Description
Technical Field
The utility model relates to a module board, concretely relates to soft rock tunnel bottom laying module belongs to soft rock tunnel application.
Background
In recent years, with the increasing of coal mining depth, roadway mine pressure is more and more severe. In some deep-well coal mines, full-section shrinkage deformation occurs soon after the roadway is excavated, particularly the roadway bottom bulge seriously influences the transportation of underground personnel and equipment, and although the underground personnel and equipment are repeatedly repaired, the transportation requirement can be just barely maintained; frequent priming and bottoming cause high labor intensity of workers and high roadway maintenance cost, which become main factors restricting high-yield and high-efficiency production of mines.
Even in the areas such as inner Mongolia and Xinjiang in the western part of China, although the tunnel burial depth is relatively small, because the bottom plate of the tunnel is mostly provided with mineral components such as illite, kaolin, chlorite clay and the like, the minerals are easy to expand and soften when meeting water, the overall strength of the rock body is affected, and the occurrence of the bottom heave phenomenon is induced.
Due to the differences of geological conditions, properties and stress states of the heaving surrounding rocks of the roadway, the modes and mechanisms of the floor rock stratum to be swelled into the roadway are different. Common construction measures include floor anchor rods, floor grouting, roadway floor grooving and pressure relief, closed roadway supports and the like. Aiming at different roadways, because the service life is different, the adopted prevention and treatment measures are also different, and the purpose is to meet the requirements of equipment and personnel transportation in the service period.
The treatment process of the roadway heaving floor can seriously affect the normal transportation of the roadway, and further restrict the high-efficiency production of the whole mine. In the gate roadway with frequent bottom heave, the service life is short, and only basic transportation needs to be met. Therefore, only temporary bottom raising and leveling measures are generally taken, complex measures such as anchor rod striking, concrete bottom laying and the like are not adopted, and a method for laying steel plates, wood plates and even waste belts in a bottom bulging area (soft bottom area) is adopted in many coal mines. In the practical use process, however, the steel plate is inconvenient to lay and withdraw due to high cost and heavy weight, and the steel plate is difficult to reuse due to serious corrosion problems in some high-salt mines; the single steel plate can also have a 'drifting' phenomenon in the frequent rolling process, so that the use is influenced; the steel plate can also generate the phenomenon of warping in the process of frequent rolling, the trackless rubber-tyred tire can be cut, and potential safety hazards exist. The wood board is not suitable because of insufficient strength and easy softening by soaking in water. In a roadway with concrete paved bottom, a vehicle needs to clean a broken road surface and re-bottom after repeatedly rolling, the concrete is long in hardening and curing time, the normal auxiliary transportation requirement of a mine is seriously influenced, and the serious problem which troubles the normal production of the mine is caused.
