Advantage of the present utility model: this technology makes and to carry on construction work at night, the navigation on daytime becomes possibility, and construction and is not stayed any vestige flexibly, rapidly, reduces the economic loss of suspending, and has guaranteed that the airport normally opens the navigation or air flight.Be applicable to Large Square, large tracts of land sandy gravel basic unit terrace.
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is that schematic diagram is arranged in the job site of using this equipment;
Fig. 2 is the structural representation of airfield runway basic unit grouting and reinforcing construction equipment;
Fig. 3 is the structural representation of pressed sealing device in the airfield runway basic unit grouting and reinforcing construction equipment;
Fig. 4 divides the slurry device and send slurry pipe connection diagram in the airfield runway of the present invention basic unit grouting and reinforcing construction equipment.
Embodiment is an example with the airfield runway basic unit grouting and reinforcing construction in the Capital Airport as shown in Figure 1, construction sequence:
(1). cloth hole, slip casting diffusion radius 1-3 rice, every plate 5 holes;
(2). boring, earlier with core-drill(ing) machine boring, submersible creeps into 10～15cm, withdraw from drilling rod and take out core, simultaneously with instrument during operation trickling ground and hole in water clean out.Be drilled into below the panel with the air pressure gun operation afterwards, should verify following cable of pavement slab and pipeline situation before the pore-forming;
(3). clear hole, with the clear hole of device, clear hole, clear hole device is connected with air compressor machine, with spare and the residue in the high pressure draught purge hole, for avoiding the hole of collapsing;
(4). grouting equipment is installed, slurries are after stirring, send in the branch slurry device through slush pump pressure, divide the slurry device to be divided into five slip casting outlets, slurries all will pass through the flow directions such as flow transmitter, valve switch and send in the slurry pipe, send the slurry pipe to connect grouting tube, are respectively equipped with pressure meter and safety relief valve simultaneously near the slip casting outlet, with convenient slurries pressure is monitored at any time, guarantee construction and device security.Slurries are when flowing through flow transmitter, the inductor of flow transmitter is to the mobile generation induction of slurries, and it is changed into the mainboard that the signal of telecommunication transfers to corresponding flow meter, mainboard transfers to display screen after handling through data, display screen shows corresponding instantaneous velocity and the flow that send in the slurry pipe, also transfer to Acquisition Instrument through the mainboard data processed simultaneously, after Acquisition Instrument reads data, editor, be stored in the IC-card, card reader reads data again and enters the private database of computer from IC-card, editor's arrangement back is printed and bound into book form.
(5). the slip casting pressed sealing device is installed, pressure meter and flowmeter;
After hole depth adheres to specification, can insert grouting tube, seal plug-hole,, pressed sealing device is installed then in plugging device loam cake one annular iron plate with plugging device.Slurries must be with the grouting tube sealing and fixing in injected hole before injection, and cover top cement plug packing ring in grouting tube puts O-ring seal afterwards earlier, overlaps top cement plug again, inserts in the injected hole then.One location bolt is set at the position of the about 200mm of distance injected hole, to compress base sleeve then behind positioning bolt, the horizontal base head is buckled on the plug packing ring, the balance cushion block is pressed on one's body the pedestal by positioning bolt, step up crank and positioning bolt and be pressed on the balance cushion block, screw crank, just be pressed on the plug packing ring by the horizontal base head by screwed connection, plug is contacted, to reach enough slips casing by pressure with the sealing of slip casting aperture.
(6). slip casting.Allowing under the pressure of slip casting that adopt the mode of flow-control to give slip casting, grouting mode is a cycling element with every panel, every cycling element is by the slip casting simultaneously of 5 holes, and slip casting is operation from bottom to top, at twice slip casting, insert floral tube slip casting for the first time earlier, for the second time slip casting once more behind the tube drawing 5-10cm.Twice slip casting is not less than 5-10 minute blanking time.Make slurries filling widely in the hole or space of rubble and aggregate chips basic unit, and continue, produce a desired effect with gelling.In the time of slip casting, utilize special flow Acquisition Instrument reading, write down each hole grouting amount of every block of plate and printing.Every plate slip casting time should be controlled according to grouting pressure, pavement slab lifting amount and the excessive slurry situation of plate seam, and when grouting pressure remained on certain numerical value, grouting amount no longer increased, and can stop slip casting.For avoiding slurries to run off, grouting sequence should be during construction: earlier runway centerline outside pavement slab is carried out slip casting, seal both sides, do not exosmose in the time of can guaranteeing the slip casting of runway middle part like this, help the extruding of slurries and closely knit, and then middle part slip casting.
Injection slurry be the straight cement slurries and antifreeze morning strong composite water-reducing agent, water/binder ratio is 0.8.Grouting pressure is not more than 2.5MPa, when pressure surpasses, stop 5-10 minute after, continue slip casting.
(7). the shutoff injected hole.After grouting with plunger finishes, should in time give the sealing of hole operation, promptly cram boring to the aperture with super-early strength cement 525R, aperture palpus levelling is for preventing the frost heave in winter, than the low 3-5mm of original ground.
(8). the cleaning of road face.In the time of panel slip casting, foreign material such as rubble that will go out cement core, clear Kong Qing and aggregate chips, excessive cement grout thoroughly clean, and the preceding road face that guarantees to accomplish to hand over to the next shift does not stay more any hidden danger that jeopardizes aircraft flight.In the grouting and reinforcing construction of Capital Airport airfield runway basic unit, normally open the navigation or air flight daytime, the construction of marching into the arena night.Compare about 2.36 hundred million yuan of minimizing economic loss with the construction of suspending fully.
A complete set of construction equipment all is automobile-carried formula, comprises boring a complete set of equipment and slip casting a complete set of equipment.The boring a complete set of equipment mainly comprises core-drill(ing) machine, air pressure gun, portable electric hammer, clear hole device, pneumatics locomotive 1, generating locomotive 2, water tender 3 and lighting etc.The slip casting a complete set of equipment mainly comprises airfield runway basic unit grouting and reinforcing construction equipment, grouting parameter test and analysis process system test carriage 4, cleaning equipment, settlement observation instrument automatically.
