Abstract
The invention belongs to bridge construction technical fields, are related to a kind of water mill brill construction method of the artificial digging pile for bridge pile foundation engineering.This approach includes the following steps：1）After determining pile foundation borehole position and diameter, it is carried out continuously bore operation along the circumferential edges of pile foundation hole with water mill brill, the depth each to drill is determined by drilling pipe length, and each drilling is tangent successively or intersects, and core is transported after drilling；2）Using the broken removal pile foundation hole central part of pneumatic pick, broken rock slag is transported, the borehole operation of one section of depth is completed；3）Step 1 is repeated several times）To step 2）, the borehole operation of next section of depth is completed, until reaching the projected depth of pile foundation hole.The method boring procedure operation of the present invention flexibly, easy maintenance, construction safety, pollution it is small, while shaking and noise is small, in the region of unsuitable explosion, construction has prodigious advantage.
Description
Technical field
The invention belongs to bridge construction technical field, it is related to a kind of artificial digging pile for bridge pile foundation engineering
Water mill bores construction method.
Background technology
At present in Bridges in Mountainous Areas pile foundation construction, manually digging hole enters behind rock stratum the side for generally using emulsion explosion
Formula, but there are larger security risks for this method, and when close to resident house, the shock wave that explosion generates is easy to cause house
Harm, it is unfavorable to the personal safety of resident, and it is serious to disturb residents.It is not easy to control for the aperture in hole simultaneously in explosion, it causes
Aperture is excessive, the serious phenomenon of the super side of concrete.
Invention content
That the technical problem to be solved by the invention is to provide a kind of working securities is good, vibrations and noise are small, dust pollution
Small, the construction high artificial digging pile of accurate size water mill bores construction method.
The water mill of the artificial digging pile of the present invention bores construction method：
Hoisting bracket is set on the aperture ground of pile foundation hole and lifting appliance is installed；
1）After determining pile foundation borehole position and diameter, it is carried out continuously bore operation along the circumferential edges of pile foundation hole 1 with water mill brill, often
The depth of a drilling is determined that each drilling is tangent successively or intersects, and core is transported after drilling by drilling pipe length；
2）Using the broken removal pile foundation hole central part of pneumatic pick, broken rock slag is transported, the borehole for completing one section of depth is made
Industry；
3）Step 1 is repeated several times）To step 2）, the borehole operation of next section of depth is completed, until the design for reaching pile foundation hole is deep
Degree.
Further, in above-mentioned steps, derrick 2 is set in the well head of pile foundation hole, and lifting appliance 3 is installed, passes through lifting
Equipment handling drilling pipe, core and rock slag.
The drilling pipe length is 50-70cm, a diameter of 15-18cm.Preferred drilling pipe length is 60cm, a diameter of 16cm.
The present invention method boring procedure operation flexibly, easy maintenance, construction safety, pollution it is small, while shake and noise
It is small, there is prodigious advantage in the region construction of unsuitable explosion.
Description of the drawings
Fig. 1 is the Construction State schematic diagram of the method for the present invention；
Fig. 2 is pile foundation hole bottom hole distribution schematic diagram.
Specific implementation mode
The method of the present invention is described further with reference to embodiment.
Embodiment：
The work progress of the embodiment of the present invention（Referring to Fig. 1）：
1）After determining pile foundation borehole position and diameter, derrick is set in the well head of pile foundation hole, and lifting appliance is installed, is bored with water mill
Circumferential edges along pile foundation hole are carried out continuously bore operation, and according to the specification of drilling pipe, the depth each to drill is 60cm, a diameter of
16cm, each drilling is tangent successively or intersects（Such as Fig. 2）, fortune goes out core by lifting appliance after drilling；
2）Using the broken removal pile foundation hole central part of pneumatic pick, broken rock slag is transported by lifting appliance, completes one section
The borehole operation of depth；
3）Step 1 is repeated several times）To step 2）, the borehole operation of next section of depth is completed, until the design for reaching pile foundation hole is deep
Degree.
Above-mentioned work progress is not necessarily to bursting work, will not cause to damage to neighbouring building construction, ensure that construction safety,
Also reduce the influence to environment.
