Abstract
A pile forming machine tool for a drilling concrete pouring hollow pile comprises an inner steel die, a drilling stem and a drilling tool. The inner steel die includes two sections of hollow cylinders, wherein the two sections of the cylinders are connected, the diameters of the upper cylinder and the lower cylinder are different, the upper cylinder is longer than the lower cylinder, the diameter of the upper cylinder is smaller than that of the lower cylinder, a reinforcing steel bar cage is disposed on the outer side of the upper cylinder, and the bottom of the main reinforcing steel bar of the reinforced steel bar cage penetrates the end face of the lower cylinder and is inserted into the reinforcing steel bar protecting tube in the lower cylinder. The drilling stem is connected with a central tube through a flange connector. The drilling stem and the central tube are mounted in the inner steel die. A drill bit is fixedly mounted at the lower end of the central tube. A reamer bit is movably mounted at the lower end of the central tube through a pin. The drill bit and reamer bit are both disposed in the lower cylinder of the inner steel die. The top end of the upper cylinder is connected with an inner die gland provided with a water suction pipe. The pile forming machine tool has the advantages that the drilling concrete pouring hollow pile can be formed as long as drilling can be performed, the difficulty caused by complex engineering geology and hydrogeological conditions is avoided, pile forming cycle can be shortened by half, and construction cost is lowered greatly.
Description
Technical field
The present invention relates to building engineering equipment, especially one waters concrete hollow pile pile facility with brill.
Background technology
Conventional bored pile boring, than very fast when boring soil, and just must change punching into once enter middle weathering hard rock or meeting Rolling Stone erratic block, punching is then very slow, if expand the end with mechanical hole reaming drill bit, that is just more difficult, nowadays oneself little use.Owing to there being concrete guard wall to protect in hand excavated pile, the end can be expanded by the quick-fried rock of Bian, the proportional raising of bearing capacity of pile tip can be made.If the design length of but meeting rich groundwater or stake is long, hole digging pile does not just allow to have constructed, if pile foundation can not be located predetermined level, so bearing capacity of pile tip just can not meet designing requirement and becomes dangerous stake.
Summary of the invention
Object of the present invention be just to provide a kind of applied widely, the pile cycle is short, construction cost is low, pile quality is good waters concrete hollow pile pile facility with brill.
Of the present inventionly water concrete hollow pile pile facility with brill, comprise motor, interior punching block, drilling rod, reinforcing cage, drilling tool, motor output shaft is connected with drilling rod, it is characterized in that, interior punching block be two sections of disjunctors, up and down diameter not etc., the cylinder of hollow, the length of epimere is greater than hypomere, and the diameter of epimere is less than hypomere, the lateral surface of interior punching block epimere is provided with reinforcing cage, to be inserted in hypomere cylinder in Hu Zhu pipe bottom reinforcing cage Zhu Zhu through the cylindrical end face of hypomere; Drilling rod is connected with central tube by flange socket, drilling rod, central tube are contained in interior punching block, drill bit is fixedly mounted on central tube lower end, reaming bit is movably arranged on central tube lower end by pin, the upper end of reaming bit contacts with the telescopic piston be enclosed within central tube, the stage clip one end be enclosed within central tube is connected with telescopic piston, and the other end is connected with flange socket, and drill bit and reaming bit are all located in interior punching block hypomere cylinder; The cylindrical top of epimere is connected with internal mold gland, and internal mold gland installs suction water pipe, and well head hopper is enclosed within the reinforcing cage of interior punching block lateral surface.
Of the present inventionly water concrete hollow pile pile facility with brill, during work, driven by motor drilling rod and central tube rotate, drill bit, the reaming bit of central tube lower end creep at work plane, first while soil layer boring, water concrete with brill, brill limit, limit is watered concrete and is followed the top board to basement rock just to constitute the hollow pile of certain wall thickness, and reaming bit equals wall thickness to the amount of external extension, during lifting drilling tool, reaming bit blade draws in automatically according to deadweight, can pass through modular space in steel smoothly.Suction water pipe on internal mold gland is used for drawing water, and keeping not only can direct circulation but also pumpable is inhaled or the dual-purpose water route of reacting cycle lifted by pump, and drill bit cuts soil, hydraulic slag discharging, is inside molded into the soil body, and concrete sinks from the cast of well head hopper, closely knit with drilling tool shake.
Of the present inventionly water concrete hollow pile pile facility with brill, contrast conventional bored pile and have the following advantages:
As long as 1 bores to enter, just can water concrete with brill becomes hollow pile, thus makes complicated engineering geology and hydrogeological conditions not become difficult matter or technical bottleneck;
2, because hollow pile wall water proof is arranged at top, can manually go into the well during embedding rock with the embedding rock of method of perforating explosion, it is faster than punching speed, and the degree of depth of embedding rock can easily meet design requirement, sediment at the bottom of hole can also definitely reset, and this is that any bored pile is not accomplished;
3, hollow pile manually can be gone into the well after removing internal mold and directly be checked on the quality, comprise defect to take pictures and concrete face bounce-back test etc., find that concrete defectiveness can be repaired in time, and the embedding rock of embedding rock upper back king pile and bottom or expanded bore pile, can connect with concrete perfusion is wet, therefore pile foundation quality can reach all-round excellent;
4, implement space for Shi Hanzhang bundle provides, can make that pile is conjuncted saves cushion cap;
5, the pile cycle can shorten half, is constructed into instinct and reduces by three one-tenth, and cement consumption 20% economized by non-underwater concreting.
