Description
Technical field
The present invention relates to concrete works field, more particularly to a kind of variable diameters bamboo joint type mortar pile.
Background technology
Common prefabricated pile is in cylinder, relatively low with respect to cost, but bending rigidity is poor, by pile quality and pressing pile construction work
Skill has a great influence, and in a wide range of construction, soil compaction effect is obvious, typically preferable in soil property, in the case that surrounding enviroment are relatively easy
Using.
And the application of bored concrete pile is then relatively more extensive, its pile-formation process is more ripe, and expanded diameter range of choice is larger, right
It is applicable in most of base pit engineering, but shortcoming is that bored concrete pile cost itself is higher, especially in the double bored concrete pile of widespread adoption
During Frame retaining structure, its economy is an important factor for having to take into account that, in addition, bored pile piling must be through pore-forming and maintenance
It is longer etc. process, its construction period, there is certain influence for the base pit engineering entirety duration.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of variable diameters bamboo joint type mortar pile.
The present invention is realized with following technical scheme：
The present invention includes a kind of variable diameters bamboo joint type mortar pile, and the variable diameters bamboo joint type mortar pile includes pile body and steel pipe.
Further, the variable diameters bamboo joint type mortar pile by upright pile body and is coaxially disposed inside the pile body
Steel pipe or steel reinforcement cage are formed, and it is in spherical bamboo joint type enlarged footing to have at least two on the pile body, the bamboo joint type enlarged footing
Diameter gradually increases from top to bottom, and the pile body, the steel pipe or steel reinforcement cage and the bamboo joint type enlarged footing are integrally formed structure,
The bottom of the variable diameters bamboo joint type mortar pile has bamboo joint type enlarged footing, and it is in spherical bamboo joint type to have some on the pile body
Enlarged footing, it is spaced apart at a certain distance between each bamboo joint type enlarged footing, spacing distance is not less than 3m, and the bamboo joint type expands
Diameter gradually increases major part from top to bottom.
Further, the diameter for the bamboo joint type enlarged footing that some diameters from top to bottom gradually increase is not less than the stake
1 times of body diameter, while no more than 4 times of the pile body diameter.
Further, the diameter for the bamboo joint type enlarged footing that some diameters from top to bottom gradually increase is not less than the stake
1.5 times of body diameter, while no more than 3 times of the pile body diameter.
Further, by water, cement, sand, flyash and additive, situ configuration forms the cement mortar stated according to a certain ratio,
The ratio of mud is in 0.4-0.5, and cement mortar proportion is in 1.5-1.8.
The beneficial effect that technical scheme provided by the invention is brought is：The stake of variable diameters bamboo joint type cement mortar can utilize pressurization
The mode of slip casting forms several bamboo joint type enlarged footings, and diameter gradually increases bamboo joint type enlarged footing from top to bottom, improves stake
Body rigidity and breakout capacity, and the soil body around stake can be extruded using cement grout in slip casting and reinforced, make pile peripheral earth more
Encryption is real, effectively improves intensity, is widely portable to the fields such as foundation pit enclosure and basement process, has convenient, economic ring of constructing
The advantages that guarantor.
Brief description of the drawings
Fig. 1 is a kind of variable diameters bamboo joint type mortar pile that the present embodiment provides；
Wherein：1- pile bodies, 2- steel pipes or steel reinforcement cage, 3- bamboo joint type enlarged footings.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with accompanying drawing
It is described in detail on step ground.
As shown in figure 1, a kind of variable diameters bamboo joint type mortar pile, it is characterised in that the variable diameters bamboo joint type mortar pile is by straight
Staking out body 1 and the steel pipe being coaxially disposed inside the pile body or steel reinforcement cage 2 are formed, and have at least two on the pile body 1
In spherical bamboo joint type enlarged footing 3, diameter gradually increases the bamboo joint type enlarged footing 3 from top to bottom, the pile body 1, the steel
Pipe or steel reinforcement cage 2 and the bamboo joint type enlarged footing 3 are integrally formed structure.
Preferably, there is bamboo joint type enlarged footing 3 in the bottom of the variable diameters bamboo joint type mortar pile.
Preferably, it is in spherical bamboo joint type enlarged footing 3 to have some on the pile body 1, each bamboo joint type enlarged footing 3 it
Between be spaced apart at a certain distance, spacing distance is not less than 3m, and diameter gradually increases the bamboo joint type enlarged footing 3 from top to bottom.
Preferably, the diameter for the bamboo joint type enlarged footing 3 that some diameters from top to bottom gradually increase is not less than the stake
1.5 times of the diameter of body 1, while no more than 3 times of the diameter of pile body 1.
Preferably, the cement mortar of the pile body 1 is mainly live according to a certain ratio by water, cement, sand, flyash and additive
Configuration forms, and the ratio of mud is in 0.4-0.5, and cement mortar proportion is in 1.5-1.8.
As can be seen that variable diameters bamboo joint type cement mortar stake, improves pile body stiffness and breakout capacity from the present embodiment,
And the soil body around stake can be extruded using cement grout in slip casting and reinforced, make pile peripheral earth more closely knit, effectively improve strong
Degree, is widely portable to the fields such as foundation pit enclosure and basement process, has the advantages that construction is convenient, economic and environment-friendly.
Above disclosure is only preferred embodiment of present invention, can not limit the right model of the present invention with this certainly
Enclose, therefore the equivalent variations made according to the claims in the present invention, still belong to the scope that the present invention is covered.
