Embodiment Construction

[0010] Such as figure 1 and figure 2 As shown, the present invention mainly comprises: steel pipe 1, anchor grab top seat 2, piston propulsion body 3, strut 4 and anchor grab 5, and its connection mode is: anchor grab top seat 2 and steel pipe 1 are connected by fixed pillar 12, four The two ends of the root strut 4 are respectively connected to the strut base 10 and the anchor grab 5 of the piston propelling body 3 by movable pins. The struts 4 are connected, and the anchor head rear portion is provided with a connecting hole to be connected with the anchor cable 7.

[0011] The tail of the steel pipe 1 is provided with a pressure grouting hole 6, and there are four reserved holes 8 on the upper part of the steel pipe 1. Pressure grouting from the pressure grouting hole 6 makes the anchor grab 5 open, and the slurry continues to enter through the four reserved holes 8. Anchor hole. Anchor grab top seat 2 is provided with four bearings. The piston propelling body 3 is com...

Abstract

This invention includes: thin wall steel tube, fluke top seat, piston propeller, bar and fluke in which the fluke top seat is fixedly connected with the thin wall steel tube, both ends of the bar are connected to its base seat of the piston probeller and fluke separately by flexible pins, the anchor head is linked to the fluke top seat by pins and middle of the fluke is linked with the bar, and connection holes connect the anchor chain at the back of the anchor head. Using the character of large fixed area and powerful force of fluke, this invention provides pulling resistance like anchor, in operation the back of anchor head is connected with the chain then put in anchor eyes to grout with high pressure from thin-wall steel tube to force the fluke open into the anchor eye wall to provide anchor force.

Description

technical field [0001] The invention relates to an anchor head of a soil anchor, in particular to a ship anchor type grouting expansion type soil anchor head, which belongs to the field of soil anchoring. Background technique [0002] Rock-soil anchoring technology can fully tap the energy of rock and soil itself, use its own strength and self-supporting capacity, ensure construction safety and structural stability, save engineering materials, and thus achieve significant economic benefits. The anchoring method in the natural soil layer is mainly drilling and grouting, which is generally called grouting anchor, and there are other forms such as soil nailing and wall anchoring. The anchor rod in the grouted soil layer is composed of an anchor rod (anchor cable), a free section, an anchor section, an anchor head, and a cushion block. The anchor section and the anchor head are the providers of the pull-out force, and their performance is related to the effect of the anchor rod...
