[0002] Urease-induced carbonate precipitation (EICP) technology is mainly used to reinforce sand and rock mass to improve the mechanical properties of rock-soil body.

[0028] The present application provides a water concrete water permeation measuring device to solve the problems in the prior art and make the water permeation measurement in the crack depth direction accurate.

[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be described in further detail below with reference to the drawings and specific embodiments.

[0030] As Figures 1-4As shown, the utility model provides a kind of hydraulic concrete water permeation measuring device, including sealing sleeve 9, water seepage chamber 10, water delivery device and water reservoir 11, and the opposite two sides of sealing sleeve 9 are respectively provided with first opening and second opening, sealing sleeve 9 is used to be set in the outside of the block 8 to be tested and make first opening and second opening distribute along the depth direction of crack 81, and the inner wall of sealing sleeve 9 is attached with the outside of the block to be tested, water seepage chamber 10 includes the first chamber 101 and the second chamber 102 of intercommunication, first chamber 101 and second chamber 102 distribute along the depth direction of crack 81, sealing sleeve 9 is placed in second chamber 102, and the top and bottom of sealing sleeve 9 are attached with the top and bottom of second chamber 102, first opening is communicated with first chamber 101, first chamber 101 is connected with water delivery device, second opening is connected with water reservoir 11, and water reservoir 11 is used to contain the water that seeps out through crack 81. By sealing sleeve 9 wrapping the block 8 to be tested, and setting opening in the depth direction of crack 81 two sides, water seeping from crack 81 can be effectively guided and collected, the precise measurement of the water permeation of crack 81 is realized, and first chamber 101 can simulate the water source condition of dam side, and the simulation recovery degree is high, and the measurement precision of water permeation can be improved to a certain extent. Moreover, sealing sleeve 9 is placed in the second chamber 102 of water seepage chamber 10, and its top and bottom are attached with the top and bottom of second chamber 102, which can effectively prevent water from leaking from other positions, ensure the accuracy of water permeation measurement during measurement process, and avoid external factors interference.

[0031] In some embodiments, water seepage chamber 10 further includes third chamber 103, third chamber 103 is communicated with second chamber 102, water reservoir 11 is arranged below water seepage chamber 10, and third chamber 103 is communicated with water reservoir 11. Specifically, the bottom of third chamber is provided with opening, and the opening is communicated with water reservoir 11, third chamber 103 is arranged on the side of second chamber 102 away from first chamber 101, and the water seeping from the inside of block 8 to be tested flows into water reservoir 11 below third chamber 103 after passing through third chamber 103, and the water flow route is clear, and third chamber 103 is directly communicated with water reservoir 11, so that clogging is not easy to occur.

[0032] In some embodiments, the bottom of the second chamber 102 is vertically provided with a first vertical plate 13 and a second vertical plate 14 parallel to each other, the first vertical plate 13 and the second vertical plate 14 are arranged along a direction perpendicular to the depth of the crack 81, and the clamping space of the first vertical plate 13 and the second vertical plate 14 can clamp the sealing sleeve 9, and the first vertical plate and the second vertical plate do not cover the crack 81. The clamping space of the first vertical plate 13 and the second vertical plate 14 provides guidance and positioning for the sealing sleeve 9, and when the sealing sleeve 9 is placed, it can ensure that the sealing sleeve 9 is in the correct position in the second chamber 102, ensuring the sealing and measurement accuracy of the measuring device. Through the clamping of the first vertical plate and the second vertical plate, the sealing sleeve 9 can be stably fixed at a specific position during the measurement process, effectively preventing displacement or shaking of the sealing sleeve 9 due to water flow impact, device vibration and other factors. Moreover, the clamping of the first vertical plate and the second vertical plate can exert a certain extrusion effect on the sealing sleeve 9, making the contact surface of the sealing sleeve 9 with the vertical plate and the chamber more compact, enhancing the sealing effect, effectively preventing water leakage from the gap between the sealing sleeve 9 and the chamber, ensuring that all seepage water flows along the designed path, and improving the accuracy of seepage water measurement.

[0033] In some embodiments, the top of the first vertical plate 13 is provided with an inclined surface that slopes downward from the edge of the second chamber 102 to the direction of the third chamber 103. The inclined surface can guide the water flow entering the third chamber 103 from the second opening, making it flow more smoothly to the third chamber 103. The water flow flows along the direction of the inclined surface, improving the transmission efficiency of the water flow, which helps to more accurately measure the amount of seepage water. The design of the inclined surface can produce a one-way guiding effect on the water flow, making the water flow more inclined to flow to the third chamber 103, rather than flowing in other directions or returning to the second chamber 102, ensuring that the water flow flows in the device according to the predetermined direction, ensuring the normal operation of the measuring system and the accuracy of the measurement results.

