It is widely used in construction due to its advantages such as no vibration, no soil squeezing, low noise, and suitability for use in densely built urban areas. Depending on the drilling process, bored piles can be divided into bored piles drilled with dry operations, bored piles drilled with mud wall protection, and bored piles drilled with manual excavation. A pouring device is required for pouring during the construction of bored piles.

[0035] As a technical optimization solution of the utility model, by providing an elastic anti-lost rope 14, when the user moves the magnetic strip 8 downward to the bottom, the user can use the resilience of the elastic anti-lost rope 14 to quickly pull the magnetic strip 8 back to its original position, and the elastic anti-lost rope 14 can be used to connect the magnetic strip 8 to the concrete mixing tank 1, thereby avoiding the loss of the magnetic strip 8.

[0036] The working principle and use process of the utility model are as follows: when the user needs to know the remaining amount of concrete in the current concrete mixing tank 1, the user can directly understand the remaining amount of concrete in the current concrete mixing tank 1 through the observation window 4. In the process of using the observation window 4, if part of the concrete in the concrete mixing tank 1 is attached to the left side of the observation window 4, the user can hold the magnetic strip 8 and adsorb it to the corresponding iron strip 5 across the observation window 4, and then drag the magnetic strip 8 up and down to drive the iron strip 5 to move up and down, and then the iron strip 5 will drive the scraping strip 6 to scrape off the concrete attached to the left side of the observation window 4, so that the observation effect of the observation window 4 is clearer, and when the iron strip 5 moves up and down During the movement, the limit sleeve 71 will be driven to move synchronously, and then the limit sleeve 71 will slide with the limit rod 72 to limit the iron bar 5 in the front, back, left and right directions, so as to prevent the iron bar 5 from deviating during the up and down movement, thereby improving the transmission stability of the iron bar 5. When the scraper bar 6 ages after long-term use, the user can directly hold the pull ring 93 and pull it outward, and then the pull ring 93 will drive the scraper bar 6 to be pulled outward, and then the scraper bar 6 will drive the corresponding connector 91 to be pulled out of the plug-in slot 92, and then the connector 91 on the new scraper bar 6 is plugged into the corresponding plug-in slot 92, so that the new scraper bar 6 can be quickly installed, which has the ability to assist in observing the remaining internal usage.

[0037] In summary, the bored pile concrete pouring device for road and bridge construction is provided with an observation window 4. When the user needs to know the remaining amount of concrete in the current concrete mixing tank 1, the user can directly understand the remaining amount of concrete in the current concrete mixing tank 1 through the observation window 4, thereby solving the problem that there is a lack of auxiliary observation structure on the mixing tank, which causes the user to be unable to observe the remaining amount of concrete in the current mixing tank during the process of using the mixing tank to mix and pour concrete, and thus cannot add concrete in time.
