Embodiment Construction

[0039] The invention discloses a method for repairing and reinforcing an old wharf. The specific steps are as follows:

[0040] Step 1, erection of the construction platform: the construction platform is required to withstand the construction load and material stacking load, as well as the impact of waves;

[0041] Step 2, chiseling of damaged concrete: the depth, length and slope of chiseling should consider the reinforcement of steel bars and the quality requirements of poured concrete;

[0042] Step 3, rust removal of steel bars: it is required to clean up the rust;

[0043] Step 4, Reinforcement of steel bars: Reinforcement according to the degree of corrosion of the steel bars;

[0044] Step 5, apply rust inhibitor;

[0045] Step 6, install the sacrificial anode;

[0046] Step 7, formwork installation: the formwork installation should leave a concrete pouring port;

[0047] Step 8, apply the concrete interface agent;

[0048] Step 9, Concrete pouring: The production ...

Abstract

The invention provides a method for maintaining and reinforcing old docks, relating to the maintenance of old docks. The method comprises the specific steps as follows: step 1:a construction platform is established; step 2: damaged concrete is removed; step 3: reinforcement is derusted; step 4: rebar is used for reinforcement; step 5: rust retardant agent is brushed; step 6: a sacrificial anode is installed; step 7: a template is installed; step 8: concrete interfacial agent is brushed; step 9: concrete is poured; step 10: carbon fiber is used for reinforcement; and step 11: anti-corrosion paint is coated. The method for maintaining and reinforcing old stocks is simple, the construction platform has reasonable structure, is easy to be established, safety, reliability and excellent anti-wave performance, meanwhile, the method is compatible with practical construction requirement and cost-saving requirement, has ideal effect for maintaining and reinforcing old stocks and facilitates the construction and operation of the workers.

Description

technical field [0001] The invention relates to maintenance of old docks, in particular to a method for repairing and strengthening old docks. Background technique [0002] For old piers built before the 1980s, such as figure 1 As shown, including the wharf surface layer 4, the lower surfaces of the left and right ends of the wharf surface layer 4 are sequentially provided with beams 3, pile caps 2, and piles 1 from top to bottom. Due to the reasons of design standards and construction technology, there have been many serious structural damages, especially coastal wharves, which are severely eroded by seawater chloride ions. With the oxidation of steel bars and cracking of concrete, the safety of wharf structures is seriously threatened. If the old wharf is demolished and rebuilt, the cost will be huge, and the wharf will be required to stop production and construction, which will affect the owner's production. If the reliable wharf maintenance and reinforcement technology...
