Grouting squeezing and expanding anchor rod device and construction method based on grouting squeezing and expanding anchor rod device
A grouting squeezing and expanding anchor rod device comprises an anchor rod, the anchor rod penetrates through a grouting pipe, the lower section of the grouting pipe is wrapped with a waterproof grout bundling bag, after anchoring, grouting is conducted in the grouting pipe through a grouting device at the top of the anchor rod, grout is discharged into the grout bundling bag from a grout outlet of the grouting pipe, surrounding soil is squeezed and expanded under the action of grouting pressure, and finally the grouting squeezing and expanding anchor rod is formed. The top of the anchor rod is anchored in the reinforced concrete foundation. According to the grouting squeezing and expanding anchor rod device, rotary jet grouting bottom expanding is not needed on the construction site, the investment of construction equipment is reduced, and the construction efficiency is improved; and the anchoring section rod body structure is simplified. The invention further discloses a construction method based on the grouting squeezing and expanding anchor rod device. The construction method mainly comprises drilling implantation and static pressure implantation.
一种注浆挤扩锚杆装置，其包括锚杆，锚杆贯穿注浆管，在注浆管下段包裹防水束浆袋，待下锚以后，通过锚杆顶部注浆装置，对注浆管内进行注浆，浆液自注浆管出浆孔出浆至束浆袋内，在注浆压力作用下挤扩四周土体，最终形成注浆挤扩锚杆；锚杆顶部锚固在钢筋混凝土基础中。本申请的注浆挤扩锚杆装置在施工现场无需采用旋喷扩底，减少了施工设备投入，提高施工效率；简化锚固段杆体构造。本申请还公开了基于注浆挤扩锚杆装置的施工方法，所述施工方法主要包括钻孔植入与静压植入。
