Description
Technical field
The present invention relates to a kind of roadbed side slope skeleton construction technology and molds.
Background technique
Skeleton slope protection refers in highway, Railway Bed Slope, uses concrete or the frame-type structure of mortar flag stone formation
Object is built, grass planting protection, collapses to prevent roadbed side slope from slipping, be the component part of roadbed, belong to the protection works of roadbed among frame.Mesh
Before, it is conventionally employed sizing punching block or wooden model pour at the scene the small prefabricated components of slope protection skeleton mode tended to standardization apply
Work, with the continuous development of science and technology, this kind of method manifests drawback: first, big using standardized construction investment ratio, mold is not
It can recycle；Second, work progress requires height to operator, manual operation is improper, it is easy to lead to voids and pits, truncation
Arrisdefect；Third, prefabricated components transport, installation waste are seriously；Fourth, being also easier to side slope caused by occurring because of heavy rain, flood after building up
The occurrence of slope surfaces damaged or destroyed by floods such as collapsing, roadbed side slope sliding.In production practice, it is accordingly arranged although unit in charge of construction actively takes
Raising construction quality is applied, but can still find small-sized structures breakage and roadbed damaged or destroyed by flood phenomenon in on-the-spot investigation, therefore be badly in need of
A kind of fruitful solution targetedly, new is implemented for it.
Summary of the invention
It is an object of the present invention to overcome Traditional foundations side slope skeleton small-sized prefabricated member installation process to waste, it is not inconsistent
The requirement of standardization construction, can not carry out concentration pre-casting management, and provides a kind of roadbed side slope skeleton being simple and efficient and apply
Work technique.
To achieve the above object, the present invention proposes a kind of roadbed side slope skeleton construction technology, it include the steps that be:
Step 1 carries out preparation of construction；According to standardized construction standard, standardized prefabricated skeleton component production field is established
Institute, to facilitate side slope to carry out concentration pre-casting, storage and calling with prefabricated skeleton component；
Step 2, mold manufacture；Using the plastic mould of 3D printer printing side slope prefabricated skeleton component, and control mould
Has dimensional accuracy in ± 0.05mm；
Step 3, concrete mixing；According to design requirement, mixer centralized mixing is used in prefabricated skeleton component Workplace,
During mixing, material of marching into the arena is detected at any time, it is ensured that material qualification and stay in grade；Before concrete stirring, raw material are carried out
Water content detection, it is ensured that the accuracy of match ratio data inspects the slump by random samples in concrete whipping process at any time, guarantees that it can be filled
Divide stirring；
Step 4, concrete enter mould；The mold of the prefabricated components printed is placed on a vibration table, and according to design requirement pair
In a mold whether placement steel mesh is accepted or rejected, and the hopper by temporarily storing concrete is directed at mold and carries out discharging, discharging
When should once fill, there is not allowed that discontinuously add phenomenon, to avoid the subsequent addition of concrete part because of time of vibration deficiency, out
Existing bubble and voids and pits；
Step 5, concrete vibration；It is using shake table that the vibratory concrete in mold is uniform after the completion of entering mould to concrete；
Step 6 receives face, transport；Vibration terminates, after mold is transported to maintenance area together with the concrete structure of its inside together, point
Class is stored and putty knife is used to carry out receipts face, guarantees concrete surfacing；
Step 7, prefabricated components demoulding；Using salad oil as release agent；Using being manually demolded, when demoulding, guarantees coagulation
Soil is vacantly not more than 5cm away from ground level；After demoulding, after cleaning to mold, release agent is smeared again, repeats step 4 extremely
Step 7 carries out concrete structure prefabricated；
Step 8, concrete curing；Concrete structure prefabricated components after demoulding are covered using geotextiles, and to prefabricated components
Sprinkling maintenance is responsible for by special messenger；It is required that covering curing is not less than 7 days；
Step 9 carries out visual examination and sampling observation to prefabricated components；After prefabricated components demoulding to the appearance of each component into
Row checks that prefabricated components appearance requirement lines are straight, surfacing, no honeycomb, pitted skin, arrisdefect；To reaching 28 days intensity and set
It carries out spot-check and breaking inspection, detection intensity, size and internal reinforcing bar situation in respect of the prefabricated components of reinforcing bar；Detect underproof batch
It is destroyed；
Step 10 is packaged, piles up, builds database；The finished product prefabricated components for having reached some strength and qualification are beaten
Packet processing, to save space and convenient transportation；Prefabricated components separate stacking by model, type；In real-time update finished product database
Data record；
Step 11, finished product show, train；To reach assembled standardization, construction personnel is shown in finished product show area
Model is assembled, and hands over installation key control point: including installing, preceding opposite side slope surface examination, groove depth, line style is straight, does not design seam
It is smooth with platform drop-over that the prefabricated components of position will carry out jointing, the prefabricated components that bear down on one；
Step 12, transport, installation；In-site installation construction is filled out with roadbed, the construction speed of excavation construction side is synchronous, live slope
After face is checked and accepted, and scene is verified using rangefinder, in conjunction with the data model of the mold of 3D printing, accurately calculates slope surface
Area and prefabricated components quantity carry out application transport number to prefabricated skeleton component Workplace to prefabricated components actually required
Amount, Workplace personnel carry out outbound and record and updated in the database by microcomputer, will be transported with fork truck to the packing at scene
Prefabricated components carry out classification and discharge, and avoid breaking breakage in prefabricated part hanging transportational process；It is carried out through slope construction troop
