Description
Technical field
The utility model relates to civil engineering, in particular to a kind of pregrouting for mending concrete structural cracks is miniature
Plastic tube.
Background technique
Concrete is the construction material that current usage amount is maximum, boundary of works area is most wide, and raw material is easy to get, intensity is higher, can
Plasticity is good, its main feature is that compression strength is high, tensile strength is low, tensile strength generally only has the 10% of its compression strength, and tough
Property it is poor, can temperature stress caused by the heat of hydration during contraction distortion, especially casting of concrete in mass when hardening process
It can make concrete cracking.
In order to solve the shortcomings of concrete, engineer tries that fibrous material is added when concrete mixes and stirs, and utilizes fibre
The advantages that high intensity of dimension, high tenacity, the performances such as toughness, cracking resistance, the shock resistance of concrete are improved, it is mixed to thus form fiber
Solidifying soil.The more fiber concrete of domestic application is based on steel fiber reinforced concrete at present, part mix carbon fiber, glass fibre,
The high molecular materials such as polypropylene fibre.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of pregroutings for mending concrete structural cracks
Micro plastic pipe improves the cracking resistance of concrete structure to realize the voluntarily repairing of distress in concrete.
It is as follows that the utility model solves technical solution used by its technical problem:
A kind of pregrouting micro plastic pipe for mending concrete structural cracks of the utility model, it is characterized in that: packet
The micro plastic pipe in concrete is mixed and stirred when including casting concrete structure, the tensile strength of micro plastic tube material is lower than coagulation
Native tensile strength, micro plastic pipe middle section are hollow and thin-walled structure, the internal filling crack repairing slurries of perfusion in advance；It is described miniature
Longitudinal both ends of plastic tube are heat seal section.
Longitudinally spaced setting holding force tenon in the heat seal section.
The utility model has the beneficial effects that micro plastic pipe is mixed and stirred in casting concrete structure in wherein, in coagulation
In soil structure maintenance, manufacture and service process, once the tensile stress of concrete structure reaches the tensile strength of micro plastic pipe, then
Hollow and thin-walled structure is pulled off, and the crack repairing slurries inside sealed up for safekeeping fill outflow to surrounding concrete crack, is realized
The voluntarily repairing of distress in concrete, greatly improves the cracking resistance of concrete structure.

Component and corresponding label be shown in figure: concrete structure 10, crack 11, micro plastic pipe 20, holding force tenon 21,
Crack repairing slurries 30.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to FIG. 1, FIG. 2 and FIG. 3, the miniature modeling of a kind of pregrouting for mending concrete structural cracks of the utility model
Expects pipe, including mixing and stirring the micro plastic pipe 20 in concrete when casting concrete structure, the material of micro plastic pipe 20 resists
Tensile strength is lower than concrete tensile strength, and micro plastic pipe middle section is hollow and thin-walled structure, and the internal filling of perfusion in advance crack is repaired
Mend slurries 30.Longitudinal both ends of the micro plastic pipe 20 are heat seal section.In the maintenance of concrete structure 10, molding and use
In the process, once the tensile stress of concrete structure 10 reaches its tensile strength of 20 hollow and thin-walled structure of micro plastic pipe, then in
Empty thin-wall construction is pulled off, and the crack repairing slurries 30 inside sealed up for safekeeping fill outflow to crack 11 around, realizes coagulation
The voluntarily repairing of soil cracking seam 11, greatly improves the cracking resistance of concrete structure.
Referring to Fig. 4, Fig. 5 and Fig. 6, micro plastic pipe 20 is lower than the macromolecule material of concrete tensile strength using tensile strength
Material production.One end elder generation heat seal of micro plastic pipe 20 is closed, the perfusion filling crack repairing slurry into the hollow and thin-walled structure in middle section
Reheating closes the closing other end after liquid 30.It is longitudinally spaced in the heat seal section to break hollow and thin-walled structure in time
Holding force tenon 21 is set.
The utility model a kind of pregrouting for mending concrete structural cracks described above that only explains through diagrams is micro-
Some principles of shape plastic pipe are not intended to shown in being confined to the utility model and described specific structure and the scope of application
It is interior, therefore all corresponding modifications that may be utilized and equivalent, belong to the applied the scope of the patents of the utility model.
