The utility model relates to the technical field of pipelines, in particular to an ultrapure water system pipeline structure which comprises a main pipeline, a horse mouth connecting hole is formed in the side wall of the main pipeline, a welding saddle is installed at the position of a port of the horse mouth connecting hole, and a valve is arranged at one end of the welding saddle. According to the utility model, the horse mouth connecting hole is formed in the outer wall of the main pipeline to replace a tee joint, the saddle processing piece is processed according to different pipeline specifications, the radian of the processing piece for welding the saddle is consistent with the radian of the outer wall of the corresponding different main pipeline, and the processing piece and the pipeline wall are simultaneously heated by using the arc-shaped infrared heating ironing plate; then a clamp is adopted for clamping a machined part welding saddle and a main pipeline, it is guaranteed that the machined part welding saddle and the main pipeline are tightly attached, after the machined part welding saddle and the main pipeline are completely cooled, a proper tapper is used for tapping, a vacuum dust collector is started at the same time, it is guaranteed that chippings are sucked away in time, a chamfering device is used for chamfering an arc at the joint of the welding saddle and the main pipeline after tapping is completed, and dead corners are avoided; and the practicability is better.

The invention discloses a foundation pit engineering steel truss support and concrete support combined system servo system and a construction technology, and relates to the technical field of deep foundation pit engineering.The foundation pit engineering steel truss support and concrete support combined system servo system comprises an enclosure structure, the enclosure structure is buried around a foundation pit, the outer side face of the enclosure structure abuts against a soil body of the foundation pit, and an initial support is installed between the opposite faces of the top of the enclosure structure; the inner side faces of the enclosure structures abut against the foundation pit combined supporting system. The foundation pit combined supporting system comprises a steel truss supporting system and a concrete supporting system, the concrete supporting system is installed in the middle of a foundation pit, the two ends of the concrete supporting system are fixedly connected with the steel truss supporting system, and the steel truss supporting system abuts against the inner side face of the enclosure structure through steel enclosing purlins. And a prestress loading unit is arranged between the opposite surfaces of the steel truss supporting system and the steel enclosing purlin. According to the foundation pit engineering steel truss support and concrete support combined system servo system and the construction technology, construction is convenient, the construction period is short, and the cost is low.

The utility model discloses a basement retaining wall structure and a basement structure, and belongs to the field of buildings, in order to solve the problem that in the prior art, the construction period for building side walls and supporting and retaining structures of basement walls is long, the basement retaining wall structure comprises a wall body (6), a buttress (14), a wall toe (3), a wall heel (1) and an anti-skid key (2), the buttress (14) is connected with the wall body (6) and the wall heel (1), and the anti-skid key (2) is connected with the buttress (14). The wall heel (1) and the anti-skid key (2) are connected up and down, the anti-skid key (2) is of a strip-shaped structure, and the extending direction of the anti-skid key (2) is the same as that of the wall body (6). The basement retaining wall structure not only can be used as a basement outer side wall to play a permanent retaining role, but also can ensure the backfill operation of a retaining area and the construction of other structures of the backfill area while ensuring the normal construction of the basement, and does not need to construct a basement side wall and a retaining structure at the same time, so that the construction period is shortened, and the construction cost is reduced. And the construction cost is also saved.

An assembled corridor has two rows of alternate foundation bodies, the foundation bodies support columns, the columns support a roof, the middle of the foundation body has an upward open column anchoring hole, the lower end of the column is adaptively inserted into the column anchoring hole, the roof is composed of a bottom roof bottom surface and two side inward inclined roof surfaces, the cross section is approximately triangular, a hollow part in the middle forms a corridor hole, the top intersection of the two roof surfaces is provided with a roof ridge, the roof bottom surface is provided with a column anchoring hole, the top of the column is provided with a roof connecting boss, the roof connecting boss is inserted into the column anchoring hole, the upper and lower parts of the column are correspondingly provided with a connecting beam anchoring point and a stool plate anchoring point, the connecting beam anchoring points of adjacent columns are connected with a connecting beam, and the stool plate anchoring points of adjacent columns are connected with a stool plate. The foundation body, the column, the connecting beam, the stool plate and the roof are processed in the factory, are transported to the site for assembly, can accelerate the construction period, and are convenient for later removal and reuse.
