S8, dismounting anti-collision wall template.
Preferably, anti-collision wall template adopts set shaped steel formwork, and this set shaped steel formwork is divided into inside and outside two panels, and each forms by angle steel and Plate Welding.
Preferably, crashproof template arranges the drip of multistage broken line composition, damage for the drip reduced because form removal causes.
Preferably, in step s 2, the ratio of diesel oil and release agent is adopted to be that the intermixture of 3:1 spreads upon anti-collision wall template surface.
Preferably, the shrinkage joint place between adjacent anti-collision wall adopts steel plate to be connected with anti-collision wall template, and clogs polystyrene foam plate, and steel plate and anti-collision wall template connecting surface are coated with elastic sealing paste.
Preferably, in step S7, the concrete adopted comprises cement, water, composite material, sand, stone, and proportioning is 1:0.57:0.25:3:3.98.
Preferably, in the step s 7, control the concrete slump, be less than the concrete slump at more than ungulate position with the concrete slump meeting ungulate position, anti-collision wall bottom.
Preferably, in step S7, concrete adopts oblique layer method to advance and builds, and advances in skewed tunneling boring, and each segment length 2-4m, every layer thickness is no more than 30cm.
Compared to existing technology, beneficial effect of the present invention is:
The present invention by the inspection of reinforcing bar and make anti-collision wall template be adjusted to linear qualified, check template seal and shutoff space, so can effectively avoid producing a large amount of bubble to during anti-collision wall template concreting, honeycomb is avoided to produce, after making anti-collision wall form removal, nothing is damaged, overall lines are smooth and easy, meet code requirement, effectively meet the demands in outward appearance and structural strength to make anti-collision wall.
Accompanying drawing explanation
Fig. 1 is the flow chart of anti-collision wall construction method of the present invention.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the present invention is described further:
Anti-collision wall construction method as shown in Figure 1, comprises the following steps:
Whether S1, inspection anti-collision wall modular shuttering element be complete;
S2, to anti-collision wall template rust cleaning and coating release agent;
The reinforcing bar binding of S3, inspection anti-collision wall;
S4, surveying setting-out;
S5, anti-collision wall template reinforce anti-collision wall template is installed, anti-collision wall template is adjusted to linear qualified;
S6, check template seal shutoff space;
S7, build anti-collision wall concrete;
S8, dismounting anti-collision wall template.
By to the inspection of reinforcing bar and make anti-collision wall template be adjusted to linear qualified, check template seal and shutoff space, so can effectively avoid producing a large amount of bubble to during anti-collision wall template concreting, avoid honeycomb to produce, effectively meet the demands in outward appearance and structural strength to make anti-collision wall.Wherein, for the benefit of form the anti-collision wall surface of good smooth appearance, form topping to during the concreting of anti-collision wall surface, if topping is excessively thin, concrete surface can form obvious reinforcing bar iron mold; As topping is blocked up, concrete surface is just easy to crack.Need in the reinforcement fabrication installation process of therefore anti-collision wall template to carry out the control of reinforcement constitution sectional dimension and interim positioning work.Control thickness of protection tier, use plastic clip gasket ring to fill out every reinforcing bar, and do not adopt concrete pad, face contact is become point cantact, form removal back wall surface is left no trace.
Alternatively, anti-collision wall template adopts set shaped steel formwork, and this set shaped steel formwork is divided into inside and outside two panels, and each forms by angle steel and Plate Welding.When design typification steel form, the length of every sheet set shaped steel formwork and the spacing of each angle steel grid be considered.Because anti-collision wall template is less, seam is more, and flat appearance degree is poorer, and seam crossing surface is not easily smooth, also easily occurs spillage phenomenon, therefore should adopt bulk set shaped steel formwork; Owing to adopting artificial mounting or dismounting, template should meet rigidity requirement, again lightly more.Adopt through practice: the length of every block set shaped steel formwork is 1250mm, plate face is 4mm steel plate, and template periphery housing adopts L60x4 angle steel, to increase the rigidity of set shaped steel formwork edge especially lower edges, floor is that 4mm is thick, 50mm height band steel, and spacing is about 250mmx250mm.
According to rectangle drip, very easily damage the concrete at drip place when form removal, therefore, this example arranges the drip of multistage broken line composition in crashproof template, damages for the drip reduced because form removal causes.
Alternatively, in step s 2, adopt the ratio of diesel oil and release agent to be that the intermixture of 3:1 spreads upon anti-collision wall template surface, more easily leave no trace to make form removal back wall surface.
Alternatively, shrinkage joint place between adjacent anti-collision wall adopts steel plate to be connected with anti-collision wall template, and clogs polystyrene foam plate, and steel plate and anti-collision wall template connecting surface are coated with elastic sealing paste, so can ensure better anti-collision wall shaping after flat appearance degree.
The anti-collision wall concrete of this example is C30 ready mix concrete, and for ensureing that surface color is consistent, clear-water concrete does not adopt flyash.But due to narrow in anti-collision wall bottom width, the reinforcement placement of its inside is closeer, be unfavorable for getting rid of bubble during fluid concrete construction.So requirement need be improved to concrete workability, the quality of workability depends on design of concrete, and so, the concrete that this example adopts comprises cement, water, composite material, sand, stone, proportioning is 1:0.57:0.25:3:3.98, and concrete can be made to possess good workability.
For guaranteeing that concrete possesses good workability further, the basis increasing cement consumption adopting the sand coarse aggregate ratio of 43% reduce and carrying out water/binder ratio, gas in concrete is overflowed smoothly.Further, in the step s 7, control concrete concrete slump, be less than the concrete slump at more than ungulate position with the slump meeting ungulate position, anti-collision wall template bottom.Ungulate position, bottom adopts little slump concrete, to prevent too many bubble formation, and then is attached to hoof front side surface, prevents thin pulp from spilling simultaneously.More than hoof adopt high slump concrete, ooze closely knit under being beneficial to part mortar, and fill up surface blemishes.
Alternatively, the concrete of this example adopts oblique layer method to advance and builds, and advances in skewed tunneling boring, and each segment length 2-4m, every layer thickness is no more than 30cm.Utilize the gradient that concrete surface is formed, make anti-collision wall bottom concrete slurry amount relatively dense, to reduce the possibility producing honeycomb inside foundation, when being poured into variable cross-section place, should strengthening vibrating, guaranteeing that bubble is discharged.Anti-collision wall top concrete is tentatively received after water, carries out wiping one's face press polish, and wiping one's face with inner formword is that benchmark guarantees end face level, owing to receiving water, local occurs that depression person can mend slurry in time.Slurry face is crossed thick one and is added appropriate stone and compacting, can guarantee that end face is smooth-going and reduce anti-collision wall top crackle.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the claims in the present invention.
