Abstract
A slip casting over length anchor bar comprising an anchor bar (3), whose upper end is fixed and connected with an exhaust pipe (2). The anchor bar (3) and exhaust pipe (2) are connected with a grouting pipe (1) by wooden seal plug (4). The utility model has convenient construction, safety and reliability, long acting time, decreased loss rate, improved working efficiency and is especially suitable for supporting use in down-well operation when the stope roof is exposed with large area and long time in the mine with high mechanization degree.
Description
Affiliated technical field:
The utility model relates to a kind of mine support equipment, and particularly a kind of long-time top board of higher down-hole, the mine large tracts of land of mechanization degree that is used for exposes the anchor pole that stope carries out supporting
Background technology:
The mine that present domestic orebody thickness is higher, trend is long generally adopts the large-scale mobile equipment in down-hole to construct, this just requires stope and down-hole part exposed area and highly increases, adopt traditional support pattern that its top board safeguarded that reinforcement effect is not obvious, the tradition rock-bolt length generally is not more than three meters, and rock joint or tomography bigger in the stope are difficult to use traditional anchor pole to reinforce.Caused the working environment poor stability, the some column bleed is excessive in the stope, and the utilization rate reduction of main equipment etc. has a strong impact on the situation of the rate of recovery and operating efficiency.
The invention task:
The purpose of this utility model will provide a kind of exactly and be applicable to that stope top board exposed area is big, the time is long, and top board has than the mine of major fault and uses, the slip casting extra long anchor bar of have easy construction, safe and reliable, long action time, reduction loss late, increasing work efficiency.
The purpose of this utility model is achieved in that a kind of slip casting extra long anchor bar, form by anchor pole (3), the fixedly connected stack in upper end (2) that it is characterized in that described anchor pole (3), anchor pole (3), stack (2) connect Grouting Pipe (1) by wooden shutoff plug (4).
An optimum implementation of the present utility model: stack (2) adopts the PE plastics to make, and Grouting Pipe (1) adopts the PVC plastics to make, and anchor pole (3) adopts screw-thread steel.
The utility model compared with prior art has the following advantages:
1, because the form of structure that has adopted anchor pole (3), stack (2) to connect by wooden shutoff plug (4), thereby, it is long that the length of anchor pole (3) can reach 12m, can effectively suspend in midair big joint, tomography, once construction can be played good supporting effect to 4～5 layering stope top boards, easy construction, safe and reliable, long action time, reduction loss late.
2, construction speed is fast, can reach 50～60m/ days in the practice of construction, can satisfy the needs of rapid construction, increases work efficiency.
Accompanying drawing and drawing explanation:
Figure: be the utility model concrete structure schematic diagram.
1, Grouting Pipe 2, stack 3, anchor pole 4, wooden shutoff plug
The specific embodiment:
It is the 9mm screw-thread steel that anchor pole (3) adopts diameter, long 12m, fixedly connected in the top stack (2), stack (2) employing has certain compressive strength PE plastics makes, and internal diameter is 10mm, is connected wooden shutoff plug (4) on the outer wall of stack (2) and anchor pole (3), wooden shutoff plug (4) connects the outer wall of Grouting Pipe (1), Grouting Pipe (1) adopts internal diameter 20mm, wall thickness 4mm, and length is that the PVC plastics of 15m are made.
During use, anchor pole (3), stack (2), Grouting Pipe (1) are passed wooden shutoff plug (4), and the good boring of prior brill is put in the upper end of anchor pole (3), seals the lower end of boring with wooden shutoff plug (4), by Grouting Pipe (1) slip casting in the hole, get final product until filling with.
Claims (3)
1, a kind of slip casting extra long anchor bar is made up of anchor pole (3), it is characterized in that the fixedly connected stack in upper end (2) of described anchor pole (3), and anchor pole (3), stack (2) connect Grouting Pipe (1) by wooden shutoff plug (4).
2, slip casting extra long anchor bar according to claim 1 is characterized in that described stack (2) adopts the PE plastics to make, and Grouting Pipe (1) adopts the PVC plastics to make.
3, slip casting extra long anchor bar according to claim 1 and 2 is characterized in that described anchor pole (3) adopts screw-thread steel.
