Description
Technical field
The present invention relates to a kind of filling pile constructions, more particularly to the long casing construction method of bored concrete pile.
Background technique
During filling pile construction, shield-tube embedment or the verticality to bored concrete pile is set, at pile integrality and pile matter
It measures most important.It being set in long casing construction method in traditional electronic vibration hammer, the verticality that casing is set is more secure, but
To the casing of clay geology and 10 meters or more, powerful electric vibrating is needed to hammer into shape, to construction site power requirement height, and hung
Dress equipment requirement, Hoisting Security requirement are relatively high, i.e., the practicability of electric vibrating hammer and specific aim be not strong.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, the long casing construction method of bored concrete pile in a kind of argillic horizon is provided.This
Invention sets long casing using steel sheet pile machine, and highly-safe and construction efficiency is high, controls stake position and the verticality effect of bored concrete pile
Obviously.
In order to solve the above-mentioned technical problem, the present invention is implemented as follows: the long casing construction of bored concrete pile in a kind of argillic horizon
Method includes the following steps:
Step 1: smooth location: crane and steel sheet pile machine are during setting long casing, for the verticality and safety for guaranteeing casing
Construction, place is changed as needed fills out certain thickness stone and rock ballast, cooperates place mat steel plate, sets casing with steel sheet pile machine and do not sink
It falls into as standard；
Step 2, measurement are put a little: casing, which needs to measure before setting, releases three points, including bored concrete pile central point, two locating rods
Central point, two locating rods are apart from 2 meters of pile center's point or more, two locating rods and pile center's point is in 90 ° uses Large-size rebar
It is inserted into place；
Step 3, sash weight installation: sash weight is bundled in the center point of lifting casing wirerope, and binding method is not slided with sash weight is
Standard；To expose casing bottom below sash weight, to guarantee casing centering stake position；
Step 4, the control of stake position and casing degree control: casing is squeezed into before place with behind sash weight align piles position, and steel sheet pile machine is opened
Beginning suppresses casing；Stake position and verticality are verified in segmentation, such as find that one of stake position or verticality do not meet design specification requirement, again
Set casing.
The long casing construction method of bored concrete pile in the argillic horizon, it includes casing that stake position is verified in segmentation in the step 4
Before driving depth reaches the length of 1/3 casing, casing often squeezes into 0.5 meter, and the position using total station review locating rod is errorless
After, use the distance for marking graduated measuring staff measurement two locating rods of casing distance；If two distances of measurement are not identical,
Casing position does not meet design specification requirement, needs to set casing again；If two of measurement apart from identical, are continued to set shield
Length of the cylinder to depth in 1/3 casing starts, and casing often squeezes into 1.0 meters, whether meets stake using locating rod review casing position
The design specification requirement of position；
The long casing construction method of bored concrete pile in the argillic horizon, casing degree control includes: that casing is beaten in the step 4
Before entering the length that depth reaches 1/3 casing, casing often squeezes into 0.5 meter, uses 1 points of casing hang down of horizontal ruler verification
Directly spend it is errorless after, continue to set casing, if measurement the verticality for having a point it is problematic, adjustment casing is vertical again
Degree, while whether the position for verifying casing meets the requirements；If casing position deviation does not meet design specification requirement, need again
Set casing；For casing driving depth after the length of 1/3 casing, casing often squeezes into 1.0 meters, verifies casing at least using horizontal ruler
Whether the verticality of three points meets design specification requirement；If the verticality for having a point of measurement is problematic, adjustment again
The verticality of casing, while whether the position for verifying casing meets the requirements；If casing position deviation does not meet design specification and wants
It asks, needs to set casing again.
The present invention, which uses the steel sheet pile machine equipped with hydraulic vibration driver to set long casing, to be had many advantages, such as: one, hydraulic vibration driver
It can be provided in special steel sheet pile machine, the equipment such as digging machine can also be retrofitted in, flexibility is high；Two, steel sheet pile machine mobility is strong,
Service efficiency is high；Three, steel sheet pile machine does not need to can be very good to solve the problems, such as construction site shortage of electric power using electricity；Four, steel plate
It is fast that stake machine pulls up long casing speed, highly-safe；Five, stake position and the verticality effect for controlling bored concrete pile are obvious, guarantee the later period at
Pile integrity and pile quality.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is schematic diagram of the present invention；
1 is locating rod in figure, and 2 be sash weight, and 3 be horizontal ruler, and 4 be crane, and 5 be steel sheet pile machine, and 6 be measuring staff.
