The invention discloses a lithium silicate permeable protective coating composition and a preparation method thereof. The lithium silicate permeable protective coating composition is prepared from 23 wt% of water-soluble lithium silicate, a methyl sodium silicate solution with the concentration of 99 wt%, sodium silicate powder, sodium dodecyl benzene sulfonate, triethylamine, a silane coupling agent KH550 and waterborne epoxy resin E40. According to the invention, metal silicate is used as an inorganic system, waterborne epoxy resin and the like are used as an organic system, the prepared lithium silicate-silane permeable composite protective coating can form a waterproof layer on the surface of concrete to block microcracks of the concrete, and the problem of water seepage of the concrete can be solved.

The invention belongs to the technical field of a coating environment experiment and performance testing equipment and particularly relates to an anti-corrosion coating natural environment test and performance detecting system. The main structure of the system comprises a base No. 1, a base No. 2, a base No. 3, a base No. 4, a control pile, a control unit No. 1, a water pump No. 1, a distilled water tank, a control unit No. 2, a water pump No. 2, an electrochemical workstation, a detection solution tank, a control unit No. 3, a signal receiver, a control unit No. 4, a control cabinet, a chute,a cleaning and drying detector, an electrochemical performance detector, a topography detector, a physical property detector, a curved retractor, a direct connection expansion device and a sample holder. The cleaning and drying detector, the electrochemical performance detector, the topography detector and the physical property detector are combinable spherical double-shell structures. In combination, an overlapping glue strip is overlapped on the edge of the inner casing and the outer casing rotates relative to the inner casing to cover the gap of the overlapping glue strip so that double waterproof sealing effects are obtained.

The invention discloses a sheet pile supporting structure with a water stopping function and a construction method. The sheet pile supporting structure with the water stopping function and the construction method are used for soil blocking and water stopping of the circumferential wall of a foundation pit. The sheet pile supporting structure with the water stopping function comprises sheet piles which are arranged along a positioning line for supporting of the foundation pit at intervals. Grooves are formed in the two side faces of each sheet pile respectively. A concrete splicing plate used for soil blocking and water stopping is arranged between the grooves of every two adjacent sheet piles. The two ends of each concrete splicing plate are embedded into the corresponding grooves. Rubber waterstops used for water prevention are arranged at the joints of the two ends of each concrete splicing plate and the corresponding grooves. According to the sheet pile supporting structure with the water stopping function and the construction method of the sheet pile supporting structure, assembly type construction is adopted, convenience and rapidness are achieved, the concrete splicing plates have the soil blocking and water stopping functions, and the rubber waterstops have the water preventing and sealing functions; the distance between the sheet piles can be properly increased, so that the pile insertion soil squeezing effect is relieved, the integrity of the supporting structure is guaranteed, the rigidity of the supporting structure is effectively improved, and finally the safety and stability of a foundation pit project are achieved; the sheet pile supporting structure is particularly suitable for relatively regular medium and small foundation pit projects.

The invention discloses an internal pressing plate of an energy-saving curtain wall, and relates to the technical field of constructional engineering. The internal pressing plate of the energy-saving curtain wall comprises a lug boss and a base; the width of the lug boss is the same with the size of a gap between glass attached frames so that the gap can be filled with the lug boss; a projection is arranged at an end of the lug boss and is riveted to a thermal-insulation adhesive tape; and a recess is formed in the bottom surface of the base and is connected with a decorative line. By the internal pressing plate of the energy-saving curtain wall, the decorative line can be fixedly connected with an upright column of the curtain wall at the position of a drainage channel, and a certain waterproof sealing effect is achieved. The problem that a curtain wall with a new structure is difficult to assemble is solved.

The invention discloses an intelligent anti-theft device. The intelligent anti-theft device comprises an inspection well which is arranged underground and an inspection well lid used for covering theinspection well. An inspection lid countersunk groove is formed in the periphery of an inspection wellhead of the upper portion of the inspection well. Insertion-clamping grooves extending downwards are symmetrically formed in the left end and the right end of the inspection lid countersunk groove. Locking grooves are formed in the end faces of the inner sides of the insertion-clamping grooves. Pushing grooves communicating with the inspection well are formed in the end faces of the inner sides of the locking grooves. A fixing pipeline is arranged at the position, between the two pushing grooves, in the inspection well. Through cooperation of insertion-clamping blocks and inner ejection springs, the inspection well lid is firmly locked in the inspection lid countersunk groove, automatic locking of the inspection well lid after mounting is achieved, in addition, the inspection well lid can be unlocked by providing power through operation of a driving motor, the production cost is reduced, intelligent control is achieved, the inspection well lid is effectively prevented from being stolen by thieves, moreover, the waterproof sealing effect is effectively achieved through an annular sealing ring and a fixing sealing sleeve, the waterproof protection measures are achieved, and the service life of the intelligent anti-theft device is prolonged.
