The present application relates to complex stratum pile foundation construction technology field, disclose a kind of riprapping stratum full casing rotary and rotary drilling combined hole construction method, comprising the following steps: leveling construction ground;Pile position lofting is carried out, and guiding positioning structure is set;First section casing with grouting passage is installed on full casing rotary drilling machine, grouting passage is used for grouting;Through full casing rotary drilling machine clamping casing, drive casing press into riprapping stratum, while rotary drilling carries out soil taking;Slurry is injected by grouting passage, and riprapping body outside casing is consolidated to form annular consolidated body;The elevation difference between the soil taking surface of rotary drilling and the bottom end of casing is controlled to be within the preset range, and the following protection wall is formed;Lengthen next section casing, and connect adjacent grouting passage;Until casing penetrates riprapping layer and main sand layer and enters lower stable layer.The present application can solve the problems of difficult riprapping stratum hole forming, easy hole collapse, easy grouting leakage and easy drill sticking.

This invention provides a measuring cup with a lid, comprising: a cup body, a lid, and a handle. The cup body is also provided with graduation marks. It further includes: a snap-fit ​​structure, comprising a first snap-fit ​​element disposed on the edge of the lid and a second snap-fit ​​element disposed on the cup body, the first and second snap-fit ​​elements being releasably engaged; a lid-opening button disposed on the lid and located outside the lid edge near the handle; a movable connecting structure, one end of which is connected to the lid-opening button, and the other end of which is connected to the handle, to be linked with the lid-opening button, so that the lid can open and close as the lid-opening button moves, and remain at any position between a first position on the lid and a second position at the maximum opening; a guide edge is also provided on the inner edge of the lid: the guide edge extends along the inner surface edge of the lid from both sides of the lid-opening button, and the height of the guide edge gradually increases in the direction away from the lid-opening button; a groove is formed between the edge of the lid and the guide edge; and a sealing ring is disposed in the groove.

This utility model discloses a cofferdam structure and construction system for deep mountain canyon areas. The cofferdam structure includes a cofferdam body located between a diversion tunnel and a tailrace tunnel. The cofferdam body is curved and serves to separate the diversion tunnel and the tailrace tunnel. The cofferdam construction system includes the aforementioned cofferdam structure for deep mountain canyon areas. Considering the complex and varied terrain of the construction environment and the layout of the structures, the curved cofferdam body overcomes the constraints and limitations caused by a single directional axis, improving the adaptability and flexibility of the design and enabling it to better adapt to complex environments. Furthermore, the curved cofferdam body also enhances the smoothness and stability of the cofferdam structure, contributing to improved performance and safety in use.

The present application relates to the technical field of material degradation, in particular to a kind of biodegradable material aerobic composting equipment and degradation method.The composting equipment includes reaction bottle, stirring mechanism and auxiliary control mechanism;The stirring mechanism includes main shaft and the rotation driver for driving the rotation of main shaft, the main shaft is provided with stirring rod, the stirring rod is equipped with telescopic cutting knife;The auxiliary control mechanism is used to control cutting knife extension, in working condition, when rotation driver drives main shaft to rotate at speed exceeding threshold value, the auxiliary control mechanism controls cutting knife to extend to cut material.The present application realizes the function that biodegradable material composting process speed linkage cutting knife telescopic and self-adapting switch crushing and stirring, solves the technical problem that traditional composting equipment is not matched due to speed and function and affects crushing or stirring effect.
