Embodiment Construction
[0046] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0047] This example uses the steel sheet pile grid island wall of the artificial island described in the background technology section as the corresponding construction project to specifically illustrate the implementation process of the on-site splicing method of the large cylinder main grid sheet pile 1 / 4 cylinder of the lattice type steel sheet pile.
[0048] In this example, the implementation of the project has the following conditions:
[0049] 1) The height limit of the construction area. The entire construction area is located in the height limit area of the airport, and the height limit of the construction site of the large cylinder of lattice steel sheet piles is between +30mPD~+60mPD, and the selection of construction equipment is g...

The invention discloses a multifunctional tooling bracket for assembling and disassembling main lattice cylinder positions of large cylinders of lattice steel sheet piles. The multifunctional tooling bracket comprises a base support pile, an upper support base bracket fixedly arranged on the base support pile and is used for supporting four groups of 1 / 4 circle-shaped steel sheet pile preassembling pieces and assembling the large cylinders of the lattice steel sheet piles, a lifting device arranged on the upper support base bracket and used for driving the 1 / 4 circle-shaped steel sheet pile preassembling pieces to lift on the upper support base bracket, a rotation device arranged on the upper support base bracket and used for driving the 1 / 4 circle-shaped steel sheet pile preassembling pieces to rotate on the upper support base bracket, and an airbag expanding device arranged on the upper support base bracket and used for compensating a preserved gap between the tooling bracket and the steel sheet piles after the steel sheet piles are assembled and folded, so that the support base bracket can be used for effectively supporting the steel sheet piles. The multifunctional tooling bracket can be used for effectively assembling and constructing the main lattice cylinder positions of the large cylinders of the lattice steel sheet piles on a construction site under the requirements of construction period and site condition with limits of upper, lower, left and right positions during the construction of an artificial island.
Description
technical field [0001] The invention relates to a construction technique for a large cylinder main grid of a lattice-type steel sheet pile, in particular to a tooling bracket used for installation and construction of a large cylinder main grid of a lattice-type steel sheet pile. Background technique [0002] Artificial islands are generally artificially built land in shallow waters near the coast. As a place for offshore operations or other purposes, most of them are connected to the shore by trestles or undersea tunnels. In a coastal country with developed modern industry, the dense population and crowded cities along the coast have greatly restricted the further development and construction of new enterprises and public facilities, and the problems of residence, traffic, noise, water and air pollution in the original city itself are also difficult. solve. Therefore, the construction of artificial islands has changed or improved the above-mentioned difficult problems. Art...
