Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology for escalators, and in particular to an outdoor escalator shaft structure for pedestrian bridges. Background Technology

[0002] With the continuous development of urban transportation, pedestrian bridges, as an important facility to ensure the safety of pedestrians crossing the street, are receiving increasing attention for their function and comfort. In some pedestrian bridges with high traffic volume and significant elevation differences, outdoor escalators are often installed to facilitate pedestrian passage.

[0003] However, the existing outdoor escalator shaft structure of pedestrian bridges has some problems: on the one hand, due to the large weight of the escalator itself, coupled with the load of people on the escalator, the bridge abutment where the escalator is located is prone to settlement, affecting the normal operation and safety of the escalator; on the other hand, there is a lot of rain in the outdoor environment, and the existing shaft structure has poor drainage performance, which easily leads to water accumulation. Water accumulation not only affects the service life of the escalator, but may also pose a safety hazard to pedestrians, while increasing maintenance costs.

[0004] Therefore, there is a need for an outdoor escalator shaft structure for pedestrian bridges that can effectively solve the problems of easy settlement and water accumulation. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a pedestrian bridge outdoor escalator shaft structure that improves structural stability and enhances drainage capacity.

[0006] To achieve this objective, the present invention adopts the following technical solution: This utility model provides an outdoor escalator shaft structure for a pedestrian bridge, including a bridge abutment body. A pile foundation is installed at the bottom of the bridge abutment body. An escalator is installed on the bridge abutment body. An escalator shaft bottom slab is provided on one side of the bridge abutment body. An escalator shaft side wall is provided on the top of the side of the escalator shaft bottom slab away from the bridge abutment body. The bridge abutment body, the escalator shaft bottom slab, and the escalator shaft side wall are integrally cast to form an escalator shaft structure. An HDPE pipe is pre-embedded at the bottom of the escalator shaft structure. A water collection well is connected to the end of the HDPE pipe away from the escalator shaft structure. A drainage pipe is connected to the bottom of the water collection well and is connected to the municipal drainage system. A stainless steel grating cover is installed on the water collection well.

[0007] The preferred technical solution of this utility model is that a groove is reserved on the bridge abutment, a pre-embedded steel plate is provided on the groove, and the escalator is placed on the pre-embedded steel plate.

[0008] The preferred technical solution of this utility model is that the bridge abutment body is arranged in a stepped shape, and the bridge abutment body is provided with pre-embedded steel bars, which are located at the bottom of the pre-embedded steel plate.

[0010] A preferred embodiment of this invention is that a submersible sewage pump is installed in the water collection well, and the submersible sewage pump is automatically controlled by the liquid level.

[0011] The preferred technical solution of this utility model is that the diameter of the HDPE pipe is 150mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model utilizes the high vertical bearing capacity of pile foundations to effectively transfer the load of escalators and pedestrians, reducing abutment settlement and ensuring the normal operation and safety of escalators. The method of integrally casting the abutment body with the escalator shaft bottom slab and side walls enhances the integrity and stability of the shaft structure and extends its service life. By pre-embedding HDPE pipes, installing water collection wells, and installing submersible sewage pumps, a complete drainage system is formed, which can quickly and effectively drain rainwater, avoiding water accumulation, reducing maintenance costs, and ensuring pedestrian safety.

Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] An outdoor escalator shaft structure for a pedestrian bridge includes a bridge abutment body 1, with pile foundations 2 installed at the bottom of the abutment body 1, an escalator 3 installed on the abutment body 1, an escalator shaft bottom plate 4 on one side of the abutment body 1, and an escalator shaft side wall 5 on the top of the side of the escalator shaft bottom plate 4 away from the abutment body 1. The abutment body 1, the escalator shaft bottom plate 4, and the escalator shaft side wall 5 are integrally cast to form an escalator shaft structure. An HDPE pipe 6 with a diameter of 150mm is pre-embedded at the bottom of the escalator shaft structure. A water collection well 7 is connected to the end of the HDPE pipe 6 away from the escalator shaft structure. A drainage pipe 71 is connected to the bottom of the water collection well 7 and is connected to the municipal drainage system. A stainless steel grating cover 8 is installed on the water collection well 7.

