Description

Technical Field

[0001] The utility model relates to a dike piping danger handling skill assessment device, belonging to the technical field of flood control and emergency rescue assessment equipment. Background Art

[0002] Piping refers to the phenomenon that soil particles are carried out by seepage and destroyed. The development of piping danger is the most rapid in soil flow. Its process is that as the water level rises, the sand and soil carried out by the gushing water increase, and the amount of gushing water also increases. As the amount of gushing water increases, more sand and soil are carried out. If the sand layer under the foundation of the nearby embankment (gate) is emptied, it will cause the embankment (gate) to drop suddenly, and even cause the disaster of dam breach.

[0003] The principle of emergency rescue of pipe bursts should be to prevent the gushing water from carrying sand, but to leave a way for water to seep out. This will not only prevent the sand layer from being damaged, but also reduce the nearby seepage pressure, so that the danger can be controlled and stabilized. The training subjects for emergency rescue of pipe bursts on embankments lack real scene reproduction, lack systematic training and assessment, and require a large number of labor forces to complete. It is not suitable for individual operations of flood control and rescue team members and on-site operations of senior commanders. The training intensity is high and it is easy to hurt people. Utility Model Content

[0004] In order to solve the technical problems that the skill assessment of dike piping hazard is difficult, non-intuitive, difficult for single soldiers to operate, and difficult for senior commanders to operate, the utility model provides a dike piping hazard handling skill assessment device.

[0005] The technical solution of the utility model is as follows:

[0006] A device for assessing skills in handling dangerous situations of pipe bursts in dikes, characterized in that it comprises:

[0007] The operating platform includes a support frame and an earthen embankment; the support frame includes a support platform and four support legs located below the support platform; the earthen embankment is laid on the support platform, including the embankment and the ground near the embankment foot; the embankment is provided with an embankment pile number sign;

[0008] A water circulation component includes a mud pool, a mud pump, a water inlet pipe, a pipe gushing port, a return water trough, and a return water pipe; the mud pool is arranged below the supporting platform, and a mixer is arranged in the mud pool; the mud pump is located in the mud pool, and the mud pump is connected to the pipe gushing port through the water inlet pipe; the pipe gushing port penetrates the ground near the foot of the embankment and is flush with the top of the ground; the return water trough is arranged on the supporting platform and arranged along the outer side of the earthen embankment, and the return water pipe is connected to the return water trough and the mud pool respectively;

[0009] Dangerous situation handling props (i.e., assessment props) include earthbag enclosures, gravel filter layers, and PVC pipes; the earthbag enclosures are stacked with mini earthbags staggered around the pipe burst outlet, the gravel filter layer is laid in the earthbag enclosures, and the PVC pipe runs through the side walls of the earthbag enclosures and is located above the gravel filter layer. The gravel filter layer includes a coarse sand layer, a small gravel layer, and a large gravel layer, and the top of the earthbag enclosure is higher than the top of the gravel filter layer.

[0010] The return water trough is a U-shaped structure, surrounding the edge of the earthen embankment. The return water trough is formed by a water retaining plate arranged along the edge of the earthen embankment, the water retaining plate is kept at a certain distance from the side of the earthen embankment, and the top of the water retaining plate is higher than the ground near the embankment foot.

[0011] When in use, add appropriate mud liquid into the mud pool under the operating table and stir it evenly with a mixer to make the mud and sand uniform. The mud liquid is transported to the pipe outlet through the water inlet pipe by a mud pump, forming a soil flow or pipe burst hazard. The emitting liquid overflows to the return water tank through the platform, and falls back to the mud pool through the return water pipe, forming a circulating pipe burst hazard.

[0012] When dealing with dangerous situations:

[0013] 1. Trainees observe the dangerous points of pipe bursts on the dike (i.e. pipe burst openings) and the pile number signs on the dike, record the dangerous conditions of pipe bursts, measure the diameter of pipe burst openings, and calculate the inner wall diameter of the earthbag enclosure, the bottom paving range, and the base clearing range;

[0014] 2. Use mini earthbags to stack the earthbags along the diameter range of the inner wall of the well, with the mouths of the earthbags stacked downward and staggered to form a pipe well;

[0015] 3. After the earthbags are stacked around the well, fill the well with coarse sand, small gravel and large gravel layers according to the direction of water seepage. After waiting for the clear water to emerge, arrange a PVC pipe as a drain on the top of the clear water to drain the seepage water.

[0016] 4. On-site examiners can accurately assign points and comments on individual assessments based on the students' handling effects and processes of pipe burst hazards. The key points of the assessment include: measurement of pipe burst outlets; determination of base clearing range and earthbag paving range; determination of well enclosure height, earthbag width and stability; selection of sand and gravel filter materials and layered laying; setting of drainage outlets and layout directions.

[0017] The utility model is a skill assessment device for handling embankment pipe burst hazards, which is a special equipment for flood control and rescue assessment. It solves the existing individual assessment method for flood control and rescue team members and commanders, and is suitable for indoor single-person practical assessment of embankment pipe burst hazards, pipe burst hazard simulation, and related rescue method tests.
