Problems solved by technology

[0004] At present, the devices for simulating the development of underground structures in karst areas are still based on simple generalized simulations. The development of underground fissure pipelines is also concentrated in the case of a single degree of fissure, and rarely involves the complexity

Embodiment Construction

[0023]The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] The structure of the device for simulating the development of underground fissure pipelines in karst areas provided by the present invention is as follows: figure 1 As shown, the first supporting pier column 16, the second supporting pier column 1, the karst landform model, the underground diversion assembly, the water receiving bucket 27 and the sampling bottle. There are two buckets.

[0025] Both the first supporting pier 16 and the second supporting pier 1 are made of bricks. The height of the first supporting pier is 173 cm, and the height of the second supporting pier is 100 cm.

[0026] like figure 2 As shown, the karst landform model includes soil-filling tank 2, which is formed by pouring reinforced concrete. In the present embodiment, the bottom of the soil-filling tank 2 is square, and the length of the soil-filling tank bottom is 300cm, the width...

Abstract

The invention discloses a device for simulating development of a fractured pipeline in a karst region. The device, which simulates the development of underground fractured pipelines in the karst region through PVC steel hoses of different pore sizes, simulates the influence of the fractured pipelines on the soil loss and material migration in the karst region under the influence of the different degrees of bending (bending coefficients) under different development levels (aperture size change), constructs monitoring micro-areas of the surface-underground binary space water and soil process inthe karst region, analyzes the influence of the development of the fractured pipelines on the loss and material migration in the karst region through indoor artificial rainfall experiment, and revealsthe spatial coupling relationship between hydrological process and material migration process in underground fractured pipelines.

Description

technical field [0001] The invention belongs to the technical fields of hydrology, ecology, soil leakage and soil and water conservation, and specifically relates to a device for simulating the development of cracked pipelines in karst areas. It provides a scientific basis for the consolidation of climate governance results and the sustainable use of land. Background technique [0002] The unique karstification in the karst area forms a surface-underground dual spatial structure. Under the synergy of natural and human factors, the karst surface presents a rocky desertification landscape with discontinuous soil cover, shallow soil layers, and even large-scale bedrock exposure. Under the ground, cracks, dissolution pipes, funnels, shafts, sinkholes, and caves are formed under the dissolution of carbonate rock (limestone). The special "dual" structure and porous medium characteristics of the karst area make the runoff flowing in the shallow pores (cracks), pipes, and funnels d...
