Abstract
The present invention is a kind of method of back-grouting in Equipment Foundations work progress, the specific steps are：The exterior sheathing of Equipment Foundations is installed to the top mark eminence of back-grouting；The mounting of roof plate PVC linea angulatas of exterior sheathing；The grouting height required according to construction drawing is stayed on the inside of Equipment Foundations sets groove as Equipment Foundations grout groove；Mass concrete water storing conservation is carried out using Equipment Foundations grout groove；Curing age carries out form removal, dabbing processing later；Equipment installation is corrected and is checked and accepted；After equipment installation acceptance(check), Equipment Foundations grout groove is cleared up, back-grouting is carried out and fills and leads up to designed elevation.The present invention reduces secondary grouting template installation procedures, improve appearance technique；It improves work efficiency, when foundation construction reduces process, and back-grouting directly carries out in Equipment Foundations grout groove, reduces the branch die process of back-grouting, and back-grouting operation can be carried out by being cleaned out after equipment is in place, and the time is saved for equipment installation.
Description
Technical field
The present invention relates to power construction Equipment Foundations back-grouting technical field of construction more particularly to a kind of Equipment Foundations to apply
The method of back-grouting during work.
Background technology
In electric power construction projects construction, Equipment Foundations need back-grouting mostly, and Normal practice is：First Equipment Foundations are applied
Work after equipment installs centering in place, then is cleaned, formwork to grout blanket bottom absolute altitude, then carries out back-grouting.It is such to do
Method process is numerous and diverse, and gene basis concrete is different from back-grouting material material, concrete base layer and grout blanket color after the completion of construction
It is inconsistent, and there is construction joint trace to be difficult to handle, unsightly, model sheetinstallat fixation difficulty is big, time-consuming, cost for appearance technique
It is higher, it is difficult to ensure that appearance processing quality.
Invention content
Present invention seek to address that the deficiencies in the prior art, and a kind of side of back-grouting in Equipment Foundations work progress is provided
Method.
The present invention to achieve the above object, using following technical scheme：
A kind of method of back-grouting in Equipment Foundations work progress, the specific steps are：
A, construction drawing is checked comprehensively before constructing, it is ensured that construction drawing does not have mistake；
When b, requiring to construct to Equipment Foundations according to construction drawing, the exterior sheathing of Equipment Foundations is installed to back-grouting
Top mark eminence；
C, the mounting of roof plate PVC linea angulatas of exterior sheathing；
D, the grouting height required according to construction drawing is stayed on the inside of Equipment Foundations sets groove as Equipment Foundations grout groove,
The depth of Equipment Foundations grout groove is lower 30-50mm than design height, and for dabbing, the outer wall thickness of Equipment Foundations grout groove is
100mm；
E, mass concrete water storing conservation is carried out using Equipment Foundations grout groove；
F, curing age carries out form removal, dabbing processing later；
G, equipment installation is corrected and is checked and accepted；
H, after equipment installation acceptance(check), Equipment Foundations grout groove is cleared up, back-grouting is carried out and fills and leads up to design
Absolute altitude.
The exposed parts of Equipment Foundations exterior sheathing use Shimizu concrete template.
The size of PVC linea angulatas is 30mm × 30mm.
The beneficial effects of the invention are as follows：The present invention reduces secondary grouting template installation procedure, set during non-winter construction
In standby foundation grouting slot can water storage huge foundation surface is conserved；It solves concrete base layer with grout blanket color to differ
The problem of cause, reduces construction joint, and improves appearance technique；It improves work efficiency, when foundation construction reduces process, secondary
Grouting directly carries out in Equipment Foundations grout groove, reduces the branch die process of back-grouting, is cleaned out just after equipment is in place
Back-grouting operation can be carried out, the time is saved for equipment installation.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
In figure：1- Equipment Foundations grout grooves；2-PVC linea angulatas；3- Equipment Foundations；4- Shimizu concrete templates；
It is described in detail below with reference to the embodiment of the present invention with reference to attached drawing.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Figure 1, in a kind of Equipment Foundations work progress back-grouting method, the specific steps are：
A, construction drawing is checked comprehensively before constructing, it is ensured that construction drawing does not have mistake；
When b, requiring to construct to Equipment Foundations 3 according to construction drawing, the exterior sheathing of Equipment Foundations 3 is installed to back-grouting
Top mark eminence；
C, the mounting of roof plate PVC linea angulatas 2 of exterior sheathing；
D, it is stayed according to the grouting height of construction drawing requirement in 3 inside of Equipment Foundations and sets groove as Equipment Foundations grout groove
1, the depth of Equipment Foundations grout groove 1 is lower 30-50mm than design height, for dabbing, the outer wall thickness of Equipment Foundations grout groove 1
For 100mm；
E, mass concrete water storing conservation is carried out using Equipment Foundations grout groove 1；
F, curing age carries out form removal, dabbing processing later；
G, equipment installation is corrected and is checked and accepted；
H, after equipment installation acceptance(check), Equipment Foundations grout groove 1 is cleared up, back-grouting is carried out and fills and leads up to design
Absolute altitude.
The exposed parts of 3 exterior sheathing of Equipment Foundations use Shimizu concrete template 4.
The size of PVC linea angulatas 2 is 30mm × 30mm.
The present invention reduces secondary grouting template installation procedure, can be stored in Equipment Foundations grout groove 1 during non-winter construction
Water conserves 3 surface of Equipment Foundations；It solves the problems, such as that concrete base layer and grout blanket color are inconsistent, reduces construction
Seam, and improve appearance technique；It improves work efficiency, Equipment Foundations 3 reduce process when constructing, and back-grouting is directly being set
It is carried out in standby foundation grouting slot 1, reduces the branch die process of back-grouting, secondary filling can be carried out by being cleaned out after equipment is in place
Operation is starched, the time is saved for equipment installation.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as employ the inventive concept and technical scheme of the present invention progress various improvement or not improved direct application
In other occasions, within protection scope of the present invention.
