Abstract
The invention discloses a concrete curing method for a pipe buried in a structure, which is characterized in that a grouting pipe is buried in a concrete structure, a water receiving port is arranged on the concrete structure, and curing water enters the grouting pipe through the water receiving port, so that the concrete structure is cured. The invention adds the new use of the grouting pipe for maintenance, and solves the problem that the space of the structure which is not easy to carry out conventional maintenance operation is limited in the early stage of maintenance and the maintenance is difficult to implement.
Description
Technical Field
The invention relates to a concrete curing method, in particular to a concrete curing method for a buried pipe in a structure, and belongs to the technical field of concrete curing.
Background
In concrete structure construction, curing is an important process for ensuring the performance such as concrete strength and durability and reducing the occurrence of quality defects such as cracks in construction, but depending on the working space and the working progress, when curing is most needed 7 days before the concrete structure is finally set, curing may not be performed due to the reason that the working space is narrow, the support structure cannot be removed, and the like.
The concrete wall panel has the advantages that the concrete wall panel is particularly obvious in the situation of underground passages, comprehensive pipe galleries and other structures under town roads, and particularly, the wall panel is difficult to maintain in place, so that cracks are generated on the wall panel, concrete cannot reach corresponding strength, durability is reduced, and other quality defects are caused.
A new maintenance process is developed, a good concrete structure maintenance effect can be achieved under a limited condition, and the performance of the concrete structure is improved.
Disclosure of Invention
The invention aims to provide a concrete curing method for pipe burying in a structure, which is suitable for concrete structures with limited operation space, in particular to concrete structures such as pipe galleries, box culverts, underground passages and the like with multiple wallboard structures and small space.
The technical scheme adopted by the invention for solving the technical problem is as follows:
a concrete curing method for a pipe buried in a structure is characterized in that a grouting pipe is buried in a concrete structure, a water receiving opening is formed in the concrete structure, and curing water enters the grouting pipe through the water receiving opening, so that the concrete structure is cured.
The further scheme is as follows:
when the concrete structure is wallboard concrete structure, the slip casting pipe is located wallboard concrete structure upper end surface region to set up the water receiving mouth in concrete structure upper end, maintenance water gets into the slip casting pipe through the water receiving mouth, and oozes from the wallboard upper end through the slip casting pipe, flows down along the wallboard surface, realizes the maintenance of wallboard.
The further scheme is as follows:
when the concrete structure is the non-wallboard concrete structure, the grouting pipe is positioned inside the concrete structure, the water receiving port is arranged on the concrete structure, the curing water directly permeates into the structure through the grouting pipe, the structure is cured, and the purpose of comprehensive curing is achieved.
The further scheme is as follows:
the grouting pipe penetrates through the upper end of the whole wallboard concrete structure.
The further scheme is as follows:
the grouting pipe is buried in the surface of the wallboard concrete structure and fixed on the surface of the template through a fixture, or fixed on the steel bar net through a fixture.
The further scheme is as follows:
the grouting pipe is close to the opposite pull rod area, and a water flow control baffle is installed in the opposite pull rod area.
The invention adds the new use of the grouting pipe for maintenance, and solves the problem that the space of the structure which is not easy to carry out conventional maintenance operation is limited in the early stage of maintenance and the maintenance is difficult to implement.

Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
A concrete curing method for a pipe buried in a structure is characterized in that a grouting pipe 2 is buried in a concrete structure, the grouting pipe 2 is located in the surface area of the upper end of a concrete structure of a wallboard, a water receiving opening is formed in the upper end of the concrete structure, a water inlet pipe and a valve 1 are mounted on the water receiving opening, curing water enters the grouting pipe through the water receiving opening, seeps out of the upper end of the wallboard through the grouting pipe, and flows down along the surface of the wallboard, so that the curing of the wallboard is realized.
To bulky concrete, slip casting pipe 2 is located inside the concrete structure, is provided with the water receiving mouth on the concrete structure, inside maintenance water passes through the direct infiltration structure of slip casting pipe, carries out the maintenance to the structure inside, reaches the purpose of comprehensive maintenance.
The grouting pipe penetrates through the upper end of the whole wallboard concrete structure.
The grouting pipe is buried in the surface of the wallboard concrete structure and fixed on the surface of the template through a fixture, or fixed on the steel bar net through a fixture.
The grouting pipe 2 is close to a template counter-pull rod 3 in a counter-pull rod area, and a water flow control baffle 4 is installed in the counter-pull rod area.
During specific implementation, the grouting pipes with proper pipe diameters are selected according to the structural form and the pressure of the access water, the lengths of the grouting pipes are segmented, and the grouting pipes are manufactured according to a design scheme.
When the wall roof steel bar formwork is constructed, the grouting pipes are installed and maintained, the grouting pipes are buried in the surface of the wall plate structure, the grouting pipes can be fixed to the surface of the formwork through the fixtures, the grouting pipes can also be fixed to the steel bar net through the fixtures, and the fixture intervals guarantee that the grouting pipes cannot deform due to impact when concrete is poured. The grouting pipe is suitable to be close to the opposite pull rod area, so that the baffle is convenient to mount to control excessive water seepage.
And continuing the structural construction according to the normal concrete structure construction sequence until the structural concrete is poured.
Concrete placement accomplishes 24 hours, carries out constant voltage water injection to in the slip casting pipe, loosens reinforcing measures such as wallboard template reinforcing bolt simultaneously, and the template is pried loose, and the maintenance water of being convenient for is oozed. And then construction is carried out according to a normal construction procedure.
Regular inspection is carried out during water injection maintenance, flow is adjusted according to the seepage condition of the wallboard maintenance water, the baffle is installed, maintenance requirements are guaranteed, and meanwhile maintenance water consumption is controlled.
Although the present invention has been described herein with reference to the illustrated embodiments thereof, which are intended to be preferred embodiments of the present invention, it is to be understood that the invention is not limited thereto, and that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure.
