Movable facade hard rock slotting machine and construction technology thereof

Abstract

The invention provides a movable facade hard rock slotting machine and a construction technology thereof. The movable facade hard rock slotting machine comprises a crawler travelling mechanism (1) forallowing the slotting machine to move, a working platform (2) for allowing staff to operate, an electric hydraulic pump (3) which controls circulation of hydraulic oil, levelling supporting leg cylinders (4) used for supporting the slotting machine to guarantee integral levelness of the slotting machine and perpendicularity of a cutting blade, a travelling and adjusting operation mechanism (5) used for operating the crawler travelling mechanism (1), a travelling electric control cabinet (6) which supplies power to the travelling and adjusting operation mechanism (5), a cutting machine movingrail rack (7) used for mounting the cutting blade, and a cutting blade up-down moving mechanism (8) used for adjusting the up-down displacement of the cutting blade. According to the movable facade hard rock slotting machine, an electric double-wheel cutting machine is mounted on a chassis of the crawler travelling mechanism, upright post groove lines can be cut on facade hard rock through the cutting blade capable of moving up and down and front and back, then, a cut rock body is broken through a self breaking hammer of the cutting machine or an excavator matched with construction, and upright post grooves are formed.

Description

technical field [0001] The invention belongs to the technical field of cutting equipment for hard rock grooves, and in particular relates to a mobile facade hard rock groove cutting machine and its construction technology. Background technique [0002] In the construction design of the deep foundation pit rib wall at Bashan Station of Chongqing Rail Transit Line 5, the stressed reinforced concrete vertical rib column on the side wall of the foundation pit rib is embedded in the hard rock mass of the natural facade. The rib wall construction needs to make rib wall column grooves in advance. The shape of each column groove is: width 50cm×depth 50cm×height 3m. method of excavation. [0003] Prior art one: the direct demolition method with a jackhammer (i.e. the usual manual excavation method). [0004] This method is the most traditional excavation method. The compressed air generated by the air compressor is used to drive the hand-held jackhammer. Under the action of manpowe...

AI Technical Summary

Problems solved by technology

[0006] 1. The excavation speed is slow, mainly on the 35MPa hard rock, and the pneumatic pick can hardly break it. To break a 50cm wide, 50cm deep, 3m high tank, it takes about 20 hours for 2 pneumatic picks, and the efficiency is low. , the groove shape is poor, and it cannot meet the construction progress requirements at all

[0007] 2. High cost

Eliminate the long construction time and the difficult operation of facade work, resulting in huge labor and mechanical costs

[0008] 3. Potential safety hazards

Due to the large vibration of the breaking hammer on the whole rock, it is difficult to control the boundary of the column groove, causing a large piece or the whole rock to fall off under the strong vibration of the excavator's breaking hammer, causing the column groove to form an irregular shape or no column groove at all.

[0013] 2. Cost increase

This resulted in an increase in the amount of earth and stone to be shipped out and an overconsumption of concrete pouring for the rib wall and rib column by more than 100%
