Description

Foundation pit anchor bolt supporting device Technical Field The application relates to the technical field of anchor rods, in particular to a foundation pit anchor rod supporting device. Background The anchor rod has very wide functions and can strengthen the main body of a slope, a tunnel, a dam body, a foundation pit and the like. The anchor rod is used as one of the main support forms of underground engineering and rock slopes, and plays an important role in maintaining the stability of civil engineering. The prior patent (publication number: CN 212153401U) discloses a foundation pit supporting anchor rod, which comprises a rod body and a rod core, wherein the rod body is of a hollow structure, the rod core is slidably connected into the rod body, one end of the rod body is an anchor point, the other end of the rod body is a threaded end, an anchor rod cap is in threaded connection with the threaded end, one end of the rod core extends out of the threaded end, a plurality of anchor holes are formed in the rod body, anchor nails are slidably connected in the anchor holes, a sliding table matched with the anchor nails is arranged on the rod core, the height of the sliding table is larger than the distance from the anchor nails to an outlet of the anchor holes, and one side of the sliding table facing the anchor nails is an inclined surface. The utility model has the advantages that the anchoring nails are retracted into the anchoring holes, the smoothness of the rod body surface is maintained, the friction force is reduced when the anchoring nails are inserted into the holes, the anchoring nails are convenient to insert, the rod core is pushed after the anchoring nails are inserted, the sliding table pushes the anchoring nails to extend out of the anchoring holes, the operation of the device is convenient, the insertion is convenient, and the anchoring is firmer. The anchoring nail of the anchor rod is retracted into the anchoring hole, the smoothness of the surface of the rod body is kept, friction force is reduced when the anchoring nail is inserted into the hole, the anchoring nail is convenient to insert, the rod core is pushed after the anchoring nail is inserted, the sliding table is pushed to extend out of the anchoring hole, the device is convenient to operate, insertion and anchoring are more firm, but in the using process, the anchoring nail is mainly penetrated into surrounding soil to improve resistance, the pulling resistance is lower, in the using process, the internal humidity cannot be monitored, and the functionality is insufficient. Disclosure of utility model Aiming at the defects of the prior art, the application provides a foundation pit anchor bolt supporting device which has the advantages of tttt and the like and solves the problems in the background art. The foundation pit anchor bolt supporting device comprises an anchor pipe, wherein the outer surface of the anchor pipe is provided with threads, the left end of the anchor pipe is provided with an anchor mechanism, the anchor mechanism comprises an anchor sleeve, the anchor sleeve is fixedly connected with one end of the anchor pipe, a group of separation seams are formed in the outer surface of the anchor sleeve, the outer surface of the anchor sleeve is fixedly connected with a plurality of groups of resistance ribs, the cross section of each resistance rib is triangular, and the sharp end of each resistance rib faces the direction far away from the anchor pipe; The inner thread of anchor pipe is connected with the filling tube, the left end fixedly connected with toper platform of filling tube, toper platform and filling tube are in the same axis, the surface fixedly connected with of toper platform is a set of flaring piece that is circumference and arranges. Through above-mentioned scheme, through designing unique anchoring mechanism, including the anchor cover, separation seam and triangle form resistance rib, can reduce the resistance when the anchor pipe inserts soil, and when the toper platform promotes the outside expansion of anchor cover with the flaring piece, resistance rib can increase by a wide margin with the area of contact of foundation ditch soil, and carry out the filling concrete through the cooperation filling tube, thereby show the resistance to plucking performance that improves strutting arrangement, ensure the stability of foundation ditch support, the left surface fixed connection of backing plate has a set of thorn pole, and at thorn pole internally mounted humidity monitoring sensor, can real-time supervision foundation ditch soil's humidity change, provide important data support for the safety control of foundation ditch, help in time discover and handle potential safety hazard, right side contact early warning nut at conventional nut, when strutting arrangement appears not hard up, early warning nut can send early warning signal, remind relevant personnel in time take measures to consolidate, there
