However, when the piers are located at the bottom of deep V-shaped canyons in mountainous areas, the steep terrain makes the construction of temporary access roads a large-scale project with high construction difficulty, high cost and high safety risks. Moreover, the construction of temporary access roads will damage the ecological environment. Utility Model Content

This construction structure can realize the construction of ultra-high piers in mountainous deep V-shaped canyon environments. It achieves rapid and uniform delivery of large volumes of concrete over ultra-long and ultra-high distances by using a "three-level" relay method of chute plus mixer, ground pump plus pump pipe and hydraulic placing machine. According to the pier construction height, the ground pump is transferred from the lower platform to the upper platform to solve the problem of insufficient pumping pressure when delivering ultra-high concrete.
[0004] To achieve the aforementioned technical features, the purpose of this utility model is as follows: A general construction structure for ultra-high piers without access roads in a deep V-shaped canyon includes a mountaintop site located at the top of the hillside, a fully enclosed chute arranged along the steep cliff slope, the outlet of the fully enclosed chute being located directly above a storage hopper, the outlet of the storage hopper being connected to a mixer, the mixer being connected to a pump pipe via a ground pump, and the end of the pump pipe being connected to a hydraulic concrete placing machine located at the top of the pier; a steel trestle bridge is set in the middle of the steep cliff slope, the steel trestle bridge being connected to the pier via a connecting steel platform; and a tower crane is fixed at the upper part of the steep cliff slope.
[0005] Preferably, the hilltop platform is used for the movement of cement mixer trucks.
[0006] Preferably, the inlet end of the fully enclosed chute is located at the hilltop site and can be connected to the unloading port of the mixer truck.

Detailed Implementation
[0025] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0026] See Figure 1-6 A general construction structure for ultra-high piers without access roads in a deep V-shaped canyon includes a mountaintop site 2 located at the top of the hillside, a fully enclosed chute 4 arranged along the steep cliff slope 17, the outlet of the fully enclosed chute 4 being located directly above a storage hopper 7, the outlet of the storage hopper 7 being connected to a mixer 8, the mixer 8 being connected to a pump pipe 10 via a ground pump 9, the end of the pump pipe 10 being connected to a hydraulic concrete placing machine 11 located at the top of the pier 13; a steel trestle bridge 5 being set in the middle of the steep cliff slope 17, the steel trestle bridge 5 being connected to the pier 13 via a connecting steel platform 16; and a tower crane 14 being fixed at the upper part of the steep cliff slope 17. When the ultra-high bridge piers are located at the bottom of deep V-shaped canyons in mountainous areas, there is no need to build access roads for construction. A "three-level" relay method of chute and mixer, ground pump and pump pipe and hydraulic placing machine is used to achieve rapid and uniform delivery of large volumes of concrete over ultra-long and ultra-high distances. Depending on the construction height of the pier, the ground pump is transferred from the lower platform to the upper platform to solve the problem of insufficient pumping pressure when delivering ultra-high concrete. The construction is safe and efficient.
[0027] Furthermore, the hilltop platform 2 is used for the movement of the mixer truck 1. The hilltop platform 2 facilitates the subsequent movement of the mixer truck 1.
[0028] Furthermore, the inlet end of the fully enclosed chute 4 is located at the hilltop site 2 and can connect with the discharge port of the mixer truck 1. The fully enclosed chute 4 facilitates the transport of concrete, thereby facilitating the transfer of concrete from the mixer truck 1 to the subsequent storage hopper 7.
[0029] Furthermore, the storage hopper 7 is fixedly installed on top of the bottom working platform 6 or the steel trestle bridge 5, with the bottom working platform 6 located at the bottom of the steep cliff slope 17. The bottom working platform 6 facilitates concrete transport during the construction of the ultra-high piers when their height is relatively low. The steel trestle bridge 5 facilitates concrete transport during the construction of the ultra-high piers when their height reaches a higher stage.
[0030] Furthermore, a vertical lift 12 is simultaneously installed on the outer wall of the pier 13. The vertical lift 12 facilitates the subsequent construction process, allowing workers to climb onto the pier 13 and thus enabling the construction of the pier 13.
[0031] Furthermore, a pedestrian walkway 3 is constructed along the steep cliff slope 17 for personnel passage and material transport. The aforementioned pedestrian walkway 3 facilitates the transportation of materials and equipment during subsequent construction.
[0032] Furthermore, a slant lift 15 is installed between the steel trestle bridge 5 and the bottom working platform 6. The slant lift 15 facilitates the transportation of materials during subsequent construction.
[0033] Furthermore, the storage hopper 7, mixer 8, and ground pump 9 are arranged sequentially on top of the bottom working platform 6 and the steel trestle bridge 5, following the construction height of the pier 13. This flexible arrangement allows for the completion of the entire construction process of the pier 13.
[0034] The specific working process and principle of this utility model are as follows: A general construction method for ultra-high bridge piers located at the bottom of a deep V-shaped canyon. During the initial construction phase of the ultra-high piers, concrete is transported to the hilltop site 2 using a mixer truck 1. The mixer truck 1 is aligned with a fully enclosed chute 4. To prevent impact during the downward transport of concrete from a height and to facilitate control of the concrete transport speed, a storage hopper 7 is installed on the bottom working platform 6. Concrete is transported from the hilltop site 2 to the storage hopper 7 on the bottom working platform 6 via the fully enclosed chute 4. To prevent segregation of the concrete during long-distance transport, concrete is released from the storage hopper 7. After being mixed twice by mixer 8, the soil is fed into ground pump 9. The concrete in ground pump 9 is transported through pump pipe 10 to the hydraulic placing boom 11 set on top of the pier 13. The hydraulic placing boom 11 distributes the concrete evenly and symmetrically into the pier 13. Workers enter the steel trestle bridge 5 in the middle of the hillside from the hilltop site 2 via the pedestrian walkway 3 built on the hillside. They are then transported by inclined elevator to the vertical elevator 12 set at the bottom of the pier 13 and enter the pier 13 site via the vertical elevator 12. After the materials and equipment are transported to the hilltop site 2, they are lifted to the construction site by tower crane 14.
[0035] The construction method for the ultra-high piers at the higher stage of construction is as follows: Concrete is transported to the hilltop site 2 using a mixer truck 1. To reduce the pumping height of the ground pump 9, ensure the quality of concrete pumping, and facilitate the movement of workers, a steel trestle bridge 5 is connected to the pier 13 via a connecting steel platform 16. Then, the storage hopper 7, mixer 8, and ground pump 9 are moved from the bottom working platform 6 to the steel trestle bridge 5. Concrete is transported from the hilltop site 2 to the storage hopper 7 on the steel trestle bridge 5 via a fully enclosed chute 4. The concrete discharged from the storage hopper 7 is then... After secondary mixing in mixer 8, the concrete is fed into ground pump 9. The concrete in ground pump 9 is transported through pump pipe 10 to hydraulic placing boom 11 set on top of pier 13. The hydraulic placing boom 11 distributes the concrete evenly and symmetrically. Workers enter the steel trestle bridge 5 in the middle of the hillside from the hilltop site 2 via the pedestrian walkway 3 built on the hillside, and then enter the vertical lift 12 via the connecting steel platform 16. The vertical lift 12 is then used to enter pier 13. After the materials and equipment are transported to the hilltop site 2, they are lifted to the construction site by tower crane 14.
