Description

Technical Field

[0002] Highway maintenance refers to a series of technical and management activities such as regular or irregular inspection, maintenance, repair and reinforcement of highways and their ancillary facilities, aiming to maintain the good technical status and beautiful environment of highways, and ensure the safety, smoothness, comfort and durability of highways. These activities include the maintenance and repair of highway structures such as pavements, bridges, tunnels, culverts, drainage systems, and protective facilities, as well as the maintenance of greening, environmental protection, and traffic safety facilities along the highways; ground permeability refers to the ability of surface or underground soil to allow water to pass through, which reflects the size of soil porosity and its connectivity. The level of ground permeability directly affects the conversion efficiency of surface water to groundwater, the water retention capacity of soil, and the hydrological characteristics such as the runoff rate of floods. When the ground permeability is good, rainwater can quickly penetrate into the soil layer, replenish groundwater resources, reduce surface runoff and soil erosion, and is conducive to maintaining ecological balance and sustainable use of water resources; on the contrary, if the ground permeability is poor, water will form runoff on the ground, which is easy to cause floods, urban waterlogging and other problems, and will also reduce groundwater recharge and affect the circulation of water resources.

[0026] See also Figure 1 and Figure 5 Initially, before activation, it is necessary to arrange multiple groups of variable water head permeators 1, numerical plates 2, glass test tubes 3, capping mechanisms 4 and docking mechanisms 5 in advance, fill the soil layer to be tested in the variable water head permeator 1, connect the pneumatic push rod 403 and the air pump body 404 to electricity and connect to the control terminal, start the pneumatic push rod 403 to control the sealing cover plate 405, and quickly dock the sealing cover plate 405 on the variable water head permeator 1. Unlike the traditional variable water head permeator 1, which also needs to be fixed with bolts, it is more convenient, time-saving and labor-saving. Especially when performing the installation operation of multiple groups of sealing cover plates 405, the automatic effect of the capping mechanism 4 can save more time;

[0027] Among them, the capping mechanism 4 adopts an air brake mode, which can automatically control the sealing cover plate 405 and automatically realize the capping operation, which effectively simplifies the user's operation process and improves the detection efficiency as a whole;

[0028] The docking mechanism 5 includes an outlet pipe head 503, an outlet pipe 504, a mounting sleeve 508 and a rubber air cushion 509. The upper end of the variable head permeator 1 is fixedly connected with the outlet pipe head 503, the outer side of the outlet pipe head 503 is provided with an outlet pipe 504, the outer side of the outlet pipe 504 is provided with a mounting sleeve 508, and the interior of the mounting sleeve 508 is provided with a rubber air cushion 509. The docking mechanism 5 also includes an inlet pipe head 501 and an inlet pipe 502. The rear end of the variable head permeator 1 is fixedly installed with the inlet pipe head 501, the outer side of the inlet pipe head 501 is provided with the inlet pipe 502, and the variable head permeator 1 is provided with the inlet pipe head 501.

[0029] See also Figure 4 and Figure 5 Before activation, it is necessary to ensure that the gas pipeline 511 is connected to the air pump body 404.

When activated, the user only needs to put the pipe with a wider diameter on the corresponding pipe head. Different from the pipe in the traditional variable head permeator 1, which has a smaller diameter and requires the user to spend time on docking operations, the pipe diameter of the local surface permeability detection device is wider and can be quickly docked. Then, the air pump body 404 is started to inject air into the rubber air cushion 509, so that the rubber air cushion 509 is inflated and tightly squeezes the pipe, so that the rubber pipe fits tightly on the corresponding pipe head;

[0030] Among them, the docking mechanism 5 uses the air brake function of the capping mechanism 4, and the user quickly inserts the pipe with a wider diameter into the pipe head, and then starts the docking mechanism 5, and adopts the air pressure clamping method to automatically and quickly seal and connect each pipe with the variable head permeator 1. The user does not need to spend time and effort to plug the pipe and the pipe head for the pipe with a wider diameter, which effectively improves the efficiency of the preparation work in the detection operation;

[0031] The working principle of the utility model is: first, fill the soil layer to be detected in the variable water head permeator 1, then connect the pneumatic push rod 403 and the air pump body 404 to electricity and connect to the control terminal, start the pneumatic push rod 403 to control the sealing cover plate 405. Since the sealing mechanism 4 adopts an air brake method, the sealing cover plate 405 can be automatically docked on the variable water head permeator 1. This process does not require the use of bolts to limit and fix, which greatly simplifies the user's operation process; at the same time, the docking mechanism 5 includes a water outlet pipe head 503, a water outlet pipe 504, a mounting sleeve 508 and a rubber air cushion 509, as well as components such as a water inlet pipe head 501, a water inlet pipe 502 and an air outlet pipe head 505. Components such as mounting sleeves 508, rubber air cushions 509, limiting rings 512 and sealing grooves 513 are distributed on the water inlet pipe head 501, the water outlet pipe head 503 and the air outlet pipe head 505. When activated, the user only needs to put a pipe with a wider diameter on the corresponding pipe head. The road pipe has a wider diameter and can be quickly docked without the need for users to spend time on docking operations like the traditional variable head permeator 1. Subsequently, the air pump body 404 is started to inject air into the rubber air cushion 509. The rubber air cushion 509 is inflated and tightly squeezes the pipe, so that the rubber pipe fits tightly on the corresponding pipe head. With the help of the air braking function of the sealing mechanism 4, the user quickly inserts the pipe with a wider diameter into the pipe head and then starts the docking mechanism 5. By adopting the air pressure clamping method, each pipe can be automatically and quickly sealed and connected with the variable head permeator 1. During the entire detection process, the use of the automated sealing mechanism 4 and the quickly docked pipe effectively improves the efficiency of the detection operation, reduces the difficulty of user operation, and makes the detection work more convenient, time-saving and labor-saving. This ground permeability detection device has broad application prospects in the field of highway maintenance, and can provide accurate and efficient permeability data support for highway maintenance.
