Positioning tower used for mounting multilayer cubic blocks in deep water

Abstract

The invention relates to a positioning tower used for mounting multilayer cubic blocks in deep water. The positioning tower comprises a concrete pier, a tower body fixed on the concrete pier and a tower crane mounted at the top end of the tower body, wherein the tower body comprises at least three truss frame towers which are sequentially and fixedly connected from the bottom up; the tower crane comprises a triangular truss frame, a traveling crane and a balancing weight, the triangular truss frame is arranged in a horizontal direction and rotationally mounted at the top end of the tower body; the traveling crane is glidingly mounted at one end of the triangular truss frame in the horizontal direction, a drop hammer is fixedly connected onto the traveling crane through a steel wire rope, and the balancing weight is fixedly mounted at the other end of the triangular truss frame in the horizontal direction; and a plurality of horizontal rods arranged at equal intervals are fixed on one side, corresponding to the traveling crane, of the tower body in a vertical direction. According to the embodiment of the invention, the positioning tower used for mounting the multilayer cubic blocks in the deep water is provided and can effectively control the accuracy of a leading edge line, a slit width, intersection and horizontal and vertical process grooves of the cubic blocks; and the mounting accuracy is greatly improved to meet a requirement for the process accuracy.

Description

technical field [0001] The invention relates to the field of construction, in particular to a positioning tower for deep-water multi-layer block installation. Background technique [0002] In the construction process of building a gravity block wharf, some wharfs have stricter requirements. It is necessary to adopt a suitable positioning scheme to control the precision of the front line, slit width, misalignment and square horizontal and vertical process grooves. However, the commonly used underwater fixed-point pull-to-baseline measurement method in the prior art is not universal. In some waters, the barge sways to the left and right to a large extent under the influence of the swell, the weight or the measuring rod sways in the water, and the diver is underwater. It is difficult to determine the exact position, and the lead point error is large; in addition, the components are easy to touch the installation baseline during the installation process, resulting in the displa...

Problems solved by technology

However, the underwater fixed-point baseline measurement method commonly used in the prior art is not universal. In some waters, the barge is affected by the swell and swings from side to side with a large range, and the weight or measuring rod swings in the water. It is difficult to determine the exact position, and the error of the lead point is large; in addition, the components are easy to touch the installation baseline during the installation process, causing the concrete positioning pier to shift
