Embodiment 1

[0038] refer to Figure 1 to Figure 6 Shown, a kind of method for draining the waste slag field combined forever, is characterized in that, comprises the following steps:

[0039] S1 Build a drainage blind ditch 2 at the bottom of the ditch in the ditch at the front of the dreg pile;

[0040] S2 Stack slag in separate platforms from bottom to top, excavate the first temporary drainage ditch 31 at the edge of the slag stacking line of the first-level platform in front of the first-level platform for slag stacking, and connect the two sides to the downstream of the spoil yard;

[0041] S3 After the stacking of the first-level platform is completed, the second temporary drainage ditch 32 is excavated along the edge of the second-level platform elevation slag line, and the two sides are connected to both sides of the first temporary drainage ditch 31;

[0042] When the second-level platform is piled up in S4, the first temporary drainage ditch 31 will be filled with spoil inside ...

Embodiment 2

[0053] Yet another embodiment of the present invention is a drainage system for waste slag field combining permanent and imminent, which is characterized in that it includes: a temporary drainage ditch opened along the edge of the slag stacking line at the height of the slag stacking platform, and a permanent water cutoff opened after the final slag stacking Ditch 1, and the bottom of the ditch in the spoil yard is provided with drainage blind ditch 2;

[0054] The permanent intercepting ditch 1 is formed by lining the ultimate temporary drainage ditch or excavating along the edge of the slag stacking line at the elevation of the final slag stacking platform;

[0055] The cross-section of the permanent intercepting ditch 1 is rectangular, and the inside of the permanent intercepting ditch 1 where the ditch water joins is superhigh by 20 cm to prevent the seasonal water from flowing into the permanent intercepting ditch and rushing into the waste slag field at a faster speed, an...

Abstract

The invention discloses a permanent and temporary combined waste slag yard drainage method and system. The permanent and temporary combined drainage method is characterized by comprising a temporary drainage ditch formed in the edge of a slag stacking line of a slag stacking platform, a permanent intercepting ditch formed after final slag stacking, and a drainage blind ditch formed in the ditch bottom of the waste slag field; and the permanent intercepting ditch is formed by lining an ultimate temporary drainage ditch or excavating along the edge of the elevation slag stacking line of the final slag stacking platform. According to the permanent and temporary combined drainage method and system for the waste slag yard, temporary drainage in construction of the waste slag yard and permanent water interception measures during operation of the waste slag yard after slag piling are taken into consideration; and meanwhile, on the basis of a self slag stacking platform, a permanent intercepting ditch construction operation platform is provided, flexibility and convenience are achieved, occupied space is reduced, investment is saved, and the safety and convenience of permanent intercepting ditch construction after final slag stacking are improved.

Description

technical field [0001] The invention belongs to the technical field of drainage of waste dregs, and in particular relates to a method and system for drainage of waste dregs combining permanent and impermanent drainage. Background technique [0002] After the comprehensive utilization of earth and stone excavated in production and construction projects, special waste dumps need to be set up for stacking; drainage measures for waste dumps are very important. In traditional waste dumps, it is necessary to build a permanent intercepting ditch before dumping waste, to intercept the surrounding catchment water, and avoid entering the spoil yard. In actual implementation, however, the reduction in the amount of waste slag has caused the permanent intercepting ditch to be far away from the slag pile line, forming "gutters" and "hanging ditches"; the increase in the amount of waste slag requires and conditions to expand the waste slag yard, and the abandoned slag has been built and r...
