Abstract
The utility model belongs to the technical field of the construction of the vertical prestressed pipe of continuous beam, for solve adopting current continuous beam vertical prestressing mud jacking pore lower extreme mud jacking, the technical problem of big, the mud jacking inefficiency of the construction degree of difficulty provided a continuous beam vertical prestressing mud jacking closed tube when mud jacking was carried out to the mode ventilated in the top, two adapter sleeve about including are provided with a connecting pipe between two adapter sleeve, the both ends of connecting pipe respectively about with two adapter sleeve be linked together about, two adapter sleeve's bottom and be provided with an anchor backing plate respectively, a through -hole has been offered to the centre of anchor backing plate, the diameter phase -match of finish rolling reinforcing bar in the diameter of through -hole and the pore. The utility model discloses simple manufacture, low cost with two vertical prestressed duct bottom UNICOMs, says the top mud jacking at a root hole during mud jacking, and another root hole says that top ventilates, and a mud jacking can be pressed and annotated two root hole ways, has reduced the mud jacking number of times, has reduced the construction degree of difficulty, has improved the mud jacking quality.
Description
Technical field
The utility model belongs to continuous beam vertical prestressing technical field of pipeline construction, is specifically related to a kind of continuous beam vertical prestressing mud jacking cross over pipe.
Background technology
Continuous beam vertical prestressing mud jacking duct adopts lower end, duct mud jacking usually, the mode of top ventilation carries out mud jacking, to need pneumatic mortar machine to move in case beam (or lengthen madjack pipe, mud jacking hole leading-in box beam is inner), execute man-hour requirement to operate in case back portion and bottom simultaneously, work in coordination with construction, difficulty of construction is large, mud jacking efficiency is lower.
Summary of the invention
The utility model adopts lower end, existing continuous beam vertical prestressing mud jacking duct mud jacking for solving, and when the mode of top ventilation carries out mud jacking, large, the inefficient technical problem of mud jacking of difficulty of construction, provides a kind of continuous beam vertical prestressing mud jacking cross over pipe.
The technical solution adopted in the utility model is as follows:
A kind of continuous beam vertical prestressing mud jacking cross over pipe, comprise two splicing sleeves in left and right, the described internal diameter of two splicing sleeves and the external diameter in duct match, a tube connector is provided with between two splicing sleeves, the two ends of described tube connector are connected with two, left and right splicing sleeve respectively, the length of tube connector and the distance in adjacent two ducts match, the bottom of left and right two splicing sleeves is respectively arranged with an anchor plate, the centre of anchor plate offers a through hole, and in the diameter of described through hole and duct, the diameter of finish rolling reinforcing bar matches.
Described splicing sleeve and tube connector all adopt steel pipe manufacturing.
When the utility model uses, only cross over pipe of the present utility model need be arranged on the bottom in adjacent two ducts, then fix with nut, at top, a root hole road mud jacking during mud jacking, ventilate in another top, root hole road, mud jacking can while pressure injection two root hole road.
The beneficial effects of the utility model: the utility model makes simple, with low cost, the utility model is by UNICOM bottom two vertical prestressing force openings, adopt U-shaped design, at top, a root hole road mud jacking, ventilate in another top, root hole road, mud jacking can pressure injection two root hole road, reach and reduce mud jacking number of times, improve execution conditions, reduce difficulty of construction, improve the effect of squeezing quality.
