specific Embodiment 1

[0029] according to Figure 1 to Figure 3 As shown, the present invention provides a static noiseless demolition method for reinforced concrete structures, comprising the following steps:

[0030] Step 1: Using static crushing technology, set blastholes on the reinforced concrete components to be removed, fill the blastholes with concrete static breakers, expand and crack the concrete through the static breaker, and expose the skeleton of the steel bars 1 to be removed. State that the steel bar 1 to be removed is in a horizontal state;

[0031] Step 2: Install a horizontal plastic groove 2 at both ends of the steel bar 1 to be removed, open the horizontal plastic groove 2 upwards, and pass the grooves on both sides through the steel bar 1 to be removed and hang it on the steel bar 1 to be removed;

[0032] Step 3: Fix the top outrigger of the horizontal plastic groove 2 with the steel bar 1 to be removed by using plastic rope 6, and seal the vacant part of the contact surface...

specific Embodiment 2

[0038] Specific embodiment two: as Figure 4 to Figure 7 As shown, when the steel bar to be removed is in a vertical state, when the vertical steel bar is broken, the vertical plastic groove 3 is placed in such a way that the opening is upward and the bottom groove passes through the steel bar 1 to be removed; The outrigger of the bottom groove is bound and fixed with the steel bar 1 to be removed; the gap between the bottom groove and the steel bar 1 to be removed is smeared and sealed with glue 5; the dilute sulfuric acid solution 4 is poured into the vertical plastic groove 3 and submerged for 3cm The vertical steel bar 1 to be removed to 5cm gets final product. The static crushing unit for crushing steel bars has been installed. Finally, wait for the dilute sulfuric acid solution 4 in the vertical plastic groove 3 to chemically react with the steel bar 1 to be removed, and destroy the steel bar 1 to be removed by chemical corrosion, so as to realize the static breaking an...

Abstract

The invention discloses a reinforced concrete structure static noiseless disassembly method which comprises the following steps of enabling a skeleton of a steel bar (1) to be disassembled to be exposed by adopting a static cracking technology; mounting a horizontal plastic groove (2) at each of the two ends of the steel bar (1) to be disassembled, enabling the horizontal plastic grooves (2) to penetrate through the steel bar (1) to be disassembled, and hanging the horizontal plastic grooves (2) on the steel bar (1) to be disassembled; fixing the horizontal plastic grooves (2) to the steel bar(1) to be disassembled by adopting plastic ropes (6) respectively, and blocking a vacancy of the contact surface of each horizontal plastic groove (2) with the steel bar (1) to be disassembled by adopting daub (5); pouring a dilute sulphuric acid solution (4) into each horizontal plastic groove (2); and after the dilute sulphuric acid solution (4) in each horizontal plastic groove (2) generates chemical reaction with the steel bar (1) to be disassembled, realizing that a whole disassembly process of a reinforced concrete structure is static and noiseless.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete demolition in civil engineering, and relates to a static noiseless demolition method for reinforced concrete structures. Background technique [0002] At present, my country's urban construction area exceeds 35 billion square meters, and the urban population is nearly 800 million. The urban buildings and population are dense, and the construction area demolished in my country exceeds 400 million square meters every year. The demolition of building structures in urban densely built areas has a relatively large safety risk, and the impact of accidents is severe. At present, conventional demolition methods mainly include manual demolition, mechanical demolition, blasting demolition, etc. The management of manual demolition and mechanical demolition is extensive, the overall technical level is not high, and the demolition efficiency is low. The dust, noise pollution and vibration of blas...
