Abstract
The utility model relates to a pile foundation construction especially relates to the pile foundation construction method on the hard soil layer. A make things convenient for drilling equipment in advance of engineering construction, it includes: one section circular steel tube, its diameter less than or equal to design stake footpath, a square steel sheet, its closing cap weld on the circular steel tube top, a H shaped steel, it with its the side welded fastening on square board, a round steel board, its welding closing cap is fixed in the circular steel tube bottom, a steel pointed cone, it is formed by four triangle -shaped steel sheet welding to weld under the round steel steel sheet with the bottom, a cone, it is in by the welding four fan -shaped steel sheets between the triangle -shaped board of steel pointed cone constitute. The utility model discloses can reduce and draw the hole degree of difficulty, shorten the engineering time, protection construction machinery guarantees construction quality.
Description
Technical field
The utility model relates to foundation pit construction, particularly relates to the foundation ditch construction method in rock foundation.
Background technology
The construction such as current CFG stake, sand drain stake, plastic draining board adopts a fixed method of carrying vibration press-in, and when running into the harder region of riprap layer, Tang Geng, layer of sand, fill stratum, pile body is difficult to penetrate and maybe cannot penetrates hard soil layer, affects normal construction.When forcing when using stake machine itself to penetrate hard soil layer, easily causing pile body generation skew or stake machine to be damaged, affecting workmanship.If adopt auger power traction hole; can construction costs be increased, spiral drilling machine construction and maintenance cost high, translational speed is slow.
Summary of the invention
The utility model is intended to the defect overcoming prior art, provides a kind of prebored hole device facilitating engineering construction.The utility model is applicable to the engineering constructions such as CFG stake, sand drain stake, plastic draining board and runs into the hardpan such as jackstone, the ridge, the pool, cannot normal construction time prebored hole, ensure penetration rate.
A kind of prebored hole device facilitating engineering construction of the utility model, it comprises:
One section of round steel pipe, its diameter is less than or equal to design stake footpath;
A square plate, its capping is welded on round steel pipe top;
A H profile steel, it is weldingly fixed on square plate with its side;
A round plate, its welding capping is fixed on round steel pipe bottom;
A steel pointed cone, it is welded by four triangular steel plate, and with bottom welding under round plate;
A cone, it is made up of four fan-shaped steel plates between the triangular steel plate being welded on described steel pointed cone.
Clamp H profile steel with spile pile machine during the utility model construction to carry out drawing hole, the model of spile pile machine is determined according to drawing hole difficulty, adopts high-power spile pile machine when soil layer is comparatively firmly thicker.The utility model can be customized at the construction field (site), can utilize steel pipe, steel that some are discarded, and cost is low, can reuse, make simple, this device can reduce and draw hole difficulty, and shorten the engineering time, protection construction machinery, ensures construction quality.
Accompanying drawing explanation
Fig. 1 is the utility model scheme of installation.
Detailed description of the invention
As shown in Figure 1, comprise the one block of circular steel plate 2 in bottom, link a steel pointed cone 4 below circular steel plate 2, steel pointed cone 4 is welded to form by four pieces of triangular steel plate; Steel pointed cone 4 surrounding connects four block plates 3 and forms cone, a round steel pipe 1 is linked above circular steel plate 2, steel pipe 1 length is determined according to the hard soil thickness in scene, steel pipe top links one piece of square plate 5, square plate 5 top links one piece of H profile steel 6, during construction, spile pile machine is clamped H profile steel 6 and is pressed in soil layer and draws hole, and spile pile type is selected according to drawing hole difficulty.
Method of attachment between above-mentioned all parts is welding.
