Problems solved by technology

Although this method is more economical, it also brings a lot of inconvenience to the tunnel sealing construction, which is mainly reflected in the following aspects: (1) The production of bamboo plywood and the binding construction of steel wire rope are cumbersome
(2) The bamboo plywood is placed at the bottom of the beam. Since the beam body has been erected at this time, it is inconvenient to place the bamboo plywood at the bottom of the beam
(3) Bamboo plywood is suspended and fixed by steel wires, which has poor airtightness and stability, and grout leakage is prone to occur during concrete pouring and vibration

Abstract

The invention discloses a U-shaped beam hoisting hole quick blocking device and a construction method. The U-shaped beam hoisting hole quick blocking device comprises a rubber blocking block, a hammerand limiting rods. The rubber blocking block is of a trapezoidal cylindrical structure with the small-diameter lower end and the large-diameter upper end, and the hammer comprises a hammering barrel,limiting holes and a hammering handle; the hammering barrel is of a cylindrical iron structure with the hollow interior and the closed exterior; the limiting holes are formed in a middle upper area of the hammering barrel, horizontally penetrate through the diameter of the hammering barrel and are formed every a certain distance; the hammering handle is an iron half-ring handle and is welded to the top surface of the hammer, and the limiting rods are circular iron rods and can be inserted in the limiting holes in a penetrating mode.

Description

technical field [0001] The invention relates to the technical field of bridges used in civil engineering, and more particularly relates to a U-shaped beam hoisting hole quick sealing device and construction method. Background technique [0002] With the rapid development of my country's rail transit industry, as an important part of rail transit construction, bridge construction has also been developed accordingly. U-shaped beam is a new type of bridge structure with "U"-shaped thin-walled opening section composed of bottom plate, web plate and flange plate, because of its light structure weight, good noise reduction effect, low building height and high space utilization rate , driving safety, beautiful appearance and other advantages are more and more widely used in urban rail transit construction. [0003] For the construction of U-shaped beams in urban rail transit, it is generally more common to hoist and erect the beams on site after the processing of the prefabricated...
