The utility model discloses an asymmetric non -middle wall connected arch tunnel support system relates to tunnel support technical field, including connected arch tunnel first -pass hole initial support, connected arch tunnel first -pass hole initial support includes I20a type steel arch frame, inside phi 8 steel bar net, outside phi 8 steel bar net, steel arch frame connecting reinforcing steel bar, big arch foot reinforcing cage, big arch foot steel arch frame triangle bracing structure, big arch foot steel arch frame connecting steel sheet and stiffened steel plate, through the first -pass hole initial support of setting, first -pass hole initial support adopts I20a type steel arch frame, inside phi 8 steel bar net, outside phi 8 steel bar net, steel arch frame connecting reinforcing steel bar, big arch foot reinforcing cage, big arch foot steel arch frame triangle bracing structure, connecting steel plate and stiffened steel plate, form high -strength, high rigid support system, effectively disperses the surrounding rock pressure, reduces local damage, and system anchor rod and radial injection grouting small catheter consolidate surrounding rock through injection grouting, further enhances the stability of surrounding rock.

This utility model discloses a wind-resistant structure for the crown of a high-rise building, including a mass block disposed inside the crown and steel cables disposed inside the crown, with the mass block suspended inside the steel cables. The mass block consists of an upper part, a middle part, and a lower part. The upper part consists of block A, block B, and block C. Block A is disposed on top of block B, and block C is disposed at the bottom of block B. An installation mechanism is provided at the connection between the top of block B and blocks A and C. By using a modular design, the mass block is divided into relatively small modules, reducing the requirements for manufacturing equipment, manufacturing difficulty, and cost. Compared with the integral type, the modular mass block has a smaller individual module size and weight, which can be transported using ordinary transportation tools, making it easier to cope with road height and weight restrictions, greatly reducing transportation difficulty and cost. At the installation site, the smaller modules are easier to operate and position.

The utility model relates to bridge pier protection technical field, specifically disclose a bridge pier protection structure, include: bridge pier column, the outside both sides of bridge pier column are equipped with arc plate, the outside of two arc plate is equipped with arc crashproof board, the outer arc surface of two arc crashproof board is all ring array and is opened with crashproof groove, and the crashproof groove is arc -shaped, the utility model discloses the synergistic effect of crashproof mechanism and buffer mechanism forms double protection, promotes the anti -impact ability of bridge pier, effectively protects the bridge pier column from direct impact, reduces the ship structure damage simultaneously, realizes the bidirectional protection of bridge pier and ship.

The utility model discloses a raincoat opening buttonhole device relates to raincoat processing technical field. The raincoat opening buttonhole device, including work table, pressing subassembly and opening eye subassembly, work table is fixedly connected with mounting bracket, and pressing subassembly is located in mounting bracket, and pressing subassembly includes sliding rod, moving block, round hole, pull rod, spring, springback and pressing plate, and the number of sliding rod is two groups and is oppositely arranged, and moving block is slidably installed on the sliding rod, and the round hole is formed in moving block and sliding rod, and opening eye subassembly is located above work table. The utility model can carry out pressing work to raincoat, and it is convenient for subsequent work of opening eye, and the setting of pressing can ensure that the buttonhole part of raincoat is more closely attached, avoids the subsequent use of raincoat, appears moisture and penetrates into clothes through the gap of buttonhole, makes the buttonhole place more closely fixed, is helpful to the stability of raincoat in walking, cycling or other activity process.
