Abstract

The invention relates to a gas lift double-shaft slot forming machine, which comprises a high-pressure gas inlet pipe, a grout outlet bent pipe, a grout outlet steel pipe and two guide tracks fixed on two sides of the grout outlet steel pipe, wherein a hydraulic motor A is in shaft connection with a power shaft A, and a hydraulic motor B is in shaft connection with a power shaft B; and the two hydraulic motors and two support shaft sleeves are fixed on a cross beam, and the two power shafts are provided with a plurality of T-shaped knives respectively. The gas lift double-shaft slot forming machine is a special tool for slot formation of underground continuous walls.

Description

1. Technical field [0001] The invention relates to a groove forming machine, in particular to a gas-lift double-axis groove forming machine for an underground continuous wall. 2. Background technology [0002] At present, the groove forming machines used in the construction of underground diaphragm walls can be roughly divided into three types according to their mechanism: bucket type, impact type and four-rotation type. Although the above equipments have their own characteristics, they all have the disadvantages of low trough forming efficiency and high cost of building equipment. 3. Contents of the invention [0003] The invention provides a gas-lift double-axis groove forming machine with high groove forming efficiency, low manufacturing cost and convenient maintenance. [0004] The present invention is achieved through the following technical solutions. [0005] A gas-lift double-shaft slotting machine, including a high-pressure inlet pipe, a pulp discharge elbow, a ...
