Technical Field

[0001] This utility model belongs to the field of building engineering monitoring technology, specifically relating to a monitoring device for backfill elevation of fertilizer trenches. Background Technology

[0002] A backfill trench refers to the extra section excavated to provide a working surface. Generally, it refers to the space between the outer wall of the basement or foundation of a building and the edge of the excavation pit. In construction engineering, backfilling the trench is an important step in ensuring the stability and safety of the building. The trench can be backfilled with soil or construction waste, but the backfill material needs to be compacted. The trench can also be filled with fluidized solidified soil or concrete, which does not require compaction. However, the backfill elevation needs to be measured during the backfilling process. The existing measurement method is generally manual, which is easily affected by human factors, leading to inaccurate monitoring results.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

[0024] In the description of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0026] like Figure 1 As shown, a monitoring device for monitoring the elevation of backfill trench includes a fixed rod 1, a positioning rod 3, a locking rod 5, a sliding rod 12, and a float 10. The fixed rod 1, positioning rod 3, locking rod 5, and sliding rod 12 are all high-strength metal rods, such as steel bars or steel rods. This device is installed on the exterior wall of a building's basement or foundation (generally, backfilling is carried out after the main construction of the basement is completed or after the exterior wall construction reaches 1-3m above ground level). The fixed rod 1 extends longitudinally and is tightly attached to the inner wall of the exterior wall. The upper end of the fixed rod 1 extends upwards towards the exterior wall. A horizontal bar 2 extending outwards from the upper end of the fixed rod 1 is provided, having a certain length and placed on the upper surface of the exterior wall. The positioning rod 3 is located on the outer side of the exterior wall, with its upper end slidably mounted on the horizontal bar 2. A first... A limiting member 4 is provided, thereby blocking and squeezing the outer wall of the outer wall through the first limiting member 4, thereby fixing the device to the outer wall. One end of the locking rod 5 is hinged to the lower end of the positioning rod 3, and the other end slides along the crossbar 2, so that it can be adjusted as the positioning rod 3 moves. The locking rod 5 is positioned by the second limiting member 6 to support between the positioning rod 3 and the crossbar 2, thereby ensuring the support capacity and stability of the positioning rod 3. The sliding rod 12 is set at the end of the crossbar 2 away from the outer wall, so that the position can be adjusted according to the actual position of the fertilizer tank or the detected position. The crossbar 2 extends downward in the longitudinal direction, and a marker is provided on the sliding rod 12. The elevation of the filled fluidized solidified soil is determined by the marker. The float 10 is slidably assembled on the sliding rod 12 and slides upward along the sliding rod 12 when subjected to the buoyancy of the fluidized filling material, thereby displaying the elevation of the filling material.

[0027] In an alternative embodiment, the marker is a scale line that visually displays the level of the filler.

[0028] Alternatively, the marker is a trigger switch 9, which is slidably mounted along the slide bar 12 so that its position can be adjusted according to actual needs. The trigger switch 9 is connected to a controller, which can be a PCL or a microcontroller. The controller is also connected to an alarm, which can be an audible and visual display. When the float 10 rises, it triggers the trigger switch 9 upwards. After receiving the signal from the trigger switch 9, the controller sends control information to the alarm, alerting the construction personnel through audible and visual warnings.

[0029] In an optional embodiment, the upper end of the locking rod 5 is provided with a U-shaped structure 7 corresponding to the crossbar 2. The distance between the two ends of the U-shaped structure 7 is adapted to the diameter of the crossbar 2, so that it can slide along the crossbar 2 for easy adjustment.

[0030] In an optional embodiment, both the first limiting member 4 and the second limiting member 6 are nuts, and the outer wall of the crossbar 2 is provided with external threads, so as to meet the actual limiting requirements by adjusting the threads.

[0031] The fixed rod 1 is provided with at least one support plate 11. The support plate 11 is located inside the fixed rod 1 and extends horizontally and is close to the inner wall of the outer wall, thereby forming a structure perpendicular to the crossbar 2, so that the crossbar 2 and the outer wall maintain a relative angle. In this embodiment, two support plates 11 are provided, and the two support plates 11 are located at the two ends of the fixed rod 1 respectively, so as to ensure the balance of force.

[0032] In addition, the upper end of the slide rod 12 is provided with a sliding sleeve 8 that slides along the crossbar 2. In order to limit the angle of the slide rod 12, the inner wall of the sliding sleeve 8 is a multi-faceted structure. The end of the crossbar 2 away from the fixed rod 1 is provided with a multi-faceted structure. The circumcircle of the multi-faceted structure is the circle corresponding to the cross section of the crossbar 2. The middle part of the float 10 is provided with a central hole corresponding to the slide rod 12. The diameter of the central hole is adapted to the diameter of the slide rod 12. The bottom of the slide rod 12 is provided with a stop plate corresponding to the float 10 to ensure that the float 10 will not fall downward.

[0033] 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, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
