Problems solved by technology

[0003] On the other hand, for sludge dehydration, the primary disposal problem of sludge with extremely high moisture content is how to reduce its moisture content to below 60%. Using circulating salt solution dialysis to dehydrate sludge is a fast and efficient method , but the cost of the dialysate in this method is relatively high, and there is no vertical drainage device that can circulate and reuse the dialyzed liquid at this stage, and can eventually be emptied and recovered.

Embodiment 1

[0044] This embodiment provides a cylindrical strong drainage pipe with circulation emptying function, such as figure 1 , 2 As shown, it includes a pipeline 1 and a grid 2 arranged on the outer surface of the pipeline 1 along the axial direction of the pipeline 1 , and the outer surface of the grid 2 is covered with a filter membrane 4 .

[0045] In the above scheme, the outer surface of the grid 2 wraps the filter membrane 4 to form the drainage groove 3, and the distance between the grid 2 and the size of the grid 2 can be changed according to engineering needs to adapt to different geological conditions. At the same time, the pipeline 1 in the strong drainage pipe can also be used as the drainage pipeline 1, and the drainage groove 3 and the drainage pipeline 1 can be connected through the connection device to achieve the circulation function; the liquid stored in the strong drainage pipe can be quickly emptied by means of gas injection and the circular pipe is adopted It ...

Embodiment 2

[0048] This embodiment provides a device for drainage consolidation of soft foundations, such as image 3 As shown, it includes the strong drainage pipe 101 described in Embodiment 1, the upper end joint 102, the lower end joint 103, the partition 104 and the fixing ring 105;

[0049] Wherein the lower end joint 103 is made of a section of strong drain pipe, and the lower end joint 103 is inserted into the upper end of the lower end joint 103 and the lower end of the strong drain pipe 101 through a cylindrical connector 106 with an outer diameter equal to the inner diameter of the strong drain pipe 101 pipe 101 to realize two The connection between the two, the grille 2 of the strong drain pipe 101 is aligned with the grille 2 of the lower end joint 103, and the lower end of the lower end joint 103 grille 2 and the lower end of the pipeline 1 are sealed; the lower end joint 103 of the pipeline 1 A through hole 107 is opened on the inner wall, and the grid 2 of the lower end jo...

Embodiment 3

[0062] This embodiment provides a sludge dewatering device, such as Figure 8~10 As shown, it includes a strong drainage pipe 101, an upper joint 201 and a lower joint 301; the lower joint 301 is made of a section of strong drainage pipe, and the filter membrane 4 of the lower joint 301 and the strong drainage pipe 101 is covered with a dialysis membrane 5; the lower joint 301 passes through A cylindrical connector 401 with an outer diameter equal to the inner diameter of the strong drain pipe 101 pipe 1 is inserted into the upper end of the lower joint 301 and the lower end of the strong drain pipe 101 to realize the connection between the two. The grid 2 of the strong drain pipe 101 is connected to the The grids 2 of the lower joint 301 are aligned one by one, and the lower end of the grid 2 of the lower joint 301 and the lower end of the pipeline 1 are sealed; It communicates with the pipeline 1 through the through hole 107; the upper joint 201 includes an inner tube 202 an...

Abstract

The invention relates to a cylindrical forced water drainage pipe with a circulated evacuation function, a device and method used for soft foundation drainage consolidation and a device and method used for sludge water removal. The cylindrical forced water drainage pipe comprises a pipe body and gratings arranged on the outer surface of the pipe in the axial direction of the pipe, and the outer surfaces of the gratings are covered with filtering films.

Description

technical field [0001] The invention relates to the fields of foundation treatment and sludge dewatering, and more specifically, to a cylindrical strong drainage pipe with circulation and emptying functions, a device and a method. Background technique [0002] At present, one of the most commonly used methods in the field of soft soil foundation treatment is the drainage consolidation method. This method generates a water head difference in the foundation through loading pressure, so that the water in the soil is discharged along the vertical drainage body and gradually consolidates. Knot. Vertical drainage bodies usually use ordinary drainage boards and bagged sand wells. Both of these two vertical drainage bodies have only one-way water guide function. The water storage capacity in the vertical drainage body is small, and there is no ability to circulate water or liquid in it. The function of flow, let alone the function of emptying the water or liquid in it (that is, the...
