The invention provides a large and light-weight stereo type construction temporary boundary wall and a construction method thereof. The large and light-weight stereo type construction temporary boundary wall comprises wall plates, column caps and
pile foundations, wherein each
wall plate is formed by a left upright post, a right upright post, an upper cross beam, a lower cross beam and a web plate; bases are welded at the bottoms of the left upright post and the right upright post; each
pile foundation is formed by a vertical downward erect
pile, a pedestal welded on the top surface of the erect pile, and a cross arm; and the center of the top of the erect pile and the center of a pedestal plane are welded together in an alignment way. The construction method comprises the following steps: firstly performing the operation of positioning, measuring and line releasing, nailing the first pile foundation on the left side, continuously nailing the second pile foundation on the left side, mounting the left-side first
wall plate, placing a left base and a right base of each
wall plate on the pedestals of the left-side first pile foundation and the second pile foundation respectively, and mounting the second wall plate in the same way, so as to complete the mounting of the whole boundary wall in sequence. According to the large and light-weight stereo type construction temporary boundary wall and the construction method thereof which are provided by the invention, the large and light-weight stereo type construction temporary boundary wall is light , small in volume, convenient to transport, and suitable for being mounted on viscous-soil ground, good in mounting self-stability, and simple in mounting and dismounting, industrialized production can be achieved, labor and time are saved, turnover use is realized, construction cost can be reduced, and environmental
pollution is less.
