The invention relates to a construction method of a foundation pit concrete inner support post-dismantling structure. The construction method comprises the following steps that firstly, construction preparation is conducted; secondly, an inner supporting cushion layer is poured; thirdly, inner supporting beam steel bars and water stop steel plates are installed; fourthly, basement outer wall vertical steel bars and basement outer wall horizontal steel bars are pre-buried; fifthly, an inner supporting beam formwork is installed; sixthly, inner supporting beam concrete is poured; seventhly, construction is conducted below an inner support; eighthly, basement outer wall horizontal steel bars and basement outer wall vertical steel bars are connected; ninthly, a basement outer wall structure is constructed; and tenthly, the inner support is dismantled. According to the post-dismantling construction method for the inner support of the deep foundation pit, construction is convenient, the connection stress problem of the horizontal steel bars and the vertical steel bars of the outer wall of the basement can be solved, and the waterproof and anti-seepage problems of the post-dismantling inner support can also be solved.

The invention relates to the technical field of road construction, and particularly discloses an assembly type fence inner side anti-overflow base and a construction method thereof.The assembly type fence inner side anti-overflow base comprises multiple stop blocks, the bottom ends of the stop blocks are used for being buried in a concrete pavement, the stop blocks abut against one another, one side of each stop block is fixedly connected with a positioning block, and the other side of each stop block abuts against the corresponding positioning block; a positioning groove is formed in the other side of each stopping block and used for containing the positioning block on the adjacent stopping block, and a chiseling-free grout stopping belt is arranged at the bottom end of each stopping block and used for being buried in a concrete pavement. The construction process can be simplified, and the construction period can be shortened; the stop blocks are arranged in a separated mode, so that follow-up dismantling is facilitated, the stop blocks can be repeatedly used after being dismantled, the utilization rate of materials is increased, and cost is reduced; and the supporting mechanism is used for supporting the pre-embedded block, so that the anti-overflow base can still have a good water retaining effect when being installed on an uneven road surface, and the applicability is higher.

This invention discloses a shape control structure for thin-walled cavity parts made of titanium alloy based on laser additive manufacturing, its design method, and its application. The design scheme includes the following steps: modeling the shape control structure of the cavity part in 3D modeling software for additive manufacturing; then constructing a solid volume block with an inner wall adapted to the shape control structure within the cavity part shape control structure; further dividing the solid volume block into multiple discontinuous thin blocks of the same thickness and spacing; and importing the thin blocks and the cavity part shape control structure into 3D printing software. The structure constructed through this design method can more easily realize the generation of multi-scenario supports, break through the constraints of support structures, and can also exist as a shape control structure in the manufactured parts. Furthermore, while meeting the requirements for controlling the deformation of the parts, it also makes the supports easy to remove, effectively improving the manufacturing quality and production efficiency of the parts.

The utility model discloses a stainless steel corrugated pipe assembly which comprises a corrugated pipe and a connecting mechanism. A first connector and a second connector are rotationally arranged at the two ends of the corrugated pipe correspondingly. The connecting mechanism is installed between the pair of corrugated pipes and comprises a connecting piece, a first threaded head and a second threaded head are fixed to the two sides of the connecting piece correspondingly and connected with the first connecting head and the second connecting head correspondingly in a matched mode, grooves are formed in the multiple side edges of the connecting piece correspondingly, fixing shafts are fixed in the grooves correspondingly, and the fixing shafts are connected with the first connecting head and the second connecting head correspondingly. Clamping plates are rotationally arranged on the multiple fixing shafts, sliding grooves are formed in the clamping plates, the fixing shafts slide in the sliding grooves, control heads are fixed to the ends, away from the sliding grooves, of the multiple clamping plates, limiting blocks are fixed to the two side walls of the groove, and limiting grooves matched with the limiting blocks are formed in the two side walls of the clamping plates. According to the utility model, through related structural design, quick connection among multiple sections of corrugated pipes can be realized, and later dismounting is facilitated.

This utility model relates to a green installation structure for ICU ward walls, including a mounting base plate and a medical cleanroom panel. The mounting base plate is installed on the main surface of the ICU ward wall using threaded fasteners. The front of the mounting base plate has multiple evenly distributed insertion rings, and the back of the medical cleanroom panel has several evenly distributed receiving slots. The insertion rings are inserted into the receiving slots to install the medical cleanroom panel on the front of the mounting base plate. The advantages are: using threaded fasteners to install the mounting base plate on the main surface of the ICU ward wall, and using insertion rings to install the medical cleanroom panel on the front of the mounting base plate, facilitates the installation of the medical cleanroom panel, reduces the use of adhesive, reduces the release of polluting gases from the adhesive later, eliminates the need for support devices, and facilitates later removal or replacement; when the wall surface is uneven, leveling pads are installed to support and level the mounting base plate, eliminating the need for mortar leveling.
