Description

Technical Field

[0001] The utility model relates to the field of monitoring the water level in a foundation pit dewatering well, and specifically to a water level monitoring device for a dewatering well. Background Art

[0002] If the water level at the construction site is too high and affects the normal construction of the project, dewatering work within the construction area must be carried out. Well point dewatering is one of the most commonly used dewatering methods. The foundation pit excavation can only be carried out when the groundwater level is lowered to 0.5 - 1.5 m below the excavation surface, so it is particularly important to observe the groundwater level.

[0003] The traditional way to observe the groundwater level is to measure the distance from the wellhead to the water level in the observation well with a sounding rope, and then calculate whether the excavation conditions are met based on the measured data. The disadvantage is that it requires manual measurement of each observation well, with a large workload and slow timeliness. Therefore, in view of the above disadvantages, it is necessary to improve the way of observing the groundwater level. Summary of the Invention

[0004] The utility model provides a water level monitoring device for a dewatering well to solve the problems that when observing the groundwater level, it is necessary to manually measure each observation well, with a large workload and slow timeliness.

[0005] The utility model is realized through the following technical solutions: A water level monitoring device for a dewatering well includes a buoyancy chamber structure, a scale structure, and an installation structure. The buoyancy chamber structure includes a buoyancy chamber outer shell. The upper part inside the buoyancy chamber outer shell is an upper buoyancy chamber, and the lower part is a hollow bottom bin. The upper buoyancy chamber and the hollow bottom bin are hermetically separated by an intermediate partition. The shape of the hollow bottom bin is a cone with the tip downward, and the bottom tip of the hollow bottom bin is filled with stable counterweight sand. The middle part of the upper buoyancy chamber is cylindrical, and the upper part is a cone with the tip upward. A vertical downward scale bolt hole is opened at the upper tip of the upper buoyancy chamber. The scale structure includes a scale rod. Red and green scale color marking layers are provided on the outer wall of the scale rod, with the upper part being green and the lower part being red. The bottom end of the scale rod is fixedly connected with a scale fixing bolt, and the scale fixing bolt is threadedly connected into the scale bolt hole. A marking flagpole and a marking flag are also detachably connected to the top end of the scale rod. The installation structure includes a scale rod fixing piece. The scale rod fixing piece is installed at the top end of the dewatering well sand pipe. A scale rod fixing hole is opened in the middle of the scale rod fixing piece, and the scale rod is sleeved outside through this hole. The buoyancy chamber structure and the scale structure both extend into the dewatering well sand pipe.

[0006] A water level monitoring device for precipitation wells designed by the utility model is used in areas with accumulated water and is designed to monitor the water level. The device includes a buoyancy chamber structure, a scale structure, and a mounting structure. The buoyancy chamber structure includes a buoyancy chamber housing. The upper part inside the buoyancy chamber housing is the upper buoyancy chamber, ensuring that the entire buoyancy chamber structure can float on the water surface. The lower part inside the buoyancy chamber housing is a hollow bottom bin. The upper buoyancy chamber and the hollow bottom bin are sealed and separated by an intermediate partition. The shape of the hollow bottom bin is a cone with the tip pointing downward, and the bottom tip of the hollow bottom bin is filled with stable counterweight sand. The intermediate partition can prevent the stable counterweight sand from running into the upper buoyancy chamber, resulting in the instability of the buoyancy chamber structure. The middle part of the upper buoyancy chamber is cylindrical, and the upper part is a cone with the tip pointing upward. A vertical downward scale bolt hole is opened at the upper tip of the upper buoyancy chamber for connecting the scale rod. The scale structure includes a scale rod. Red and green scale color marking layers are provided on the outer wall of the scale rod. The upper part is red, and the lower part is green, used for staff to observe whether it is in a safe state. Green represents safety, and red represents danger. The bottom end of the scale rod is fixedly connected with a scale fixing bolt, and the scale fixing bolt is threadedly connected into the scale bolt hole, thus connecting the scale rod and the buoyancy chamber structure into one body. A marking flagpole and a marking flag are also detachably connected to the top of the scale rod, and both the marking flagpole and the marking flag are finally installed on the scale rod. The mounting structure includes a scale rod fixing piece. The scale rod fixing piece is installed at the top of the precipitation well sand pipe. A scale rod fixing hole is opened in the middle of the scale rod fixing piece and the outer circumference of the scale rod is sleeved through this hole, so that the buoyancy chamber structure and the scale structure are installed on the precipitation well sand pipe through the scale rod fixing piece, and both the buoyancy chamber structure and the scale structure extend into the precipitation well sand pipe. The specific operation of the utility model is as follows: insert the scale fixing bolt into the scale bolt hole, rotate and tighten it, then put both the buoyancy chamber structure and the scale structure into the precipitation well sand pipe, pass the scale rod fixing piece through the scale rod through the scale rod fixing hole, so that the scale rod fixing piece is sleeved outside the scale rod, and then fixedly install the scale rod fixing piece at the top of the precipitation well sand pipe, and the whole device is installed; during the observation process, judge the current groundwater level situation according to the color marking of the exposed part of the scale rod, and determine whether earthwork excavation can be carried out; the precipitation well sand pipe has been installed in the required area in advance.

[0007] Preferably, the scale rod is a telescopic scale rod, and a number-of-sections marking is provided at its top end, so that it can be telescoped according to the well depth and adjusted to a length matching the precipitation well sand pipe.

[0008] Preferably, the scale color marking layer is also filled with a luminous agent and a fluorescent agent, so that the scale rod can be accurately identified in the absence of light or poor lighting conditions.

[0009] Compared with the prior art, the utility model has the following beneficial effects: The precipitation well water level monitoring device provided by the utility model solves the problems of large workload and slow timeliness in manually measuring each observation well; by using the buoyancy principle, adopting a floating bladder structure, adding a stable counterweight cabin to ensure its stability on the horizontal plane, installing a scale with color marks on the upper part, and a marking flag for identification, it is possible to directly understand whether earthwork excavation can be carried out without on-site measurement and calculation.
