Abstract
The utility model relates to a big head anchor rod drill machine, which comprises a jacking system, a hydraulic power, a control loop, a chassis, a running mechanism and a revolving guidance system which is composed of a power head and a spiral drilling tool. The power head is composed of an electric motor and a transmission case. The spiral drilling tool comprises a guide bar, a drill head and a drill stem with vane. The interior of the drill stem is provided with a center bore. The position which is close to the drill stem is provided with at least two symmetrically arranged air spouts which are communicated with the center bore. The upper part of the drill stem is provided with a slip casting device. When the drill stem goes up in rotation or goes down in rotation, the drill machine can cut clay which is around the hole by ejecting the cement mortar by the air spout to cause the drill machine to form an enlarged bore part. The operation of a big head anchor rod can be finished by one drill machine.
Description
The utility model relates generally to a kind of rig, specifically relates to the spiral drilling machine that a kind of pressure grouting anchor rod construction method uses.
Anchor pole is a kind of tension member that the Foundation Design excavation construction is used, and the one end is connected with engineering foundation ditch retaining wall, and the other end is fixed in the underground soil layer, to bear soil layer or water pressure to the thrust that the shelves cob wall causes, keeps the stability of soil layer or building.
The processing step of existing anchor rod construction method is:
1. hole to projected depth with auger;
2. put into the reinforcing pull rod that the next door is fixed with the Grouting Pipe of plastic pipe or steel pipe;
3. by the Grouting Pipe grout injection, generally need perfusion three times and health.
The anchor pole of constructing like this is because of the frictional force between anchor pole and the undisturbed soil is little, and the pulling capacity of bearing is low.In order to improve anti-pulling of anchor bar, need to increase the quantity and the length of anchor pole, brought great difficulty to construction, increased operating expenses, delayed programming.
In recent years, along with highrise building, the Deep Foundation Excavation engineering progressively increases, and basic retaining wall is more and more higher, and the anchor pole pulling capacity of making of existing job practices is lower, does not satisfy design requirement far away.For this reason, people adopt the long anchor pole that steel hinge rope is made more.Though this long anchor pole anchored force is bigger, complex process, constructional difficulties, because the geology soil layer changes greatly, and anchored force can not scale up with the increase of pull bar length, although rock-bolt length increases much sometimes, anchored force increases very little simultaneously.
The inventor has invented a kind of large-head anchor rod and job practices thereof for this reason.This large-head anchor rod is shown in Fig. 1～2.To make its drawknot together with the horizontal waist rail of making by i iron or channel-section steel 2 between the barricade concrete pile 1 in foundation ditch.These waist rails 2 will be used large-head anchor rod 3 anchorings.The tail end of the reinforcing pull rod 31 of large-head anchor rod 3 of the present utility model is shaped on down wing 32, and the wing that falls can be 3,4 or a plurality of, and the grouting back is combined into one with cement paste and forms anchor pole enlarged head 33.During the skyhook head, between concrete pile 1 and waist rail 2, load onto voussoir 4, load onto backing plate 5 at the head of anchor pole reinforcing pull rod then, be screwed into nut 6 again, horizontal waist rail 2 can be fixed, make barricade concrete pile drawknot together.Anchor pole adds when giving stress, in the time of available drawbench tension reinforcing pull rod 31, is screwed into nut 6.
At first will form diameter at the bottom of the hole that enlarges during the construction of this large-head anchor rod in the bottom of boring, so that put into the reinforcing pull rod by inventor's invention of an end band wing, the fills with water gray scale is 0.5～0.6 neat slurry then, forms big capitiform anchor pole.And existing spiral drilling machine the time can only form an identical circular hole of diameter up and down in boring, can not form diameter at the bottom of the hole that enlarges in the bottom in hole, can not satisfy the requirement of large-head anchor rod construction method.
The purpose of this utility model is to provide a kind of large-head anchor rod rig of large-head anchor rod construction method use.
Large-head anchor rod rig of the present utility model, comprise jacking system, hydraulic power and control system, chassis and walking mechanism and by unit head, the revolution guidance system that spiral drill is formed, described unit head is by motor, gearbox is formed, spiral drill comprises guide peg, the drilling rod of drill bit and band blade, in described drilling rod, be provided with centre bore, be provided with the nozzle that communicates with described centre bore of at least two symmetric arrangement near the drill bit place at drilling rod, be provided with slurry casting machine on described drilling rod top, this slurry casting machine comprises that is fixed on a shell and the cased rotor that links to each other with drilling rod by guide peg that has injected hole on the borer frame, and this rotor has the hole that communicates with described injected hole and drilling rod centre bore.
The advantage of large-head anchor rod rig of the present utility model is to be provided with nozzle near the drill bit place, in drilling rod rotary lifting or decline, can penetrate the cement paste cutting hole earth on every side of certain pressure by nozzle, make it to form an aperture part that enlarges, can finish the construction of large-head anchor rod with a bench drill machine.
Other details of the present utility model and advantage can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings, wherein:
Fig. 1 is a large-head anchor rod anchoring status schematic diagram;
Fig. 2 is the left side view of Fig. 1;
Fig. 3 is the structural representation of the utility model large-head anchor rod rig spiral drill and coupled slurry casting machine;
Fig. 4 is the partial enlarged drawing of Fig. 3.
With reference to Fig. 3～Fig. 4.Large-head anchor rod rig of the present utility model is the improvement of making on the basis of known spiral anchor rod rig, this jumbolter comprises known jacking system, hydraulic power and control system, chassis and walking mechanism and the revolution guidance system of forming by unit head, spiral drill 13, unit head is made up of motor, gearbox, hydraulic pressure pipe slips, spiral drill 13 comprises drill bit 14, the guide peg 12 that the drilling rod 16 of band blade 15 links to each other with the top with drilling rod 16, the hydraulic pressure pipe slips of guide peg 12 usefulness unit heads blocks by its rotation of Motor Drive.In drilling rod 16 and guide peg 12, be provided with and be provided with the nozzle 18 that communicates with hole 17 by the centre bore 17 of cement paste near drill bit 14 places.Nozzle shown in the figure is 2, and nozzle 18 is pressed into earlier in the nozzle body 18 ', is screwed in then on the drilling rod 16, also nozzle 18 directly can be welded on the drilling rod 16.Nozzle in fact also can be a plurality of.Top at guide peg 12 is connected with slurry casting machine 19 by the movable joint 28 with centre bore.This slurry casting machine 19 comprises that is fixed on a shell 20 that has injected hole on the borer frame, a rotor 22 that links together with movable joint 28 usefulness screw threads 21 is housed in shell 20, between rotor 22 and shell 20, ball bearing 23 is housed, but rotor 22 opposite shell 20 are rotated.There is the hole 24 that communicates with drilling rod centre bore 17 inside of rotor 22.The top of shell 20 covers with end cap 25, and end cap 25 usefulness screw threads and shell 20 are fixed together.End at end cap 25 links to each other with bayonet coupling 26 by screw thread, and the inlet 27 of bayonet coupling 26 links to each other with the slip casting high-pressure rubber pipe, and the centre bore of bayonet coupling 26 communicates with the hole of rotor 22 by the slip casting centre bore on the end cap 25.Between end cap 25 and rotor 22, sealing ring 30 is housed.29 is blocks of rigid bearing 23 usefulness among the figure.
