TECHNICAL FIELD
[0001] The present application relates to the technical field of foundation pit engineering monitoring, in particular to a inclinometer pipe connecting pipe for foundation pit water level monitoring. BACKGROUND
[0002] Foundation pit monitoring is an important link in foundation pit engineering construction, which refers to various observation and analysis work on the changes of foundation pit rock-soil properties, supporting structure displacement and surrounding environment conditions during foundation pit excavation and underground engineering construction, and timely feedback of monitoring results to predict the development of deformation and stability state caused by further construction, to determine the degree of influence of construction on surrounding environment to guide design and construction and realize so-called information-based construction.
[0003] At present, an inclinometer pipe is often used to detect the underground water level in the foundation pit, which opens a detection hole in the side wall of the inclinometer pipe, then embeds the inclinometer pipe in the soil around the foundation pit, lets the underground water enter the inclinometer pipe through the detection hole, and then measures the water level in the inclinometer pipe. However, the detection hole on the inclinometer pipe embedded in the foundation pit is often blocked, resulting in that the water level monitoring cannot continue. SUMMARY
[0004] The present application aims to solve the problem of frequent blockage of the detection hole on the inclinometer pipe in the prior art, and provides an inclinometer pipe connecting pipe for foundation pit water level monitoring, which uses the anti-blocking device on the water permeable passage to not only allow water to pass through, but also greatly reduce the risk of blockage.
[0005] Technical scheme: The inclinometer pipe connecting pipe for foundation pit water level monitoring comprises an inclinometer pipe body and a water inlet connecting pipe, the water inlet connecting pipe is sleeved on the outer wall of the inclinometer pipe body, the water inlet connecting pipe comprises two connecting sections, a middle section water inlet pipe is arranged between the two connecting sections, the part of the inclinometer pipe body in contact with the middle section water inlet pipe is hollow, facilitating water inlet and residue filtration of the middle section water inlet pipe; when the underground water enters the inclinometer pipe body through the middle section water inlet pipe, the middle section water inlet pipe filters the underground water. Filtering the underground water through the middle section water inlet pipe can effectively prevent silt from blocking.
[0006] Further, the middle section water inlet pipe is provided with an anti-blocking device, the anti-blocking device comprises a group of concave clamping grooves uniformly distributed in the circumferential direction of the middle section water inlet pipe, and a group of first narrow water inlet passages are arranged in the vertical direction of the concave clamping grooves. Through the design of the concave clamping grooves and the narrow water inlet passages uniformly distributed in the circumferential direction of the middle section water inlet pipe, the larger particles in the water can be effectively intercepted, preventing these impurities from entering the inclinometer pipe body, thereby reducing the risk of blockage inside the pipe.
[0007] Further, the anti-blocking device further comprises a groove block corresponding in size to the recessed clamping groove, and a plurality of second narrow water inlet channels are arranged in the vertical direction of the groove block, and when the groove block is placed in the recessed clamping groove, the first narrow water inlet channels and the second narrow water inlet channels are staggered, which can reduce the risk of blocking caused by direct water flow impact on the same channel, thereby improving the anti-blocking capability of the pipeline.
[0008] Further, the material of the water inlet connecting pipe and the groove block is stainless steel, which ensures the reliability and durability of the entire device.
[0009] Further, a first layer of filter screen and a second layer of filter screen are arranged on the groove block, the first layer of filter screen is arranged on the side of the second narrow water inlet channel close to the groove block, the second layer of filter screen is arranged on the side of the first layer of filter screen close to the recessed clamping groove, and a gap (space after compression of the elastic compression strip) is left between the first layer of filter screen and the second layer of filter screen. The impurities in the water can be filtered twice, improving the filtering effect, and the gap can prevent the filter screen from being blocked by large particles, ensuring the smooth flow of water.
[0010] Further, a ring-shaped elastic compression strip and a fixing screw hole for easy fixing are arranged on the periphery of the groove block. The ring-shaped elastic compression strip facilitates the sealing of the groove block and the recessed clamping groove, preventing particles in the water from directly entering the inclinometer tube without passing through the first layer of filter screen and the second layer of filter screen, and the fixing screw hole facilitates the fixed connection of the groove block and the recessed clamping groove.
[0011] Further, a connecting segment screw hole and a connecting segment guide groove are arranged on the connecting segment, which facilitates the connection of the inclinometer tube adjacent to the upper and lower parts.
[0012] Further, an intermediate water inlet section guide groove corresponding to the connecting segment guide groove is arranged on the inner wall of the intermediate water inlet section, which can provide a sliding path for the inclinometer probe, and the intermediate water inlet section guide groove facilitates smooth connection with the inclinometer tube main body inserted into the water inlet connecting pipe, ensuring smooth passage of the inclinometer probe.
[0013] Advantages: Compared with the prior art, the advantages of the present application are:
[0014] (1) The present application is provided with an anti-blocking device, including a recessed clamping groove and a groove block, and narrow water inlet channels are arranged on the recessed clamping groove and the groove block. By arranging narrow water inlet channels, impurities and particles in the water can be effectively intercepted, reducing the risk of pipeline blockage and improving overall filtration efficiency; two layers of filter screens are arranged on the groove block to filter residues, and the double-layer filter screen significantly improves the filtration effect through a unique structural design, effectively blocking small particles.
[0015] (2) The recessed clamping grooves are evenly distributed on the circumference of the intermediate water inlet pipe, which can ensure that the water flow is evenly filtered when passing through, avoiding uneven filtration or blockage problems caused by excessive or insufficient water flow speed in local areas.
[0016] (3) The design of the concave slot and narrow water inlet channel in this invention optimizes the structure of the anti-clogging device, making it more compact, while improving the filtration effect and water flow efficiency of the device. Attached Figure Description
