Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and more particularly to an aqueduct. Background Art

[0002] An aqueduct is a key part of a water conservancy project, mainly used to convey water flow across natural or artificial obstacles such as rivers, valleys, and highways, and plays a crucial role in aspects such as irrigation, water supply, flood control, and water diversion. Traditional aqueducts mostly adopt reinforced concrete beam aqueducts. Although they have sufficient strength and bearing capacity, there are many deficiencies in practical applications. First, although the cost of reinforced concrete aqueducts is relatively low, their structures and self-weights are huge, they have high requirements for the bearing capacity of the foundation, and the construction period is long, which cannot meet the requirements of rapid and intelligent construction. Second, reinforced concrete is prone to diseases such as corrosion and cracks, resulting in poor structural durability of the aqueduct, and maintenance and reinforcement are required during the operation period.

[0003] In view of the above problems, it is urgent to develop lighter, more durable, and more economical aqueduct materials and structures to meet the needs of water diversion and drainage. In recent years, with the development of new material technologies, glass fiber reinforced plastic (GFRP) sand-filled pipes have attracted attention due to their light weight, high strength, corrosion resistance, etc., and have been widely used in fields such as water supply and drainage. GFRP sand-filled pipes are used in the drainage part of the aqueduct, and their ultra-long durability has unique advantages. When used in cooperation with the support structure of a truss aqueduct, it has the advantages of not being restricted by the site, flexible structural layout, rapid and convenient construction, and can solve the shortcomings of traditional aqueducts.

[0004] The present utility model precisely aims at the deficiencies of the prior art and proposes an assembled GFRP sand-filled pipe aqueduct, aiming to overcome the limitations of existing aqueducts in terms of structural stability, durability, and economy. The GFRP sand-filled pipe aqueduct of the present utility model adopts a truss structure support column and a support protection component, providing a solution with a simple structure, rapid construction, corrosion resistance, and long service life, which can be applied to cross various terrains and obstacles, improving the safety and durability of the aqueduct, and at the same time saving materials and human resources. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present utility model is to provide an assembled GFRP sand-filled pipe aqueduct, which is composed of a GFRP sand-filled pipe aqueduct, a truss aqueduct support column, and a support protection component, and has the advantages of stable structure, durable materials, rapid construction, and high cost-effectiveness.

[0006] The technical solution of the present utility model to solve the above technical problems is: an assembled fiberglass sand-filled pipe aqueduct, comprising a fiberglass sand-filled pipe aqueduct, a truss-type aqueduct support column and a support and protection assembly. The aqueduct body includes a plurality of fiberglass sand-filled pipe sections connected in sequence. A water passage is formed inside the aqueduct body. The aqueduct body is placed on the support and protection assembly, and the support and protection assembly is welded to the truss-type aqueduct support column.

[0007] The aqueduct body is composed of multiple fiberglass sand-filled pipe sections connected together. The two ends are respectively a water inlet and a water outlet. The multiple fiberglass sand-filled pipes are connected by socket connection. Two built-in "O"-shaped rubber seals are used to ensure the sealing performance of the connection, forming a closed water flow channel. Anti-ultraviolet and anti-aging additives are added to the inner and outer surface materials of the aqueduct body to resist the degradation of material properties that may be caused by long-term exposure to sunlight. The water inlet and the water outlet are located at both ends of the fiberglass sand-filled pipe and are composed of fiberglass sand-filled pipes. The water inlet adopts a U-shaped pipe design to introduce the channel water at the water source into the fiberglass sand-filled pipe. A flow guiding structure is provided inside the water outlet pipe to ensure smooth discharge of water flow.

[0008] The truss-type aqueduct support column is composed of a truss structure and a truss steel column. The truss structure is composed of an upper chord, a lower chord, a vertical rod and a web member. Each member is connected through a gusset plate to form a solid truss structure, which improves the stiffness and load-bearing capacity of the overall structure. The upper chord, the lower chord and the web member are made of steel to bear the main bending moment, pressure and shear force. The steel needs to be treated against corrosion to ensure its durability. The gusset plate is fixed to the member by welding, which is convenient for quick installation and disassembly and adapts to the flexibility of on-site construction.

