A tapping device (1) for beverage, including a cooling device and a tapping rod (8) with a tapping cock (14), the tapping rod including a first (50) and a second (52) channel, which channels are in fluid communication with each other adjacent the tapping cock (14), while at least during use a tapping line (48) extends through the second channel, which tapping line is coupled at one end with a container (6) for beverage and at the other end can cooperate with the tapping cock.

The invention aims to provide an integral figure eight-shaped sand block mesh assembling machine comprises an assembly mould, an auxiliary traction machine, an auxiliary sending machine, an auxiliary ultrasonic welding machine, a guide shape plate, a mesh clamp seat, a transition board and an electric appliance control box which are fixed on a frame, an air compressor and supporting parts; the assembly mould, the auxiliary traction machine, the auxiliary sending machine and the auxiliary ultrasonic welding machine are deployed by a pressure cylinder for driving, take compressed air as a power source, sequentially and alternatively move back and forth, work is progressive action, so that a plastic mesh sets spacing in a balanced way and is assembled with a mesh supporting clamp. The speed and the stroke of the parts of the whole machine are stably regulated manually and automatically controlled by an electric appliance. The integral figure eight-shaped sand block mesh assembling machine has the advantages of reasonable structure, safety, reliability, low energy consumption and high efficiency performance, and is ideal machinery for integral figure eight-shaped sand block mesh assembling (production).

The invention discloses a construction method of piles and a drill pipe system special for the piles. The construction method includes the steps that (1) system relocation and emplacement are conducted, specifically, the drill pipe system is moved and emplaced to the set pile position; (2) spinning and sinking are conducted, specifically, the drill pipe system is spun and sunk to the set depth; (3) rotary pulling and lifting are conducted, specifically, the drill pipe system is rotatably pulled and lifted to the set height; and (4) the step (2) and the step (3) are repeated until a first pilemeets the set requirements. According to the construction method of the piles and the drill pipe system special for the piles, according to the initial setting time and the hard setting time of cementsoil, the method of pile planting in multiple time periods is adopted, the regulation limit that ordinary composite piles are implanted within 12-hour working is broken, and the timeliness and the work efficiency are improved; and two sets of hydraulic oil cylinders are arranged on the upper part and the lower part of a pile frame of static pressure equipment, the lower set of oil cylinders holdslower section piles, the upper set of hydraulic oil cylinders holds or supports precast piles, and the problem of pile extension of two-section piles and multi-section piles is solved.

The invention provides a construction method of assembling and starting in a shield tunnel hole. The problems that for construction of an existing shield method, a design and construction technology is large in control difficulty, and the risk is high can be solved. The method comprises the following steps that a borehole-blasting method is adopted for finishing inclined shaft, branch hole, main line tunnel and assembling and starting hole chamber construction; a transport vehicle conveys a shield cutterhead, a shield body, a counterforce frame, steel inclined struts and the like to the assembling and starting hole chamber through an inclined shaft, and assembling and turnover of the shield cutterhead, assembling of the shield body and manufacturing and splicing of the counterforce frame are finished; with the same method, after-shield matching parts are transported to the assembling and starting hole chamber to be assembled, and are drawn to the main line tunnel to be stored; the after-shield matching parts are connected with the shield body, and whole machine assembling and debugging are finished; and during beginning, pipe segments are conveyed in from the branch holes, after all the after-shield matching parts pass through a crossing opening of the inclined shaft and the main line tunnel, and the pipe segments are conveyed in from the inclined shaft until a shield section is constructed. Construction is convenient, the flow is simple and clear, economic and social benefits are high, and the wide application prospects are achieved.
