Description
Technical field
The present invention relates to highway engineering construction fields, more particularly to side slope cutting manually digging hole friction pile exposed face clear water
Formwork erecting structure and construction technology.
Background technique
Design often has the cutting of " wall between friction pile+stake " to protect in the cutting protection works of hills and mountain road,
When the cutting protection works are constructed, to ensure construction safety, the construction technology that artificial digging pile is used to friction pile is often needed to,
To pore-forming and steel reinforcement cage concrete perfusion pile is placed, and after pile body reaches design strength, then excavates the earthwork of road side,
To guarantee that the construction subsequent prefabricated board wall of friction pile can support cutting side soil pressure.The friction pile pavement of road above section
Front and two sides are exposed.Using conventional manual digging pile construction technique, corresponding measure, road to be excavated are not used
Behind side cubic metre of earth, the concrete of the front of road surface above section and two sides is since artificial digging pile formwork is coarse, appearance effect
Fruit will be very poor, and the acceptance requirement of clear-water concrete is not achieved, if carrying out plastering working process, also not meet " clear-water concrete
Application technology regulation " requirement.
Existing Shimizu concrete template uses grain board as template, and it is existing cicada seam faulting of slab ends, pitted skin, abrasive band etc. easily occur
As and the shortcomings that high production cost.
It is general to be realized using template surface smoothness is improved for these disadvantages, such as the method for customization steel form.It should
Method is will to customize steel form after the molding of ground integral assembling, is integrally transferred in friction pile stake holes with crane, is then poured
Antiskid pile concrete.The method solves the problems, such as sliding pile exposed face concrete appearance, but this side using the smoothness of steel form
There are certain limitations for method: on the one hand need to expand the aperture of friction pile borehole because customization steel form has certain thickness, cause expense
It is uneconomical with increase；On the other hand, it because customization steel form is cast in stake holes, can just be taken after road side cubic metre of earth need to be excavated
Steel form is used in turn out, and customization steel form is used in turn by larger limitation, and cost is larger.
Or in template plate face after the reinforcing materials such as brushing composite polymer material and glass fibre, so that it may make steel form
Pour apparent effect with steel frame plywood formwork promotion, however these methods for material and skills in the process of construction level requirement and its
Height, construction cost of implementation is also relatively high, and popularization and application are extremely restricted.
Summary of the invention
Technical problem to be solved by the invention is to provide side slope cutting manually digging hole friction pile exposed face clear water formwork knots
Structure and construction technology are constructed fairly simple using unique multilayered structure, are reached manually digging hole friction pile exposed face clear water coagulation
The native good purpose of apparent mass.
The technical solution adopted by the present invention to solve the technical problems is: it is exposed to provide side slope cutting manually digging hole friction pile
It is exposed in friction pile needs to return the setting of pea gravel concreten described in spray-up time spray-up including pea gravel concreten for face clear water formwork erecting structure
On the artificial digging pile stake holes inner sidewall of side, the surface that pea gravel concreten returns spray-up is provided with mortar and returns spray-up, the sand
Starching back on the inner sidewall of spray-up tiling has the thin template of plastics, is evenly distributed on the inner sidewall of the thin template of the plastics and antiskid
Several precast linings of stake reinforcing bar binding together.
As supplement, it is provided on artificial digging pile stake holes inner sidewall in horn-like hole stake shield small, lower mouth is big suitable for reading
Wall, the pea gravel concreten go back to the outside that spray-up is arranged in hole pile wall, and the most thin position of thickness is 25mm.
As supplement, the thin template thickness of the plastics is 5mm, and surface is smooth.
Preferably, size 50mm × 50mm × 25mm of the precast lining, using same pile concrete label
Subtract stone concrete production.
The construction technology of specific side slope cutting manually digging hole friction pile exposed face clear water formwork erecting structure, specific steps are such as
Under:
(a) pea gravel concreten is set first on the inside of the artificial digging pile stake holes that friction pile needs exposed side and returns spray-up,
It is preliminary it is levelling, look for it is vertical；
(b) spray-up surface spray furnace is returned in pea gravel concreten return spray-up, it is accurately levelling on vertical pea gravel concreten surface,
With template flatness, the subsequent thin template of plastics easy to support；
(c) the thin template of plastics is sequentially placed into stake holes, is fixed on mortar with microcephaly's steel nail from bottom to top and goes back to spray-up surface；
(d) friction pile reinforcing bar after overall binding, binds precast lining in artificial digging pile stake holes, guarantees concrete
Protective layer thickness；
(e) the last casting concrete in stake holes.
The utility model has the advantages that the present invention relates to side slope cutting manually digging hole friction pile exposed face clear water formwork erecting structure and construction works
Skill is constructed fairly simple using unique multilayered structure, is reached manually digging hole friction pile exposed face apparent mass of clear concrete
Good purpose.