[0009] The truss steel column is composed of a foundation connecting member, a steel column and an anti-seismic block. The foundation connecting member connects the steel column to the concrete pile cap, and bolt connection is adopted to transfer the load to the foundation. The steel column is connected to the truss base by welding. Anti-seismic blocks are arranged on both sides of the truss to prevent the lateral movement of the truss-type aqueduct support column.

[0010] The support and protection assembly includes two arc-shaped protection plates and two square steel plates. The two arc-shaped protection plates are placed front and back and are connected to the square steel plates by welding, and soft contact rubber blocks are provided to protect the pipe sections. There are specific-shaped hollow parts in the middle of the arc-shaped protection plates, and the spacing is the same as the socket interface size of the fiberglass sand-filled pipe to accommodate the socket interface of the fiberglass sand-filled pipe and provide a stable support for the fiberglass sand-filled pipe.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The utility model uses a glass fiber reinforced plastic sand-filled pipe as the material of the aqueduct body and a truss as the support structure. Compared with traditional aqueducts, it has a lower density and higher strength, thus reducing the self-weight of the entire structure and the requirements for the support structure; the glass fiber reinforced plastic sand-filled pipe has excellent corrosion resistance and can resist chemical corrosion and the erosion of seawater, sewage, etc., extending the service life of the aqueduct and reducing the maintenance cost; the columns of the truss structure provide greater flexural and torsional stiffness, enhancing the stability of the aqueduct under various loads; the entire structure is assembled for construction, with a faster construction speed and shorter construction period.

[0019] In the truss aqueduct support column, it includes two parts: the truss steel column and the truss structure. The truss steel column is composed of a concrete cap 1, a steel column 2, a truss base 3, bolts 4 and seismic blocks 5. The concrete cap 1 is placed on the ground and is symmetric about the central axis of the overall aqueduct. The steel column 2 is connected to the concrete cap 1 through bolts 4 and then connected to the truss base 3 by welding. The seismic block 5 is also connected to the truss base 3 by welding.

[0020] The aqueduct support column is designed with a truss structure and is composed of multiple triangular units formed by vertical bars 11, upper chord bars 12, lower chord bars 14 and web bars 13, and is placed on the truss steel column.

[0021] In the aqueduct body, it includes a glass fiber reinforced plastic sand-filled pipe 6, a pipe support 7, a support and protection assembly 8, a water inlet 9 and a water outlet 10. The pipe support 7 is designed with a groove matching the end shape of the glass fiber reinforced plastic sand-filled pipe, so that the glass fiber reinforced plastic sand-filled pipe 6 can be accurately inserted and fixed in the pipe support. An O-ring seal is equipped at the connection to ensure the sealing performance of the connection, prevent water leakage and ensure the operation efficiency of the aqueduct. The water inlet 9 is arranged at one end of the aqueduct and is designed with a U-shaped pipe, which matches the end shape of the glass fiber reinforced plastic sand-filled pipe 6 to ensure the smooth transition of water flow and reduce the head loss. The structural design of the water inlet 9 enables it to effectively introduce the channel water at the water source into the glass fiber reinforced plastic sand-filled pipe. The water outlet 10 is located at the other end of the aqueduct and is designed with a diversion structure to ensure the smooth discharge of water flow.

[0022] The support and protection assembly includes a set of supporting structures. These supporting structures are located above the base and are mainly composed of two square steel plates 11 and two arc-shaped protection plates 12, which are used to support the weight of the glass fiber reinforced plastic sand-filled pipe and bear the pressure brought by the water flow. The arc-shaped protection plates 12 are designed to be placed front and back, with a hollow part of a certain size in the middle. This hollow part allows the pipe support 7 of the aqueduct to pass through, so as to achieve precise positioning. The square steel plates 11 are placed left and right to connect the two arc-shaped protection plates 12 in the front and back to form a stable support structure.

[0023] The utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the utility model, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the utility model.
