Description

Technical Field

[0001] This utility model belongs to the field of engineering monitoring technology, specifically relating to a seepage monitoring device for building foundation pit construction. Background Technology

[0002] An excavation pit is the space below ground level excavated for the construction of a building's foundation and basement. During the use of an excavation pit, it is necessary to monitor for water seepage and maintain the seepage points in a timely manner to prevent safety accidents.

[0003] Chinese patent CN219978278U discloses a seepage monitoring device for a hydroelectric power station dam. The device includes a support column and a base that can slide laterally relative to the support column. A water collection tank is vertically slidable inside the base. A switch is installed in a groove at the lower end of the base, and an indicator light is installed at the top of the support column. The device uses a water-absorbing strip at the upper end of the water collection tank to press against the dam to collect water in the tank. The weight of the water inside the tank causes it to fall, triggering the switch in the groove and illuminating the indicator light to alert the monitoring personnel to the presence of seepage.

[0004] With adjustments to the installation method, the above solution can also be used to monitor water seepage on the sidewalls of the foundation pit. However, in order for the water-absorbing strip to collect the water from the sidewalls of the foundation pit, it needs to be pressed tightly against the sidewalls. But the sidewalls of the foundation pit are usually quite rough, and the friction between the water-absorbing strip and the sidewalls will prevent the water collection tank from moving downwards, making the above solution unsuitable for situations where the sidewalls are rough. Utility Model Content

[0005] The present invention aims to provide a seepage monitoring device for building foundation pit construction, in order to solve the problem that the above-mentioned solutions are not applicable to situations with relatively rough sidewalls.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A seepage monitoring device for building foundation pit construction includes a support column, a first telescopic rod, a water collection box, an indicator light, and a liquid level sensor. A support plate is fixedly installed at the bottom of the support column. The first telescopic rod is horizontally installed at the top of the support column. The water collection box is vertically installed to the right of the first telescopic rod. The water collection box has an inner cavity, and an opening extending to the side wall of the water collection box is provided at the top right side of the inner cavity. A U-shaped rubber strip is provided outside the opening on the right side wall of the water collection box. The indicator light is fixedly installed at the top of the water collection box. The liquid level sensor is fixedly installed at the front of the water collection box and is electrically connected to the controller of the indicator light.

[0008] The principle and effects of this technical solution:

[0009] Place the support plate on the ground to fix the support column, extend the first telescopic rod so that the rubber strip on the right side of the water collection box is tightly attached to the joint of the pit side wall. When water seepage occurs in the pit, the rubber strip guides the water from the opening and above it into the inner cavity. When the liquid level sensor senses that the water level in the inner cavity has risen to a certain height, it triggers the indicator light to flash to issue a warning.

[0010] By using the above setup, water is collected from the sidewalls of the foundation pit using a water collection box, and a liquid level sensor detects the water level in the collection box, triggering an indicator light to warn the inspectors. This solves the problem that the above solution is not applicable to situations with relatively rough sidewalls.

[0011] In this invention, the first telescopic rod includes a sleeve rod and a crossbar. A threaded rod is rotatably inserted into the left end of the sleeve rod, and the left end of the crossbar is slidably inserted into the right end of the sleeve rod and fitted onto the threaded rod. A motor is fixedly installed on the left side wall of the sleeve rod, and the output shaft of the motor is connected to the threaded rod for transmission. Through the above arrangement, the purpose of making the water collection box tightly adhere to the side wall of the foundation pit is achieved.

[0012] In this invention, a plurality of drill rods are slidably inserted through the top of the support plate.

[0013] In this utility model, the left end of the sleeve rod is rotatably connected to the top of the support column, and the construction pit seepage monitoring device further includes a second telescopic rod, the two ends of which are rotatably connected to the side wall of the support column and the bottom wall of the sleeve rod, respectively.

[0014] In this invention, the second telescopic rod is configured as a hydraulic push rod.

[0015] The principle and effects of this technical solution:

[0016] When the ground is sloping or has large potholes, place the support plate on the ground and insert multiple rods through the top of the support plate to fix it in place. Then adjust the length of the second telescopic rod to keep the first telescopic rod horizontal.

[0017] With the above setup, the support plate can be fixed on sloping or uneven ground, while the first telescopic rod can be kept horizontal, thereby ensuring that the rubber strip can abut against the side wall of the pit and improve water collection efficiency.

[0018] In this utility model, a sleeve is fixedly provided at the right end of the crossbar, and a groove is recessed on the right side of the sleeve. A connecting block is fixedly provided at the left end of the water collection box. The connecting block is slidably inserted into the groove, and a compression spring is provided between the connecting block and the end wall of the groove.

[0019] The principle and effects of this technical solution:

[0020] After extending the first telescopic rod to make the water collection box fit tightly against the side wall of the pit, continue extending the first telescopic rod to compress the connecting block spring, which has elastic force.

[0021] The above-mentioned design avoids the water collection box failing to fit tightly against the side of the pit due to loose threaded rods during the monitoring process, thus improving the practicality of this invention.

[0022] In this invention, a through groove extending to the top of the sleeve is provided at the top of the chute, and a limiting block is fixedly provided on the left side of the top of the connecting block, the limiting block being slidably embedded in the through groove. This design prevents the water collection box from separating from the first telescopic rod during transport, thus improving the practicality of this invention.

[0023] In this invention, a funnel-shaped groove is provided at the bottom of the inner cavity, and a water collection chamber is provided at the bottom of the groove near the liquid level sensor. The projected area of ​​the water collection chamber is much smaller than the projected area of ​​the inner cavity. This design accelerates the rate of water level increase in the collection box and shortens the response time of this invention.

[0024] In this invention, a through hole is provided at the bottom of the water collection chamber, and a plug is threaded into the through hole at the bottom of the water collection box. This design allows inspectors to easily drain the water from the collection box after repairing the seepage point, enabling repeated use of the invention and improving its utilization rate.
