Abstract

The utility model relates to a soil building constructing machine, particularly a hole sealing device which can continuously grout cement. A slurry sucking piece is arranged in a housing body by a vertical shaft, and a pedestal is fastened on the housing body by screws. The lower end of the vertical shaft passes through the pedestal, and a gland is fastened on a gland by screws. The glands are fastened on the housing body. Therefore, the utility model can grout under constant design pressure, and avoid the phenomena that slurry in holes precipitates, solidifies and drains.

Description

Stir cycle grouting aperture sealer

The utility model relates to a kind of civil engineering machine, but the cemented aperture of particularly a kind of continuous irrigation sealer.

Up to the present cycle of higher pressure grouting is an emerge science, goes back imperfection, and some technology and process equipment problem are still waiting research and perfect, resembles cycle of higher pressure grouting aperture locking device, the dependency relation of high pressure grouting screen slurry time and pressure etc.Especially cycle of higher pressure grouting aperture locking device directly influences the effect of high pressure grouting.Existing high pressure grouting aperture locking device is to adopt glueballs sealing method, under design pressure, can not rotate more and can not move up and down.Because the setting rate of cement paste is accelerated in high pressure grouting, admittedly so the situation of boring take place often, for reduce solid brill, a lot of engineering adopts regularly step-down to rotate in grouting construction, carries drilling rod, even now, solid brill still happen occasionally, Goddess of Mercy Pavilion reservoir engineering total grouting drilling depth 58 on September 1st, 1 1993 on April 1st, 1991 construction only, 246m takes place to bore admittedly 89 times, loss drilling rod 5,664m, direct economic loss reaches 601,440 yuan.

The inventor has applied for the utility model patent of " cycle grouting aperture locking device " on October 11st, 93 for this reason, and is authorized to, and its patent No. is 93229419.7.

Also there is following shortcoming in " cycle grouting aperture locking device " though can reach the requirement of stirring cycle grouting fully on construction technology;

1. because it adopts gear drive, so the structure more complicated, volume is big, the weight TV university, and manufacturing cost is also than higher.Installation and removal are difficulty relatively;

2. because it has adopted side priming power, so in when operation less stable, and because concentricity is difficult to control, so the rate that breaks down increases.

But the purpose of this utility model is to provide a kind of stirring cycle grouting aperture sealer of continous pouring cement paste, both through vertical shaft the suction lodicule is housed, and base was gone here and there in the vertical shaft lower end, and gland is fastened on the housing; By this device grouting can be carried out under constant design pressure.

The purpose of this utility model realizes by following technical measures:

It comprises housing, vertical shaft, suction lodicule, base, gland, in the described housing, through vertical shaft the suction lodicule is housed, and base is fastened on the housing through screw, and base was gone here and there in the vertical shaft lower end, and on gland, gland is fastened on the housing gland through screw in compression; The suction lodicule that installs on the vertical shaft communicates with inlet pipe; Base one side is provided with return pipe, vertical shaft through bearing with fixing and radially be provided with sealing ring respectively; The vertical shaft upper end has the taper screw socket, and the lower end is a conical screw.

Advantage of the present utility model and good effect are:

Stir cycle grouting aperture sealer, except the function that can reach cycle grouting aperture locking device, also possess following advantage:

1. by adopting the direct transmission Grout-jetting pipe of rig vertical shaft, aperture locking device structure has been simplified in the cancellation gear drive, has dwindled volume, reduces weight, has reduced cost, mounts and dismounts all more convenient.

2. owing to direct transferring power, strong guarantee rig vertical shaft and the concentricity of penetrating tubulature reduce rate of breakdown.

3. owing to adopt the pulp absorbing pump principle, the strong grout pump that helps increases pressure in running.

Description of drawings is as follows:

Accompanying drawing of the present utility model is the overall structure sectional view.

Below in conjunction with the accompanying drawing illustrated embodiment the utility model is done further detailed description: a side of housing 1 is provided with inlet pipe 15, gland 14 is connected with housing 1 by hexagon socket head cap screw 10, establish XY type sealing ring 8 in the gland 14, gland 11 is connected with gland 14 by soket head cap screw 12, bearing 13 is equipped with in gland 11 inboards, be provided with XY type sealing ring 16 in the housing 1, base 5 is connected with housing 1 by soket head cap screw 7, base 5 upper inner are equipped with bearing 18, the bearing bottom is provided with XY type sealing ring 19 in the base inboard, base one side is provided with return pipe 6, vertical shaft 2 upper ends are provided with the screw socket 4 that is connected with the rig vertical shaft, vertical shaft 2 middle parts are provided with inhales lodicule 3, vertical shaft 2 lower ends are provided with the conical screw 20 that is connected with Grout-jetting pipe, and slurries pass vertical shaft 2 lower ends by inlet pipe 15 suction lodicules 3 and go into grout hole by Grout-jetting pipe, and grouting back residue slurries return by return pipe 6 by the space between the Grout-jetting pipe outside and the grout hole, at the same time, vertical shaft 2 drives the Grout-jetting pipe rotation by accepting power with rig vertical shaft connector 4.Stir the cycle grouting overall process thereby reach.

Gland 14 seals by O type sealing ring 9 with housing 1, base 2 seals by O type circle 17 with housing 1, bearing 13 is pressed in vertical shaft 2 upper ends, bearing 18 is pressed in the lower end of vertical shaft 2, vertical shaft 2 is by 8 sealings of XY type sealing ring with gland 14, vertical shaft 2 is by 16 sealings of XY type sealing ring with housing 1, and vertical shaft 2 is by 19 sealings of XY type sealing ring with base 5.

During use, slurries pass vertical shaft 2 lower ends by inlet pipe 15 suction lodicules 3 and go into grout hole by Grout-jetting pipe, grouting back residue slurries return by return pipe 6 by the space between the Grout-jetting pipe outside and the grout hole, at the same time, vertical shaft 2 drives the Grout-jetting pipe rotation by accepting power with rig vertical shaft connector 4.Stir the cycle grouting overall process thereby reach.
