Embodiment Construction

[0042] refer to figure 1 , in this embodiment, the middle and lower beams of the old wharf 1 have been corroded, and the minimum reinforcement ratio of the longitudinally stressed steel bars cannot meet the requirements of JTS151-2011 (Code for Design of Concrete Structures for Water Transport Engineering), so reinforcement is required.

[0043] First, clean the lower surface of the lower crossbeam, perform surface decontamination, chiseling and other operations to obtain a clean construction surface 2 .

[0044] refer to figure 2 and image 3 , the width of the lower end of the lower crossbeam is 1.4m, and holes are respectively drilled on the two sides of the lower crossbeam 12 to obtain jacks 13 with a length of 0.3m.

[0045] The upper end of the paired "凵" type Φ18@400 stirrup 21 is inserted into the jack 13, and the lower end is located below the lower surface of the lower crossbeam 12. If the stirrup 21 is shorter, it is connected through the Φ18@400 steel bar 25 and...

Abstract

The invention provides a novel aged wharf upgrading and reinforcing method and an upgraded and reinforced wharf. A support pile is arranged beneath a lower crossbeam, two sides of the lower crossbeam are provided with insert holes, one ends of hoops in pairwise are inserted into the insert holes, and the other ends of the hoops are arranged below the lower crossbeam. The hoops of each pair are connected beneath the lower crossbeam respectively; rebars are usually arranged between the hoops and the lower surface of the lower crossbeam. A concrete layer is additionally arranged and at least arranged on the surface of a part of the lower crossbeam and wraps the hoops and the rebars. A thin jetting concrete structure (containing rebars) wraps the lower surface of the lower crossbeam, safety and durability of the structure can be enhanced, and collision resistance and seismic resistance are improved. In this case, berthing capacity of the wharf is greatly improved.

Description

technical field [0001] The invention relates to an old wharf reconstruction method, in particular to a method for upgrading and strengthening the lower beam structure of the wharf, and an upgrading and strengthening wharf. Background technique [0002] The wharf, also known as the ferry, is a long embankment extending from the shore to the water. It is a building specially designed for passengers to get on and off, and cargo loading and unloading by the sea and rivers. It is usually found in commercial cities with developed water and land transportation. Among them, the trestle-type wharf, also known as the hollow-type high-pile wharf, is an offshore wharf connected to the shore by the trestle bridge, and is also a professional wharf for oil, coal, ore, etc., including a convex lower beam, and the lower beam is supported Structure, track beams (longitudinal beams) are erected on both sides of the lower beam. [0003] Generally speaking, the lower beam of the wharf is locate...
