Abstract
The present invention is relevant a kind of method of inclined chimney being carried out integral correction.The present invention uses some jack to insert in the hole of stack leaning face bottom, jack-up chimney (jack-up highly available formula calculate) slowly, chimney bottom by the space of jack-up in, build after the end solidifies with filler, remove jack, hole is mended the jail, last at chimney by the joint portion of jack-up, with several shroud ring and the reinforcing of perpendicular muscle.Chimney after said method is corrected can come into operation safely.The inventive method is simple, and construction safety is simple and easy to do.
Description
The present invention is relevant method of inclined chimney being carried out integral correction.
Newly-built chimney, because the influence of the variation of ground and other natural cause, usually can run-off the straight, as not correcting, chimney is easy to collapse, and this not only influences plant produced, also jeopardizes people's lives and properties, causes heavy losses.
The present inventor is for addressing the above problem, and is engaged in this research, one side find to insert filler if inclined chimney is sunk after more serious the raising, just can reach the purpose of rectification inclined chimney.
The present invention is based on above-mentioned discovery develops, the inventor utilizes several jack, be placed on the bottom of chimney at the stack leaning face, jack-up chimney slowly is through apparatus measures, after chimney set right, insert fillers such as concrete in the chimney bottom gap, remove jack,, reached the purpose of integral correction chimney through said process.
At first according to the height of chimney, with band iron chimney is added some roads shroud ring and perpendicular muscle, to guarantee the whole steadiness of chimney, overall weight according to chimney, earlier with some jack (gross tonnage of jack must greater than the gross weight of chimney), quantity according to required jack, on sinking to more serious half cycle, chimney bottom evenly cuts a hole into several holes, jack is placed in the hole, at jack top and bottom pad upper steel plate, at this moment, with jack slowly with chimney jack-up, according to mathematical similarity triangular relationship principle, jack stand height
H=(chimney bottom diameter D * chimney departs from centre distance S)/(chimney height H)
Through apparatus measures, after chimney is corrected, the bottom by the space of jack-up in, build real solidifying with fillers such as brick and cement concretes after, remove jack, and hole is filled out the jail mend real, last in the jack-up joint portion of chimney, reinforce the chimney after rectification is reinforced through said method with some shroud rings and perpendicular muscle, reached the purpose of the inclination of setting right, can come into operation safely.
Below in conjunction with example the present invention is further described:
Example: the heavy G=15 ton of chimney, high H=47 rice, end outer diameter D=4.74 meter, chimney integral body is knockdown westwards, and the top mouth departs from chimney main shaft S=1.1 rice.
Antidote is as follows:
1. at high 3/4 place of chimney, break 6 on wirerope, be evenly distributed on around the chimney with wire rope.
2. with five jack (its gross tonnage＞150 ton), the jack stand height is:
h＝4.74×1.1÷47＝0.11（m）。
3. on the chimney wall of stack leaning face bottom, make a call to five cuts equably, jack is put into cut, the jack top and bottom are filled up respectively and are put a block plate, and five jack pressurize simultaneously, with stack leaning face bottom jack-up 11-12 centimetre (available apparatus measures).
4. after the chimney jack-up, with brick body cement structures the space of jack-up is mended real, solidify a week after, jack is removed, cut tamps mends the jail.
At chimney by the joint portion of jack-up, reinforce with some roads shroud ring and perpendicular muscle.
After the said method processing, chimney is through measuring, and the inclination of setting right produces a desired effect.
Claims (3)
1, a kind of method of integral correction inclined chimney is characterized in that comprising following step:
A). on the half cycle of stack leaning face bottom, dig out plurality of holes equably.
B). some jack are inserted in the bottom hole of stack leaning face, slowly the jack-up chimney.
C). between chimney is by the jack-up space, adds filler and mend real.
2, according to described step in the claim 1, can further comprise, add several shroud ring and perpendicular muscle on by the joint portion of jack-up at chimney.
3, according to described some jack in the claim 1, its gross tonnage is greater than the chimney gross weight.
