Description

Technical Field

[0001] The utility model relates to the technical field of pipe bridge connection, in particular to a pipeline and concrete support base connection structure of a pipe bridge across a river. Background Art

[0002] With the construction and development of cities, the urban pipeline network is becoming more and more dense, and the number of pipelines erected across water systems, canyons and other obstacles using bridge structures is increasing year by year. The stable connection between the pipeline and the bridge cap beam foundation is the basis for the pipeline to provide stable services. The larger the span of the pipeline bridge, the higher the reliability requirements for the connection design.

[0003] Chinese patent CN215172789U discloses a pipe bridge fixing device suitable for municipal pipelines. The technical solution of the utility model is: a pipe bridge fixing device suitable for municipal pipelines, used to fix the pipeline on the pipe piles on both sides of the river bank, characterized in that: there are two fixed clamps for fixing the pipeline on the top of the same pipe pile, and an energy absorption mechanism arranged between the two fixed clamps; the energy absorption mechanism has a spring sleeved on the pipeline, and the two ends of the spring are respectively connected to the annular gaskets sleeved on the pipeline. The fixed clamp has a steel pipe support and a steel clamp that cooperates with the steel pipe support to fix the pipeline, wherein the steel pipe support is fixed to the top of the pipe pile through embedded parts, and the top of the steel pipe support is formed with an arc groove that matches the pipeline. Rubber pads are padded between the steel pipe support and the steel clamp and the pipeline. The utility model is suitable for the field of municipal pipelines.

[0004] However, the steel skeleton of this technical solution will cause corrosion after long-term use, especially in an environment with moisture and corrosive media, where it is prone to rust, making the steel skeleton more prone to deformation and insufficient stability, which in turn leads to reduced performance or failure of the steel skeleton, causing the pipe bridge to loosen and other problems. The fixing effect is not good, and maintenance operations such as rust removal, zinc or coating are generally required. This process is time-consuming and labor-intensive, inconvenient to use, and there is no protective structure on the outside of the pipeline, which is easily damaged by humans. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies in the prior art and provide a pipeline and concrete support foundation connection structure for a river crossing pipe bridge, which fixes the pipeline on a post-cast base formed by concrete casting by a clamp, and combines anti-climbing thorns on the outer periphery of the pipeline to achieve a more stable and firm function of the pipeline, solving the problem of loose pipelines caused by structural instability of the steel skeleton after long-term use.

[0027] Example

[0028] like Figure 1-4As shown, this embodiment provides a pipeline and concrete support foundation connection structure of a river-crossing pipe bridge, including: a base 1 cast with concrete and a post-cast base 2 arranged on the base 1 for installing a pipe 3, the outer peripheral sleeve of the pipe 3 is installed on the post-cast base 2 through a clamp 4, the outer peripheral sleeve of the pipe 3 is provided with a clamp 4, the post-cast base 2 and the base 1 are both cast by concrete, because concrete has the characteristics of high compressive strength, good durability, and a wide range of strength grades, and its raw materials are abundant, the price is low, the production process is simple, the use cost is low, and it will not cause corrosion after long-term use, so that the concrete structure is more stable, and then the pipe 3 is more stable, the fixing effect is good, and no maintenance operations such as rust removal, zinc or coating are required, which saves a lot of manpower and material resources, is easy to use, and reduces the difficulty of maintenance and repair. The clamp 4 prevents the pipe 3 from shaking easily, thereby ensuring the stability of the overall structure.

[0029] Among them, the post-cast base 2 is concave, which is adapted to the shape of the pipe 3, that is, the pipe 3 is adapted and installed on the post-cast base 2, which increases the stability of the pipe 3, and the pipe 3 is generally preferably a hollow cylindrical shape, and the post-cast base 2 is correspondingly preferably a concave semicircular shape, which is easy to install.

[0030] At the same time, a fastener 21 is pre-embedded on the post-cast base 2. The fastener 21 vertically penetrates the post-cast base 2 completely and extends into the base 1, and the end of the fastener 21 is laterally bent, so that the connection between the post-cast base 2 and the base 1 is more secure and the structure is more stable. The fastener 21 is preferably a bolt, which has a simple structure, is easy to disassemble and assemble, and has a good fixing effect.

[0031] In this embodiment, the fastener 21 is adapted and installed with the fixed end 41 of the clamp 4, so that the structure among the pipe 3, the clamp 4 and the post-cast base 2 is more compact and the stability is enhanced, and the pipe 3 will not easily become loose or vibrate, and the number of fasteners 21 is preferably four, so that the strength of the clamp 4 can stabilize the pipe 3.

[0032] In this embodiment, a rubber pad 22 is arranged between the fixed end 41 and the post-cast base 2, and an isolation cushion layer 32 is arranged between the clamp 4, the post-cast base 2 and the pipe 3. The isolation cushion layer 32 and the rubber pad 22 can both isolate and absorb shock, that is, reduce the vibration amplitude of the pipe 3, further enhance the stability of the pipe 3 and make it work more smoothly, and can also avoid wear of the clamp 4, the pipe 3 and the post-cast base 2 respectively, thereby extending their service life.

[0033] In this embodiment, a plurality of anti-climbing spikes 31 are provided on the periphery of the clamp 4, and the extension lines of the bottom ends of the anti-climbing spikes 31 all pass through the center of the clamp 4 and diffuse outward in a radial distribution, that is, the anti-climbing spikes 31 cover the entire clamp 4, so that the clamp 4 will not be damaged, ensuring that the clamp 4 can be always fixed on the pipe 3, making the pipe 3 more stable as a whole, and the anti-climbing spikes 31 can effectively prevent people from climbing the pipe 3, so that the pipe 3 will not be easily damaged, thereby extending the service life of the pipe 3.

[0034] Of course, premixed concrete is in a flow plastic state for a certain period of time. After being poured into a mold and compacted and solidified, it can be made into structures or components of various shapes and sizes. After forming, cement and water undergo hydration reaction for a period of time to harden the concrete. The hardened concrete has the properties of general stone, and then the base 1 and the post-cast base 2 are formed. Therefore, concrete is also called concrete, which means artificial stone.

[0035] In addition, the post-cast base 2 is generally cast with C25 fine stone concrete. Fine stone concrete generally refers to concrete with a maximum particle size of coarse aggregate not exceeding 15 mm. Fine stone concrete shall not use pozzolanic cement. Sand shall use medium-coarse sand with a particle size of 0.3 to 0.5 mm. The mud content of coarse aggregate shall not be greater than 1%, and the mud content of fine aggregate shall not be greater than 2%. Tap water or drinkable natural water shall be used as water.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
