Description

A concrete conveying pipeline for undercut tunnel

Technical Field

The utility model relates to a secretly dig tunnel concrete transportation equipment technical field, concretely relates to a concrete transfer pipe for secretly dig tunnel.

Background

Undercut tunnel/shaft is in the work progress, if do not have the condition when using horizontal transportation, can use perpendicular transportation usually, the very big drawback of perpendicular transportation is exactly that the conveying efficiency is low, especially concrete transportation, traditional transportation mode is put into the hopper with the concrete, by lifting device with the hopper perpendicular transportation to construction department, can have the concrete slump to reduce at this in-process of hoist and mount, and the concrete can glue on the hopper inner wall moreover, the concrete of having of a specified duration can solidify on the hopper inner wall. Still can continue to glue like this when transporting the concrete next time, the hardened concrete who glues at the hopper inner wall probably drops in secondary hoist and mount, fuses into the concrete of hoist and mount, can lead to the quality greatly reduced of concrete like this, and the concrete of hopper inner wall probably glues more moreover, causes the concrete extravagant, and the weight of hopper will increase down reciprocating, and the concrete that can transport also can be less and less, and conveying efficiency can be more and less low.

After the inner wall is solidified, the concrete becomes very hard, and the cleaning difficulty is extremely high. If the dynamics is too big when clearing up, destroy the hopper very easily and warp, extravagant manpower and materials among the clearance process have seriously reduced the efficiency of construction simultaneously.

The explanation of each reference number in the figure is: a flushing water pipe-1; a hoisting ring-2; a steel pipe-3; a flange plate-4; 5, a heat insulation layer; drying the electric heating wire-6; a hopper-7; heightening a baffle-8; and (5) constructing a pipe-9.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, so as to further understand the concept, the technical problems to be solved, the technical features constituting the technical solutions, and the technical effects brought by the technical solutions of the present invention.

As shown in fig. 1, a concrete conveying pipe for a tunnel to be excavated in the underground comprises a steel pipe 3, a hopper 7, a washing water pipe 1, and a drying electric heating wire 6;

the steel pipe 3 is vertically arranged, the lower end of the steel pipe is connected with a construction pipe 9, and the upper end of the steel pipe is connected to the hopper 7;

a drying electric heating wire 6 sleeved on the outer side wall of the steel pipe 3;

the flushing water pipe 1 is arranged above the hopper 7.

The principle of the utility model is that: when the concrete is vertically conveyed, the device is placed above a vertical shaft, the concrete is guided into the hopper 7, and the concrete can be conveyed to a construction position along the steel pipe 3 and the construction pipe 9 during construction. After the conveying finishes, transport this device to other regions and wash, start washing water pipe 1 and wash 7 inner walls of hopper, make in the data send process glue at the concrete of 7 inner walls of hopper down by dashing, wash the switch of accomplishing back switch-on stoving heating wire 6, stoving heating wire 6 generates heat and dries steel pipe 3, avoids 3 inner walls of steel pipe to rust, influences follow-up use. The utility model discloses the normal transportation of concrete has been guaranteed to the device, has improved work efficiency.
