Detailed description of the invention
As shown in Figure 1, Figure 2, shown in Fig. 3 and 4 be a kind of guard system for mud-rock flow that can effectively alleviate and reduce the life and property loss degree that mud-rock flow causes provided by the invention.Described guard system comprises stake and to block structure 1, and described stake blocks structure 1 perpendicular on the raceway groove basis 2 being arranged in outside the instable slope that needs to carry out protecting in mud-rock flow movement direction.A set ofly include stake above by arranging and to block the guard system of structure 1, and structure 1 of this being blocked is perpendicular on the raceway groove basis 2 being arranged in outside the instable slope that needs to carry out protecting in mud-rock flow movement direction.Like this, when mud-rock flow occurs, dump and under containing large gauge block stone, the mixture of silt particle and current, run into described stake block structure 1 time, because described stake blocks structure 1 in lattice-shaped, thus make described stake structure 1 of blocking can block the larger block stone of diameter, and tiny silt and current can directly to be blocked structure 1 through described stake, avoid occurring that a large amount of block stone impacts, the downstream raceway groove of collision and covering mud-rock flow process, both can effectively protect downstream channel memory cell house owed by a citizen, forests etc. are relatively high, comparatively stable building and/or forest cover etc., reach the object effectively alleviating and reduce the life and property loss degree that mud-rock flow causes.
In above-mentioned embodiment, to block the structure of structure 1 to simplify described stake, both the object of protecting had been realized, facilitate built on-site again, to reduce cost of production, submit efficiency of construction to, it is 4 that described stake blocks that structure 1 comprises grid stake 3 and strengthen connection, described grid stake 3 along the vertical direction of mud-rock flow movement spaced be arranged on described raceway groove basis 2, it is that 4 connections are as a whole that the upper end of described grid stake 3 is connected by described reinforcement.And in order to ensure maximized energy dissipating, mitigation, the top being 4 in described reinforcement connection is also provided with energy dissipating dredging flow groove 5.Like this, after both having made reinforcement connect to be the lattice structure of less than 4 to block because of boulder, the described energy dissipating dredging flow groove 5 on top still can the energy of the effective mud-rock flow of the quick undershoot of cancellation, to reduce the destructiveness of the boulder of high-speed motion.
Further, in order to improve the impact resistance of described grid stake 3, meanwhile, the large solids stopped in mud-rock flow can tried one's best again, is set greater than 2.5 by the width of the cross section of described grid stake 3 and the ratio of thickness; And the cross section of described grid stake 3 is set to the thick wide stern construction in thin rear end, front end, now described width is the described width of grid stake 3 cross section and the ratio of cross section maximum gauge with the ratio of thickness; Meanwhile, in described wide stern construction, the width of described grid stake 3 cross section is divided into light filling bar part grid stake 8 and thick section of part grid stake 9, the width of described light filling bar part grid stake 8 is arranged be less than the width of described thick section of part grid stake 9; Preferred embodiment is now, the thickness of described light filling bar part grid stake 8 is 1/2 to two/5th of the thickness of described thick section of part grid stake 9; And the structure that described light filling bar part grid stake 8 adopts gradual change shape to thicken with described thick section of part grid stake 9 from transition position 10 backward.
Meanwhile, in order to avoid described guard system is damaged by entirety together with basis when mud-rock flow occurs, in described raceway groove basis 2, be provided with the foundation pile 6 stretched in these raceway groove basis 2 grounds; And preferred described raceway groove basis 2 is concrete bearing platform plate.Meanwhile, concrete apron 7 is also connected with in the outside of described concrete bearing platform plate.Like this, just can improve the bonding strength on guard system described in the application and raceway groove basis 2, avoid guard system to be damaged by entirety together with basis when mud-rock flow occurs to greatest extent.
