Description
Technical Field
The utility model relates to a simple observation well water level measuring device, in particular to a measuring device for the water level of a peripheral observation well in the engineering construction precipitation stage.
Background
Precipitation before excavation of the foundation pit is very important. Whether the water level meets the design requirement can not only influence the construction safety of the earthwork excavation process, but also directly influence roads, underground pipelines and buildings in a certain peripheral range. This requires real-time grasping of the water level fluctuations in the observation wells around the pit during precipitation. The traditional water level measuring method is to gradually put the measuring rope into the observation well, and the measuring rope is a standard product with different specifications from tens meters to hundreds meters, so the device is heavy. If the water level in the observation well is deeper, the step of placing the measuring rope is that the measuring rope is repeatedly placed and received for a plurality of times, so that time and labor are wasted, and the working efficiency is reduced.
The Chinese patent with the application publication number of CN110736521A discloses a slope-mounted laser water level measuring device and method, wherein the device comprises a measuring unit, a water surface suspension reflecting ball and a measuring protection pipeline; the water surface suspending reflection ball floats on the water surface, the measuring protection pipeline is arranged on the slope, one end of the measuring protection pipeline, which is contacted with the water, wraps the water surface suspending reflection ball, and the measuring unit is arranged at the other end of the measuring protection pipeline. The structure of the method is relatively complex, and the manufacturing cost is necessarily relatively high. The method is not suitable for the construction engineering, because the construction observation well is an inevitable link in the foundation excavation precipitation stage. If the method is used for measuring the water level in the vertical well, the method is complicated and uneconomical.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a water level measuring device for an observation well, which is portable and simple to operate.
The utility model relates to an observation well water level measuring device, which comprises a measuring frame, wherein the measuring frame comprises a frame body, the frame body comprises a chassis, the chassis is formed by mutually fixing three concentric rings which are arranged at intervals inside and outside, the bottom of a supporting rod which is arranged along the vertical direction is fixed on the chassis, the upper end of the supporting rod is fixedly provided with an instrument cabin through a supporting piece, the instrument cabin comprises a c-shaped ring column, the top surface and the bottom surface of the c-shaped ring column are respectively fixed with a cover plate and a bottom plate, a light outlet hole is formed in the middle of the bottom plate, and the axis of the light outlet hole passes through the center of the concentric rings; a laser range finder is arranged in a groove of the c-shaped ring column of the instrument cabin, and a light outlet of the laser range finder is aligned with a light outlet hole of the instrument cabin bottom plate; a floating plate is arranged in the observation well, and the diameter of the floating plate is smaller than the inner diameter of the observation well by 100mm.
The utility model has the following beneficial effects:
the utility model uses laser ranging to replace the traditional ranging rope ranging, and simultaneously greatly lightens the weight of the device, and because the chassis of the device consists of three concentric rings with different diameters, the device can adapt to the observation well with most specifications at present, and any ring in the chassis is overlapped with an observation well mouth, thus completing the centering. The method has the advantages that the original water level measurement in the well which can be completed through a plurality of groups of actions is simplified into 2 actions, namely 'one-step centering' and 'one-key measurement', and the measurement efficiency is improved.

Detailed Description
The utility model is described in further detail below with reference to the drawings and examples.
As shown in the figure, the observation well water level measuring device comprises a measuring frame, wherein the measuring frame comprises a frame body 1, the frame body comprises a chassis, the chassis is formed by mutually fixing three concentric rings which are arranged at intervals inside and outside, observation wells with different diameters can be conveniently aligned, the bottom of a supporting rod which is arranged along the vertical direction is fixed on the chassis, an instrument cabin 2 is fixed at the upper end of the supporting rod through a supporting piece, the instrument cabin comprises a c-shaped ring column, a cover plate and a bottom plate are respectively fixed on the top surface and the bottom surface of the c-shaped ring column, a light outlet hole is formed in the middle of the bottom plate, and the axis of the light outlet hole passes through the center of the concentric rings; a laser range finder 3 is arranged in a groove of the c-shaped ring column of the instrument cabin, a light outlet of the laser range finder is aligned with a light outlet hole of a bottom plate of the instrument cabin, and a screw is connected to the side wall of the instrument cabin to clamp the laser range finder; a floatation plate 5 is placed in the observation well 6, the diameter of which is smaller than the inner diameter of the observation well by 100mm.
The measurement process adopting the structure is as follows:
the measuring frame carrying the laser range finder 3 is placed on the top surface of the observation well, a certain circular ring of the chassis is overlapped with the wellhead, the light outlet of the laser range finder is aligned with the center of the floating plate, the laser range finder is started, and the distance from the lower surface of the instrument cabin to the upper surface of the floating plate is measured through the range finder and is recorded as h. Then the water level elevation H2 in the observation well can be calculated through a formula, wherein H2 = H1- (H-H2) -H3, H2 is the vertical distance from the lower surface of the instrument cabin to the upper surface of the observation well head, H3 is the thickness of the floating plate, and H1 is the elevation of the observation well head. Through inspection of the measuring device, the measuring device is simple, convenient and efficient, and the time and labor for measuring the water level can be greatly reduced.
