Abstract
The invention relates to grouting construction. A construction method of starching a base plate, comprises a base plate with a certain length and width and comprises the following steps of: excavating and starching; supporting formworks; grouting; measuring elevation; compacting; and demounting formworks and maintenance. The starching method has simple method, convenient operation and high mounting precision for starching the base plate, simplifies the mounting process, reduces the working load of mounting and shortens the mounting construction period greatly.
Description
Technical field
The present invention relates to grouting construction, relate in particular to the backing plate grout construction method.
Background technology
The requirement of stability in the plant equipment installation process, so its base all adopts cement to build to form usually, the used grouting material of present grouting method needs outsourcing, and is transported to the job site, and construction cost is higher.Need at the construction field (site) grouting is expected to stir, what what stir with, go back GPRS proportioning and mixing time simultaneously, it is more loaded down with trivial details to construct, and installation accuracy is poor, and the workload of installation is big and long with installation period.
Summary of the invention
The present invention is intended to solve the above-mentioned defective of existing grouting method, and a kind of seat slurry plastic sheet construction method is provided.Seat paste-making method of the present invention is simple, easy to operate, and seat slurry plastic sheet installation accuracy height has been simplified erection procedure, has reduced the workload of installing; Installation period shortens significantly.
The present invention is achieved in that
A kind of seat slurry plastic sheet construction method includes the backing plate of certain length and width, and it comprises the following steps:
Dig seat slurry hole step:
Dig out seat slurry hole at the concrete foundation position that backing plate is set;
Prop up the template step:
After seat slurry cross-cut chisel became, water dashed or blows down foreign material in the hole with compressed air, and wetting, eliminated ponding, greasy dirt in the hole then;
Grouting step:
Be coated with the thin cement paste of one deck in the seat slurry hole of digging out, do template with checkered steel plate, pour in the hole with the strong concrete that is about to stir, answer layering to make firm by ramming during placing, every layer thickness is preferably the 40-50 millimeter, smashes continuously to slurry float gage layer; Grouting performs one group of concrete test block simultaneously, test three days compressive strength up to three days compressive strength greater than 40MPa;
Measure the absolute altitude step:
Concrete surface after bleeding or the disappearance of water mark, is not placed backing plate and is also measured absolute altitude.Backing plate is positioned over and uses hand on the concrete, knocks the backing plate face with hand hammer chock plate, makes its steady decline,
Make real step:
The backing plate absolute altitude makes real the backing plate circumferential concrete after measuring, and makes it firm.Concrete surface layer should be lower than backing plate face 2-5 millimeter, checks the backing plate absolute altitude before the concrete initial set once more.
Tear open and touch the maintenance step:
Cover straw bag, the moistening beginning maintenance of watering must not collide and vibrate between curing time, and striking time should be carried out after maintenance begins 24 hours, continued maintenance 48 hours after the form removal.
Described seat slurry plastic sheet construction method, in the step of described cutting seat slurry hole, the length in described seat slurry hole is than the long 60-80 millimeter of backing plate, and width should be than the wide 40-60 millimeter of backing plate, and the degree of depth that digs into surface of base is greater than 30 millimeters.
Described seat slurry plastic sheet construction method, the cement paste water/binder ratio in the described grouting step is: cement 0.5Kg, water 1-1.2Kg.
Described seat slurry plastic sheet construction method, the template thickness in the described grouting step are 5-8mm.
Described seat slurry plastic sheet construction method, in the described grouting step, high low arc all around in the middle of concrete surface layer is shaped as.
Described seat slurry plastic sheet construction method, the weight proportion of cement, yellow sand, stone and the water of the seat slurry high-strength concrete in the described grouting step is 1:1:1:0.36.
Seat slurry plastic sheet construction method of the present invention has been realized the stability in the equipment installation process, has simplified construction sequence, has significantly reduced installation workload.The present invention is adapted to heavy mechanical equipment and installs, and has simplified erection procedure, and is easy and simple to handle, simple.The seat slurry is simple, easy to operate, backing plate installation accuracy height; The present invention has effectively reduced the workload of installing; Improved installation rate; Installation period contracts significantly., not only at metallurgy industry, other relates to heavy mechanical equipment, and the industry that electric fixtures is installed all can be used, and good application prospects is arranged.
The specific embodiment
Adopt a preferred embodiment of the present invention to further specify the present invention below:
The present invention is for the stability in the plant equipment installation process, improves the requirement of equipment installment quality and installation rate and develops, and carries out according to the following step:
(1) digs out seat slurry hole at the concrete foundation position that backing plate is set, the length in seat slurry hole should be than the long 60-80 millimeter of backing plate, width should be than the wide 40-60 millimeter of backing plate, seat slurry cross-cut chisel is gone into the degree of depth of surface of base must not be less than 30 millimeters, and seat slurry floor height reinforced concrete thickness must not be less than 50 millimeters, use the concrete that exceeds a grade of base concrete label to carry out during the seat slurry.
The seat slurry plastic sheet embedding precision
| Sequence number | Content | Unit | Precision |
| 1 | The absolute altitude franchise | mm | +0～0.5 |
| 2 | Levelness | mm/m | 0.10 |
Seat slurry high-strength concrete match ratio
| Cement | Sand | Stone | Water | Remarks |
| 1 | 1 | 1 | 0.36 | Weight ratio |
(2) after seat slurry cross-cut chisel became, water dashed or blows down odd job in the hole with compressed air, and wetting 30 minutes, eliminate ponding in the hole then, must not speckle with greasy dirt in the hole.Be coated with the thin cement paste of one deck in the hole, in order to bond between fresh and hardened concretes, the cement paste water/binder ratio is: cement 0.5Kg, water 1-1.2Kg.Checkered steel plate with thickness δ=6mm is done template, pours in the hole with the strong concrete that is about to stir, and answers layering to make firm by ramming during placing, and every layer thickness is preferably the 40-50 millimeter, smashes continuously to starching the float gage layer in order to clapping slurry.High low arc all around in the middle of the concrete surface layer shape is answered, exhaust air during in order to the placement backing plate.Perform one group of concrete test block simultaneously, test three days compressive strength.Compressive strength should be greater than 40MPa in three days.
(3) when concrete surface not after bleeding or water mark disappear, can place backing plate and measure absolute altitude.Backing plate surface absolute altitude limit deviation is ± 0.5 millimeter, and backing plate is positioned over and uses hand on the concrete, knocks the backing plate face with hand hammer chock plate, makes its steady decline, must not tiltedly hit when knocking, in order to avoid air is scurried between backing plate and the concrete surface.The backing plate absolute altitude makes real the backing plate circumferential concrete after measuring, and makes it firm.Concrete surface layer should be lower than backing plate face 2-5 millimeter, checks the backing plate absolute altitude before the concrete initial set once more.And cover the straw bag moist curing three days (72 hours) that waters.Must not collide and vibrate between curing time.
Striking time should be carried out after 24 hours, continued maintenance after the form removal.
