Description
Technical Field
The invention relates to the technical field of large-scale equipment dismantling, in particular to a construction method for large-scale equipment protective dismantling.
Background
Along with the industrial development, a large number of production processes are continuously reformed, equipment matched with each production line is also continuously updated, a large number of new production lines or technical transformation projects are driven, the new production lines or the technical transformation projects are often constructed on the original production lines, and the actual construction period progress of the whole project is directly influenced by how to quickly dismantle the original equipment.
Because the large-scale equipment bottom plate area is great, has very big adhesion between equipment and basic concrete or the grout surface course, at the in-process of conventional equipment installation simultaneously, in order to guarantee that equipment can not be pulled out or the phenomenon of displacement because of the atress in the production process, often design has reinforcing means such as shear key and rag bolt, and the shear key often sets up the central point of equipment bottom, even still can't remove the equipment under the condition of the shear key any more even use jack cooperation hoist.
At present, a foundation breaking and dismantling mode is often adopted to realize the dismantling of large equipment, the technical transformation of a production line requires the protective dismantling of the equipment, the conventional mechanical breaking vibration is large, the damage to the equipment and the foundation is large, the breaking efficiency of the artificial pneumatic pick is low, the labor intensity is high, the workers in partial areas are difficult to enter the operation, and the construction time is long.

Detailed Description
In order that the present invention may be better understood by those skilled in the art, it is further described below with reference to the accompanying drawings and examples. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. Embodiments of the invention and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, a construction method for protective dismantling of large equipment provided by an embodiment of the invention includes:
s1, positioning a dismantling line 11 on a foundation 10;
s2, cutting the foundation 10 along the dismantling line 11 by using the rope saw 12, and cutting off the anti-pulling structure 13 in the foundation 10;
and S3, after the foundation 10 is cut, the equipment 14 is lifted by a crane.
In step S1, before the demolition work, the demolition range may be determined according to the type of the equipment 14 and the form of the foundation 10. Because the foundation 10 is mostly a special-shaped mechanism, the structures of the devices 14 arranged on the foundation 10 are different, the dismantling construction range is determined according to the appearance, the installation form and the construction drawing of the devices 14 before construction, the position of the anti-pulling structure 13 is determined, and marking points are made, wherein the anti-pulling structure 13 at least comprises shear keys and foundation bolts; and then carrying out line drawing connection according to the determined marked points to form a closed dismantling line 11. Referring to fig. 2, the two-dot chain line in the drawing is a dismantling line 11 positioned on the foundation 10.
In step S2, see fig. 2, the rope saw 12 is installed and the cutting direction of the rope saw 12 is determined from the removal line 11. Since the removal line 11 is often not a single horizontal or vertical cutting line, it is necessary to use a guide pulley mounted on the foundation 10 by expansion bolts or directly on the floor of the apparatus 14 for guiding the adjustment of the rope saw chain in the cutting direction adjustment position. When the wire saw 12 is installed, the wire saw 12 is used to cut the foundation 10 along the removal line 11 and to sever the shear keys and anchor bolts or like pullout resistant structures 13 within the foundation 10 to separate the equipment 14 from the foundation 10.
Since the wire saw 12 is cut to work with water, a water drain work should be done during the cutting process. Because most of the anti-pulling structures 13 are metal structures, the abrasion condition of the rope saw chain should be checked at any time in the cutting process, and the rope saw chain should be replaced in time according to the abrasion condition. Meanwhile, the size, compactness and hardness of each part in the foundation 10 are different, whether the footage efficiency of the dismantling line 11 is consistent or not should be observed at any time in the cutting process, and the direction of the rope saw 12 should be adjusted in time. In the cutting process, when the cutting is carried out to the position of a certain guide pulley, the guide pulley at the position is removed in time, so that the normal operation of cutting work is ensured.
In step S3, after the cutting of the foundation 10 is completed, the device 14 and the foundation 10 form a separate structure at the cutting position, and the device 14 is lifted by a crane, so as to complete the protective dismantling of the device 14. Specifically, when the cutting of the foundation 10 is completed, the device 14 is first pre-loosened, and then the device 14 is lifted away by a crane. Referring to fig. 3, a method of pre-loosening a device 14 includes: a plurality of fixing plates 15 are fixed around the device 14; placing a jack 16 on the ground below the fixed plate 15; the fixing plate 15 is lifted upward by the jack 16. Illustratively, the securing plate 15 is welded to the base plate of the apparatus 14; because of the high weight of the apparatus 14, the fixing plate 15 is preferably made of a steel plate having a large thickness, for example, a steel plate having a thickness of 30 mm. Wherein, the jack 16 with proper number can be selected according to the structural shape and weight distribution of the equipment 14 before pre-loosening. By pre-loosening the device 14, the device 14 can be moved up a distance relative to the foundation 10, so that the device 14 is prevented from colliding with the foundation 10 during lifting of the device 14 by means of a crane.
According to the construction method for the protective dismantling of the large-scale equipment, provided by the embodiment of the invention, the pulling-resistant structure 13 in the foundation 10 is cut off by using the rope saw 12, the separation of the equipment 14 and the foundation 10 is completed under the condition that the equipment 14 is not damaged, the integrity of the equipment 14 can be effectively ensured, and the protective dismantling of the large-scale equipment is realized; the invention uses rope saw cutting to replace the traditional time and labor consuming procedures of manual pneumatic pick breaking, mechanical breaking and the like, so that the construction process is simpler, the manual consumption in the dismantling process is reduced, the construction period is shortened, and the dismantling efficiency is improved.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
