Abstract
The utility model relates to a large caliber water filtration tube, which comprises a cylindrical tube body which is made from steel bars and concrete, wherein, the large bore water filtering tube also comprises a bar hole-shaped water filtration hole and prepared holes. The bar hole-shaped water filtration hole is arranged in the middle section of a tube body. The prepared holes are arranged on both ends of the tube body. The utility model has the advantages of large caliber, high percent opening, etc.
Description
The utility model relates to a kind of heavy caliber filter pipe.
The difference owing to the hydrology and hydrogeological conditions and stratum conditions of water storage in China extracts the well casing shape of using when utilizing underground water to become well and also has nothing in common with each other at present, maximum 400 millimeters of its bore, and minimum 300 millimeters or littler, percent opening is also lower.They can only suit to use in rich water formation condition, and for semiarid zone and Plain poor-water district, because the bore of above-mentioned well casing is little, the water storage capacity is few, is difficult to accomplish with solving people and animals' drinking water problem.
The purpose of this utility model provides that a kind of bore is big, percent opening is high and is suitable for the semiarid zone and heavy caliber filter pipe that the Plain water-deficient area uses.
Task of the present utility model is achieved in that this heavy caliber filter pipe comprises the cylindrical tube of being made by reinforcing bar and concrete, wherein it also comprises the treatment hole and the preformed hole of bar hole shape, the treatment hole of bar hole shape is located at the stage casing of body, and preformed hole is located at the two ends of body; The length of filter pipe is 1～4 meter, and internal diameter is 0.6～1.2 meter, and percent opening reaches 10%～13%.
Because the utility model adopted technique scheme, therefore compare with background technology, have that bore is big, percent opening is high and be suitable for the semiarid zone and advantage such as Plain water-deficient area use.The utility model is applicable to that also doing horizontal well in the hydraulic engineering of damming uses.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional drawing among Fig. 1;
Fig. 3 is the B-B sectional drawing among Fig. 1.
As Fig. 1, Fig. 2 and shown in Figure 3, this filter pipe comprises the cylindrical tube of being made by reinforcing bar 4 and concrete 1, wherein it also comprises the treatment hole 2 and the preformed hole 3 of bar hole shape, the treatment hole 2 of bar hole shape is located at the stage casing of body 1, and making percent opening reach 10%, preformed hole 3 is located at the two ends of body 1.The length of this filter pipe is 2 meters, and internal diameter is 0.8 meter, and wall thickness is 0.05 meter.
The internal diameter of above-mentioned filter pipe can also be selected between 0.6～1.2 meter, and percent opening is selected between 10%～13%, and length is selected between 1～4 meter.
