The utility model discloses a high-pressure hose pulse static pressure detection device which comprises a C-opening hollow frame, a main liquid inlet transverse cylinder and an auxiliary liquid storage transverse cylinder which are installed on the left outer wall and the right outer wall of the C-opening hollow frame respectively, and hollow pipes installed at the opposite ends of the main liquid inlet transverse cylinder and the auxiliary liquid storage transverse cylinder in a bolting mode through flange plates. A digital display type pressure gauge is installed at the top end of the hollow pipe at the end of the main liquid inlet transverse cylinder, and a hydraulic double-way pump liquid assembly is installed at the top end of the C-opening hollow frame on one side of the main liquid inlet transverse cylinder. Water flow is fed into the main liquid inlet transverse cylinder, the high-pressure hose and the auxiliary liquid storage transverse cylinder through the control panel and the hydraulic two-way pump liquid assembly, the pulse pressure of the high-pressure hose is monitored through the digital display type pressure gauge in the liquid pumping process, and after detection is completed, switching valves at the lower ends of the main liquid inlet transverse cylinder and the auxiliary liquid storage transverse cylinder are opened, and liquid drainage is completed.

This utility model discloses a riverbed steel pipe pile platform for truck crane outrigger foundations, belonging to the field of temporary construction engineering technology. It aims to solve the problems of difficult installation and alignment, low efficiency, and insufficient overall rigidity of existing platforms. A limiting block with a groove is set on the top of the second double-section steel section, which slides in cooperation with the trapezoidal block at the bottom of the roadbed box, achieving rapid self-locking positioning of the roadbed box. A detachable clamping mechanism, consisting of upper and lower clamping plates, threaded columns, nuts, and upper and lower inner support blocks embedded in the internal gaps of the double-section steel section to prevent deformation, is used to clamp and secure the second double-section steel section, binding the parallel steel sections into a high-strength whole, significantly enhancing the platform's bending and torsional resistance. This utility model has the beneficial effects of convenient installation, accurate positioning, stable structure, and strong load-bearing capacity.

This utility model belongs to the field of floor slab reinforcement technology, and in particular to a floor slab structure, including a precast floor slab. Load-bearing walls are provided on both sides of the precast floor slab. An upper reinforcement component is provided above the precast floor slab. The upper reinforcement component includes a formwork and a post-cast concrete layer. The post-cast concrete layer is poured inside the formwork, and a bidirectional steel mesh is provided inside the post-cast concrete layer. Carbon fiber cloth is provided below the precast floor slab. Several transversely evenly distributed main beams are provided below the carbon fiber cloth, and several vertically evenly distributed secondary beams are provided below the transverse main beams. The upper layer combines the post-cast concrete layer and the bidirectional steel mesh to connect the dispersed precast slabs into a whole. The middle layer reinforces the tension zone with carbon fiber cloth, improving the bending load-bearing capacity and ductility of the precast floor slab. The lower layer, with its transverse main beams and longitudinal secondary beams, forms a supporting frame, achieving the effect of improving seismic reinforcement.

The embodiment of the invention discloses a webpage loading method and system and a border gateway. The method comprises the steps that under the condition that a terminal lacks a TCP / IP protocol stack, a terminal browser obtains and encapsulates an HTTP / HTTPS request as a user-defined message frame, and sends the user-defined message frame to a border gateway; and the border gateway obtains the HTTP request message according to the self-defined message frame, obtains a webpage response message of the HTTP request message through an external TCP / IP network, and returns the webpage response message to the terminal to complete webpage loading. The method has the following advantages: (1) under the condition that the terminal lacks a TCP / IP protocol stack, the native browser can still safely and smoothly load the webpage content, and meanwhile, an operating system kernel and an existing security policy are prevented from being changed; and (2) the terminal rendering adapter is responsible for recombining response, recovering DOM and multimedia resources, and cooperating with an integrated session cache and a bidirectional authentication mechanism to ensure interaction security and continuity.

This invention provides a rubber band launching device, comprising: a gun body and a launching system, a feeding system, and a power system for powering the movement of the entire device, all mounted on the gun body. The launching system is mounted on the gun body via a fixed bracket and includes a main shaft, a fixed wheel, a first rocker arm, a rotating wheel, a rubber band hook, and a second drive wheel. The rotating wheel rotates around the fixed wheel and also rotates on its own axis, thereby driving the rubber band hook to perform a pulling and releasing action. The feeding system uses a belt-fed method; when the second drive wheel rotates one revolution, the feed wheel rotates one tooth pitch, thus actuating the belt to feed bullets one by one. This invention features safe loading, simple operation, and prevents finger injuries when installing rubber bands. It can freely switch between single-shot and fully automatic burst modes, and has a large ammunition capacity, allowing for the continuous firing of a large number of rubber bands, enabling players to fully enjoy the fun of shooting and offering high replayability.
