Technical Field
The utility model relates to a nodular cast iron pipe bending section installation construction structure, and belongs to the technical field of construction structures.
Background
In water supply and distribution pipelines of municipal, water conservancy, industrial and agricultural irrigation systems, circulating water pipelines of power plants, various pressure and non-pressure pipelines, as well as inverted siphons, liner pipes for pressure tunnels and high-soil-covering lower culvert pipes, nodular cast iron pipes are frequently used because the nodular cast iron pipes have the characteristics of thin pipe walls, light weight, good elasticity, good corrosion resistance, long service life, no harm to human bodies and the like.
When the nodular cast iron pipes are laid in a construction environment with a plurality of horizontal and vertical inflection points, the technology adopted at present is to butt joint two nodular cast iron pipes by using standard anchor elbows (for example, the Chinese patent publication No. CN113202974A is a butt joint method for segmental construction of the long-distance nodular cast iron pipes).
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a nodular cast iron pipe bending section installation construction structure.
The utility model is realized by the following technical scheme.
The utility model provides a nodular cast iron pipe bending section installation construction structure, which comprises:
a first ductile cast iron pipe;
the second nodular cast iron pipe is in socket joint communication with the first nodular cast iron pipe;
the first nodular cast iron pipe is fixedly communicated with a bending section, and the straight end of the second nodular cast iron pipe is inserted into the bending section, so that the second nodular cast iron pipe is communicated with the first nodular cast iron pipe in a socket mode.
And the first nodular cast iron pipe is welded and fixed with the bending section.
The first nodular cast iron pipe and the bending section are integrally formed and fixed.
The first nodular cast iron pipe is formed by a nodular cast iron pipe with the diameter of 1.8 m.
The second nodular cast iron pipe is formed by a nodular cast iron pipe with the diameter of 1.8 m.
The outer part of the bending section is arc-shaped, and the outer part of the arc-shaped bending section is connected with the circular outer arc line of the first nodular cast iron pipe.
The inner diameter of the bending section is the same as that of the fixed end of the first nodular cast iron pipe.
The bending section and the socket joint communication end of the second nodular cast iron pipe are conical.
The utility model has the beneficial effects that: because the second nodular cast-iron pipe is in socket joint communication with the bending section fixed on the first nodular cast-iron pipe, the socket joint communication between the second nodular cast-iron pipe and the first nodular cast-iron pipe is directly realized, the construction amount of the project is reduced, the construction efficiency is improved, and the problems that the buttress is required to be built by using the anchor block elbow, the construction amount of the project is increased, and the construction efficiency is reduced are solved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1-a first nodular cast iron pipe; 2-a second nodular cast iron pipe; 11-curved section.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1.
The utility model relates to a ductile cast iron pipe bending section installation construction structure, which comprises:
a first nodular cast iron pipe 1 formed by nodular cast iron pipes with the diameter of 1.8m is adopted;
the second nodular cast iron pipe 2 is in socket joint communication with the first nodular cast iron pipe 1, the second nodular cast iron pipe 2 is formed by a nodular cast iron pipe with the diameter of 1.8m, the nodular cast iron pipe 1 generally adopts a nodular cast iron pipe with the diameter of 1.5m, and the nodular cast iron pipe 1 is changed into a large-diameter nodular cast iron pipe by adopting the diameter of 1.8 m;
when the first nodular cast iron pipe 1 is produced in a production plant, the first nodular cast iron pipe 1 is fixedly communicated with the bending section 11 in a welding or integrated mode, and the straight end of the second nodular cast iron pipe 2 is inserted into the bending section 11, so that the insertion communication between the second nodular cast iron pipe 2 and the first nodular cast iron pipe 1 is realized.
Because the second nodular cast-iron pipe 2 is in socket joint communication with the bending section 11 fixed on the first nodular cast-iron pipe 1, the socket joint communication between the second nodular cast-iron pipe 2 and the first nodular cast-iron pipe 1 is directly realized, the construction amount of the project is reduced, the construction efficiency is improved, and the problems that the buttress is required to be built when the anchor block elbow is used, the construction amount of the project is increased, and the construction efficiency is reduced are solved.
The outer portion of the bending section 11 is arc-shaped, and the outer portion of the arc-shaped bending section 11 is connected with the circular outer arc line of the first nodular cast iron pipe 1, so that water chestnuts or edges are avoided.
The inner diameter of the bending section 11 is the same as that of the fixed end of the first nodular cast iron pipe 1, and fluid flows more smoothly between the bending section 11 and the first nodular cast iron pipe 1.
The bent section 11 and the second nodular cast iron pipe 2 socket joint communication end are conical, so that the second nodular cast iron pipe 2 can be conveniently in socket joint communication.
Foretell nodular cast-iron pipe bending section installation construction structures uses in Chongqing city Yuxi water resource configuration engineering, and the pipeline level along the line and vertical inflection point of this engineering are numerous, and the installation degree of difficulty is great, adopts foretell nodular cast-iron pipe bending section installation construction structures of this application, can reduce the use quantity of buttress, improves the efficiency of construction for the construction progress has reduced the construction degree of difficulty.
