Abstract
The utility model discloses a suspension device of a shield tunnel draught fan. A longitudinal bolt used for splicing and a longitudinal nut used for splicing are arranged inside a shield duct piece. The suspension device of the shield tunnel draught fan is characterized in that the suspension device comprises a prefabricated steel plate and shape steel. The prefabricated steel plate is fixed on the shield duct piece through the longitudinal bolt and the longitudinal nut, the draught fan is connected with the prefabricated steel plate through the shape steel, and cushioning materials are filled between the shape steel and the shield duct piece. According to the suspension device of the shield tunnel draught fan, other pre-embedded pieces do not need to be pre-embedded in the shield duct piece, the longitudinal bolt used for splicing of the duct piece and the longitudinal nut used for splicing of the duct piece only need to be utilized to fix the prefabricated steel plate on the shield duct piece, and then the prefabricated steel plate and the a draught fan support frame are connected through the shape steel. The suspension device of the shield tunnel draught fan is a connecting form which is fast and convenient to construct, economical, safe and reliable. The suspension device of the shield tunnel draught fan mainly comprises the prefabricated steel plate and the shape steel, wherein the prefabricated steel plate and the shape steel are connected through bolts. The prefabricated steel plate is connected with the shield duct piece through the longitudinal bolt used for the splicing of the duct piece and the longitudinal nut used for the splicing of the duct piece. And the need of fast installation of the draught fan inside a tunnel is met.
Description
Technical field
The utility model relates to the technical field that the shield tunnel blower fan hangs, specifically with blower fan fast, economical, be fixed on shield tunnel blower fan suspension arrangement and hanging method thereof accurately.
Background technology
At present, the tunnel of China's shield construction is more and more, according to the requirement of tunnel ventilation, needs to arrange blower fan in the tunnel.At present shield tunnel adopts that the mode of pre-embedded steel slab is connected with blower fan in the section of jurisdiction more, but because the problems such as the restriction of the factors such as shield duct piece width, hand hole position, Segment assembling method, reinforcement placement and quality control on construction, pre-embedded steel slab size, position, planeness etc. are difficult to reach designing requirement, cause the fan supporter specification not unify completely, installation, later stage operation to blower fan all have adverse effect, have also increased cost and duration simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of efficient, economic, safe shield tunnel blower fan suspension arrangement.
To achieve these goals, the technical solution of the utility model is as follows: a kind of shield tunnel blower fan suspension arrangement, be provided with assembly unit longitudinal bolt and vertical nut in the described shield duct piece, it is characterized in that this suspension arrangement comprises prefabricated steel and shaped steel, this prefabricated steel is fixed on the shield duct piece by this longitudinal bolt and nut, blower fan is connected with prefabricated steel by shaped steel, is filled with padded coaming in the gap between shaped steel and shield duct piece.
The utility model is adjusted into shield tunnel blower fan hanging method pre-embedded steel slab when making in the section of jurisdiction and prefabricated steel is installed when the pipe sheet assembling, be beneficial to blower fan Fast Installation, reduce investment outlay.
