However, during practice of construction, because in situ concrete pile belongs to soil compaction class pile-type, adjacent studs immersed tube set and The movement of stake machine can have a negative impact to not yet pre-hardening concrete pile body, even if in piling order, device pile penetration etc. Arrangement and method for construction optimization is carried out, stake top region pile body off normal, or broken pile, pile body concrete disintegration, weak interlayer etc. still occurs Disease, have a strong impact on the pile quality and load-carrying properties of present walling pile;And cast-in-situ concrete thin-wall stake week weak soil is easily by overlying lotus The reasons such as load, WATER LEVEL CHANGES cause consolidation settlement, so as to produce larger negative friction, reduce the bearing capacity of stake and increase work After settle.
In order to improve the load-carrying properties of drainage pile and pile quality, more and more people select another concrete drainage pile Construction method, i.e., make concrete drainage pile using prefabrication, and so-called prefabrication refers to the aggregate (gravelstone for selecting appropriate grading Son) and cement, the permeable pile tube that appropriate reinforcing bar is prefabricated into certain length is equipped with, is sent into after prefabricated pile with immersed tube in soil, its Surrounding fills net sand, then extracts immersed tube.
But the concrete drainage pile being made using prefabrication is applying man-hour requirement immersed tube, is also needed after installing Immersed tube is extracted, process is more in whole work progress so that whole operation process is very cumbersome, reduces installation coagulation The efficiency of native drainage pile.
Utility model content
The purpose of this utility model is to provide a kind of precast concrete drainage pile, can letter when installing concrete drainage pile Change operating procedure, improve installation effectiveness.
In order to achieve the above object, base case of the present utility model provides a kind of precast concrete drainage pile, including pre- Permeable concrete pipe processed, the prefabricated permeable concrete pipe is interior provided with the precast concrete pile core coordinated with it, described prefabricated Water coagulation soil tube top portion is provided with overflow launder, and the bottom of overflow launder is communicated with drainage channel, and drainage channel extends upward through prefabricated permeable Pipe of concrete;The precast concrete pile core bottom is provided with the core point of cone, and core point is placed in outside prefabricated permeable concrete pipe Portion.
The principle of this base case is:During installation, design according to demand first the diameter of prefabricated permeable concrete pipe with And length, then precast concrete pile core is installed in the prefabricated permeable concrete pipe after the completion of design, installation is combined Precast concrete drainage pile be inserted directly into ground in the way of core point is towards ground, stable installation is realized, in ground Water is directly entered prefabricated permeable concrete pipe and flowed out from drainage channel, while the water at top also can flow into draining from overflow launder and lead to Road.
The beneficial effect of this base case is:By precast concrete pile core and prefabricated permeable concrete pipe knot in this programme It is combined, while sets core point to be inserted directly into ground in precast concrete pile core bottom, can is directly overall when mounted Installed, it is not necessary to borrow immersed tube, when mounted can disposable installation, the step of simplifying installation operation, improve Installation effectiveness.
Scheme two:Scheme is preferred based on this, and the core point is structure as a whole with precast concrete pile core.
The core point that precast concrete pile core bottom is integrally formed cone can improve the sharp intensity of core, avoid core point from making It is broken off during, while the core point formed using integrally formed mode also can be firmer.
Scheme three:This is preferred for scheme two, and the diameter of the core pointed tip port is more than prefabricated permeable concrete pipe Internal diameter..
When precast concrete drainage pile inserts underground, core point insertion underground can be by upward resistance, core point the widest part Diameter be more than prefabricated permeable concrete pipe internal diameter, it is possible to prevente effectively from core point be squeezed into during insertion it is prefabricated permeable Cause core point can not normal work inside pipe of concrete.
Scheme four:This is preferred for scheme three, and the core point surface is hinged with installing plate.
Because precast concrete drainage pile is during ground end is inserted, installing plate will be turned upwards by the resistance of soil It is dynamic so that installing plate with core is pointed forms an angle, installing plate can block drainage channel bottom, prefabricated so as to avoid Soil enters drainage channel to concrete drainage pile during insertion, ensures that whole drainage channel keeps clear, and improves draining effect Fruit
Scheme five:This is preferred for scheme four, and concrete jacket cylinder, concrete are cased with outside the prefabricated permeable concrete pipe Sleeve bottom is inclined-plane.
In insertion, concrete sleeve can loosen soil, therefore whole precast concrete drainage pile can be directly smooth Insertion ground end.
Scheme six:This is preferred for scheme five, and the drainage channel is vertical drainage channel.
Vertical drainage channel can be such that the water of underground is flowed out rapidly directed along drainage channel, lead to compared to inclined draining Road, current are shorter in the time that drainage channel flows, the rate of outflow faster, so as to improve the draining of precast concrete drainage pile Effect and the reliability of work.
