Plane arch gate Characteristics and Application :
It is widely used in water conservancy and hydropower, municipal construction, water supply and drainage, aquaculture, agricultural water conservancy construction and other projects.
The gate structure is reasonable, easy to install, easy to operate and easy to manage.
It can be used in pH = 6-8.
The normal water seepage is l ≤ 0.07l/m.s.
According to the structure form of the gate, it can be divided into PZ plane flat door and PGZ plane arch gate, and can be divided into integral type and assembled type.
When the water outlet is more than or equal to 3 meters, it is a double lifting point gate.
The series of gates are mainly used for water stop under positive pressure. The reverse water stop gate can be manufactured according to the needs of users.
Mechanical hard sealing is adopted in structure, and rubber sealing can also be used for bottom sealing of large gate. According to the user's requirements, copper inlaid or stainless steel embedded waterstop can be used.
The normal working head of the gate is 1-6m, and it can also bear certain reverse water head. In order to meet the requirements of users, high head gate can be manufactured.
The gate shall be installed as a whole and poured in the second stage. The water sealing gap between the gate and the gate frame shall be adjusted to less than 0.3mm before the second stage pouring.
When pouring concrete, the mortar flowing into the gap between the gate, gate frame, inclined iron and baffle must be removed to prevent the impact of mortar solidification on the opening and closing of the gate.
The upper and lower frames of the gate are provided with fixed blocks to prevent the gate from sliding out during transportation and hoisting. After installation and solidification (before use), the fixing block of the upper gate frame and the fastening bolt of the lower frame shall be removed before starting.
When opening and closing the gate, attention should be paid to the upper and lower plate limit position of the gate to avoid damaging the gate or hoist
