Abstract
The present invention relates to a quadruple trunk high-pressure uniform injection method for charging foundation hardening agent, and is characterized by that each valve of air reservoir of air compressor, etc. is divided into two branches, and each branch is individually combined with two pipelines of rotating joint of the quadruple trunk so as to make the pressurization flow paths of pressurized gases jetted from upper and lower nozzles be different from each other, and can randomly regulate injection pressure difference between pressurized gases jetted around the upper and lower nozzles.
Description
The present invention relates to soft groundsill reinforcing, construction structure basis etc. is the hardening of ground agent pouring construction method that purpose is constructed, and relates in particular to the high-pressure uniform gunite that can form the uniform high-quality ground stabilization body of typing.
For a long time, people have adopted all construction methods, attempt to seek the high gunite of hardening of ground agent.About this point, epoch-making excellent triple pipe construction method has appearred recently, also summarized so at first this conventional example is shown in Fig. 6.
On the monitor sidewall of perfusion drilling rod 50 front ends of three streams that are installed on polymeric configuration, wear towards each drilling rod internal flow path and in the upper nozzle 53 and the lower nozzle 54 of the polymeric configuration of jet polymerization, go out gas-pressurized from each around nozzle ejection, eject high-pressure water from the top core nozzle, from bottom core nozzle ejection super-pressure hardener.
Each jet flow thing that is gas-pressurized, high-pressure water, super-pressure hardener, use air compressor, high-pressure hydraulic pump, grout pump etc. respectively, steel pipe 56, triple pipe swivel 51 are being situated between, be pressed into drilling rod 50 internal flow paths from the outside, but up and down the gas-pressurized of nozzle ejection all via same stream.
Make the hardening of ground agent device for casting that possesses above-mentioned formation drop to the stage of prescribed depth, its revolution is being risen while make it spray various jet flow things.Therefore, the high-pressure water that pressurized gas encased around upper nozzle 53 sprayed on one side the underground grogs of this disturbance on one side causes artificial space, is filled up by the super-pressure hardener that lower nozzle 54 is sprayed with that at this space part.
Certainly, the gas-pressurized that sprays around two nozzles is regarded as one of indispensable factor investing on the excellent effect of so-called air-lift unit effect.
Specifically, the high-pressure water that the pressurized gas on every side that upper nozzle 53 sprays encases utilizes the lifting effect of its gas and pressure to extend to a distant place, disturbance, removal, washing impurity arriving distance.Therefore and the mud that produces etc., then because the high pressure effect of gas, and be discharged from ground (this just is called the air-lift unit effect).
Then, again by around spraying being the super-pressure hardener that gas-pressurized encased, make hardener force to be filled into the tiny front end of the high people of void content for the space, do not waste the power of top jet flow thing, and the effect of one about guaranteeing, make great efforts to improve the hardener filling rate simultaneously, guarantee construction reliability, to cause the underground hardened layer of major diameter.
According to the method described above, can improve the integrated effect of up and down jet-action, prolong the arrival distance of water under high pressure and hardener, make hardener can arrive the tiny space of distant place front end, improve the replacement ratio between mud and hardener, and can guarantee the reliability of constructing.
But pour into and have a problem to solve on this aspect guaranteeing high efficiency.That is, up and down around the mutual pressure differential of the gas-pressurized of nozzle ejection.
Come by force feed with the same stream of gas-pressurized in drilling rod that air compressor etc. is pressed into, it is seemingly natural therefore to produce differential pressure up and down between nozzle, is suitable trouble but will carry out this adjusting, sometimes even very difficult.
Certainly as if, solution such as nozzle diameter difference up and down etc. has a lot since but gas-pressurized via same stream, above-mentioned differential pressure problem always takes place, and regulates trouble and also is difficult for removing.
Therefore, purpose of the present invention is exactly will provide a kind of can adjust the new construction method around the gas-pressurized expulsion pressure that nozzle sprayed of nozzle up and down easily, solves above-mentioned differential pressure problem fully.
In order to reach above-mentioned purpose, the inventor is provided with the force feed stream around the gas-pressurized of nozzle ejection up and down respectively, changes pour into drilling rod as the quadruple pipe into.
Specifically, as shown in Figure 1, the valve of air compressor gasholder is divided into two branch roads respectively, every two pipelines that are linked to quadruple pipe swivel respectively.On the other hand, high-pressure water, super-pressure hardener also are pressed into two pipelines of residue of quadruple pipe swivel.Like this, four kinds of jet flow things respectively via four different streams in the perfusion drilling rod by force feed.Adjust discharge pressure by the valve of regulating on the air compressor, also just can freely adjust the expulsion pressure up and down (emitted dose) of gas-pressurized.
In addition, it is also conceivable that and prepare two air compressors, respectively air is pressed into by each.
Detailed situation recited above is shown in accompanying drawing, and further describes in an embodiment.
Method as described above is up and down around the as easy as rolling off a log adjustment of expulsion pressure of the gas-pressurized of nozzle ejection.Certainly, making up and down, expulsion pressure, the emitted dose of gas-pressurized also are easy to synchronously, do like this, it is one qualitative that gas inclusion amount often has, as shown in Figure 4, can not cause over the indefinite form of common abacus pearl, uneven ground stabilization body 57, and cause the uniformly good ground stabilization body 22 (with reference to Fig. 5) of concavo-convex few typing.Therefore, can cause and do not waste and add solid reliably.

In other words, adjust discharge pressure, just can freely adjust the expulsion pressure up and down and the emitted dose of gas-pressurized by the valve of regulating on the air compressor.
Make the hardening of ground agent device for casting that possesses above-mentioned formation drop to the stage of prescribed depth, Yi Bian make it spray various jet flow things, Yi Bian its revolution is risen.Therefore, upper nozzle 13 be the high-pressure water of gas-pressurized institute inclusion around spraying, and at underground disturbance grogs, causing the people is the space, follows, and the super-pressure hardener that sprays together from lower nozzle 14 and gas-pressurized just fills up this space part.
Do like this, the hardening of ground agent just ejects from lower nozzle 14 as the high speed object, Yi Bian destroy, disturb and mix object soil, mixes soil Yi Bian sneak into to disturb.Adopt this method, with only spraying the hardening of ground agent different, can determine that the ground hardener sneaks into scope with pressure, the hardening of ground agent is not only permeated, even is the state of sneaking into, so the ground consolidation degree is strengthened and forms the strong solid that adds.
The present invention is made of above-mentioned part, has effect described below.
Up and down around the as easy as rolling off a log adjustment of expulsion pressure of the gas-pressurized of nozzle ejection, even existing problem also all solves in the excellent construction method of foregoing tradition, and have omnipotent performance and deal with the situation of all from now on, from this point, the present invention can be described as epoch-making invention.
Different with conventional method, because expulsion pressure of gas-pressurized is adjusted easily about this, therefore can make expulsion pressure, the emitted dose mediation of gas-pressurized up and down, gas inclusion amount often keeps certain about making, thereby formation is finalized the design evenly and the ground stabilization body (with reference to Fig. 5) of high-quality.Therefore, air-lift unit effect so far further increases, and the displacement efficiency of mud and hardener is improved, and can guarantee the reliability of constructing and high efficiency perfusion, and the differential pressure problem that in the past was considered to the gas-pressurized up and down of trouble, difficulty all is readily solved.
