Linked piston type plastic sealing material forming system

Abstract

The invention relates to a linked piston type plastic sealing material forming system. The invention is intended to provide the linked piston type plastic sealing material forming system which is structurally simple and light, is convenient to transport and is low in energy consumption. The technical scheme of the invention is as follows: the linked piston type plastic sealing material forming system is characterized by comprising a speed-regulating rack winch, a pulling rope, a trolley, a plastic sealing material forming device and an industrial control module for controlling the rack winch and the plastic sealing material forming device, the rear end of the trolley is connected with one end of the pulling rope, the other end of the pulling rope is wound on the rack winch, and the plastic sealing material forming device is mounted on the trolley. The linked piston type plastic sealing material forming system is applicable to water conservancy and hydropower project construction machinery.

Description

technical field [0001] The invention relates to a linkage piston type plastic waterproof material forming system. It is suitable for construction machinery of water conservancy and hydropower projects. Background technique [0002] The joints of concrete face rockfill dams (vertical joints formed between the face plates and the peripheral joints formed between the face and the surrounding toe plate) are the first line of defense for face seepage control of face dams and an important part of the overall seepage control of the dam. Therefore, the construction quality of surface water stop is related to the reliability and safety of dam seepage control. [0003] At present, the widely used plastic water-stop material molding method is manual construction, because the plastic water-stop material is packaged in a block shape, and the material body is soft and has a certain elasticity and plasticity, and it is constructed on the slope of the face dam. Water-stop materials have a...

Problems solved by technology

[0003] At present, the widely used plastic water-stop material molding method is manual construction. Since the plastic water-stop material is packaged in a block shape, and the material body is soft and has a certain elasticity and plasticity, and it is constructed on the slope of the face plate dam. In addition, due to the plasticity Water-stop materials have a certain temperature sensitivity. During construction in low-temperature seasons, the hardness of the material increases, and manual construction is particularly difficult. The construction efficiency is often low and the construction quality is not ideal.

[0004] Existing panel joint water-stop material molding machines often use screw extrusion and screw extrusion technology. This type of equipment can better adapt to the embedded construction of flexible fillers in the joints of face rockfill dams, but there are also some defects. For: high energy consumption: the screw extrusion process consumes a lot of energy, and a large amount of mechanical energy is used for friction and extrusion of materials and screws to generate heat; the equipment itself is heavy: this type of equipment includes a high-power motor, gearbox, extrusion screw barrel, and the equipment itself Major, inconvenient to transport
