The invention provides a gap-adjustable, quick non-penetrating installation roller blind, comprising a roller blind mechanism and a fixing mechanism. The fixing mechanism is supported between supporting walls and includes a non-penetrating installation mechanism and a supporting rail. A groove is provided at the lower end of the supporting rail. The roller blind mechanism is installed below the supporting rail, with a slider provided at the upper end of the roller blind mechanism. The roller blind mechanism achieves sliding relative to the supporting rail through the cooperation between the slider and the groove, and the slider and the groove prevent free sliding through interference fit or spring piece design. The invention allows the relative adjustment of the position of the curtain fabric after installation, ensuring even gaps on both sides and stable positioning of the curtain fabric by avoiding free sliding of the slider and the groove.

This application relates to the field of building construction, and in particular to an adjustable diagonal bracing device for supporting wall formwork. It includes a main adjusting rod, comprising a first adjusting rod and a second adjusting rod. The second adjusting rod has an axially arranged slide rail, and the first adjusting rod is slidably connected within the slide rail. The first adjusting rod has several limiting holes arranged along its extension direction. A connecting member is inserted into the limiting holes, limiting the position of the first adjusting rod within the slide rail. An adjusting nut is threaded onto the end of the second adjusting rod that is inserted with the first adjusting rod, providing support force to the connecting member and adjusting the position of the first adjusting rod within the slide rail. An elastic indicator is disposed between the connecting member and the adjusting nut, indicating the preload between the adjusting nut and the connecting member. Connecting buckles are disposed at both ends of the main adjusting rod for connecting and fixing to the wall formwork support. This application enables rapid and precise installation of the diagonal bracing and adjustment of the verticality of the wall formwork, with a simple structure and safe operation.

The utility model relates to a steel structure assembly type wallboard support which effectively solves the problems that an existing assembly mode cannot well guarantee that a wallboard is in a proper state, operation is complex, an existing wallboard support is not suitable for wallboards with different widths, and production cost is increased. According to the steel structure assembly type wallboard support, through the arrangement of the rear supporting plates, the cross-type telescopic frame, the cross-shaped sliding frame and the supporting assembly, a constructor can adjust the cross-type telescopic frame according to the width of a wallboard, so that the distance between the rear supporting plates is adjusted, and the width of the wallboard support is matched with the wallboard needing to be installed; wallboards with different widths can be conveniently supported, the applicability of the bracket is improved, and the cost is reduced; the threaded rod is driven to rotate by rotating the rotating grip, so that the multiple supporting assemblies are ejected outwards by the same distance, it can be guaranteed that the wall plate is always in a vertical state during installation and can be firmly installed, the installation accuracy of the wall plate is improved, and the firmness of the whole building is guaranteed.

The invention relates to the technical field of foundation pit supporting, in particular to a river-facing deep foundation pit construction method which comprises the following steps: S1, radar detection outside a foundation pit; s2, the stand column piles and the steel pipe piles are installed; s3, the outer side of the supporting wall is subjected to grouting reinforcement treatment; s4, excavation of a foundation pit; s5, construction of a first concrete support; s6, an inner supporting lifting frame is manufactured; s7, construction of a second concrete support; s8, mounting a support in the steel pipe; and S9, blocking the support wall. According to the construction method, through an engaged pile body structure of the supporting wall, accurate grouting reinforcement based on radar detection on the outer side of the supporting wall, curtain formation, layered excavation of a foundation pit, multi-channel inner supporting of the supporting wall, inner supporting lifting frame and sectional type formwork pouring, the purposes of improving the anti-seepage performance, safety and reliability in the construction process are achieved; the overall stability of the supporting system is improved, and the effect of saving materials is achieved.

The invention provides a cross construction method for a close shield tunnel and a foundation pit, and relates to the technical field of municipal engineering construction. The method comprises the steps that support walls are arranged on the two sides of a target foundation pit area and located between two shield tunnel areas; then, the target foundation pit area is excavated to the initial design depth, and an initial foundation pit is formed; a second supporting mechanism used for abutting against the supporting wall is arranged in the initial foundation pit, and then shield tunnel crossing construction is conducted on the shield tunnel area on one side; after construction of the shield tunnel on the side is completed, a supporting structure is arranged in the shield tunnel; then, the initial foundation pit is excavated to the target design depth, a target foundation pit is formed, and a third supporting mechanism abutting against the supporting wall is arranged; the lengths of the second supporting mechanism and the third supporting mechanism in the direction between the supporting walls can be adjusted; and shield tunnel crossing construction is conducted on the shield tunnel area on the remaining side. On the premise of guaranteeing construction safety and reliability, construction efficiency can be improved, and the construction period can be optimized.

The utility model relates to the technical field of fire hydrant box doors, in particular to a combined type fire hydrant box door structure which comprises a middle supporting wall body, the middle supporting wall body is used for partitioning a space, and a door lower frame is installed on the front side of the middle supporting wall body. The top of the fourth door frame and the bottom of the second door frame are kept consistent, so that the overall attractiveness and coordination of the fire hydrant box door are guaranteed; the lower side of the lower door frame is matched with the third door frame on the upper side, the lower door frame and the third door frame on the upper side are in left-right alignment during splicing and then are overlapped together to be directly welded on the inner side, and the third door frame, the lower door frame and the second door frame form a closed cavity after welding is completed, so that the connecting strength can be greatly enhanced; the fire hydrant door frame assembly and the fireproof door frame assembly are spliced in a split manner, so that the fire hydrant door frame assembly and the fireproof door frame assembly are easy to manufacture and splice, the quality of the whole spliced fire hydrant door frame assembly and the fireproof door frame assembly is ensured, and the combined fire hydrant door is convenient to use.
