The invention relates to a prefabricating, floating transporting and fitting-out technology for steel shell immersed tunnel pipe sections and belongs to the technical field of marine traffic engineering construction in transportation. The technology includes the following steps that steel shells of the tunnel pipe sections are manufactured on land, and the manufactured steel shells are transported to a concrete pouring and fitting-out quay at the tunnel address in a floating manner; concrete pouring and fitting-out part installation are conducted on the steel shells on the concrete pouring and fitting-out quay, and the tunnel pipe sections are manufactured; and the manufactured tunnel pipe sections are transported to a sinking position to be sunk and installed. According to the technology, due to the fact that the tunnel pipe sections are fitted out and wait to be installed at the position of the construction tunnel address, selection of operation windows for sinking and installing is very convenient, meanwhile, the number of the operation windows is increased, and the construction efficiency and the safety guarantee rate of construction are improved.

The invention mainly relates to the technical field of textile and discloses firefighter uniform fabric. The firefighter uniform fabric is prepared from meta-aramid, spandex, dacron, polynosic, medical stone functional fiber, sepiolite fiber, bamboo charcoal fiber, titanium dioxide and white carbon black. The firefighter uniform fabric has the advantages of rich raw materials and simple method, the obtained firefighter uniform fabric conforms to technical indexes of 'fire fighting protective clothing', perspiration permeability of the fabric is achieved, weight of each suit of firefighter uniform is reduced by around 40%, and burden of firefighters in fire relief is obviously alleviated; the spandex is deformed by adding the titanium dioxide, strength and heat-resistance temperature of the spandex are increased, solidification is fastened during spinning, sweat and heat dissipation is fastened since the cross section is hollow-ring shaped, and uniform weight is reduced; the white carbon black and the dacron are subjected to vacuum melting prior to deforming, discloloring of the dacron after melting is avoided, heat-resistance temperature and fiber strength of the dacron are improved, the cross section of the dacron is cross shaped, porosity in the fiber after blending can be increased, and sweat and heat dissipation are fastened.

The invention provides an electronic ticket producing method and system and a device. The method includes the following steps: receiving an electronic ticket buying request, and launching a payment application after checking that state information in electronic ticket attribute information carried by the buying request is valid; and receiving a payment finishing request, binding a ticket number stored in a database corresponding to the electronic ticket attribute information carried by the payment finishing request with a user terminal ID carried by the payment finishing request, creating a check code of the ticket number that is bound; associating the bound ticket number with the check code and encrypting the ticket number, and producing and sending encrypted electronic ticket information. The method also includes the steps of forming a second cryptograph after conducting secondary encryption on the received encrypted electronic ticket information and then storing the electronic ticket information. The technical scheme of the invention solves the technical problem about data security of conventional two-dimensional code electronic tickets, and further improves the data security rate of two-dimensional code electronic tickets.

The invention provides an electronic ticket donation method, system and device. The electronic ticket donation method comprises the steps that an electronic ticket donation request sent by a first user terminal is received, first user terminal attribute information carried by the donation request is checked and is bound with electronic ticket information, the state information in electronic ticket attribute information is effective, and after it is queried that a first checking code matched with an electronic ticket is same as a first checking code stored on the first user terminal, a target application is donated; the effective second user terminal attribute information sent by the first user terminal is received, answering information about donation agreement of a second user terminal is received, the first checking code is invalid, encryption is performed after a bound ticket number is relevant with the second checking code, and encrypted electronic ticket information is generated and sent to the second user terminal. The technical problem of donation data safety of existing two-dimensional code is solved, dynamic two-dimensional codes of original possessors can be invalid when electronic ticket possessors are changed, and the benefits of persons receiving donation are protected.

The invention discloses a pedestrian collision avoidance system and method based on vehicle-road coordination. The system includes a vehicle-mounted module, a roadside module, a vehicle-road communication module, a central processing module, and a display and control module. The information interaction between the roadside module and the vehicle-mounted module is carried out through the vehicle-road communication module, and the data of the two are sent to the central processing module together. The central processing module fuses and processes the multi-source information, and sends instructions to the display and control module to perform anti-collision measure. The invention obtains wider and more accurate pedestrian information by means of vehicle-road coordination, determines the collision risk of pedestrians and vehicles, and then takes corresponding anti-collision measures to achieve the purpose of safe and intelligent assisted driving.

The invention relates to the field of flood prevention and rescue of the Yellow River, in particular to a method for building a depth-limited temporary bridge for emergency rescue. According to the method, a temporary bridge for emergency rescue is built by the aid of a portable bridge cage emergency rescue device, when legs of the temporary bridge are installed, bridge leg depth limiting devicesare directly clamped at reserved positions of the bridge legs, and then the temporary bridge is used for carrying out throwing operation. According to the method, the devices building the temporary bridge can be quickly assembled on site, a cage-based-leg temporary bridge is built at the position of a breach, the bridge leg depth limiting devices are utilized to solve the problems that load bearing capacity of the rapidly-built temporary bridge is low and the bridge is prone to inclination and stability loss, effective repair can be carried out timely when a dam is burst, the temporary bridgetransportation is convenient and fast, the construction steps are simple, and the application range is wide.
