A cobble (sometimes a cobblestone) is a clast of rock defined on the Udden–Wentworth scale as having a particle size of 64–256 millimeters (2.5–10.1 in), larger than a pebble and smaller than a boulder. Other scales define a cobble's size in slightly different terms. A rock made predominantly of cobbles is termed a conglomerate. Cobblestone is a building material based on cobbles.

The invention provides an unpowered automatic impurity removal device special for river sand mining equipment. A conical fence (1) with the diagonal plane bottom is connected to a cylindrical hollow base (2) which is matched with the diagonal plane in diameter. A circular platform (4) extends from the matching position towards outside of a circle center along the diagonal plane, the diagonal plane bottom of a cylindrical hollow cap (3) is matched and connected with the outer edge of the circular platform (4), and the lowest position of the diagonal plane of the circular platform is provided with an impurity discharge opening (6). By means of the device, all impurities such as cobblestone, aquatic plants, plastic bags and branches can be cleared off automatically without power, manual impurity removal in the traditional technology is avoided, and the device is simple in structure, and low in cost, and has high practical value.

Improved structure of shield machine applied to water-rich sandy cobble stratum and construction method
The invention discloses an improved structure of a shield machine applied to a water-rich sandy cobble stratum. The improved structure comprises a cutter head, cutter seats, a stirring bar, a centralhob, a soil bin, a foam system, an external circulating water system and a slag discharging system. The improved structure is characterized in that repair welding of grating wear-resistant welding isperformed on the circumference and a panel of the cutter head, the cutter seats and the stirring bar respectively; a grating plate for blocking cobbles with grain size larger than that conveyed by a screw conveyor from entering the soil bin is added at a slag inlet of the cutter head; a water pipe is added to the external circulating water system, one end of the water pipe communicates with a water outlet of an external circulating water radiator, and the other end of the water pipe communicates with the soil bin after penetrating through a partition plate; and the water pipe is in serial connection with a pneumatic control valve, a flowmeter and a one-way valve sequentially from the water outlet of the external circulating water radiator to the partition plate of the soil bin. Continuoustunneling time is increased, the continuous tunneling distance is increased, and continuous rapid tunneling construction can be performed during continuous tunneling. The invention also discloses a construction method of shield tunneling in the water-rich sandy cobble stratum.
