Description
Technical Field
The utility model relates to a green cement blanket and escape canal structure. Is suitable for the technical field of water conservancy and hydropower engineering.
Background
In the process of developing and constructing dam projects, in order to ensure that no water is accumulated in the field during construction and to protect the excavated slope and exposed surface from surface runoff, temporary drainage ditches are often required to be arranged at the bottom of the dam and in low-lying areas to intensively drain rainfall runoff in the field to the outside of the field. Therefore, the construction of temporary drainage ditches is one of the common measures in the dam construction process.
However, the conventional temporary drainage ditch generally adopts direct trenching drainage or conventional brick drainage, and the brick body is also required to be subjected to waterproof mortar plastering and other processes, so that labor cost and material cost of adjacent construction engineering are greatly increased, the temporary drainage ditch is not environment-friendly, and the construction period is long. In sand and soil areas with strong water permeability, the built general temporary drainage ditch cannot meet the requirements of site construction, and the drainage ditch is easy to seep water to cause loose soil, collapse and the like. Therefore, an efficient technical scheme is urgently needed to solve the technical problems of time and labor waste, environmental pollution, water seepage and the like of the temporary drainage ditch, and therefore, the design of the green and environment-friendly cement blanket is very necessary.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: to the problem that exists, provide a green cement blanket and escape canal structure to solve technical problem such as current escape canal waste time and energy, not environmental protection and infiltration.
The utility model adopts the technical proposal that: a green environmental protection cement blanket which is characterized in that: the cement blanket is internally provided with a plurality of transverse fiber layers which divide the interior of the cement blanket into a plurality of layers of spaces, concrete materials are filled in the spaces, and a plurality of longitudinal capillary fiber tubes which can convey moisture for the concrete materials are arranged in the cement blanket.
The upper end of the longitudinal capillary fiber pipe is exposed out of the top surface of the cement blanket, and the lower end of the longitudinal capillary fiber pipe extends to the lowest layer space in the cement blanket.
The concrete material comprises a traditional concrete material filled in the lower space of the cement blanket and a green concrete material filled in the upper space of the cement blanket.
The utility model provides a drainage ditch structure which characterized in that: the green environment-friendly cement blanket is laid on the basis of the drainage ditch, concrete materials in the green environment-friendly cement blanket are watered and hardened, and the drainage ditch is constructed on the green environment-friendly cement blanket.
The utility model has the advantages that: the utility model has simple structure and convenient construction, the concrete material in the cement blanket is not hardened initially, and the cement blanket can be rolled up due to the flexibility of the fiber, thereby being convenient for transportation and storage; when the drainage ditch is used, the cement blanket is laid in a corresponding area, a hardened cement blanket with good seepage-proofing effect can be obtained after watering, and the drainage ditch is arranged on the hardened cement blanket, so that the technical problems that the existing drainage ditch wastes time and labor, is high in investment, and seeps water under high-permeability geological conditions are solved.

Detailed Description
The embodiment provides a green environmental protection cement blanket, be equipped with a plurality of layers of horizontal fibrous layer in this cement blanket, this a plurality of horizontal fibrous layer divide into a plurality of layers of spaces with cement blanket inside, fill in the space concrete material (including the traditional concrete material who fills in cement blanket lower part space and the green concrete material who fills in cement blanket upper portion space), be equipped with a plurality of vertical capillary fiber tubes that can carry moisture for concrete material in the cement blanket, vertical capillary fiber tube upper end exposes in cement blanket top surface, vertical capillary fiber tube lower extreme extends to the lowermost floor space in the cement blanket.
The transverse fiber layer is used for ensuring the stability of the filling material in the cement blanket and preventing the filling material from moving up and down; the longitudinal capillary fiber tubes are used for ensuring the stability of the internal filling materials and avoiding the transverse movement of the internal filling materials, and the longitudinal capillary fiber tubes and the transverse fiber layers form a criss-cross structure, so that the concrete materials of each part can be stably fixed.
In addition, the longitudinal capillary fiber tubes can effectively enable the internal concrete materials to be subjected to hydration reaction with water, provide nutrients required by vegetation growth for the green concrete materials in the later period and provide conditions for the plant growth by the residual soil after the temporary drainage ditch is abandoned. In the embodiment, the longitudinal capillary fiber tubes are not in a penetrating form, so that the water-resisting property of the cement blanket is not influenced.
In the embodiment, the traditional concrete material can play a role in seepage prevention after being hardened in water, and is filled at the bottom of the green concrete material, so that the concrete material can be isolated from water during the construction period and is used for temporary drainage projects such as drainage ditches and the like; the green concrete material has the functions of water and air permeability and providing a green vegetation growing environment, is filled on the upper part of the cement blanket, and can provide water, air and the like required for the growth of vegetation after construction. The embodiment combines the two, makes the cement blanket have both advantages, both can play the effect of prevention of seepage, can provide the growth of vegetation again after the construction period finishes, plays the environmental protection effect, practices thrift manpower and materials.
This embodiment still provides a escape canal structure, has the green cement blanket of laying on the escape canal basis, and this green cement blanket has the escape canal through the sclerosis of watering, and the green cement blanket of being under construction on the green cement blanket, and the green cement blanket after utilizing the sclerosis plays the prevention of seepage effect.
In the embodiment, after the cement blanket is laid, in the watering hardening process, the longitudinal capillary fiber tubes transmit water to the concrete material in the traditional cement blanket so as to ensure that the concrete material can be fully hydrated, reacted and hardened; in the later abandoning stage, the longitudinal capillary fiber tubes can convey nutrients such as moisture, air and the like required by vegetation growth to green concrete materials, so that the nutrients are necessary for vegetation to fully obtain growth, the water-resisting and water-draining effects are achieved when the vegetation-growing device is used, and the vegetation-growing environment can be provided when the vegetation-growing device is abandoned.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art can change, add or replace the above examples within the scope of the present invention.
