Abstract
The invention discloses an anchor rod which consists of a backing plate, a baffle cover and a rod body, wherein a cavity is formed inside the rod body; a mortar inlet connected with the cavity is formed in the end part of the rod body; external threads are arranged at the end part of the rod body; a plurality of mortar overflow holes connected with the cavity are formed in the outer circumferential wall of the rod body and are uniformly arrayed along the axial direction of the rod body; internal threads correspondingly matched with the external threads are arranged on the baffle cover and are used for opening or closing the mortar inlet; the backing plate movably sleeves the rod body, and the upper end face of the backing plate can be supported against the lower end face of the baffle cover. According to the anchor rod, the defect that the anchor rod is easily extracted from cement mortar under the long-term action of an outside environment can be overcome.
Description
Technical field
The present invention relates to reinforcing side slope technique field, particularly a kind of anchor pole and adopt the solid anchor method of this anchor pole.
Background technology
A large amount of slope project is related in the construction of highway in China, railway and infrastructure, slope reinforcement is the important component part in this engineering, the reinforcement form extensively adopted at present is anchoring, but common anchor pole is under long-term external environment effect, easily extract from cement mortar, or extract together with cement mortar, thus lose anchorage effect, the stability and safety of side slope can not be ensured.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of anchor pole, thus overcome anchor pole under long-term external environment effect, the shortcoming of easily extracting from cement mortar.
For achieving the above object, the invention provides a kind of anchor pole, be made up of backing plate, door and the body of rod,
The inside of the described body of rod is cavity, is provided with the pulp inlet connecting described cavity in the end of the described body of rod, and offers at the periphery wall of the described body of rod extravasating hole that multiple and described cavity is connected;
Described door is connected with the described body of rod in the mode that can dismantle, and is used to open or close pulp inlet.
Described backing plate activity is placed on the described body of rod and the upper surface of this backing plate and can offsets with the lower surface of described door.
In technique scheme, described multiple extravasating hole is evenly distributed along the axis of the described body of rod.
In technique scheme, be provided with external screw thread in the end of the described body of rod, described door is provided with the internal thread with described external screw thread corresponding matching.
Another object of the present invention is to provide a kind of solid anchor method adopting above-mentioned anchor pole, thus overcome anchor pole under long-term external environment effect, the shortcoming of easily extracting from cement mortar.
For achieving the above object, the invention provides a kind of solid anchor method adopting above-mentioned anchor pole, comprise the following steps:
1) treat solid slope body and offer multiple anchor hole, the hole wall of described anchor hole offers and multiplely to stretch out and hole is starched in the expansion corresponding with multiple extravasating hole of the described body of rod;
2) the described body of rod is inserted described anchor hole, and make described multiple extravasating hole multiplely expand that to starch hole corresponding with described;
3) pour into cement mortar toward described pulp inlet, expanded to form excessive slurry toward described expansion slurry direction, hole by described extravasating hole after described cement mortar fills full described cavity;
4) be inserted in backing plate, and be screwed into the described body of rod by door described backing plate is reinforced.
Compared with prior art, the present invention has following beneficial effect: the anchor pole in the present invention and adopt the solid anchor method of this anchor pole, hole is starched in the expansion that cement mortar in anchor pole is overflowed in the body of slope by extravasating hole, form perforate to overflow slurry, together with the cement mortar in anchor pole, two-way reinforcement effect is played to Rock And Soil, not only increase the uplift resistance of anchor pole, thus ensure the safety of side slope, and there is the advantages such as construction is convenient, good economy performance.
