The application provides a honeycomb trapezoidal riprap frame for a seawall structure and a construction method, and relates to the field of water conservancy projects. The honeycomb trapezoidal riprap frame is composed of a plurality of diamond modules, support columns and small ripraps to form a trapezoidal slope protection structure. The plurality of diamond modules are arranged in an alternating and staggered manner. The adjacent diamond modules are connected by the support columns. The diamond modules are filled with small ripraps. The diamond module includes a diamond block body. A semicircular groove in a semicircular shape is arranged on each of the four corners of the diamond block body. The semicircular grooves of the adjacent two diamond block bodies can completely wrap the support column. A clamping groove is vertically arranged at the middle position of the upper and lower surfaces of the four edges of the diamond block body. The honeycomb trapezoidal riprap frame limits the small ripraps to prevent the small ripraps from being washed away by the tidal current and causing piping and other risks. At the same time, the load stress of the small ripraps is dispersed in block form to each diamond module, which greatly improves the stability of the seawall and reduces the risk of dam collapse.

The application discloses a dam seepage drainage and reinforcement method for a tailing pond, which comprises a reinforcement part and a seepage drainage part; the reinforcement part and the seepage drainage part are arranged on two sides of an initial dam respectively; the reinforcement part is arranged on the inner side and the outer side of the initial dam to reinforce the initial dam, so as to improve the upper limit of the bearing water pressure and the upper limit of the accumulated dam pressure; the seepage drainage part is arranged on the outer side of the initial dam to reinforce the outer side of the initial dam and improve the seepage drainage effect of the initial dam. The initial dam is improved by the reinforcement part and the seepage drainage part. When the tailing pond is filled with water, the water pressure generated by the rising water level and the accumulated dam pressure generated by the tailing slag accumulation will generate pressure on the initial dam. The reinforcement part can effectively improve the upper limit of the bearing water pressure and the upper limit of the accumulated dam pressure. After the water storage, in addition to the seepage drainage of the initial dam, the seepage drainage part arranged on the outer side can also assist in the seepage drainage, so as to relieve the pressure of the initial dam, improve the seepage drainage efficiency and reduce the risk of dam collapse.

This invention belongs to the field of geological engineering and natural disaster simulation technology, and relates to an experimental device and method for simulating the disaster chain from a high-altitude, long-distance landslide in a cold region to a flood. The device includes a support mechanism, an acceleration mechanism, a loading vehicle, a motion mechanism, a freezing mechanism, a water tank, a water spraying mechanism, and a monitoring mechanism. The freezing and water spraying mechanisms simulate the low temperature and rainfall environment of a cold region; the acceleration mechanism drives the loading vehicle to simulate the initiation of a high-altitude landslide; the landslide mass scrapes and encases moist frozen soil samples in the motion mechanism, evolving into a debris flow under continuous water spraying; the debris flow rushes into the water tank and accumulates to form a simulated landslide dam, simulating the process of blocking a river; subsequently, under the action of upstream water, the dam collapses, triggering a simulated downstream flood. This invention can simulate and monitor the entire disaster chain of a high-altitude, long-distance landslide in a cold region – debris flow – river blockage – flood, providing an effective physical simulation technology for disaster risk assessment and prevention.

The utility model provides a slope anti-collapse slope structure, which is characterized in that a drainage channel is arranged at the slope toe of a seepage-stopping dam and horizontally extends along the extension direction of the seepage-stopping dam, and rock blocks are accumulated in the drainage channel and at the slope toe; the steps are arranged on the slope surface of the seepage interception dam and horizontally extend in the extending direction of the seepage interception dam; a plurality of soil engineering bags are laid along the slope surface and the steps of the seepage interception dam to form a soil engineering bag layer; drainage pipes are arranged in the seepage interception dam, one ends of the multiple drainage pipes are diverged in a fan shape, and the other ends of the multiple drainage pipes penetrate through the slope face of the seepage interception dam and stretch out of the geotechnical bag layer. The slope surface of the seepage interception dam is protected through the soil engineering bags, seepage water in the seepage interception dam is drained and guided in combination with the drainage pipe, the drainage efficiency of the seepage interception dam is remarkably improved, and therefore the seepage pressure in the seepage interception dam is reduced, and the possibility that the slope of the seepage interception dam collapses is reduced.
