Summary of the invention

Block the problem of stake easily in order to solve repeated use of existing piling supplementary structure and removal process simultaneously, the utility model provides a kind of combined type piling to set upright structure.The combination of structure through simple member and parts set upright in this combined type piling, not only can reuse, and adapt to the piling work of multiple stake footpath and pile spacing, effectively avoided simultaneously the generation of card stake phenomenon in the removal process after piling is finished, reached raising pile works compliance and operability, and the purpose that reduces the integrated cost of pile works.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of combined type piling is set upright structure and is made up of the braced structures that is no less than between three pilot sleeves and the pilot sleeve, it is characterized in that the braced structures between adjacent two pilot sleeves is to removably connect as being connected between a rigid unitary and the pilot sleeve, can be that flange connects, also can be other forms of mechanical connection; Braced structures determines that according to the piling bar design pitch it connects length and form of structure.Be no less than the adjustable stopping means in three roads along even setting of barrel in the pilot sleeve.Pilot sleeve is made up of barrel, horn mouth and stopping means, it is characterized in that the per pass stopping means in the barrel comprises that quantity is no less than two cover stopping means; Every cover stopping means is regulated bolts by limited block and two and is formed, and two are regulated the screwed hole that bolt passes respectively on the interior limited block of circular hole that being slightly larger than on barrel and the barrel stiffener regulate the diameter of bolt and barrel and are connected.By screwing the adjusting bolt, can realize the advance and retreat of limited block with respect to barrel, make to be no less than the common restricted quarter of holding piling bar of forming of three road stopping means.Limited block can be according to pilot sleeve diameter and piling bar diameter commonly used according to its thickness seriation, and by changing the limited block of different-thickness, same guided diameter sleeve can adapt to the piling work of different-diameter piling bar.According to piling bar stake footpath, adjust the position of limited block in pilot sleeve of all stopping means, form the restricted quarter that is slightly larger than the piling bar diameter, thereby realize that the piling bar pitching pile goes into the accurate location of mud, also guaranteed that piling bar squeezes into verticality in the process simultaneously.After all piling bar piling is finished, before structure is set upright in lifting recovery piling, by screwing the adjusting bolt, limited block is retracted to be adjacent to the pilot sleeve inwall, gap between limited block and the piling bar increases to maximum, avoids reclaiming that configuration process is set upright in piling because stuck phenomenon between piling bar that the piling error of perpendicularity causes and the pilot sleeve.

The beneficial effects of the utility model are: 1) by the combination of varying number pilot sleeve, change the braced structures of different length, can adapt to the piling bar of varying number and the pile works project of piles with different distance; 2) combination of limited block and the pilot sleeve by seriation makes the pilot sleeve of same dimensions adapt to the piling work of different-diameter piling bar, having improved the versatility that structure is set upright in piling; 3) regulate the position of limited block in pilot sleeve by regulating bolt, under the prerequisite that guarantees piling positioning accuracy and verticality, solved piling and set upright the card stake problem that structure often runs in the lifting removal process.
