Description

Technical Field

[0001] This utility model relates to the field of power engineering facilities technology, specifically to a prefabricated PC power box culvert component. Background Technology

[0002] In the construction of urban power transmission channels, power box culverts serve as important carriers for the protection and laying of power facilities. Traditional construction of power box culverts often employs cast-in-place technology, but this technology has many shortcomings.

[0003] The construction process is fraught with challenges due to the lengthy time required for cast-in-place concrete pouring, the large amount of wet work involved, and the extended curing time. This results in a prolonged construction period, hindering the rapid reopening of the culvert to traffic and disrupting normal urban traffic flow. Furthermore, groundwater levels significantly impact construction, necessitating the lowering of groundwater to below 0.5m below the foundation elevation before concrete foundation pouring. This increases construction costs and is detrimental to environmental protection. On-site cast-in-place concrete exhibits lower impermeability than factory-precast concrete, making it prone to leakage and affecting the culvert's functionality. Cracks are also susceptible to appearing in cast-in-place concrete channels, leading to leakage and impacting structural stress. Additionally, the use of rubber waterstops for segmented culvert connections presents challenges, including poor resistance to uneven ground settlement at joints and difficulties in ensuring the quality of concrete pipe waterstop interface construction. Moreover, on-site cast-in-place culverts are prone to fracture under external loads (such as earthquakes), and the poor on-site production conditions necessitate increased safety margins and material usage in structural calculations. Therefore, it is necessary to design a precast PC (polycarbonate) power culvert component. Utility Model Content

[0030] Please see Figures 1-4 This utility model discloses a prefabricated PC power box culvert component, including the box culvert body 1;

[0031] The main body 1 of the box culvert is made of precast PC material, and its interior is provided with an electrical storage cavity 2 for accommodating electrical facilities;

[0032] The two ends of the box culvert body 1 are respectively provided with a first connecting part 3 and a second connecting part 4 for connecting adjacent box culvert components;

[0033] The first connecting part 3 includes a plug 5 disposed on one end face of the box culvert body 1. The end of the plug 31 is provided with a guide slope to facilitate the insertion of the plug into the slot. An elastic sealing sleeve 6 is sleeved on the outside of the plug 5. The elastic sealing sleeve is a water-swellable rubber sleeve. The water-swellable rubber sleeve will expand when it comes into contact with water to enhance the sealing effect.

[0034] The second connecting part 4 includes a slot 7 disposed on the other end face of the box culvert body 1 and adapted to the plug 5. The inner side wall of the slot 7 is provided with a sealing groove 8 that cooperates with the elastic sealing sleeve. When the plug is inserted into the slot, the elastic sealing sleeve is embedded in the sealing groove to achieve a sealed connection.

[0035] In this utility model, a reinforcing rib structure 9 is also provided on the outer side of the box culvert body 1. The reinforcing rib structure 9 includes a longitudinal reinforcing rib 10 arranged along the length direction of the box culvert body 1 and an annular reinforcing rib 11 arranged along the circumference of the box culvert body 1.

[0036] In addition, the bottom of the box culvert body 1 is provided with anti-slip ridges to increase the friction with the installation foundation, the top of the box culvert body is provided with a lifting ring 13 to facilitate lifting operations, and the inner wall of the box culvert body is provided with an insulating coating to enhance the insulation performance of the inner wall.

[0037] Working principle: After the box culvert components are prefabricated in the factory, they are transported to the construction site. The box culvert components are lifted using lifting rings. The connector of one box culvert component is aligned with the slot of another box culvert component. Guided by a guide ramp, the connector is inserted into the slot, at which point the elastic sealing sleeve embeds into the sealing groove, achieving a sealed connection. In case of water leakage, the water-swellable rubber sleeve will expand, further sealing the connection. The reinforcing ribs on the outer side of the box culvert body enhance structural strength, the anti-slip ridges on the bottom prevent displacement, and the insulating coating on the inner wall ensures electrical safety.

[0038] In summary, the components of this utility model are produced using a prefabrication method, which makes quality control easy, construction efficiency high, connection sealing good, and structural strength high, effectively ensuring the safe and stable operation of power facilities.
