Abstract
The utility model provides an annular-cavity double-wall well wall pipe, which is used for forming the well wall. The utility model is characterized in that the utility model is a cavity pipe made of modifying polyethylene material, the cross section of the pipe wall is in the double-wall annular-cavity shape, the lower end of the pipe wall is provided with a tip, according to the requirement of the well depth of the water well, a plurality of annular-cavity short pipes are stacked and inserted together, and the well wall of the water feeding well is formed. The utility model has the advantages of easy fabrication, corrosion resistance, high bending strength, capability of overcoming the defects of the existing well building material, easy transportation, easy installation, low cost and long service life of the water well built with the utility model.
Description
The utility model relates to a kind of ring-like cavity wall casing that is used to form the well wall.
Along with developing rapidly of industrial and agricultural production, the development and use of groundwater resources are extremely paid attention to.Water supply well quantity that grows with each passing day and shaft building material thereof, shaft building cost have become the important subject of relevant department.The particularly construction of dynamo-electric machine of water supply well at present often adopts traditional metal well casing, Asbestoscement pipe for well casing, bamboo well casing or concrete well to form the borehole wall.Although it has advantage separately, not corrosion-resistant because of it, application life is low, and the borehole wall volume of making is big, and transportation, installation are all inconvenient, and shaft building cost height, so influence the shaft building composite target.Therefore, select desirable shaft building material for use, improve the shaft building composite target, it is imperative to reduce the shaft building cost.
It is simple that the purpose of this utility model provides a kind of manufacturing process, and corrosion-resistant, resistance to compression, flexural strength are big, and convenient transportation in light weight is installed and is easy to novel wall casing---ring-like cavity double wall wall casing.
The purpose of this utility model is achieved in that this wall casing is to adopt modified polyethylene material to make, in the pipe is cavity, wall cross-section is that double wall is hollow ring-like, and the lower end band tip lumps together the folded insert group of a plurality of ring-like cavity borehole wall short tubes and promptly can be assembled into the water supply well borehole wall.
Because the utility model is the cavity pipe that adopts modified polyethylene material to make, so can obviously alleviate its weight, transportation, easy for installation.Wall cross-section is that double wall is hollow ring-like, and tension rib is symmetrical arranged between the double wall, and folded insert group dress back forms the borehole wall.Because of being plugged on together mutually behind each tube wall gluing, so in conjunction with firm, except that can significantly improving resistance to compression, flexural strength, the hollow-core construction of the borehole wall also can be saved a large amount of modified polyethylene materials.Wall casing of the present utility model is compared with the wall casing of prior art, has not only overcome some shortcomings of its existence effectively, and modified poly ethylene is corrosion-resistant, ageing resistance is strong but also have, all advantages that mechanical strength is high.Therefore, the water supply well that adopts the ring-like cavity wall casing of the utility model to build up can obviously improve the application life of well and reduce the shaft building cost, saves great deal of steel and obtains remarkable social benefit, helps wide popularization and application.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the longitudinal plan of a kind of concrete structure of the utility model.
1. be that 3. 2. outer wall be tension rib for inwall
Fig. 2 is the drawing in side sectional elevation of a kind of concrete structure of the utility model.
1. be that 3. 2. outer wall be tension rib for inwall
Fig. 3 is the borehole wall longitudinal plan that adopts the utility model to form.
Describe concrete structure of the present utility model in detail according to Fig. 1-3.This device adopts the modified polyethylene material extrusion modling to make the cavity pipe, and wall cross-section is that hollow double wall is ring-like.When building water supply well, the folded insert group of a plurality of ring-like cavity short tubes is fitted together, makes folded another stud tube wall upper end that is inserted in behind the gluing of stud tube wall lower end, foldedly insert a plurality of short tubes and form the well boreholes wall with this.For the bigger wall casing of hole diameter, the pipe outer wall along hole diameter to reinforcing rib evenly is set, also can be in pipe between the double wall along hole diameter to stiffener evenly is set, when going into the well between the tube and tube except that fold insert firmly admittedly, stiffener also should be welded to each other by the force request lap length.Process through hole at the pipe sidewall in addition, be used for doing filter pipe.
Claims (5)
1, a kind of ring-like cavity wall casing that has the tip of a branch is characterized in that the cavity pipe made by modified polyethylene material, and wall cross-section is that hollow double wall is ring-like, and folded up and down inserting connects.
2, wall casing according to claim 1 is characterized in that dowel is symmetrical arranged between the double wall.
3,, it is characterized in that managing outer wall and radially reinforcing rib can be set evenly along well casing according to claim 1 or the described wall casing of claim 2.
4,, it is characterized in that the connection between the tube and tube can be adopted other forms such as screw thread, wedge groove according to claim 1 or the described wall casing of claim 2.
5,, radially can establish stiffener along well casing between the double wall in it is characterized in that managing according to claim 1 or the described wall casing of claim 2.
