However, the special equipment for the ditcher has the following limitations in practical application:
1. the requirements on ground conditions are high. The construction mode of the existing ditcher equipment is to cross two sides or one side of a groove to construct the groove, so that the two sides or one side of the groove are required to have relatively flat ground for the movement of the ditcher;
2. and the construction environment of a special stratum. The existing ditching machine equipment cannot be suitable for high-hardness rock stratums, and particularly when trenches are dug in stratums with complex geological conditions such as hills and mountains, the construction efficiency is reduced, the loss is increased, and the failure rate is increased along with the increase of the rock strength;
3. the sectional shape and the size range of the excavated groove are limited. The existing ditcher equipment is limited by the size of an excavating mechanism, so that the positioning and slotting one-step forming of grooves with large sections such as pipelines and the like and grooves with any shapes cannot be realized.
Through the depth retrieval, the prior Chinese utility model patent with the publication number of 2021.11.09 and the publication number of CN 214660183U discloses a mobile special-shaped section hard rock tunneling machine, which comprises a telescopic outer cylinder, a telescopic inner cylinder, a walking part, a rotary table, a cutting arm, a cutting part and a muck cleaning device, wherein a telescopic push-pull driving part for driving the telescopic inner cylinder to move back and forth is arranged on the telescopic outer cylinder; a walking push-pull driving part for driving the walking part to move up and down is arranged on the telescopic outer cylinder; the rotary table is hinged at the front end of the telescopic inner cylinder, and a first swing driving part is arranged between the telescopic inner cylinder and the rotary table; the cutting arm is hinged to the front portion of the rotary table, and a second swing driving portion is arranged between the rotary table and the cutting arm. Although the heading machine can excavate hard rocks, the heading machine cannot be applied to trench excavation of high-strength stone square sections.
Therefore, for the trench excavation of the high-strength stone square section, no special mechanical construction equipment exists at present, and the conventional blasting method or breaking hammer is generally adopted for construction.
The risk of early explosion, refusal explosion, people injury caused by uncontrolled explosion, nearby buildings, communication, electric power or other facilities damage in the artificial explosion and potential safety hazard; the excavator and manual blasting ditching can not be controlled to form a ditch shape, the ditch walls are staggered with dog teeth, the ditch bottom is fluctuated and uneven, the section size of the ditch can not be controlled in the optimal state, and the forming quality can not be ensured; the one-time investment equipment is more, the slag removal workload is large, and the section of the channel formed by manual blasting is not easy to control, so that the backfill volume is large, and the construction cost is increased; the excavating of the excavator and the manual blasting need to be performed in a layered mode, the excavating time is long, the working time for cleaning the slag stones is long, the time for cleaning and trimming the roots of the grooves is long, the excavating efficiency is low, and the construction period is influenced.
