The invention provides a prefabricated part combined enclosing wall and an installing method thereof. The prefabricated part combined enclosing wall comprises a foundation, columns, column caps, bottom beams, wall boards and wall caps. Column foot connecting parts of the lower portions of the columns are inserted and connected to prefabricated bolts of foundation prefabricated parts and are fastened. Bottom beam tenons at two ends of each bottom beam are respectively inserted and connected into column holes formed in the lower portions of the left and right columns. Wall board grooves formed in the left and right sides of the wall boards are respectively inserted into column convex ribs of the left and right columns, and the wall board convex ribs at the lower portions of the wall boards are inserted into the bottom beam grooves formed in the bottom beams. Wall cap tenons at two ends of each wall cap are respectively inserted into the column holes formed in the upper portions of the left and right columns, and the wall cap grooves formed in the lower portions of the wall caps are inserted into the wall board convex ribs at the upper portions of the wall boards. The column caps are buckled at the tops of the columns, and the tops of the columns are inserted into the column cap grooves of the lower portion of the column caps. The prefabricated part combined enclosing wall is assembled by adopting a prefabricated part splicing method, is high in construction efficiency, strong in wind-resistant capability, attractive and durable and can be repeatedly used as required.

The invention relates to the technical field of steel structure houses and public buildings, in particular to a steel-concrete combined special-shaped lattice column. The combined special-shaped lattice column provided by the present invention is composed of square steel pipe concrete column, channel steel, and strips. There are two structural types, namely type I and type II, and each has three cross-sectional forms, which are "L" type , "T" and "Ten" shapes; Bolt-assembled K-shaped strips are used for connection. The present invention overcomes the problems of inflexible structural arrangement, difficulty in factory prefabrication of components and low degree of standardization of components in the prior art, and most of the components used can be prefabricated in the factory. Prefabricated autoclaved blocks form an "intelligent" combined special-shaped lattice column integrating structure, heat preservation and sound insulation.

The invention relates to a demounting and mounting method and a demounting and mounting tool, in particular to a special tool and method for demounting and mounting of a high-pressure self-sealing manhole. The special tool comprises a chain block, a cross beam used for fixing the chain block and a stand column used for supporting the cross beam. The special tool is characterized in that a locating pin matched with a bolt hole, for fixing a four-element ring, in the circumference of the manhole is fixed to one end of the cross beam; a sleeve is fixed to the upper end of the stand column used for supporting the cross beam; the chain block is mounted on the cross beam through a pulley set; a thread matched with a threaded hole, for mounting of a lifting screw, in a manhole sealing cover is arranged at one end of a take-out rod; and a lifting ring matched with chain block is fixed to the middle of the take-out rod. The demounting and mounting tool and method have the beneficial effects of being simple in structure, convenient to use, high in demounting and mounting efficiency, good in safety and the like and are especially suitable for demounting and mounting of the inner-sealing high-pressure container manhole.

The invention discloses a movable drilling cabin for ice-rock core drilling of a polar region. The movable drilling cabin comprises a drilling tower, a heat-insulation wall body and sleigh ride in-cabin equipment. The movable drilling cabin provided by the invention integrates drilling equipment including a winch, the drilling tower, a control table and the like, so that efficient ice core drilling and rock core drilling can be realized, and ice cores and rock cores are collected. The movable drilling cabin has the characteristics of rapidness in installation and convenience for transportation in the Antarctic Pole.

The invention discloses a portable load-bearing support frame. The portable load-bearing support frame comprises a square base, support plates, movable transverse rods and movable diagonal rods, wherein each support plate is formed by welding two support rods and fixed transverse rods and fixed diagonal rods distributed between the support rods; connecting plates provided with pin holes are welded on the support rods; brace rod seats provided with mounting grooves and pin holes are welded on the four top corners on one side or both sides of the square base; mounting plates provided with pin holes are welded at the two ends of each support rod respectively; the two support plates are arranged on the four brace rod seats of the square base; the movable transverse rods and the movable diagonal rods are arranged on the connecting plates between two corresponding support rods through pins or bolts. The huge-size load-bearing support frame fixedly into a whole is transported or stored by being disassembled into parts, thereby greatly increasing the transport efficiency and reducing the storage area. The portable load-bearing support frame has the advantages of high field assembly field, flexibility in adjusting the mounting height as required, and the like, and is a load-bearing support frame which is more consistent with the construction requirement.

The invention provides a prefabricated part combined enclosing wall and an installing method thereof. The prefabricated part combined enclosing wall comprises a foundation, columns, column caps, bottom beams, wall boards and wall caps. Column foot connecting parts of the lower portions of the columns are inserted and connected to prefabricated bolts of foundation prefabricated parts and are fastened. Bottom beam tenons at two ends of each bottom beam are respectively inserted and connected into column holes formed in the lower portions of the left and right columns. Wall board grooves formed in the left and right sides of the wall boards are respectively inserted into column convex ribs of the left and right columns, and the wall board convex ribs at the lower portions of the wall boards are inserted into the bottom beam grooves formed in the bottom beams. Wall cap tenons at two ends of each wall cap are respectively inserted into the column holes formed in the upper portions of the left and right columns, and the wall cap grooves formed in the lower portions of the wall caps are inserted into the wall board convex ribs at the upper portions of the wall boards. The column caps are buckled at the tops of the columns, and the tops of the columns are inserted into the column cap grooves of the lower portion of the column caps. The prefabricated part combined enclosing wall is assembled by adopting a prefabricated part splicing method, is high in construction efficiency, strong in wind-resistant capability, attractive and durable and can be repeatedly used as required.
