A biological check dam used for erosion gully control comprises check dams which are arranged at different sections. The biological check dam is characterized in that aspen inserting trunks are planted at the upper end of each check dam and the lower end of each check dam to be used as frameworks, the inserting trunks are woven together and fixed through twigs of chaste trees to form protective faces, detritus or earth stone is stuffed between the protective face at the upper end and the protective face at the lower end, and the stuffing height is 45-55cm; a fixed net which is formed by twigs of chaste trees in a staggered weaving mode is paved on a stuffing base material in the check dam, the two ends of the fixed net are fixed on the inserting trunks through iron wires, and therefore the stability of the check dam is enhanced. The biological check dam is reasonable in structure, strong in stability and water permeability, simple in construction technology, low in manufacturing cost and ...

The invention provides equipment for determining the spoil loss allowance of developed and constructed projects. The equipment comprises a flow collecting device, a coaming, a rain gauge, a rainfall supporting tube, a rainfall spray nozzle, a pressure regulation controller, a water duct and a water supply device, wherein the flow collecting device is connected with the water outlet of the coaming, and the pressure regulation controller is arranged on the water duct. The method for determining thee spoil loss allowance of developed and constructed projects comprises the following steps: the coaming is filled with spoil of developed and constructed region to form a runoff plot, and the rainfall spray nozzle stimulates rainfall to brush the spoil in the coaming; and the slope runoff is generated along with the prolonging of the rainfall time, and runoff flows in the flow collecting device through the water outlet of the coaming and is collected by the flow collecting device for analysis. The ...
