Problems solved by technology
At present, the embedded filling method widely used at home and abroad is artificial embedded filling. Since most of the flexible packing products sold in the domestic and foreign markets are plates or columns with rectangular cross-sections, and the packing itself has certain elastic-plastic properties, it is placed on the slope of the dam. It is very difficult to manually embed the V-shaped groove densely. When the external temperature is low and the hardness of the filler increases, the problem of embedding and filling will be more serious.
Therefore, the efficiency of artificial embedding is low and the quality of embedding is not very ideal
[0005] The patent No. ZL03266644.6 for the flexible filler extruder patent proposes a flexible filler extrusion equipment for on-site embedded filling construction, which can ensure good embedded filling compactness and interface bonding effect, and the construction efficiency is higher than that of manual embedded filling. Filling has been improved, but there are also some defects that limit its practical application in engineering. These defects are as follows:
[0006] 1. The process is cumbersome
It is necessary to drill holes on the concrete panel to install expansion bolts, and then use expansion bolts and pressure plates to fix the outer formwork; the length of the outer formwork is limited, and after one or two meters of embedding, the outer formwork and expansion bolts must be removed, moved forward and then re-fixed; Simultaneous drilling can damage the concrete surface
[0007] 2. The operation is difficult
[0008] 3. Low efficiency
Due to the need to continuously remove the mold and fix the mold, the process of inserting and filling is intermittent. The extruder will stop when it starts to fill a section of the V-shaped groove, and wait for the outer mold to be fixed again, causing the machine and operators to be idle.
[0009] To sum up, in order to solve the problems of low efficiency and poor quality of artificial embedding and at the same time eliminate the deficiencies of the prior art, the present invention proposes a flexible filler embedding machine for face rockfill dams

Embodiment Construction
[0032] As shown in Figure 1 and Figure 2, the flexible packing 1 is filled into the packing chamber 8 from the feed port 7, the power machine 3 drives the extrusion screw 9 to rotate after passing through the governor 4, and the heater 10 makes the packing temperature in the packing chamber 8 Elevated, and extruded from the die mouth of the die head 11 by the action of the extruding screw 9; the walking part of the filling machine includes the support wheel 5, the steering device 12 and the height adjustment device 6 of the fuselage, and the traction part of the filling machine includes Hoist 14, hook 13 and wire rope 15.
[0033] The operation of the embedded filling machine is shown in Figure 3. The winch 14 fixed on the top of the dam pulls the main machine through the wire rope 15 to travel across the gap on the concrete panel 2; At the weight balance point on the side of the machine main body, the embedded filling machine can better realize the embedded filling of the joi...

The invention relates to an engineering machine, in particular to a flexible filler implanting machine for implanting flexible filler in the panel joint of the panel rock filled dam concrete. The construction quality of the flexible filler seal layer on the surface of the panel rock filled dam is concerned with safety and reliability of the dam. The problem of low efficiency and low quality of filler implanting always worries the engineering technicians. The design of the invention strives for simple equipments and procedures, so as to achieve the effects of easy equipment maintenance and simple operation in the actual construction, and make the construction quick and high quality. The invention is characterized in that a machine body is provided, in which a power machine is arranged. The powder machine is connected with an extrusion screw in a filler chamber by a governor; the filler chamber is provided with a feeding opening; the machine body is provided with a walking device; the outlet of the filler chamber is provided with a die head and / or an opening shape for controlling the extruded cross section shape of the filler.
Description
technical field [0001] The invention relates to an engineering machine, in particular to a flexible filler embedding machine used for embedding flexible filler in concrete face joints of face rockfill dams. Background technique [0002] The concrete face rockfill dam is a dam form widely used in the construction of hydropower stations at home and abroad. It uses the rockfill body as the main force-bearing structure to bear the reservoir water pressure, and the reinforcement poured from bottom to top on the facing surface of the rockfill body Concrete panels are anti-seepage structures. Due to factors such as the settlement and deformation of the dam body, the concrete panels need to be poured in blocks, so that dozens of joints are formed between the panel blocks, the plinth and the panel blocks that are integrated with the surrounding mountains. Seepage, the seepage will take away the small particles in the rockfill body, forming a gradually expanding seepage channel, whic...
