specific Embodiment

[0014] Accompanying drawing is a kind of specific embodiment of the present invention, specifically tells about through 4 below

[0015] 1. Pipeline layout

[0016] In the groove sawing process of the groove sawing machine of the present invention, the circulation mode of the slurry has positive circulation and reverse circulation, that is, water injection and suction, and the layout of the pipeline is also designed because of the two modes. The water injection pipeline is divided into water inlet pipes (2 ) and the water inlet rubber hose (3), the water inlet pipe is made of steel pipes one by one, and the two ends of each joint are provided with threaded fasteners. The water inlet hose is divided into two branches, each of which feeds water into a group of saw blades, and the water is sprayed out from the water nozzle.

[0017] The suction pipeline is divided into a sand-absorbing pipe (1) and a sand-absorbing rubber pipe (4). The sand-absorbing pipe is arranged in the same...

Abstract

The invention discloses a double-saw slot sawing machine comprising a water inlet tube (2), a water inlet rubber (3), a sand suction tube (1) and a sand suction rubber tube (4), wherein the water inlet rubber (3) respectively supplies water to two groups of saw blades, and the sand suction rubber tube (4) adsorbs sand to two groups of saw blades. A diving reduction box (10) is positioned in the middle of the slot sawing machine; an eccentric shaft is installed below the diving reduction box and is provided with an upper sealed axle sleeve (18) and a lower sealed axle sleeve (5); two axle sleeves are respectively connected with a left connecting rod (7) and a right connecting rod (6), wherein the connecting rod (7) is hinged with the middle of a swing arm (8), and the connecting rod (6) is hinged with the upper end of a swing arm (9); a drill point (15) capable of rotating from left to right is positioned on the top center of the slot sawing machine between a shifting fork and two shifting needles; two triangle tool rests (16) and (17) are respectively positioned on the left and the right of the lower end of the slot sawing machine; inclined saw blades (12) are evenly distributed according to certain length on the bottom of the tool rest; a water spray nozzle (11) is positioned between each two saw blades. The invention is a special machine tool for building underground impervious walls.

Description

1. Technical field [0001] The invention relates to a groove sawing machine, in particular to a groove sawing machine for an underground anti-seepage wall. 2. Background technology [0002] At present, most of the groove-forming equipment for building cut-off walls have the characteristics of shallow groove depth, low efficiency, inability or difficulty to construct ultra-thin wall sections, expensive equipment, and complex structures. 3. Contents of the invention: [0003] The present invention makes up for the shortcomings of the above grooving equipment, and provides a high-efficiency, low-cost, double-saw grooving machine whose wall thickness can be adjusted quickly at any time and at any time, with large grooving depth and simple structure. [0004] The present invention is achieved through the following technical solutions: [0005] A double-saw grooving machine, comprising a water inlet pipe (2), a water inlet rubber hose (3) for respectively supplying water to two ...
