Enough volume and weights of reduction gravity-type structure, save project cost, and it is at this stage and following a large amount of green, low to adapt to China
Carbon, environmental-friendly ocean civil engineering construction demand.
Summary of the invention
In view of this, the non-slip mat can increase the present invention is directed to propose a kind of for increasing the pitch non-slip mat of coefficient of friction
Add the coefficient of friction between marine traffic engineering field gravity-type structure and contact surface, and then reduces the weight and body of gravity-type structure
Product, reduces the requirement of basement process, achievees the purpose that save material, reduces project cost.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
It is a kind of for increasing the pitch non-slip mat of coefficient of friction, including bituminous concrete and be set in bituminous concrete
Etting, reinforcing rib, pre-buried lifting rope, gasket and Anti-skid sheet, further include the pre-buried stud being inserted in the bituminous concrete.
Further, the gasket, Anti-skid sheet pass through the pre-buried lifting rope series connection.
Further, the pre-buried stud of the reinforcing rib and the pre-buried lifting rope pairwise orthogonal are arranged.
Further, the pre-buried stud is inserted in the upper surface of the bituminous concrete.
Further, the non-slip mat is with a thickness of 3cm-10cm.
Further, web pre fetching shown in is metal, Ni Lun or glass reinforced plastic.
Further, the pre-buried stud height 10-20cm, diameter are greater than 5mm, and material is regular reinforcement, screw-thread steel
Muscle or steel pipe.
Further, the pre-buried lifting rope length is greater than 10cm, and material is metal or nylon.
Further, the gasket is rectangle, and material is steel or copper.
Further, the Anti-skid sheet is square, and material is steel or copper.
Compared with the existing technology, pitch non-slip mat of the present invention, which has the advantage that, can significantly improve caisson, chest
The coefficient of friction of the gravity-type structures such as wall reduces the weight or size of gravity-type structure, reduces the requirement to basement process, in turn
It saves material, reduce project cost.
