Specific embodiment
Below in conjunction with specific embodiment, describe the invention in detail.
Specific embodiment one:
According to Fig. 1 to Fig. 3, the present invention provides a kind of reinforced concrete structure static state noiseless method for dismounting, including Following steps:
Step 1: using static crushing technology, blasthole be arranged on reinforced concrete member to be removed, is packed at blasthole Concrete static breaking agent, is expanded by static breaking agent, spalling concrete, exposes the skeleton of reinforcing bar 1 to be removed, it is described to Dismounting reinforcing bar 1 is horizontality;
Step 2: one horizontal plastic slot 2 of installation is respectively set at the both ends of reinforcing bar 1 to be removed, by horizontal plastic slot 2 Opening upwards, grooves on two sides pass through reinforcing bar 1 to be removed and are suspended on reinforcing bar 1 to be removed;
Step 3: it is using plastic ties 6 that the horizontal 2 top semi-girder of plastic slot and reinforcing bar 1 to be removed is fixed, using glue Mud 5 blocks the horizontal groove 2 with 1 contact surface vacancy of reinforcing bar to be removed;
Step 4: dilution heat of sulfuric acid 4 is poured into the horizontal plastic slot 2;
Step 5: after dilution heat of sulfuric acid 4 in horizontal plastic slot 2 and reinforcing bar 1 to be removed chemically react, steel is realized The Statical pattern of muscle and dismounting.
Static crushing technology is used first, and blasthole is set in reinforced concrete member to be removed, it is broken to be packed into concrete static state Broken dose, spalling concrete is expanded by static breaking agent, concrete static crushing exposes framework of steel reinforcement to be removed.Secondly, One static crushing device of end reinforced each setting to be removed.For the static crushing device of reinforcing bar, composition includes wait tear open Except reinforcing bar 1, horizontal plastic slot 2, vertical plastic slot 3, dilution heat of sulfuric acid 4, clay 5, plastic ties 6, lateral plastic dam 7, Bottom plastic end plate 8, lateral baffle card slot 9.The construction method of reinforcing bar static state fracture device: when being crushed to horizontal reinforcement, Horizontal plastic slot 2 is placed in such a way that opening upwards, grooves on two sides pass through reinforcing bar 1 and are suspended on reinforcing bar 1;Using modeling Expect rope 6 by groove top semi-girder and 1 bundled fixed of reinforcing bar;The place of grooves on two sides and 1 contact surface vacancy of reinforcing bar uses clay 5 It smears and blocks;Dilution heat of sulfuric acid 4 is poured into horizontal plastic slot 2, reinforcing bar 1 is flooded.It waits in horizontal plastic slot 2 Dilution heat of sulfuric acid 4 chemically reacted with reinforcing bar 1, destroy reinforcing bar 1 by chemical attack, realize the static fracture of reinforcing bar with It removes.Realize static state, noiseless that reinforced concrete structure removes overall process.
The spacing of length, width, height mainly between bar diameter to be broken and reinforcing bar is related, is mainly used to surround steel Muscle places sulfuric acid solution.The width of plastic slot side or bottom opening, depth, the width and height of semi-girder mainly with to The diameter of fracture reinforcing bar is related, and principal security reinforcing bar to be broken may pass through the opening of groove, and can block reinforcing bar with clay and open Gap between mouthful.According to the diameter and spacing of reinforcing bar 1 to be removed, the length of horizontal plastic slot 2 and vertical plastic slot 3 is determined Degree, width and height.
According to the diameter of reinforcing bar 1 to be removed, the width of horizontal 2 side opening of plastic slot, depth and semi-girder are determined Width, the width of depth and semi-girder, height at width, height, and the bottom opening of vertical plastic slot 3.
Specific embodiment two: as shown in Figures 4 to 7, when reinforcing bar to be removed be vertical state, vertical reinforcing bar is carried out brokenly When broken, vertical plastic slot 3 is placed in such a way that opening upwards, bottom groove pass through reinforcing bar 1 to be removed;Using plastic ties 6 by bottom groove semi-girder and 1 bundled fixed of reinforcing bar to be removed;Bottom groove and the place of 1 contact surface vacancy of reinforcing bar to be removed are adopted It is smeared and is blocked with clay 5;Dilution heat of sulfuric acid 4 is poured into vertical plastic slot 3, the vertical steel to be removed of 3cm to 5cm is flooded Muscle 1.Static crushing device for being crushed reinforcing bar installs.Finally, waiting the dilute sulfuric acid in vertical plastic slot 3 molten Liquid 4 is chemically reacted with reinforcing bar 1 to be removed, destroys reinforcing bar 1 to be removed by chemical attack, realizes the static fracture of reinforcing bar With dismounting.Realize static state, noiseless that reinforced concrete structure removes overall process.
The above is only the preferred embodiment of reinforced concrete structure static state noiseless method for dismounting, armored concrete The protection scope of structure static state noiseless method for dismounting is not limited merely to above-described embodiment, all technical solutions belonged under thinking It all belongs to the scope of protection of the present invention.It should be pointed out that those of ordinary skill in the art, not departing from original of the invention Several improvements and changes under the premise of reason, such modifications and variations also should be regarded as protection scope of the present invention.
