Method for installing large pipe fittings in narrow space

Abstract

The invention discloses a method for installing large pipe fittings in a narrow space. The method includes the following steps that firstly, two sets of manual hoist lifting brackets are installed onparts to be installed of the pipe fittings inside a buried culvert, and pipe pillows are placed at the wall of the buried culvert; secondly, lifting equipment is started to transport the pipe fittingsto a culvert port, the distance extending to the culvert is at least 1 / 2 of the pipe length, and the extended part is placed on a trackless trolley; thirdly, trackless trolley equipment is utilized to transport the pipe fittings to the lower portions of the installation positions of the pipe fittings of the buried culvert; fourthly, the two sets of the manual hoist lifting brackets are used for lifting the pipe fittings to the same height, and the trackless trolley is moved away; fifthly, two sets of hoists are pulled at the same time to slowly place the two pipe fittings on the pipe pillowsat the same descent rate, and then bolts are fastened; and sixthly, the above steps are repeated until installation is completed. After the method is adopted, the problem of pipe fitting installationin-position difficulty is overcome, time limits of construction and installation in the narrow space are shortened, and the productivity is increased.

Description

technical field [0001] The invention relates to a method for installing a large pipe fitting in a narrow space. Background technique [0002] At present, most of the tailings, concentrate conveying pipelines and return water pipelines of our country's ore concentrators are steel pipes with large diameters. Under large space conditions, large pipe fittings can be transported and installed manually in various ways, such as using dump trucks or hoisting method to install. Whether it is dump truck shipment or hoisting installation, it is carried out under the condition of sufficient space and flat terrain, but if you want to install it in a hidden culvert, due to the inaccessibility of the narrow space, the large pipe fittings cannot be transported to the installation site, and the weight of the pipe fittings Large and cannot be transported and installed manually. Contents of the invention [0003] The purpose of the invention is to solve the problem in the prior art that th...
