Lossless pipe penetration construction process

The invention provides a lossless pipe penetration construction process. The lossless pipe penetration construction process includes the steps that firstly, a wheel device is installed on a first pipe bracket fixed to one end of the bottom side of a structural beam; secondly, one end of a pipe is placed on the wheel device installed on the first pipe bracket through a first chain block; thirdly, the pipe is pulled through the first chain block, and the pipe is conveyed to a second pipe bracket fixed to the other position of the bottom side of the structural beam through assistance of a second chain block; fourthly, the pipe is lifted as a whole through the first chain block, and the end, located on the wheel device of the first pipe bracket, of the pipe is made to be away from the wheel device; fifthly, the wheel device installed on the first pipe bracket is detached; sixthly, the pipe is fixed to the first pipe bracket and the second pipe bracket. Damage to the pipe and painting layers on the surfaces of the brackets in the pipe penetration process is eliminated, the brackets are prevented from being deformed in the construction process, the site construction difficulty is lowered, the use number of the chain blocks is reduced, the influences of space obstacles are effectively reduced, and pipe penetration operation is easier and more convenient.
