Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0024] Such as figure 1 A reinforced manhole cover shown includes a circular manhole seat 1 and a manhole cover body 2, and the side of the outer circle of the manhole seat 1 is provided with three layers of pre-embedded rings 3, such as figure 2 As shown, the pre-embedded ring is evenly provided with some long slots 30 along the circumferential direction. When the inspection well seat is pre-buried, cement can enter the position between the pre-embedded rings from the long slots to ensure that the inspection well cover is pre-embedded stably; 1. The inner circle of the upper end protrudes upwards to form a convex ring 10, and the outer side of the convex ring 10 is evenly provided with four limit projections 11, and the lower end of the manhole cover 2 body is provided with a connecting ring 20 that is fastened on the convex ring, such as image 3...

The invention relates to the technical field of manhole covers and discloses a reinforced manhole cover. The reinforced manhole cover comprises a round manhole seat and a manhole cover body, wherein the side surface of the outer circle of the manhole seat is provided with a pre-buried ring; the inner circle of the upper end of the manhole seat is convex upwards to form a convex ring; the lower end of the manhole cover body is provided with a connection ring which is rotatably buckled on the convex ring; a plurality of bolt holes are formed in the top part of the convex ring; countersinks are formed in the manhole cover body, and bolts which are connected with the bolt holes are arranged in the countersinks; a support ring is arranged on the upper end of the inner circle of the convex ring; the upper end surface of the support ring is a conical surface; a reinforcing ring is arranged on the bottom surface of the manhole cover body; the outer side surface of the reinforcing ring is in contact support with the conical surface on the support ring; the part, which is located inside the reinforcing ring, of the bottom of the manhole cover body is provided with crossed reinforcing ribs; and the outer ends of the reinforcing ribs are connected with the reinforcing ring. Therefore, the reinforced manhole cover disclosed by the invention has the beneficial effects of being convenient to change, high in compressive property and long in service life.
Description
technical field [0001] The invention relates to the technical field of inspection well covers, in particular to a reinforced inspection well cover structure. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. Called the inspection well, the inspection well mouth is usually flush with the ground, so a cover is needed to cover the inspection well, which is called the inspection well cover. Manhole covers are usually made of reinforced concrete, metal, reinforced plastics and other materials, and their shapes are based on circles and squares. The usual manhole covers are all in the middle of the road and are easily crushed by the wheels. Some manhole covers are easy to break after being rolled by vehicles for a long time due...
