Combined geotechnical grid stretch-drawing device

Abstract

The invention relates to a combined geotechnical grid stretch-drawing device, which comprises a three-directional connection device and a combined square steel connection section. The three-directional connection device and the combined square steel connection section are assembled into a square framework, fixed rod type sliding blocks are arranged on the lower border and the left border of the square framework, and the upper portions of the fixed rod type sliding blocks are welded with stretch-drawing rods. Adjustable rod type sliding blocks are arranged on the right border and the upper border of the square framework, a fixed lead screw base and a moving screw block are arranged above the adjustable rod type sliding blocks in parallel mode, one end of a lead screw penetrates through the moving screw block and then is clamped in the fixed lead screw base, the other end of the screw rod is connected with an adjusting handle, and a stretch-drawing rod is welded on the moving screw block. The combined geotechnical grid stretch-drawing device can enable a geotechnical grid to be even in relaxation, and is easy and simple to install, adjustable in size, capable of being used repeatedly, and attractive in engineering appearance. The integral framework of the stretch-drawing device is good in rigidity and not apt to deform, so that construction quality can be ensured, and construction efficiency can be improved.

Description

technical field [0001] The invention relates to a combined geocell tensioning device suitable for the construction of geocell concrete, especially in the construction of side slopes such as water conservancy engineering channels and embankments. Background technique [0002] Geocell is a new type of geosynthetics produced by the introduction of foreign technology in my country in recent years. It is a three-dimensional honeycomb structure made of polyolefin as the base material, added with special additives, and welded with high strength. The cell can be folded, and its dimensions can be adjusted according to the needs of the project. When a load is applied to the geocell, the three-dimensional mesh structure of the geocell can restrict the flow of the filling material and strengthen it, resulting in a laterally dispersed flexible structure that converts most of the vertical force into a lateral force. As a result, the actual load is greatly reduced, the bearing capacity is...

Problems solved by technology

However, the current geocells have the following problems: because the geocells are flexible materials, in the process of concrete pouring, if the process is not handled properly, the grids of the cells are often deformed, which not only affects the appearance of the cell pattern, but also affects The concrete structure of the cell has certain influence; the overall rigidity of the tensioning device frame welded by the old-style angle steel is not enough, and it is easy to deform, which affects the construction quality; the reuse rate of the frame welded by the angle steel is not high, and it is difficult to clean; a set The tensioning device can only correspond to the cell grid of the corresponding specification, and it is necessary to manufacture multiple sets of devices of various specifications to meet the construction requirements, which increases the construction cost; since the tensioning device is welded with fixed-size angle steel, it cannot be used for different The working surface can be freely expanded and contracted; it can only be supported in the up and down direction, and cannot be supported in the left and right directions
