Description

Technical Field

[0001] This utility model belongs to the field of grout leakage detection technology, specifically relating to a grout leakage detection device for water conservancy supervision. Background Technology

[0002] The purpose of grout leakage detection in water conservancy supervision is to monitor unexpected leakage of grout during grouting construction, with the core objective of ensuring the integrity of the grout body and its seepage prevention effect. Grout leakage problems are mainly caused by geological defects (such as karst fissures and fault fracture zones), excessive grouting pressure (exceeding the rock strata's splitting pressure), inadequate sealing of the orifice, or excessive grout fluidity. If not detected and controlled in time, it can lead to risks such as large-scale grout loss (wasting materials), discontinuity of the grouting curtain (forming leakage channels), and even rock mass uplift and deformation.

[0003] A Chinese utility model patent with publication number CN213120974U discloses a grout leakage detection device for water conservancy supervision, including a base plate and a foam suspension element. A supporting plate is provided on the base plate, and a first plate is fixedly connected to the supporting plate. The first plate is parallel to the base plate and has a first guide hole. The foam suspension element includes a cylindrical base and a cylindrical rod is fixedly connected to the cylindrical base. When detecting grout leakage, the base plate is fixed to the ground, and the cylindrical rod is slidably inserted into the first guide hole. The cylindrical base floats on the surface of the grout liquid and floats with the change of the grout liquid level, driving the cylindrical rod to move. It can be used to detect whether there is hidden grout leakage underground.

[0004] Currently, grouting typically involves drilling grouting holes in the ground, resulting in significant vertical depths. In the aforementioned comparative document, a cylindrical rod connected to a cylindrical base is used, but its effective measuring range is short. During grouting, if leakage occurs, the grout seeps downwards, easily exceeding the measuring range of the cylindrical rod, causing measurement failure. Furthermore, the cylindrical rod cannot be too long, otherwise its own weight would exceed the buoyancy of the cylindrical base. In reality, during grouting, as the grout seeps downwards, some water in the grout separates and seeps out, causing the grout level to drop. However, this usually stops quickly, even when the underground cavity is small. The leakage will also stop quickly, but it easily exceeds the measuring range of the cylindrical rod, making it impossible to effectively determine whether the leakage has stopped or continues. It cannot measure the final stopping depth of the liquid level after leakage. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a grout leakage detection device for water conservancy supervision. This solves the problem that currently, during grouting, grouting holes are typically drilled in the ground, resulting in significant vertical depths. In the aforementioned comparative documents, a cylindrical rod connected to a cylindrical base has a short effective measuring range. During grouting, if leakage occurs, the grout seeps downwards, easily exceeding the measuring range of the cylindrical rod, causing measurement failure. Furthermore, the cylindrical rod cannot be too long, otherwise its own weight would exceed the buoyancy of the cylindrical base. In reality, during grouting, as the grout seeps downwards, some water in the grout separates and seeps out, causing the grout level to drop. However, this drop usually stops quickly, even when the underground cavity is small. The leakage phenomenon also stops quickly, but it easily exceeds the measuring range of the cylindrical rod, making it impossible to effectively determine whether the leakage has stopped or continues, and it cannot measure the final stopping depth of the liquid level after leakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a grout leakage detection device for water conservancy supervision, comprising parallel foot rods, each foot rod having a vertical rod fixedly installed at the upper middle part of its upper side, a horizontal rod fixedly installed at the upper end of each vertical rod, a fixing ring fixedly installed at one end of each horizontal rod close to the other, a side plate fixedly installed on one side of each horizontal rod, an electric wire feeder fixedly installed on the upper side of the side plate, a connecting wire wound around the output area of ​​the electric wire feeder, the connecting wire passing downward through the fixing ring and being connected to a floating mechanism, the floating mechanism including a connecting rod, a tethering ring, a foam float, a protective shell and an electronic display light, a tethering ring fixedly installed at the upper end of the connecting rod, the connecting wire being connected to the tethering ring, and a foam float fixedly installed on the lower side of the connecting rod.

[0007] The beneficial effects of this utility model are as follows: the measurement range of this technical solution is very long, which can continuously track the slurry surface. By observing whether the connecting line is continuously released, it is possible to intuitively and effectively determine whether the slurry leakage has stopped or continues. By measuring the length of the released connecting line, the final termination depth of the liquid surface can be calculated.

[0008] In order to count the connecting wires;

[0009] As a further improvement to the above technical solution: a wheel counter is rotatably mounted on the upper side of the crossbar near the fixed ring, which is connected to the electric wire feeder, and the connecting line is tightly connected to the wheel counter.

[0010] The beneficial effects of this improvement are as follows: When the connecting wire is unloaded, it will drive the wheel counter to rotate, and the wheel counter can count the unloaded wire. The contact surface between the wheel counter and the connecting wire can be made tight by rubber rings, etc., so that the connecting wire and the wheel counter are less likely to slip, and the accuracy of the wheel counter measurement is increased.

[0011] To increase the stability of this device;

[0012] As a further improvement to the above technical solution: anti-slip cones are uniformly fixedly provided on the lower side of the foot rod.

[0013] The beneficial effect of this improvement is that it increases the stability of the device when placed.

