管縫式錨桿又名縫管錨桿,該錨桿是主動(dòng)加固圍巖全錨固立即承載等優(yōu)點(diǎn),安裝于比管徑稍小的鉆孔中,可立即在全長(zhǎng)范圍內(nèi)對(duì)孔壁施加徑向壓力防止圍巖下滑.在爆破振動(dòng)圍巖位移情況下,錨固力明顯增大,支護(hù)效果更加理想.

slit wedge tubing bolt , also known asseam anchor bolt has many advantages such as consolidate asurrounding rock on self"s own initiative, active reinforcementanchorage and immediately bearing etc. the bolt is installed in ahole which has smaller diameter than it. it can immediately imposefull range radial pressure on the wall of the hole to prevent rockfall. in case of blasting vibration displacement of surroundingrock, anchoring increases significantly, and supporting effect isideal.

該產(chǎn)品主要銷往澳大利亞、美國(guó)、印尼、菲律賓等國(guó)家。

the products are mainly exported toaustralia, the united states, indonesia, the philippines and othercountries.

管縫式錨桿鉆孔孔徑推薦計(jì)算方法：

the best consumption of feed tubediameter drilling anchor

巖層中：

the rock stratum

鉆孔直徑=（0.9-0.95）×錨桿直徑

borehole diameter=（0.9-0.95）×bolt diameter

錨桿鉆孔深度:錨桿長(zhǎng)度+100mm

anchor drilling depth: anchorlength+100mm

鉆孔偏斜率＜1%

drilling partialslope＜1%

煤層中：

coal seam

鉆孔直徑=(0.9-1.00)×錨桿直徑

borehole diameter =（0.9-1.00）×bolt diameter

錨桿鉆孔深度:錨桿長(zhǎng)度+200mm

anchor drilling depth: anchorlength+200mm

鉆孔偏斜率<1.5%

drilling partialslope＜1.5%

使用方法

method of application

(1)依據(jù)設(shè)計(jì)要求確定錨桿孔位，用鉆機(jī)具打孔。

according to the re ofdesign, drill a hole with punching

(2)用壓風(fēng)吹盡孔內(nèi)巖粉。

use wind pressure to blast the rockpowder of the hole

(3)桿體裝上錨盤，用沖擊鉆將錨桿打入孔中。
