Problems solved by technology

At home and abroad, some pipes are usually buried in the soil to simply collect the groundwater and soil loss. The measurement accuracy is low, and the soil is also greatly disturbed, so it is impossible to monitor the soil and water loss in the actual sense.

Embodiment 1

[0014] Embodiment 1: as figure 1 Shown, comprise soil collector, tripod 11 and microwave drying device 12, and tripod 11 is movably installed on the bottom of soil collector, so that better fixed soil collector according to ground ruggedness in the cave; Microwave drying device 12 adopts microwave oven (The power is 800~1000w), which is mainly used to microwave the soil solution collected by the soil collector within a certain period of time until it is dry to obtain soil. The soil collector is divided into three parts from top to bottom, and each layer is connected to each other through inner buckles to form a whole. The first part includes 100-mesh nylon gauze cloth 1, the first layer of 250-mesh nylon mesh 2 and quartz sand 3, This part is mainly for preliminary filtration, that is, the nylon mesh gauze 1 mainly filters the soil with a diameter > 110 μm; the quartz sand 3 is mainly used for absorbing the soil with a diameter of 20μm; high-density sponge 5 adopts a density o...

Abstract

The invention discloses a soil collecting device for cave drip water and fissure water in a karst region. The soil collecting device comprises a soil collector, a support frame (11) and a microwave drying device (12), wherein the support frame (11) is movably mounted at the bottom of the soil collector; the soil collector is divided into three parts from top to bottom, wherein the first part comprises a nylon mesh gauze (1), a first layer of nylon mesh sieve (2) and quartz sand (3); the second part comprises a second layer of nylon mesh sieve (4) and high-density sponge (5); the third part comprises a water collecting basin (6) and a fine filter screen (7); a water drainage pipe (8) is connected to the bottom of the water collecting basin (6); a container (9) is placed under the water drainage pipe (8). The soil collecting device disclosed by the invention has the characteristics of being simple in structure, high in measurement precision, convenient to operate and maintain, solid and durable, energy-saving and efficient, low in cost, continuous in operation and the like and has an obvious advantage in the study on soil loss amount and precipitation response.

Description

technical field [0001] The invention relates to a soil collection device, in particular to a soil collection device for cave dripping water and crevice water in karst areas. Background technique [0002] At present, the devices used for water treatment at home and abroad mainly include integrated sewage devices with curved bottoms, screen-type circular sedimentation and sand discharge tanks, sedimentation tanks, sedimentation tanks, etc., but these devices are mainly for the filtration of muddy water and sewage. Treatment, and mainly for the loss of surface water and soil, not for the collection of underground soil, and the design is more complicated. However, soil collection devices for dripping water and crevice water in caves widely distributed in karst areas are very rare, and groundwater and soil loss in karst areas is a relatively serious part. At home and abroad, some pipes are usually buried in the soil to simply collect the groundwater and soil loss. The measuremen...
