Description
[technical field]
The utility model relates to a kind of Foundation Design bored pile that is applied in normal boring, and the brill of finishing ream operation quickly and accurately in the soil layer position that is fit to reaming expands one-shot forming apparatus.
[background technology]
Drilling hole bored concrete pile technology is widely used in the Foundation Design field at present.Along with being on the increase of highrise building, to the also constantly increase of requirement for bearing capacity of pile foundation.The supporting capacity of bored pile derives from the end resistance of stake end soil and the frictional resistance of stake side soil, is not fully utilized but the stake side has the soil layer of higher-end resistance.Continuous development along with science and technology, begin to have adopted in some construction works support disk pile (DX stake) technology from the nineties, its principle is exactly effectively to utilize the stake side soil layer with higher-end resistance, its bearing capacity can improve more than 50% with comparing with the condition bored pile, reduce construction costs simultaneously, but its weak point is: 1, must cooperate by crane when squeezed operation, its construction safety assurance property is poor; 2, each dish need be repeatedly squeezed, and efficiency of construction is low, particularly artificial rotational angle, and the human factor influence is big, and reliability is low; When 3, squeezed the expansion dish up and down the soil body produce undergauge and influence pile quality, as must bore then efficiency of construction reduction again for eliminating undergauge with rig; Sediment reached several meters more than at the bottom of hole wall collapse caused the hole when 4, squeezed, and the clear hole time is long, particularly often sank at the bottom of the hole with the block soil body, then must bore sediment at the bottom of the ability cleaning hole again with rig, and efficiency of construction is low; 5, owing to be that the two procedures cooperation is finished, need several hrs just can finish squeezed operation under the normal condition after boring is finished, as occurring above-mentioned 3,4 situation again, the hole wall time that suspends often is tens hours even tens hours, and the pile quality reliability is low; 6, when when squeezed than hardpan, branch tray machine can't get out; 7, when when viscous soil horizon is squeezed, because of each expansion dish needs repeatedly squeezed, withdrawal, the anglec of rotation, hole side soil moves just as kneading dough to squeeze back and forth, can't guarantee the physical dimension of design; 8, when squeezed, when the block with certain degree of hardness is stuck between branch tray machine and the hole wall, often cause branch tray machine to put forward; 9, because of material and mechanicalness the subject of knowledge and the object of knowledge limit, it is stressed big to add when squeezed bow pressing arm and pivot pin, and bow pressing arm or pivot pin often rupture, and cause branch tray machine to put forward; Hydraulic oil pipe generation explosion when 10, squeezed, bow pressing arm can't normally be regained, and causes branch tray machine to put forward.
[summary of the invention]
The purpose of this utility model is to solve the prior art above shortcomings, provides a kind of brill to expand one-shot forming apparatus, so that in common bored pile boring, can finish ream operation in the soil layer position that is fit to reaming quickly and accurately.
The brill that the utility model provides expands one-shot forming apparatus, comprise drill bit, shell, drill bit is fixed on the bottom of central tube, the top of central tube is fixed on the shell lower end by the following fixed support and the mounting flange of shell lower end, the fixed support that its middle part has circular hole is installed in the upper end of shell, the stayed mast that is used for reaming passes from the circular hole on the fixed support, lower end near stayed mast is fixed with a travel(l)ing rest, the lower end of two operator bars is hinged on the travel(l)ing rest respectively by following cutter shaft, the upper end of two operator bars is hinged with the lower end of two auxiliary knife bars respectively by middle cutter shaft, the upper end of two auxiliary knife bars is hinged on the fixed support respectively by last cutter shaft, on the stayed mast between fixed support and the travel(l)ing rest, be set with compression spring, the anti-silt particle extension sleeve of the outer suit of compression spring has the reaming groove with operator bar and auxiliary knife bar correspondence position on the shell two side.
This bores and expands one-shot forming apparatus, also a drilling rod pipe can be installed above fixed support, the lower end and the fixed support of drilling rod pipe are fixed, the upper end is for being used for the drilling rod flange of jointed rod, the inside of drilling rod pipe is provided with the dividing plate that its middle part has circular hole, is set with compression spring on the stayed mast between dividing plate and the fixed support.
Its operating principle is: when stayed mast unclamps, under the effect of compression spring, operator bar and auxiliary knife bar are in rounding state; When the needs reaming, apply pulling force by the chest expander gear train assembly to stayed mast, in the time of the drilling rod rotation, operator bar and auxiliary knife bar constantly expand outwardly and carry out ream operation.For avoiding occurring the dead point, the central point of cutter shaft is positioned at the central point line outside of cutter shaft and following cutter shaft in making as far as possible.
Advantage of the present utility model and good effect:
Principle of the present utility model is based on equally and makes full use of the stake side soil layer with higher-end resistance, and at utmost for pile foundation provides bearing capacity, above-mentioned all weak points that support disk pile is existed all are resolved.Have following advantage: 1, boring the expansion equipment integrating does not need crane to cooperate, and its construction safety guarantees property height, and the construction equipment occupied ground is few; 2, each reaming is by the rotation one-shot forming, and the reaming regular shape can guarantee the physical dimension of reaming, the efficiency of construction height, and the human factor influence is little, the reliability height; 3, during reaming up and down the soil body can not produce undergauge and influence pile quality, do not need to bore again the efficiency of construction height with rig; 4, the sediment of reaming generation is in time drained with mud circulation, waits to hole to projected depth, and sediment can be removed the efficiency of construction height simultaneously at the bottom of the hole; 5, owing to be that the boring reaming is finished simultaneously, the hole wall time that suspends is lacked pile quality reliability height; 6, when when hard or viscous soil horizon need reaming, the same simple and fast of ream operation, and can guarantee the physical dimension of design; 7, because Counterboring apparatus is in rounding state under the pressure of stage clip, as long as lay down the pulling force of stayed mast, Counterboring apparatus is just got back to rounding state, so under any circumstance drilling and expanding apparatus can both mention out from the hole.
