Abstract
The utility model provides a cusp high pressure slip casting stock, includes anchor head (1), adapter sleeve (2), the hollow body of rod of cusp (3) and oval out grouting holes, anchor head (1) of hollow point form links to each other with adapter sleeve (2), has seted up oval out grouting holes A (4.1) on anchor head (1), adapter sleeve (2) link to each other with the hollow body of rod of cusp (3), have offered oval out grouting holes B (4.2) on adapter sleeve (2), and oval out grouting holes C (4.3) have been offered on two sides of the hollow body of rod of cusp (3). The utility model has the advantages of simple structure, convenient operation, saving cost, improvement anchor power. Through the inside high -pressure slip casting of the hollow body of rod of cusp (3), make the thick liquid follow the stratum that oval out grouting holes entered into anchor head (1), adapter sleeve (2) and the hollow body of rod of cusp (3) surface, the whole member of stock is big with the area of contact of thick liquid, and treats that the thick liquid of cusp surface solidifies the back, plays the effect of blocking the stock.
Description
Technical field
The utility model belongs to a kind of dentation high pressure slurry filling anchor bolt in civil engineering bolt support field.Relate to Anchor in Geotechnical Engineering support technology field.
Background technology
The bolt support technology of traditional first drilling holes and late grouting is widely used in base pit engineering, slope project, but also there are some shortcomings, as 1. conventional anchor external surface and surrounding contact area is little, frictional force is low, makes the tensile strength of its anchor pole low; 2. the entire length of anchor pole is longer, and cost is high.In conjunction with to the outer surface structure improvement opportunity of the conventional anchor body of rod and bolt grouting location improvement technology, propose a kind of dentation high pressure slurry filling anchor bolt support technology, entirety improves anchored force, the tensile strength of anchor pole.
The utility model is achieved by the following technical solution: a kind of dentation high pressure slurry filling anchor bolt is made up of anchor head (1), splicing sleeve (2), dentation hollow rod body (3) and oval slurry outlet; Splicing sleeve (2) connects anchor head (1) and dentation hollow rod body (3); By high-pressure slip-casting, slurries enter in stratum by oval slurry outlet, realize the anchorage effect of anchor pole.
Summary of the invention
The purpose of this utility model provides to overcome the defect of above-mentioned prior art existence the dentation high pressure slurry filling anchor bolt that a kind of structure is simple, easy to operate, cost-saving, improve anchored force just.
The purpose of this utility model is achieved by the following technical solution.
A kind of dentation high pressure slurry filling anchor bolt, comprises anchor head, splicing sleeve, dentation hollow rod body and oval slurry outlet; Hollow pointed anchor head is connected with splicing sleeve, and anchor head offers oval slurry outlet A; Splicing sleeve is connected with dentation hollow rod body, and splicing sleeve offers oval slurry outlet B; And oval slurry outlet C is offered on two sides of dentation hollow rod body.
Oval slurry outlet A described in the utility model, oval slurry outlet B, that oval slurry outlet C is all set to transverse is vertical, the slurries of high-pressure slip-casting and the overall contact area of anchor pole large, the high-pressure slip-casting slurries of the external surface of dentation hollow rod body can play the effect blocking anchor pole, and entirety improves anchor pole tensile strength, anchored force.
The utility model is symmetrical arranged two oval slurry outlets respectively on anchor head, splicing sleeve equidirectional; Two sides of dentation hollow rod body offer the oval slurry outlet C of 10.
The utility model is applicable to first to punch the stratum of grouting behind shaft or drift lining.
The purpose of this utility model is on traditional mooring rod technique basis, the outer surface structure of anchor rod body and slurry injection technique is improved, and reaches and improves the overall tensile strength of anchor pole.
A kind of dentation high pressure slurry filling anchor bolt technology described in the utility model is compared conventional anchor technology, and anchored force greatly improves, and can save the length of anchor pole, reduces the cost of anchor pole.
A kind of dentation high pressure slurry filling anchor bolt described in the utility model, by arranging oval slurry outlet on dentation hollow rod body, after grout cures, can play the effect blocking anchor pole, entirety improves the anchored force of anchor pole.
This detailed description of the invention has following beneficial effect: the advantages such as structure is simple, easy to operate, cost-saving, raising anchored force.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of dentation high pressure slurry filling anchor bolt, comprises anchor head 1, splicing sleeve 2, dentation hollow rod body 3 and oval slurry outlet; Hollow pointed anchor head 1 is connected with splicing sleeve 2, and anchor head 1 offers oval slurry outlet A4.1; Splicing sleeve 2 is connected with dentation hollow rod body 3, and splicing sleeve 2 offers oval slurry outlet B4.2; And symmetry offers oval slurry outlet C4.3 on two sides of dentation hollow rod body 3.
Oval slurry outlet A4.1 described in the utility model, oval slurry outlet B4.2, that oval slurry outlet C4.3 is all set to transverse is vertical, the slurries of high-pressure slip-casting and the overall contact area of anchor pole large, the high-pressure slip-casting slurries of the external surface of dentation hollow rod body 3 can play the effect blocking anchor pole, and entirety improves anchor pole tensile strength, anchored force.
The utility model is symmetrical arranged two oval slurry outlets respectively on anchor head 1, splicing sleeve 2 equidirectional; The symmetrical oval slurry outlet C4.3 offering 10 on two sides of dentation hollow rod body 3.
The utility model implementation step is: the first step, according to rock-bolt length and diameter, determines drilling depth and aperture, drilling; Anchor pole inserts in boring by second step; 3rd step slip casting, the oval slurry outlet by 1, on splicing sleeve 2 and dentation hollow rod body 3 body structure surface enters in the gap between anchor pole external surface and stratum by slurries, just completes the construction of anchor pole after cement slurry sets.
