The automatic construction equipment disclosed by the invention is capable of realizing the function of clipping-piling integrated automatic construction for the reservoirs, does not need manual operation, and is high in reservoir construction speed and working efficiency, and capable ofautomatically travelling on the bumpy and uneven grounds of the reservoirs for construction and realizing mechanical automatic step-by-step construction.

The invention discloses a secondary vibration system of a pile driver and a control method thereof. The vibration system includes: a mode selector for obtaining the selection result of the vibration mode by the user; an oil supply module including a first main pump and a second main pump , in the primary vibration mode, the pressure oil of the hydraulic vibration motor is only supplied by the first main pump; in the secondary vibration mode, the pressure oil of the hydraulic vibration motor is supplied by the first main pump and the second main pump together, the hydraulic vibration The motor is used to generate the excitation force; the first pressure sensor is used to obtain the working pressure of the first main pump; the control module has a controller electrically connected to the first pressure sensor, and is used to select the result according to the user and / or The working pressure of the first main pump realizes switching control between the primary vibration mode and the secondary vibration mode. The secondary vibration system and control method of the pile driver reduce the complexity of hydraulic pipeline layout, enhance the exciting force of the pile driver with secondary vibration, increase the pile driving speed and reduce fuel consumption.

The invention discloses a combined hammer head for a hydraulic pile hammer. The combined hammer head is applied to a pile hammer hammering system of the hydraulic pile hammer in a pile basis construction. The hammer head comprises a hammer body with a hollow interior; a striking head is arranged at the bottom of the hammer body; an oil cylinder piston rod is connected with the top of the hammer body; a metal grain filler is filled in the hollow cavity of the hammer body; the hammer body is formed by stacking and connecting a plurality of metal plates; a lower plate at the bottom and an upper plate at the top are closed; a plurality of middle plates in the middle are arranged as frame-shaped hollow plates; after the frame-shaped hollow plates are stacked, the hollow cavity in the hammer body is formed. According to the invention, the stress waveform during a striking process of the hammer head is effectively improved, the peak of the stress waveform is reduced to the lowest required value and the transferring time of the stress waveform under a peak state is prolonged, the transferring efficiency of the strike energy and the piling speed are increased while the impact force endured by the pile hammer and the pile is reduced, the service life of the pile hammer is prolonged and the pile is protected from being damaged.

The invention relates to a three-dimensional movable SCP forming system in a centrifugal test. The system is composed of a sleeve, a piston, sliding wheel assemblies and a hand-powered heavy piling hammer, wherein the sleeve and the piston are needed in the piling process. The sleeve is a hollow cylinder. The piston is a cylindrical rod. The verticality of the sleeve which is clamped in the middle is guaranteed through four sliding wheelslocated on the two sides of the sleeve. Sliding chutes can be connected with a model box used in the test through bolts at the two ends and are fixed above the model box. The hand-powered heavy piling hammer is composed of an upper hand-powered structure and lower guide rails. The upper hand-powered structure can drive the heavy hammer to reciprocate upwards and downwards by shaking a handle of the upper hand-powered structure, so that the heavy hammer strike the top of the piston downwards, and sand is compacted through the piston; meanwhile, a wheel at the top of the upper hand-powered structure is rotated, so that the heavy hammer and a linkage structure of the heavy hammer move upwards and downwards, and the position is adjusted. The lower guide rails comprise two sets of guide rails which are mutually perpendicular on the horizontal plane. The upper hand-powered structure can slide freely in the direction of two guide rails. According to the three-dimensional movable SCP forming system, the SCP forming process can be really simulated in the centrifugal model test; the three-dimensional movable SCP forming system is not only convenient to use and efficient, but also capable of guaranteeing verticality, continuity, compactness and the like of a sand pile, thereby being capable of well providing service for relevant research work.
