Description
Technical field
The present invention relates to a kind of bamboo joint pile, in particular to a kind of hollow bamboo joint pile of architectural engineering concrete special.
Background technique
Bamboo joint pile has a wide range of applications in coastal soft clay area, and the clay distribution feature of soft clay area is above to cover weak soil
Layer is thicker, and supporting course is deeper, and foundation soil water content is high, and bearing capacity is lower.Thus, in order to reach the bearing capacity energy of design requirement
Power generally requires long or increase and realize by the way of stake diameter using increasing considerably stake.Pile body sinks in order to prevent, bamboo joint pile
Bottom is often plane, this is relatively elaborate when resulting in driving piles, in addition, in the prior art, bamboo joint pile only leans on surrounding soil layer to it
Extruding force realize fix, thus there is a problem of that stability is bad, after using for a longer period bamboo joint pile be easy to happen inclination,
Phenomena such as shaking.
Patent CN201710171680.7 discloses a kind of bamboo joint pile, belongs to technical field of buildings.It solves existing bamboo joint pile
It is easy to happen the technical problems such as inclination, shaking after using for a longer period.This bamboo joint pile includes pile body, and pile body is cylindrical, pile body
Bottom there is cone boss, the outer diameter at the top of cone boss is greater than the outer diameter of pile body, and pile body has an inner cavity, and inner cavity is from pile body
Top surface extends to the upper surface of cone boss, and several strip grooves one for being through to inner cavity, each item are offered on the outer wall of pile body
Along the axially extending of pile body, each strip groove one is uniformly distributed shape slot one along the circumferential direction of pile body.The present invention also provides a kind of bamboos
The construction method for saving stake, includes the following steps: A, the reaming in soil layer；B, above-mentioned bamboo joint pile is squeezed into the hole expanded；C,
Into the inner cavity of pile body, casting cement is starched.The construction method of this bamboo joint pile can be such that pile body is securely fixed in soil layer, increase
The extraction-resistant behavior of pile body.
Patent CN201420688788.5 discloses a kind of back-up sand bamboo joint pile, and back-up sand bamboo joint pile is connected in a joint manner by more piece
Connect bamboo joint pile and tubular pole and sandstone filler composition of the pile sinking into soil layer.Its construction method is: centered on stake position, on ground
The material storage tube of storage sandstone filler is set, after bamboo joint pile or tubular pole are attached, stake is squeezed into or is pressed into soil layer by stake machine
In, by bamboo joint pile or tubular pole to the frictional force of sandstone filler, by sandstone filling packing between stake and pile soil horizon.The present invention
Back-up sand construction can be fast, easily completed, pile quality and durability are reliable, and conventional method construction in soft clay area can be promoted prefabricated
The super quiet pore pressure rapid dispersion generated when stake accelerates foundation soil consolidation, improves the side friction of soil around pile, and reduce building
Final settlement.
But between the pile body of above-mentioned bamboo joint pile and the basis soil of surrounding, friction is small, so that tubular pole
Bearing capacity is smaller.
