The utility model discloses a PVA concrete vibration-absorbing shaft cover, which comprises a shaft cover body, a shaft seat and a vibration-absorbing member. The shaft seat is fixed at both ends of the shaft head along the moving direction of the vehicle. The shaft seat includes a bearing bearing of the bearing shaft cover. The vibration-absorbing member is arranged on the vertical and horizontal planes of the bearing bearing seat, and the shaft cover body and the shaft cover are connected with the shaft head. The shaft cover body is an arc arch structure, the arc arch structure and its end are supported on the bearing support, and the shaft cover body and shaft seat are PVA reinforced concrete members. The shaft cover body in the utility model adopts an arc arch structure, which can effectively reduce the vertical force and vibration of the shaft cover under the action of vehicle load, further utilize the compressive performance of concrete, improve the impact resistance of the shaft cover, ensure the integrity of the shaft cover body structure, and greatly reduce the vibration of the vehicle to the shaft cover. Cumulative damage, while effectively reducing noise effects, has good bearing and descending effects and permanent effects.
【技术实现步骤摘要】
一种PVA混凝土减振井盖
本技术属于市政与道路工程
,特别涉及市政道路工程中井盖技术。
技术介绍
凡是安装自来水、污水、雨水等公用设施的地方都需要安装井盖。随着我国道路交通的飞速发展,井盖的市场使用量巨大。现有的井盖材料大多数为钢筋混凝土、球墨铸件或者铸铁构件,其材质脆性大,易断裂,小车尤其是重量卡车行驶会发生强烈振动,产生噪音,极易产生累积损伤,由于具有经济价值经常发生被盗现象。在现实应用中,井盖被车辆碾压而破损情况或井盖被盗现象时有发生,导致道路及设施安全性下降,会造成交通问题。
技术实现思路
本技术提供一种PVA混凝土减振井盖,所述井盖本体和井座采用PVA钢筋混凝土结构,并设有减振构件,本技术中所述井盖结构简单,并且能提供井盖的受力性能及抗冲击性能,并降低噪音影响。为解决上述问题,本技术采用下述技术方案。一种PVA混凝土减振井盖,包括井盖本体、井座及减振构件,所述井座固定在井口沿车辆行进方向的两端,所述井座包括承载井盖的承载支座,所述减振构件设置在承载支座垂直面和水平面,所述井盖本体与所述承载支座相适配,所述井盖本体为弧拱形结构,所述弧拱形结构及其端部支承在承载支座上,所述井盖本体及井座为PVA钢筋混凝土构件。进一步地,所述减振构件为叠合橡胶构件。进一步地,所述井盖本体的上端面与与井座的上端面齐平。本技术的有益效果为:本技术中所述井盖本体采用弧拱形结构,可以有效地降低车辆荷载作用下井盖垂直受力和井盖振动,进一步利用混凝土的受压性能,提高井盖的抗冲击性能,保证井盖本体结构的完整性,并且弧拱形结构能降低配筋率,有效降低井盖受压性能,因此可以减轻井盖本体重量 ...
