Abstract
The invention relates to a construction method of long auger drilling concrete-grouted back-plugged profile steel piles. The method mainly comprises the following steps: drilling holes by using a long auger drilling machine and taking soil; drilling to the designed depth, and grouting concrete; manufacturing a back-plugged profile steel component, processing a circular hole with the diameter of 5cm at a position which is 5cm away from the top of an I-bar, manufacturing a T-shaped plug by using a steel bar with the diameter of 14mm, connecting the profile steel with a vibration connector by using the T-shaped plug, and coiling the flange of the lower part of the profile steel inwards by 60 degrees; connecting a profile steel pile with the vibration connector, lifting and centering; sinking by utilizing the dead weight of the profile steel pile in the early stage, and after sinking to a certain depth, starting a spring vibration hammer until the profile steel pile sinks to the designed position under the action of vibration, wherein in the construction process, special persons are designated to control the verticality by using two theodolites and control the top height by using a balance level; and dismantling the connector to obtain the pile. By utilizing the construction method, the quality problem in foundation ditch slope-protection support pile construction in a narrow space is solved, and the problems that the back compressed steel bar cage of small-diameter pile foundations can not sink to the designed position and voids can be easily formed are also solved. The construction method provided by the invention has the advantages of less working procedures and small occupied construction site.
Description
Affiliated technical field
The present invention relates to a kind of long auger cast-in-place concrete pile pile foundation construction, be applicable to that especially the construction plant is narrow and small, the stake footpath is less than the pattern foundation pit supporting structure slope protection pile of 400mm.
Background technology
At present, generally insert the job practices of reinforcing cage behind the long auger guncreting of Cai Yonging, patent of invention " inserting reinforcing cage construction technology and reinforcing cage gatherer behind the long auger pumping concrete pile " (application number 200310101954.3), for the pile foundation of diameter less than 400mm, reinforcing cage rigidity is little, the reinforcing cage resistance capacity to deformation is poor, adopt special-purpose Pile feeder to construct, Pile feeder is isometric with reinforcing cage basically, again Pile feeder is extracted after reinforcing cage delivered to the precalculated position, increased the resistance in the reinforcing cage sinking process on the one hand, reinforcing cage is heavy to be established less than design attitude, and pile body easily forms the hole gap in the pile pulling process on the other hand, influences pile quality, the length consuming time of constructing, efficiency of construction is low.The reinforcing bar blanking, reinforcing cage is made needs large stretch of place, and limited construction plant is difficult for carrying out in the city.
Summary of the invention
For slotting reinforcing cage job practices reinforcing cage in the pile foundation construction of paxilla footpath after overcoming existing long auger guncreting can not sink to design attitude, easily form the hole gap, construction efficiency is low, shortcomings such as occupied ground is big, the present invention proposes the job practices that the shaped steel stake is inserted in a kind of back, and this method working procedure is simple, easy construction, pile quality is good, environmental protection, mud-less pollution.
The present invention solves the technical scheme that its technical disadvantages adopts:
Shaped steel stake vibration linkage is inserted in a kind of back, comprise with spring vibration hammer flange connecting dish, steel bushing, be connected shaped steel, branch sleeve, it is characterized in that: described steel bushing one end and flange welding, the other end be connected shaped steel welding, described connection shaped steel stretches in steel bushing and the branch sleeve and welding, opens the rectangular card pin-and-hole on the described branch sleeve.
The shaped steel pile construction method is inserted in a kind of back, and the main construction equipment that this job practices adopts is long-spiral drilling machine, crane, vibrating hammer, vibration linkage, shaped steel stake, transit, level gauge.
Main construction sequence:
1, stake position unwrapping wire is accurately made the pile foundation center;
2, make the back and insert Steel section member, select i iron for use, the size of i iron is determined according to the size requirements of force request, stake bore dia by the designer.Apart from 5cm place, i iron top, process a diameter 5cm circular hole, be used for lifting as pin hole.With diameter is the reinforcement fabrication T-shaped latch of 14mm, utilizes T-shaped latch that shaped steel and vibration linkage are linked together.The heating back processing of the edge of a wing, shaped steel bottom is spent to curls inward 60, and it is difficult for influencing pile quality with stake bore edges generation scratch.
3, adopt the full screw earth auger boring extracting soil;
4, drilling to completion, guncreting to design specifications requires height, and the super certain altitude of irritating;
5, the shaped steel stake is connected lifting, centering with the vibration linkage;
6, the initial stage sinks by shaped steel stake deadweight, after sinking to certain depth, start vibrating hammer, vibration-sunk is to design attitude, slowly sink to concrete to stake top mark height at shaped steel, electromagnetic shaker vibrates 2～3 minutes again, to guarantee concrete compactness, arrange the special messenger to control its verticality centering position in the work progress, control its top mark height with level gauge with two transits;
7, remove linkage, pile.
Beneficial effect of the present invention: solved small space foundation ditch bank protection soldier pile construction difficult problem, press reinforcing cage can not sink to design attitude after having solved paxilla footpath pile foundation, easily form quality problems such as hole, concrete leakiness, working procedure is simple, it is little to take the construction plant, the work efficiency height.
