Abstract
本发明涉及在高炉大修时高炉炉底的混凝土基础的切割单元完成后，对切割单元充填注浆材料的一种工艺方法。一种在混凝土切割单元内充填注浆材料的方法，其特征是：(1)将铝塑复合材料囊放入切割单元混凝土缝内，在切割单元外面，铝塑复合材料囊的两端装有橡胶垫，橡胶垫外侧一端为进灌嘴，另一端为出浆嘴；(2)进灌嘴连接进浆管，出浆嘴连接回浆管；(3)进浆管和回浆管接灌浆系统；(4)操作时对铝塑复合材料囊采用高压注浆法将充填材料注入铝塑复合材料囊中，使铝塑复合材料囊压附在混凝土缝内表面，将充填材料与混凝土隔离。本发明将充填材料注入铝塑复合材料囊充填切割单元内，硬化后与混凝土容易脱离，并能支撑高炉炉体正常运行。
The invention relates to a process method for filling the cutting unit with grouting material after the cutting unit of the concrete foundation at the bottom of the blast furnace is completed during the overhaul of the blast furnace. A method for filling grouting material in a concrete cutting unit, which is characterized in that: (1) putting the aluminum-plastic composite material bag into the concrete joint of the cutting unit, and outside the cutting unit, two ends of the aluminum-plastic composite material bag are equipped with Rubber pad, one end of the outer side of the rubber pad is the inlet nozzle, and the other end is the slurry nozzle; (2) The inlet nozzle is connected to the slurry inlet pipe, and the slurry outlet nozzle is connected to the slurry return pipe; (3) The slurry inlet pipe and the slurry return pipe are connected to the grout (4) During operation, the filling material is injected into the aluminum-plastic composite bag by high-pressure grouting method, so that the aluminum-plastic composite bag is pressed and attached to the inner surface of the concrete joint, and the filling material is isolated from the concrete. In the invention, the filling material is injected into the aluminum-plastic composite material bag filling and cutting unit, which is easily separated from the concrete after hardening, and can support the normal operation of the blast furnace body.
Description
(1) technical field
After the cutter unit that the present invention relates to the concrete foundation at the bottom of the State of Blast Furnace when blast furnace overhaul is finished, to a kind of process of cutter unit filling and grouting material.
(2) background technology
When blast furnace overhaul,, proposed a kind ofly under the blast furnace normal production conditions, earlier basic round platform parts transversely has been cut off, at short notice cut-off parts has been released after blast furnace stops production, finished the transformation on residue basis then at the appointed time for shortening construction period.Therefore in the disintegration process at the bottom of the State of Blast Furnace, need each unit of concrete foundation is cut, cutter unit needs to carry out backfill with filler after finishing cutting, carries out ordinary production thereby support blast furnace.Finish cutter unit, need on concrete foundation, hole, and cut with the diamond rope.To the requirement after the cutter unit back-filling underfill material is should separate easily with concrete foundation after filler hardens, and can support blast furnace and normally move.
(3) summary of the invention
The object of the present invention is to provide a kind of in concrete cutting unit the method for filling and grouting material, this method is injected filler in the aluminium plastic composite material capsule filling cutter unit, the sclerosis back breaks away from easily with concrete, and can support blast furnace and normally move.
The present invention be achieved in that a kind of in concrete cutting unit the method for filling and grouting material, it is characterized in that:
(1) the aluminium plastic composite material capsule is put into cutter unit concrete seam, in the cutter unit outside, rubber pad is equipped with at the two ends of aluminium plastic composite material capsule, and rubber pad outside aluminium plastic composite material capsule one end is for advancing Guan Zui, and the other end is a slurry outlet nozzle;
(2) advance to irritate mouth and connect inlet pipe, slurry outlet nozzle connects return pipe;
(3) inlet pipe and return pipe connect grouting system;
Adopt the high-pressure slip-casting method that filler is injected the aluminium plastic composite material capsule to the aluminium plastic composite material capsule when (4) operation begins, make the aluminium plastic composite material bag pressure be attached to concrete seam inner surface, filler and concrete are isolated.
The present invention injects filler in the aluminium plastic composite material capsule filling cutter unit, the aluminium plastic composite material capsule separates filler and concrete foundation, form release surface, can support the normal operation of blast furnace after the filler sclerosis, do not influence the ordinary production of blast furnace.When treating blast furnace stopping production overhaul, the blast furnace foundation and the blast furnace on cutting unit top are released, just can be carried out extending capacity reformation, can shorten the overhaul duration greatly remaining the basis.
(4) description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the method schematic diagram of filling and grouting material in concrete cutting unit;
Fig. 2 is the lateral view of filling and grouting material in concrete cutting unit.
Among the figure: 1 aluminium plastic composite material capsule, 2 advance Guan Zui, 3 slurry outlet nozzles, 4 rubber pads, the boring of 5 dividing elements, 6 concrete, 7 fillers.
(5) specific embodiment
Referring to Fig. 1, Fig. 2, a kind of in concrete cutting unit the method for filling and grouting material, the steps include:
(1) aluminium plastic composite material capsule 1 is put into cutter unit concrete 6 seams, can be put three aluminium plastic composite material capsules 1 side by side in cutter unit concrete 6 seams; In the cutter unit outside, rubber pad 4 is equipped with at the two ends of aluminium plastic composite material capsule 1, and rubber pad 4 outside aluminium plastic composite material capsule 1 one ends are for advancing to irritate mouth 2, and the other end is a slurry outlet nozzle 3;
(2) advance to irritate mouth 2 and connect inlet pipe, slurry outlet nozzle 3 connects return pipe;
(3) inlet pipe and return pipe connect grouting system;
Adopt the high-pressure slip-casting method that filler 7 is injected aluminium plastic composite material capsules 1 to aluminium plastic composite material capsule 1 when (4) operation begins, aluminium plastic composite material capsule 1 is pressed be attached to concrete 6 seam inner surfaces, filler 7 and concrete 6 are isolated.Also solved simultaneously the coarse problem of flow interface.
Grouting system should be accomplished: slurries should be able to be filled into whole concrete seam from bottom to top equably; Grouting pipeline and pulp facility and seam face should be unimpeded; Grouting pipeline should straight, unimpeded, few elbow.
Advance to irritate mouth 2 and slurry outlet nozzle 3 and aluminium plastic composite material capsule 1 in the grouting pipeline are used pressure bind mode and sealing; Should be close to foundation pier around slurry outlet nozzle 3 and the exhaust nozzle, install firmly.
Requirement to filler 7 is: rapid hardening, high-strength reaches 30MPa 10 to 24 hours compressive strength; Super from the fluidised form simple filler, the overcurrent discrepancy in elevation is less than 4 centimetres; Do not have and shrink, aggregate size is easily peeled off less than 1 millimeter, microdilatancy, and vertical degree of free swelling maximum 0.5 ‰, operable time was greater than 40 minutes.