[0017] By setting pile foundation 2, a solid foundation support is provided for the entire structure, which improves the overall stability of the structure. The bridge abutment body 1, the bottom plate of the escalator well 4, and the side wall of the escalator well 5 are cast together to form the escalator well structure, which enhances the integrity and deformation resistance of the structure and can effectively resist the influence of external loads and natural environment. HDPE pipe 6 is pre-embedded at the bottom of the escalator well structure and connected to the municipal drainage system through water collection well 7 and drainage pipe (71), forming a complete drainage channel. It can quickly and effectively drain rainwater and other liquids in the escalator well, avoid rainwater accumulation and damage to the automatic escalator 3, ensure the normal operation of the automatic escalator 3, extend its service life, and effectively solve the problems of easy settlement and water accumulation of the existing outdoor automatic escalator 3 of the pedestrian bridge.

[0018] As a possible implementation of this solution, preferably, a slot is reserved on the bridge abutment body 1, and a pre-embedded steel plate 11 is provided on the slot, and the escalator 3 is placed on the pre-embedded steel plate 11.

[0019] A slot is reserved on the bridge abutment body 1 and a pre-embedded steel plate 11 is installed to provide a flat and solid installation foundation for the escalator 3. The escalator 3 is placed on the pre-embedded steel plate 11, which makes the force on the escalator 3 more uniform, reduces the phenomenon of local stress concentration, and avoids the escalator 3 shaking or being damaged due to unstable installation during operation, thereby improving the stability and safety of the escalator 3 installation.

[0020] As a possible implementation of this solution, preferably, the bridge abutment body 1 is arranged in a stepped shape, and the bridge abutment body 1 is provided with pre-embedded steel bars 12, which are located at the bottom of the pre-embedded steel plate 11.

[0021] The abutment body 1 is set in a stepped shape, which not only better adapts to the installation requirements of the escalator 3, but also increases the contact area between the abutment body 1 and the foundation, thereby improving the stability of the abutment body 1. The embedded steel bars 12 are set inside the abutment body 1 at the bottom of the embedded steel plate 11, which further enhances the structural strength and load-bearing capacity of the embedded steel plate 11. It can effectively bear the weight of the escalator 3 and the load generated during operation, ensuring that the structure is not easily damaged during long-term use and improving the durability of the entire structure.

[0022] As a possible implementation of this solution, preferably, it also includes a C25 plain concrete cushion layer 9, which is respectively set at the bottom of the bridge abutment body 1, the bottom plate of the escalator well 4 and the bottom of the water collection well 7, and has a thickness of 10cm.

[0023] The C25 plain concrete subbase 9 serves a leveling function, ensuring the construction quality of the superstructure. It also provides some water resistance, reducing groundwater erosion of the superstructure. Furthermore, the C25 plain concrete subbase 9 can evenly transfer the load of the superstructure to the foundation, improving the foundation's bearing capacity and stability, thereby ensuring the safety and reliability of the entire shaft structure.

[0024] As a possible implementation of this solution, preferably, a submersible sewage pump is installed in the water collection well 7. This submersible sewage pump employs automatic level control, enabling automated drainage of the water collection well 7 without manual operation, thus saving labor costs. When the water level in the water collection well 7 reaches a set height, a level sensor sends a signal to control the submersible sewage pump to automatically start drainage, preventing rainwater from overflowing the water collection well 7 and affecting escalator operation due to untimely drainage. When the water level drops to a set position, the level sensor sends a signal to control the submersible sewage pump to automatically stop, saving energy and improving the operating efficiency and reliability of the drainage system.
