Abstract

The invention relates to a building construction method, in particular to a high-efficiency combined construction method suitable for drilling a rock stratum into a pile by utilizing an all casing drill. The method comprises the following steps: 1, positioning a pile position, and placing the all casing drill to a right position; 2, pressing in a steel sleeve, and taking soil to the rock surface in the sleeve by percussion and grabbing or rotary drilling; 3, lifting a down-hole hammer, and mounting the down-hole hammer to the steel sleeve; 4, starting the down-hole hammer to drill the rock to a projected depth, and clearing the hole; 5, mounting a reinforcement cage and pouring concrete; and 6, pouring concrete, and simultaneously pulling up the steel sleeve until the steel sleeve is completely pulled out. The method has the advantages of simple and practical operation, small damage to the ground, no collapse during construction, good piling quality, good water proof effect, high piling efficiency, low construction cost, no pollution during construction and efficient and quick rock drilling.

Description

The method that all casing drill cutter is got the rock pile
Technical field
The present invention relates to a kind of construction techniques, particularly a kind of all casing drill combination constructing method thereof that is adapted at rock stratum high efficiency boring and pile.
Background technology
Worker's method of all casing drill is a most frequently used piling method during present city secondary is built, its advantage is that excavation, construction area are little, influences little, pollution-free to the underground soil body, construction surrounding enviroment, when removing obstacles, can irritate pile driving construction, avoid the excavation that repeats of a plurality of operations, and since the retaining wall effect of steel sleeve, the hole quality height, the hole can not collapse, the verticality height, the reaming size is little, the efficiency of construction height.Have residual stake because the depth of building of city secondary construction is higher and deep layer is underground, so this employing worker method will inevitably run into competent bed or residual stake.Worker's method of all casing drill is applicable to soil layer or incompetent bed very much, go into then difficulty of hard rock, meet greater than half boulder intractability of stake footpath big, though in practical operation, can adopt supporting facility to cut rock, but therefore efficiency of construction can reduce greatly, and operation is also comparatively complicated.
Downhole hammer rock drilling machine has used comparatively ripe abroad, its advantage is the construction that penetrates that is specially adapted to hard rock stratum such as lithosphere, boulder bed, but play whole machine cost height, the combined no outer tube of crane, its retaining wall effect is undesirable, the hole that still can collapse, and construction pollution is big, being used for getting the above soil of lithosphere has the sense of wasting one's talent on a petty job, and can increase construction cost.
Technical scheme
Technical problem to be solved by this invention provides the method that a kind of all casing drill cutter is got the hard rock pile, operation is simple for it, do not collapse that hole, pile quality are good in, the construction little to the ground breakage, good water-proof effect, pile efficient height, cost is low, construction is pollution-free, and can cut a hole the brill hard rock efficiently, fast.
Realize that the technical scheme that the object of the invention adopted is:
Processing step is as follows
1. fixed stake position, all casing drill is in place;
2. be pressed into steel sleeve, take soil to rock face towards grabbing or revolving in the pipe;
3. hang in down-the-hole hammer assembly and be installed on the steel sleeve;
4. start downhole hammer rock to projected depth, clear hole;
5. reinforcing cage is installed and is poured into concrete;
6. pour into concrete on one side, pull out steel sleeve on one side simultaneously, until all extracting steel sleeve.
In aforesaid operations of the present invention, down-the-hole hammer assembly overlaps all casing drills and is used with many, and rock drilling directly lifts on the other steel sleeve in scene with pedrail crane during to projected depth; The steel sleeve upper end is equipped with Connection Card, and the mesopore of Connection Card is to the sleeve pipe radial location of down-the-hole hammer assembly.
When the aperture behind the downhole hammer rock does not meet design requirement, should adopt jump bit or Spiral digging machine to add and be pressed into sleeve pipe the petrosal foramen deburring, repair the hole to meeting design requirement to extremely.
The invention has the beneficial effects as follows: all casing drill and the unification of downhole hammer rock drilling machine two machines, to make the most of the advantage separately, all casing drill performance steel sleeve is pressed into and retaining wall, fetch earth fast to rock face, down-the-hole hammer assembly is platform with all casing drill with the sleeve pipe that is pressed into, and carries out quick rock drill and gets, and the hole does not therefore collapse in construction, pile quality is good, good water-proof effect, pile efficient height, cost is low, it is pollution-free to construct, and has again simultaneously to cut a hole efficiently, apace to bore hard rock.
Description of drawings
Fig. 1 is a process flow diagram of the present invention;
Fig. 2 is an equipment overall schematic of the present invention.
Among the figure: Connection Card 1, unit head 2, muck removal pipe 3, electrical control cubicles 4, pneumatics unit 5, rock face 6, down-the-hole hammer assembly 7, steel sleeve 8.
The specific embodiment
Referring to each figure, processing step of the present invention is as follows:
1. fixed stake position, all casing drill is in place;
2. be pressed into steel sleeve 8, adopt in the pipe to dash to grab or revolve to take soil to rock face;
3. on the Connection Card 1 that hangs in down-the-hole hammer assembly 7 and be installed to, make the centring ring above the Connection Card 1 do radial location to the sleeve pipe of down-the-hole hammer assembly, Connection Card 1 following collar is enclosed within steel sleeve 8 upper end bolt;
4. start downhole hammer rock to projected depth, measure hole depth and aperture, when the aperture behind the downhole hammer rock does not meet design requirement, should adopt jump bit or Spiral digging machine to add and be pressed into sleeve pipe, repair the hole to meeting design requirement to extremely clear hole to the petrosal foramen deburring; Simultaneously down-the-hole being hammered into shape assembly directly lifts on the other steel sleeve in scene with pedrail crane and carries out same operation;
5. reinforcing cage is installed and is poured into concrete;
6. pour into concrete on one side, pull out steel sleeve on one side simultaneously, until all extracting steel sleeve.

Claims (3)

1. an all casing drill is cut a hole the method for getting the rock pile, it is characterized in that processing step is as follows:
1. fixed stake position, all casing drill is in place;
2. be pressed into steel sleeve, take soil to rock face towards grabbing or revolving in the pipe;
