Organic composite material hand hole



Product Features:
Traditional brick handholes have drawbacks such as cumbersome construction steps, excessive restrictions, and high construction difficulty, which seriously affect the construction period and quality of optical cables. In long-distance oil and gas pipelines laid in the same trench, traditional brick handholes are difficult to synchronize with pipeline construction in terms of construction period. During the construction process, there will be large usage areas, difficulties in handling residual bricks, and cement waste, which will have a serious impact on the environment, In the way of laying silicon pipes before blowing cables adopted by long-distance pipelines and peer Telecommunications engineering, brick handholes should be constructed before pipelines, which will lead to inaccurate positioning of handholes, inaccurate distribution of optical cables, and increased loss. Mortar covers are required for traditional handholes, and mortar covers need to be reused for maintenance. Maintenance takes a long time and requires heavy workload.



Practice has proven that organic composite material handholes are lighter in weight, easier to transport, stronger in toughness, stronger in bearing capacity, and more adaptable than traditional handholes. In the construction of communication pipelines, organic composite material handholes greatly simplify the construction steps, eliminate the limitations of difficult brick laying and spatial measurement, and high in construction difficulty, greatly saving construction, effectively reducing the impact of construction waste on the environment, and also saving time, The synchronous construction of optical cables and pipelines has basically solved the impact of the construction process on local residents' agricultural production, effectively reducing the difficulties in operation and maintenance caused by cumbersome process settings. The setting of composite material handholes can be installed immediately according to the position of the optical cable blowing, and can be carried out simultaneously with the installation of the optical cable blowing and connecting handholes, reducing the process of secondary opening of the handholes and greatly saving the construction period.

4、 Product features:
This utility relates to an organic composite material hand hole, which includes a hole body and a hole cover. The hole body is in a can shape, and there are 8 evenly distributed hole body ribs around the hole body. The hole cover is a step hollow disc, and the hole body is connected to the hole cover. The area of the small outer diameter disc on the inner side of the hole cover is equipped with hole cover ribs, which are in a rounded square frame structure, and each of the four rounded corners extends a strip like structure to connect with the small outer diameter disc of the hole cover, There is a concave point on each of the four inner sides of the hole cover reinforcement perpendicular to the hole cover plane. The handhole refers to a reduced manhole, which is installed for the installation, disassembly, cleaning, and maintenance of internal devices of the equipment.
