Installation method of slot type prefabricated part of assembly type long-pile wharf

Abstract

According to the installation method of the assembled high-pile wharf slot type prefabricated component, the slot type component is a component with a built-in cavity, the built-in cavity is cylindrical, the circle center of the built-in cavity coincides with the center of a pile foundation, the diameter of the built-in cavity is 200-400 mm larger than that of the pile foundation, the pile foundation stretches into the component cavity, and the installation method comprises the steps that (1) a ship is in place; (2) erecting and installing an operation platform; (3) hoisting the components by the crane ship; (4) the component is rotated by 90 degrees in the longitudinal direction and the transverse direction; (5) the component is transversely hoisted to a mounting position; (6) falling and mounting the component; (7) adopting a pile top self-supporting method for the slot type component; and (8) after the slot type component is installed, concrete or grouting materials are poured in the built-in cavity of the component in time, so that stable post-poured joint connection is formed. The method is accurate in installation and positioning, use of a large number of waling supporting systems is avoided, and the construction cost is reduced; construction is efficient and convenient, and human input is avoided.

Description

Technical field [0001] The present invention relates to a high pile dock engineering, in particular an installation method of a prefabricated prefabricated member of the prefabricated high pile dock slot type. Background [0002] The existing slot-type prefabricated component prefabricated structure is a new type of component with built-in cavity made of concrete, steel, steel structure and other materials, which is applied to the prefabricated high pile dock project, which is directly connected with the pile foundation, and the horizontal row pile foundation is connected into a whole, which is equivalent to the cast-in-place pile cap, cast-in-place cap beam, etc. The pile foundation is extended 1m into the member, and it is a problem to accurately locate and install such a slot-type component. [0003] In the dock project, there is no construction method of the upper component and the pile foundation socket connection, in the prefabricated bridge project, the prefabricated pier...

AI Technical Summary

Problems solved by technology

[0003] In wharf engineering, there is no construction method of slot-type connection between the upper member and pile foundation. In prefabricated bridge engineering, the prefabricated pier body and cap beam, pile and cap, etc. adopt the slot-type installation method, but the bridge engineering The slot-type installation is different from the slot-type prefabricated component installation involved in the patent of the present invention. The bridge project is constructed on land, and the position tolerance of the substructure is small. Influence, unable to timely and accurately control the slotted components
