Method and equipment for determining spoil loss allowance of developed and constructed projects

Abstract

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 method and equipment have the advantages of realizing monitoring on soil loss amount in certain water collection regions, being incapable of being influenced by the outside factor, carrying out full-process monitoring on soil loss before the project construction, in construction preparation period, during construction disturbance period and the like, and being accurate and trustable for monitored results.

Description

technical field [0001] The invention relates to the technical field of water and soil loss monitoring, in particular to a method and equipment for measuring the amount of soil loss in development and construction projects. Background technique [0002] In recent years, due to large-scale mining and road engineering and other development and construction projects, a large number of exposed spoils have been formed, which are prone to a series of negative impacts such as soil erosion, environmental pollution, ecological imbalance, landscape destruction, and microclimate changes. However, there is currently no special equipment for monitoring the amount of spoil loss in development and construction projects. Existing predictions of spoil loss in development and construction projects are based on empirical formulas for estimation. Generally, the amount of spoil loss is monitored by setting monitoring points. Using the steel brazing method to monitor under natural rainfall conditi...

However, there is currently no special equipment for monitoring the amount of spoil loss in development and construction projects. Existing predictions of spoil loss in development and construction projects are based on empirical formulas for estimation. Generally, the amount of spoil loss is monitored by setting monitoring points. Using the steel brazing method to monitor under natural rainfall conditions, the monitoring method is rough, the data accuracy is low, and it is easily affected by human and other factors to increase the error, reduce the accuracy of the monitoring data, and cannot scientifically monitor the development and construction projects. The amount of water and soil loss of soil has no practical guiding significance for the prevention and control of spoil loss in development and construction projects

[0003] At present, without the assistance of monitoring equipment, the monitoring of the amount of spoil loss in development and construction projects has brought a lot of inconvenience to the monitoring personnel, and the operability is poor

It is not easy to monitor especially under nighttime rainfall conditions; there are certain dangers in implementing monitoring under heavy rain conditions; in the case of dry years, monitoring work cannot be carried out smoothly as scheduled, which will lead to the lack of monitoring data; construction in mountainous areas Project monitoring also increases the difficulty and danger of implementing monitoring work
