Embodiment 1

[0036] refer to Figure 1-7 , an immersed tube filling type coal mining subsidence treatment device, comprising immersed pipe pieces 2 laid at equal intervals, adjacent immersed pipe pieces 2 connected from the beginning to the end are connected by connecting sleeves 5, and also include: openings set on the connecting sleeves 5 The water inlet 53 is fixedly connected with a filter screen 51 on the water inlet 53; the suction pipe 4 fixedly connected on the immersed pipe part 2, the water suction pipe 4 is used to communicate with each other the immersed pipe parts 2 laid at equal intervals, and the water suction pipe 4 is fixedly connected with The third extension pipe 41; the exhaust pipe 3 fixedly connected to the immersed pipe part 2, the exhaust pipe 3 is used to communicate the immersed pipe parts 2 laid at equal intervals, and the exhaust pipe 3 is fixedly connected with the second extension pipe 31; The silting pipe 22 arranged in the immersion pipe part 2 is fixedly co...

Embodiment 2

[0048] refer to Figure 7 , which is basically the same as that of Embodiment 1, furthermore: the connecting sleeve 5 is fixedly connected with a base 52;

[0049] The base 52 can make the water inlet 53 of the connecting sleeve 5 face upwards, which is convenient for collecting infiltrated rainwater, and at the same time avoids shaking between the connected immersed pipe parts 2 .

Embodiment 3

[0051] refer to Figure 4 , is basically the same as that of Embodiment 1, furthermore: one end of the second extension pipe 31 is threadedly connected with an installation box 32, and the installation box 32 is fixedly connected with a blocking net 33;

[0052] The mounting box 32, which is threadedly connected to one end of the second extension pipe 31, communicates with the second extension pipe 31, and can discharge the air in the immersed pipe part 2 when rainwater enters the immersed pipe part 2, and the blocking net 33 can prevent sundries from blocking the first Two extension pipes 31.

Abstract

The invention discloses an immersed tube filling type coal mining subsidence land treatment device and method, and belongs to the technical field of coal mining subsidence land treatment devices. An immersed tube filling type coal mining subsidence land treatment device comprises immersed tube parts which are laid at equal intervals, and the immersed tube parts which are adjacent end to end are connected through connecting sleeves. By using the immersed pipe fitting for filling, a through water containing space can be formed underground, rainwater can be collected in rainy days, water can be pumped from a water pumping pipe with one end in the immersed pipe fitting through a water pump for irrigation in dry seasons, and agricultural production is facilitated; meanwhile, the exciting quick-setting expansion waste residue cementing material is adopted for filling, the filling material can be obtained locally, self-sufficiency is achieved, a large amount of soil does not need to be filled, local soil resources are saved, meanwhile, the filling material is environmentally friendly, secondary pollution to the subsidence land is avoided, then ploughing is treated and restored, and the ecological and environment-friendly requirements are met.

Description

technical field [0001] The invention relates to the technical field of coal mining subsidence control devices, in particular to an immersed tube filling type coal mining subsidence control device and method. Background technique [0002] With the continuous strengthening of coal resource mining in our country, there will inevitably be a large number of gobs, which is also a problem that people need to focus on in the process of coal resource mining at the present stage; Replacement can reduce the damage to the environment caused by mining. It can be seen that filling mining is a green mining technology. In order to make this mining technology widely used and popularized, corresponding analysis should be done; [0003] In the prior art, the patent application number is 202110365694.9, and the application date is 2021.04.06. The name is an invention patent for an immersed tube filling type coal mining subsidence control method, which discloses dividing the subsidence water acc...
