Embodiment Construction
[0019] Such as figure 1 The telescopic pump pipe for super-high-rise concrete filled steel pipe jacking shown includes an outer sleeve 1 and an inner sleeve 2 that are socketed in each other, and one end of the outer sleeve 1 is socketed and symmetrically provided with four pairs of pull stops along the circumferential direction. Plate 3, one end of the inner sleeve sleeve is provided along the ring direction with a pair of pull fixing plates 4 corresponding to the pair of pull baffles 3; In the process of connecting the pump tube, the purpose of connecting the non-standard length pump tube can be achieved by adjusting the length of the telescopic pump tube.
[0020] Such as figure 2 and image 3 As shown, the outer sleeve 1 is composed of two semicircular sleeves, a welding leaflet 6 is installed on one side of the connection part, and a connecting plate 7 is welded on the other side and fixed by bolts 8 . The pull baffle plate 3 on the outer sleeve 1 has a round hole for...

The invention discloses a telescopic pump pipe for super high-rise steel pipe concrete jacking, which comprises an outer sleeve (1) and an inner sleeve (2) which are socketed with each other, and is characterized in that: the outer sleeve (1) covers One end is symmetrically provided with four opposite pull baffles (3) along the circumferential direction, and one end of the inner sleeve sleeve is provided with the opposite pull fixing plate (4) corresponding to the opposite pull baffles (3) along the circumferential direction. ; The pair of pull baffles (3) and the pair of pull fixed plates (4) are respectively connected in series through pull rods (5). The telescopic pump tube connection technology is adopted to avoid non-standard pump tubes by adjusting the length of the telescopic pump tube and quickly connect the pump tube. The method is simple and fast, convenient for installation and disassembly, and saves construction period.
Description
technical field [0001] The invention relates to the field of pump pipe equipment, in particular to a telescopic pump pipe for super high-rise steel pipe concrete jacking. Background technique [0002] For special-shaped super high-rise structures, concrete-filled steel pipe jacking construction, the number of concrete-filled steel pipe columns is large, and the overall structure is irregular. When concrete is poured, the distance between the pump pipe elbow and the feed inlet is different when concrete is poured for different columns. The standard length of each section of the pump pipe is 3m, 2m, 1.5m. When the pump pipe is extended, the total length is non-modulus, and the connection of the pump pipe is extremely difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a telescopic pump pipe for super high-rise concrete filled steel pipe jacking in view of the problem that the distance between the pump pipe e...