[0034] In some embodiments, the sealing sleeve 9 is a sealing rubber sleeve. Rubber has high elasticity and flexibility, which can tightly fit the surface of the test block 8. Even if the surface of the test block 8 has a certain unevenness or irregular shape, the sealing rubber sleeve can fully contact it to form a reliable seal, preventing water from leaking out from the gap between the test block 8 and the sealing sleeve 9, ensuring that the measured seepage water is only the water seeping through the crack 81, and ensuring the accuracy of the measurement results. Moreover, the elasticity of the rubber sleeve can also provide a certain buffering protection effect for the test block 8, reducing the mechanical stress on the test block caused by device installation or other external factors, avoiding additional damage to the test block 8 during the measurement process, ensuring the integrity of the test block 8 and the stability of the crack 81 state, which is conducive to accurately measuring the amount of seepage water. It should be noted that the sealing sleeve can also be a sealing silica gel sleeve, soft plastic, etc., as long as it can ensure the sealing effect.

[0035] In some embodiments, the top of the second chamber 102 is vertically provided with a third vertical plate 15 and a fourth vertical plate 16 parallel to each other, which are arranged in a direction perpendicular to the depth of the crack 81, and the clamping space of the third vertical plate 15 and the fourth vertical plate 16 can clamp the sealing sleeve 9, which can provide accurate positioning for the sealing sleeve 9, so that it remains in a fixed position in the device, ensuring that the sealing sleeve 9 accurately corresponds to the position that needs to be sealed, avoiding the sealing sleeve 9 from shifting or shaking during use, thereby ensuring the stability and reliability of the sealing effect.

[0036] In some embodiments, the top of the second chamber 102 is provided with a sealing cover 12, which is also made of rubber material. After the sealing cover 12 is closed, it can fit the top of the sealing sleeve 9. When the sealing cover 12 is opened, the sealing sleeve 9 can be taken out through the cover opening. The size of the cover opening is not less than the size of the sealing sleeve, which ensures that the sealing sleeve can be put into and taken out of the second chamber through the cover opening. The sealing space formed by the sealing cover 12 and the sealing sleeve 9 helps to maintain the stability of the temperature and humidity in the chamber, which can reduce the influence of the external environment temperature and humidity, and ensure that the conditions in the chamber meet the requirements.

[0037] In some embodiments, the side wall of the water storage tank 11 is provided with a scale line, which is used to indicate the volume of collected water. Through the scale line, the volume of collected water can be read to obtain the water seepage amount. The operator does not need to use additional complex measuring tools or equipment. By directly observing the scale line on the side wall of the water storage tank 11, the current water seepage amount data can be quickly obtained, saving measurement time and improving work efficiency. It is especially suitable for scenarios that require frequent monitoring of water seepage amount.

[0038] In some embodiments, the water delivery device includes a water storage cylinder 3 and a pressurizing device 1. The water storage cylinder 3 is connected to the first chamber 101 through a water delivery pipe 7. A sealing ring 5 is arranged at the connection between the water delivery pipe 7 and the water storage cylinder 3 to prevent water leakage. The pressurizing device 1 is connected to the water storage cylinder 3 through an explosion-proof pressurizing pipe 2 to pressurize the water in the water storage cylinder 3. The pressurizing device 1 can pressurize the water in the water storage cylinder 3 through the explosion-proof pressurizing pipe 2, which can flexibly simulate different water pressures that the hydraulic concrete may be subjected to in actual use. For example, in hydraulic structures such as dams, concrete will be subjected to pressure generated by water bodies of different depths. By adjusting the pressurizing device 1 to the required water body pressure, the measurement environment can be more consistent with the actual situation, and the measurement result can have more reference value. The explosion-proof pressurizing pipe 2 is used to connect the pressurizing device 1 and the water storage cylinder 3. In the pressurizing process, even if the pressure abnormally rises, the explosion-proof pressurizing pipe 2 can effectively prevent dangerous situations such as explosion caused by excessive pressure, thereby protecting the personal safety of the operator and the safety of the surrounding environment.

[0039] As a preferred embodiment, the water storage cylinder 3 is fixedly arranged on the mounting seat 6, and the mounting seat 6 is provided with three rollers at the bottom, and the three rollers are arranged in an isosceles triangle shape, so as to facilitate the movement of the water storage cylinder 3 to a suitable position.

[0040] In some embodiments, a water inlet is arranged above the water storage cylinder 3, and a transparent window is arranged on the side wall. A filter screen is arranged in the water inlet, and the water inlet is used to connect the water inlet pipe 4 to supply water. The transparent window is used to display the water amount in the water storage cylinder 3. The filter screen arranged in the water inlet can effectively filter out impurities such as mud, leaves and stones in the water. This can prevent impurities from entering the water storage cylinder 3, avoid blocking or damage to the inside of the water storage cylinder 3, and also ensure that the water entering the first chamber 101 is relatively pure, prevent impurities from affecting the measurement accuracy of the water seepage amount of the concrete crack 81, and ensure that the measurement result is not disturbed by impurities. Through the transparent window, the worker can directly and clearly observe the water amount in the water storage cylinder 3. Without the aid of other measuring tools or opening the water storage cylinder 3, the amount of water can be known in real time, so that the problems of insufficient or excessive water can be found in time, so that corresponding measures can be taken in time.

[0041] It should be noted that the water inlet is provided with a control valve, which can control the opening and closing of the water inlet. When the water needs to be pressurized, the water inlet needs to be closed to prevent affecting the pressurization effect.
