Abstract
The present invention relates to a high-property cement earth pile construction method which is characterized in that the method comprises the following steps: 1) forming a hole or a groove by a hole forming device; 2) blending mud, solidifying agents and external mixing agents outside the hole to form high-property cement earth slurry; 3) filling or pressing the high-property cement earth slurry into the hole or the groove by a slurry filling pump. The present invention thoroughly changes a traditional cement earth forming technology, namely changing the mode of mixing cement earth at home position in an underground hole to form piles into the mode of mixing mud and solidifying agents outside the hole to form piles. A high-property cement earth pile formed by the method has higher intensity, better performance and lower cost than a traditional cement earth pile. The present invention is suitable for the underground engineering in the fields of civil engineering and construction.
Description
Technical field
The present invention relates to the underground construction of building and building field, specifically a kind of job practices of high-performance cement soil stake.
Background technology
In building and building engineering field, cement earth pile has powder spray piling, slurry spray stake and high-pressure rotary jet grouting pile at present, and there is the following problem in these cement earth piles:
1, powder spray piling, slurry spray stake all are cement mixing methods, and its moulding process is that original position stirs in underground stake hole, and limit spraying cement or cement paste limit promote drilling rod, and jet velocity and hoisting velocity are difficult to coupling, thereby easily cause the common quality defect of " multi-layer steamed bread ".
2, since when powder spray piling and slurry spray pile driving construction the cement amount of the cement-soil in the drill pipe diameter seldom also be difficult to stir, promptly pile body is outer soft in hard, is commonly called as in the industry to be " egg core ", this common quality defect also is masty.
3, owing to above reason, quality problems often appear in a lot of powder spray pilings and a slurry spray stake engineering, some area even forbidden adopting this two kinds of stake types.
4, high-pressure rotary-spray cement earth pile, be by water under high pressure, gas, slurry, can pass through single tube, dual pipe, triple pipe, rely on the high-pressure rotary-spray jet in underground hole, to carry out the original position pile, the pile body diameter can differ bigger according to soil property situation difference, and also occurs dried layer cake phenomenon and the expanded diameter quality problems less than intended diameter easily.
Summary of the invention
The present invention seeks to propose a kind of job practices of high-performance cement soil stake, make it can solve " egg core " and the common quality defect of " multi-layer steamed bread " that the conventional soil cement stake produces in order to solve the problem that the above-mentioned background technology exists.
For achieving the above object, the present invention adopts following technical scheme:
1. the job practices of a high-performance cement soil stake is characterized in that this method adopts following steps:
1) adopts pore-forming equipment pore-forming or grooving;
2) outside the hole, utilize mud and curing compound and additive to stir into the high-performance cement soil paste;
3) with grouting pump above-mentioned high-performance cement soil paste is injected or be pressed in above-mentioned hole or the groove.
The present invention has thoroughly changed the moulding process of conventional soil cement, is promptly changed into by original position stirring concrete earth pile in the underground hole and utilizes mud and curing compound to stir outside the hole, and it has following advantage:
1, the moulding process of cement-soil is stirred to change into outside the hole by original position in the underground hole and stirs, and soil cement slurry stirs, and can make the high-performance cement soil that satisfies different resistance to compressions, anti-permeability performance according to different needs.
2, can utilize discarded slurry, turn waste into wealth, reduce pollution environment.
3, good with the high-performance cement soil stake strength ratio of this method construction traditional cement earth pile height, anti-permeability performance, cost is low, and it is applicable to the underground construction of building and building field.
Description of drawings
Fig. 1 is the schematic diagram of high-performance cement soil stake.
In the drawings, 1-hole, the stake of 2-high-performance cement soil, 3-core, 4-soil layer.
The specific embodiment
The present invention adopts following steps:
1, adopts rig or long spiral equipment or revolve and dig equipment pore-forming or grooving;
2, utilizing mud and cement outside the hole is that curing compound and additive stir into the high-performance cement soil paste;
3, with grouting pump above-mentioned high-performance cement soil paste is injected or be pressed in above-mentioned hole or the groove;
4, in above-mentioned high-performance cement soil stake, insert steel work or concrete structure core.
Claims (3)
1. the job practices of a high-performance cement soil stake is characterized in that this method is made up of following steps:
1) adopts long spiral equipment or revolve and dig equipment pore-forming or grooving;
2) outside the hole, utilize mud and curing compound and additive to stir into the high-performance cement soil paste;
3) with grouting pump above-mentioned high-performance cement soil paste is injected or be pressed in above-mentioned hole or the groove.
2. according to the job practices of the described high-performance cement soil stake of claim 1, it is characterized in that described curing compound is that cement is curing compound.
3. according to the job practices of claim 1 or 2 described high-performance cement soil stakes, it is characterized in that in above-mentioned steps 3) then in the high-performance cement soil stake, insert core.