[0014] To adjust the height of the crossbar and retaining ring;

[0015] As a further improvement to the above technical solution: the upright is composed of a base rod and an extension rod. The base rod is fixed on the upper side of the foot rod, and the extension rod is inserted and set on the upper side of the base rod. The upper end of the extension rod is fixedly connected to the crossbar. A knob is threaded on the upper side of one side of the base rod, and the knob threaded through the base rod and pressed against the extension rod.

[0016] The beneficial effects of this improvement are: the extension rod is stretched upwards and pressed and fixed by a knob, which makes it easy to adjust the height of the crossbar and the fixing ring according to the height position of the grouting port.

[0017] For use in protecting foam floats;

[0018] As a further improvement to the above technical solution: a protective shell is provided on the lower side of the foam float.

[0019] The beneficial effects of this improvement are: a protective shell is set up to protect the foam float, and the foam float can be made of a material that is easy to clean, making it easy to clean afterwards.

[0020] To increase the tightness of the protective shell on the outside of the foam float and to facilitate the disassembly and replacement of the foam float;

[0021] As a further improvement to the above technical solution: the lower end of the connecting rod passes through the foam float and is threadedly connected to the center of the protective shell.

[0022] The beneficial effects of this improvement are: the connecting rod passes through the foam float and is threaded to the protective shell, increasing the tightness of the protective shell on the outside of the foam float and facilitating the disassembly and replacement of the foam float.

[0023] In order to observe the position of the floating mechanism;

[0024] As a further improvement to the above technical solution: an electronic indicator light is sleeved on the outer side of the connecting rod.

[0025] The beneficial effects of this improvement are as follows: an electronic indicator light is installed. The electronic indicator light can be a frequency-flash electronic light with a built-in battery box, which is powered by a battery or electricity. When in use, it is turned on, making it easy to observe the position of the floating mechanism with the naked eye when the floating mechanism sinks with the paddle surface.

A foam float 53 is fixedly installed on the lower side of the connecting rod 51. This technical solution has a long measuring range and can continuously track the slurry surface. By observing whether the connecting line 7 is continuously released, it is possible to intuitively and effectively determine whether the slurry leakage has stopped or continues. By measuring the length of the released connecting line 7, the final termination depth of the liquid surface can be calculated. A wheel counter 8 is rotatably installed on the upper side of the crossbar 3 near the fixed ring 4, which is connected to the electric wire release device 6. The connecting line 7 is tightly connected to the wheel counter 8. When the connecting line 7 is released, it will drive the wheel counter 8 to rotate. The wheel counter 8 can count the connecting line 7. The contact surface between the wheel counter 8 and the connecting line 7 can be made of rubber rings, etc., so that the wheel counter counts. The device 8 and connecting line 7 are tightly connected, making it less prone to slippage between the connecting line 7 and the wheel counter 8, thus increasing the accuracy of the wheel counter 8's measurement.

The base rod is fixed to the upper side of the foot rod 1, and the extension rod is inserted into the upper side of the base rod.

It is turned on during use to facilitate visual observation of the position of the floating mechanism 5 as it sinks with the paddle surface.

[0034] Working principle and usage process of this utility model:

[0035] In use, the device is placed on the upper side of the grouting hole, and the floating mechanism 5 is lowered into the grouting hole. After grouting, the floating mechanism 5 will float on the grout surface through the foam float 53. When the grout surface drops, the foam float 53 will drop along with the grout surface. When the floating mechanism 5 drops, it will pull the connecting line 7 out from the electric wire feeder 6. As the grout surface continues to drop, the connecting line 7 will continue to be released. When the grout surface stops dropping, the electric wire feeder 6 will stop releasing the connecting line 7. Compared with the prior art, the range of this technical solution is very long, which can continuously track the grout surface. By whether the connecting line 7 is continuously released, it is possible to intuitively and effectively determine whether the grout leakage has stopped or continues. By measuring the length of the released connecting line 7, the final termination depth of the grout surface can be calculated. In addition, a wheel counter 8 is rotatably mounted on the upper side of the crossbar 3 near the fixed ring 4, which is connected to the electric wire feeder 6. The connecting line 7 is tightly connected to the wheel counter 8. When the connecting line 7 feeds the wire, it drives the wheel counter 8 to rotate, and the wheel counter 8 can count the connecting line 7. The contact surface between the wheel counter 8 and the connecting line 7 can be made tightly connected by rubber rings, etc., so that the connecting line 7 and the wheel counter 8 are not prone to slippage, thus increasing the accuracy of the wheel counter 8. In addition, anti-slip cones 9 are evenly fixed on the lower side of the foot rod 1 to increase the stability of the device. Furthermore, the extension rod is extended upwards, and the extension rod can be adjusted by a knob. The crossbar 3 and the fixing ring 4 are pressed and fixed to facilitate the adjustment of their heights according to the height of the grouting port. In addition, a protective shell 54 is provided to protect the foam float 53. The foam float 53 can be made of a material that is easy to clean, making it convenient for post-cleaning. Furthermore, the connecting rod 51 passes through the foam float 53 and is threadedly connected to the protective shell 54, increasing the tightness of the protective shell 54 on the outside of the foam float 53 and facilitating the disassembly and replacement of the foam float 53. In addition, an electronic indicator light 55 is provided. The electronic indicator light 55 can be a frequency flash electronic light with a built-in battery box, powered by batteries or electronics. It is turned on during use to facilitate visual observation of the position of the floating mechanism 5 when it sinks with the grout surface.
