Abstract
The invention discloses an embraced-to-jacked prestressed hollow pipe pile feeder, which comprises an embraced-to-jacked prestressed hollow pipe pile feeder outer sleeve and an inner pile pressing cap, wherein the embraced-to-jacked prestressed hollow pipe pile feeder outer sleeve comprises an outer sleeve, an outer ring flange plate, a top plate, a reinforcing hoop, supports, a baffle plate, an inner ring flange plate and inner plates; the whole embraced-to-jacked prestressed hollow pipe pile feeder outer sleeve is shorter than a pressed prestressed hollow pipe pile; the diameter of the lower end of the outer sleeve is reduced, and the lower end of the inner side of the outer sleeve is connected with the inner ring flange plate; the upper part of the outer sleeve is connected with the outer ring flange plate, and the top part of the outer sleeve is connected with the top plate; the supports are connected with the top plate; the inner plates are arranged inside the supports; the distance between the two inner plates is smaller than the maximum stroke of a pile pressing machine; the two supports are connected through the reinforcing hoop; the inner pile pressing cap comprises a lug plate, a hinge pin, a bottom plate, a baffle plate and a pile pressing positioning device, wherein the pile pressing positioning device is fixed at the lower part of the bottom plate, and the baffle plate is connected with the lug plate by the hinge pin; and the inner plates press the baffle plate. The embraced-to-jacked prestressed hollow pipe pile feeder sinks piles by a jacked manner instead of an embraced manner; and when in construction of a variable-cross-section tubular pile, a clamp is unnecessary to be replaced.
Description
Technical field: the technical field that the present invention relates to is the piling device during the prestressed pipe pile foundation construction in the construction work.
Background technology: at present when the construction work pile foundation construction, the pre-stress hollow pile tube is because its pile quality is good, and pile sinking speed is fast, and the bearing capacity of stake can read on pile press at any time, thereby adopted by a large amount of engineerings at present.According to the building foundation engineering design, pile body will satisfy the effect of the suffered horizontal force of opposing building on top, and vertical bearing capacity, and the top pile body will have enough sectional areas and intensity to meet design requirement when design.The cross section and the arrangement of reinforcement that then can reduce stake in the pile body bottom can meet design requirement, so pile foundation can be designed to the pile foundation of variable cross-section when design.As adopting non-uniform pile, can significantly reduce construction costs, but the pre-stress hollow pile tube is as being designed to the variable cross-section pile body in the engineering; Generally use at present quiet armful press in the piling construction technology and can't realize quick pile sinking; As press non-uniform pile also to need frequent replacing to embrace the pressure anchor clamps, and what these were a large amount of loses time, and construction is very inconvenient; And the top pressing type pile press is fewer on the market, so restricted applying of variable cross-section hollow shell pill.
Summary of the invention: the purpose of this invention is to provide a kind ofly when not changing the anchor clamps of quiet armful of pile press, transfer the hugging pressure type piling to the top pressing type piling, a kind of pre-stress hollow pile tube that can realize the quick piling construction of variable cross-section pile tube is embraced and is changeed the roof pressure Pile feeder.Technical scheme of the present invention is: the present invention includes the pre-stress hollow pile tube and embrace commentaries on classics roof pressure Pile feeder overcoat and interior piling cap; The pre-stress hollow pile tube is embraced and is changeed roof pressure Pile feeder overcoat and comprise outer tube, outer ring flange, top board, reinforcement hoop, support, baffle plate, interior annular flange dish, inner panel, and the pre-stress hollow pile tube is embraced changes roof pressure Pile feeder overcoat total length, lacks than the pre-stress hollow pile tube that institute will press; Outer tube leans on the lower end part diameter to diminish; The outer tube inside lower end is connected with interior annular flange dish, and interior annular flange dish internal diameter is identical with outer tube bottom microcephaly's internal diameter, and the outer tube upper outside is connected with the outer ring flange; Outer ring flange internal diameter is identical with outer tube top large head external diameter; The outer tube top is connected with annular roof plate, and the internal diameter of top board is identical with outer tube microcephaly internal diameter, is furnished with two supports relatively on the top board; The bottom of support is connected with top board is vertical; Each support inboard at interval is fixedly connected with inner panel from top to bottom, and at interval distance is less than the pile press range between per two inner panels, and two supports are connected and fixed through spaced apart reinforcement hoop from top to bottom.Interior piling cap comprises two otic placodes, bearing pin, base plate, two baffle plates, piling locator; The piling locator is fixed on the base plate bottom, is connected with the otic placode of two bottom band circular pin holes above the base plate, is placed with two baffle plates in the middle of two otic placodes; Have circular pin hole on the baffle plate; On the baffle plate on circular hole and the otic placode pin-and-hole size identical, four pin-and-hole centers are on same straight line, the pin-and-hole that bearing pin passes on baffle plate and the otic placode connects; Can place two supports that the pre-stress hollow pile tube is embraced changes roof pressure Pile feeder overcoat with respect to the interior piling cap that support moves downward, the pre-stress hollow pile tube is embraced the inner panel that changes roof pressure Pile feeder overcoat and can be pressed on the baffle plate of interior piling cap.Embracing pile press clamp clamps Pile feeder when the present invention constructs moves down; Pile feeder will be embraced frictional force that pile press anchor clamps and outer tube produce and convert downward pressure into and act on pre-stressed concrete hollow pile tube top, thereby realize transferring the hugging pressure type pile sinking to the roof pressure pile sinking.When the varying cross-section duct pile driving construction, no longer need change quiet armful and press anchor clamps, save the engineering time, can realize quick pile sinking, improve efficiency of construction.The present invention also has advantages such as the processing of being easy to, easy for operation, safe and reliable, maintenance convenient.
