This invention discloses a high-efficiency leveling and defoaming mechanism for self-leveling mortar, comprising a main body with an installation groove, wheels on the lower ends of both sides of the main body, a cover within the installation groove that slides within the groove, a first automatic telescopic rod at the upper end of the cover connected to the installation groove, a vacuum pump at the upper end of the cover with an air inlet connected to an air pipe, and a barometer inside the cover, a sealing ring at the lower end of the cover, and a control panel at the upper end of the main body. In this invention, the cover is pushed downwards by the first automatic telescopic rod, covering the self-leveling mortar laid on the ground. The sealing ring creates a relatively sealed environment. The vacuum pump operates to remove air from inside the cover, reducing the air pressure. As the air pressure decreases, air bubbles in the mortar expand, float to the surface, and burst, effectively removing air bubbles from the self-leveling mortar and ensuring the construction effect of the self-leveling mortar.

The utility model relates to waterproof concrete technical field discloses a kind of high-strength waterproof concrete special efficient mixing equipment, including mixing drum, the inside of the mixing drum is provided with stirring mechanism, the stirring mechanism is used to stir cement, the bottom right side of the mixing drum is provided with discharge mechanism, the discharge mechanism is used to discharge cement, the top of the mixing drum is fixedly connected with mounting frame board, the top of the stirring mechanism is provided with telescopic mechanism, the top left side of the mounting frame board is provided with water inlet mechanism.In the utility model, when the installation rotating block drives extension rod and stir bar rotate, the broken stirring column breaks up high-hardness aggregate agglomeration, the helical stirring cage cooperates with stirring blade to form three-dimensional stirring field, so that cement paste, aggregate and admixture are fully mixed under the action of centrifugal force and friction force, to ensure that the problem of insufficient stirring intensity and uneven dispersion is effectively solved, to meet the production needs of high-strength materials.

The application aims at the problem of long process connection time, and provides a highland tunnel waterproof and drainage integrated construction device, relating to the technical field of tunnel waterproof and drainage, comprising: a mobile trolley arranged along the longitudinal direction of the tunnel and provided with a walking mechanism at the bottom; a waterproof operation unit arranged at the front of the mobile trolley and comprising a waterproof plate winch mechanism, a hot melt welding mechanical arm and a grouting assembly, the waterproof plate winch mechanism is used for unwinding the waterproof plate, the hot melt welding mechanical arm is used for fixing the waterproof plate on the surface of the initial support of the tunnel, and the grouting assembly is used for injecting filling slurry between the waterproof plate and the initial support; the application realizes waterproof and drainage integrated construction, so that the waterproof layer and the drainage groove are constructed synchronously and seamlessly overlapped, and the leakage hidden danger of the joint caused by the separation of traditional processes is completely eliminated.

The invention discloses a device for safely adding a temporary plugging material into fracturing operation and a using method of the device, and belongs to the technical field of oil and gas field fracturing operation auxiliary devices. One end of the high-pressure manifold is connected to a wellhead connecting pipe; a hollow temporary storage container is arranged at the position, close to the wellhead connecting pipe, of the high-pressure manifold; a feeding box communicated with an inner cavity of the temporary storage container and a corresponding feeding switch are mounted on the temporary storage container; a blow-off pipe and a corresponding blow-off switch are arranged on the temporary storage container; the outlet side of the rear end of the temporary storage container is connected to the high-pressure manifold through a high-pressure connector. A rear-end switch is arranged on the high-voltage connector; the inlet side of the front end of the temporary storage container is detachably connected to an output pipeline of the pump truck through a low-pressure connector and a conveying pipeline. The low-voltage connector is also provided with a front-end switch; the problems that in the prior art, when a temporary plugging material is added in fracturing operation, the temporary plugging material is prone to sedimentation in a high-pressure manifold, and a pump truck is prone to pump clamping, pump burning or liquid leakage are effectively solved.

A stand column type inspection pit structure comprises a base and a plurality of prefabricated stand columns, a plurality of positioning parts are arranged on the upper side of the base at intervals, each prefabricated stand column is vertically connected to the upper side of the base through the corresponding positioning part, and fixing parts are connected to the peripheral faces, close to the upper ends, of the prefabricated stand columns. A first connecting piece is connected between every two adjacent fixing pieces in the length direction of the base, and a second connecting piece is connected between every two adjacent fixing pieces in the width direction of the base. The prefabricated stand columns are adopted for assembly, the site construction period of the stand columns can be effectively shortened, the construction efficiency is improved, and meanwhile the positioning precision of the stand columns can be improved by arranging the positioning pieces; by arranging the fixing pieces and the connecting pieces, the multiple stand columns can be hoisted at the same time, the installation efficiency of the stand columns can be improved, the height and the position of each stand column are adjusted before installation, and therefore the construction precision of the prefabricated stand columns is improved.
