Description
Technical field:
The present invention relates to the rapid construction Apparatus for () and method therefor of pile foundation construction process, particularly relate to a kind of rapid construction, save the construction equipment of jet grouting of stiffening piles of operation and the rapid constructing method based on this equipment.
Background technology:
Tradition often adopts jet mixing drill bit precession on one side one side inject high pressure cement paste to make stiffening pile; The drill bit adopted is three-wing bit; The course of work is separated as an independent process process of placing steel strand, carrying out aperture slip casting subsequently, easily causing middle part to have hole, and there is following shortcoming:
Labor intensive; Speed of application slowly; Mechanical wear quickly; Lose time; Drill bit and drilling rod are difficult to change; Operating process is numerous and diverse, and program is very many; Be not easy cleaning; Need very high specialist.
Summary of the invention: the object of invention: in order to provide a kind of convenient and quick construction, greatly simplifying construction process, easily cleaning, greatly shorten the engineering time, speed of application is fast; Use manpower and material resources sparingly, reduce mechanical loss, easily change the construction equipment of jet grouting of stiffening piles of construction parts and the rapid constructing method based on this equipment.
In order to reach as above object, the present invention takes following technical scheme: power rail is connected with drill bit shaft by pressure bearing, drill bit shaft has nozzle, and described pressure bearing is divided into pressure bearing power side, pressure bearing running part and fixation side, and fixation side is close to mutually with end tray.
Further technical scheme of the present invention is: described fixation side is surperficial for there being the surface of the thrust of increasing friction force near end tray.
Further technical scheme of the present invention is: described drill bit shaft bit part and bar portion are that drill bit thread is connected.
Further technical scheme of the present invention is: described drill bit shaft is connected with pressure bearing and is threaded for carrying bar.
Further technical scheme of the present invention is: described end tray has more than one extruding anchor, in the middle part of extruding anchor, steel strand are fixed thereon, has perforation in the middle part of end tray.
Further technical scheme of the present invention is: described extruding anchor equal distribution is on end tray.
Further technical scheme of the present invention is: the drill bit in described drill bit shaft is for conical.
Utilize the construction method of above-mentioned device: its scheme is: comprise following steps:
● install: the perforation in the middle part of end tray is arranged on bit part, fixation side is close to mutually with end tray;
● churning is advanced: nozzle ejection highly pressurised liquid carries out cutting packing, and constantly advances under thrust, and now slip casting is constantly carried out;
● exit, lay and slip casting: exited by drill bit, now hold tray to be placed in inside, seal with slurries, now stiffening pile has been constructed.
The further technical scheme of construction method of the present invention is: described churning is advanced and first sprayed water, rear water-spray type slurry.
In process of the invention process: the perforation in the middle part of end tray is arranged on bit part, and drill bit shaft is connected with pressure bearing and is threaded for carrying bar, hold tray to be arranged on and carry on bar, fixation side with hold tray and be close to mutually; Bit part is needed constantly to rotate in churning and the process of creeping into, now power transmission is come by three parts of pressure bearing, because motive bearing has fixation side, therefore tray is held can not to rotate along with it, therefore tray is held to advance conveniently, and be advanced further propelling with steel strand, steel strand one-off construction can be put in place.
In the process of construction, first from nozzle spray, like this high-pressure water cutting becomes some mud, gunite subsequently, because the ratio of cement paste is great, mud can be extruded, can effective implemention perfusion and reinforcement.
Adopt the construction equipment of the jet grouting of stiffening piles of as above technical scheme and the rapid constructing method based on this equipment, there is following beneficial effect:
1. need less people's operation, and labour intensity reduces greatly, saves manpower;
2. speed of application quickly, disposable steel strand can be delivered to position, can't produce distortion, and this problem was once the technical barrier that industry inside is generally acknowledged, it is generally acknowledged that precession and reinforcement can not a step complete;
3. mechanical wear reduces greatly, and multi-pass operation originally needs repeatedly to run, and often goes wrong in the cement and earth environment of complexity, and this technique is few, stable with equipment operation, and mechanical wear reduces naturally relatively;
4., while greatly simplifying operation, can greatly save time;
5., because of releasable connections such as invention employing are threaded, this drill bit and drilling rod are changed easily, carry out cleaning also being very easy to when nozzle gets clogged;
6. operating process is simple, and program is considerably less, greatly reduces operation easier;
7. because removable, so easily clean; Operation does not need very high specialist.
Accompanying drawing illustrates:
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
Fig. 1 is the structural representation that the power rail of invention is connected with bit part;
Fig. 2 is end tray of the present invention and strand structure schematic diagram;
Fig. 3 is the right diagram of end tray structure of the present invention;
1. wherein: power rail; 2. pressure bearing power side; 3. pressure bearing running part; 4. fixation side; 5. carry bar to be threaded; 6. nozzle; 7. drill bit thread connects; 8. drill bit; 9. steel strand; 10. end tray; 11. extruding anchors.
