Description

Technical Field

[0001] The utility model relates to the field of municipal pipelines, in particular to a street lamp infrastructure capable of passing through underground pipelines. Background Art

[0002] With the development of my country's economy and science and technology, people's requirements for urban infrastructure are gradually increasing. As an important part of urban infrastructure and "smart city", the lighting system is an important part of the daily life of urban residents.

[0003] At present, the commonly used street lamp foundation in engineering is a regular cube, and the foundation structure is reinforced concrete. During construction, the template is set up according to the size requirements of the drawing. After the support is completed, the steel bars are installed and the embedded parts and threading pipes are buried. After the template, steel bars and embedded parts are installed, concrete is poured. In order to improve driving comfort and avoid setting pipeline manhole covers on the roadway, high-grade urban roads will set some pipelines and inspection wells on side strips or sidewalks. Side strips and sidewalks are often used as facility strips to lay various traffic poles and street lamps. In recent years, the "multi-pole integration" that has emerged has combined street lamps and traffic poles. This makes the street lamp foundation often conflict with underground pipelines. In the old road upgrading and reconstruction project, the complex underground pipelines make it impossible to place street lamps. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of conflict between the position of the street lamp foundation and the underground pipeline on the side of the road and the difficulty of spatial arrangement, and to provide a street lamp infrastructure that can pass through the underground pipeline. Under the premise of ensuring the safety of the street lamp foundation, the underground pipeline can be designed and constructed by passing through the lower part of the street lamp foundation.

[0005] The utility model adopts the following technical solution to solve the technical problem: a street lamp infrastructure capable of passing underground pipelines, comprising a street lamp foundation arranged on the side of a road, a street lamp integrated pole fixed above the street lamp foundation, the street lamp foundation being a square reinforced concrete block, the lower part of the street lamp foundation passing through underground pipelines, anchor bolts pre-buried downward from the upper surface of the street lamp foundation, the bottom of the anchor bolts not lower than the upper surface of the underground pipelines, transverse main reinforcements and vertical main reinforcements arranged in the street lamp foundation, an angle steel being arranged between each anchor bolt and the nearest transverse main reinforcement of the street lamp foundation, the vertical side surface of the angle steel being welded to the anchor bolt, and the transverse side surface of the angle steel being welded to the transverse main reinforcement of the street lamp foundation.

[0006] This structure is used in situations where the underground pipelines on the side of the road are complex and the positions of the street lamp foundation and the underground pipelines conflict. After structural calculation, this device ensures that the load requirements of the upper poles of the street lamp facilities are met. First, the reinforcement of the street lamp foundation is laid out, and then the anchor bolts are embedded, and the anchor bolts are welded to the adjacent transverse main reinforcement. Since there are underground pipelines under the street lamp foundation, the length of the anchor bolts is shortened due to the influence of the underground pipelines. This solution makes the main reinforcement of the street lamp foundation and the anchor bolts tightly connected to form a whole, which solves the problem of insufficient tension after the anchor bolts are shortened, and at the same time solves the problem of the conflict between the street lamp foundation and the underground pipeline.

[0007] Preferably, the top surface of the underground pipeline does not exceed 50% of the height above the bottom surface of the street lamp foundation.

[0008] Preferably, the diameter of the underground pipeline does not exceed 50% of the width of the street lamp foundation.

[0009] Preferably, the underground pipeline is a D400-D1000 rainwater pipe or sewage pipe.

[0010] Preferably, the underground pipeline is safely laid in the street lamp foundation; or the upper part of the underground pipeline is laid in the street lamp foundation and the lower part of the underground pipeline is buried under the street lamp foundation. The underground pipeline can be fully buried or half buried in the street lamp foundation according to the design height.

[0011] Preferably, the anchor bolts are arranged in a ring, connected and fixed to the flange at the bottom end of the street light integrated pole, and cable tubes are arranged inside the ring-shaped anchor bolts.

[0012] Preferably, the top of the anchor bolt is 80-120 mm higher than the upper surface of the street lamp foundation. The upper surface of the street lamp foundation is 150 mm lower than the ground plane. After the anchor bolt is connected to the flange of the street lamp integrated pole, the upper part is encapsulated with C20 concrete until it is flush with the ground plane.

[0013] Preferably, the street lamp foundation adopts concrete with a grade of C25 or above; a plain concrete cushion layer is provided under the street lamp foundation, and the plain concrete cushion layer adopts C15 concrete.

[0014] Preferably, the top of the anchor bolt is 80-120 mm higher than the upper surface of the street lamp foundation.

[0015] Preferably, a street light is arranged on the top of the street light integrated pole, and a support pole for traffic signs and monitoring equipment is provided on the upper part of the street light integrated pole toward the road side.

[0016] The utility model connects the main reinforcement of the street lamp foundation with the anchor bolts tightly to form a whole, solves the problem of insufficient tension of the anchor bolts after shortening, and solves the problem of position conflict between the street lamp foundation and the underground pipeline.
