The invention discloses a composite flexible support integrated construction method for building deep foundation pit engineering, and belongs to the technical field of foundation pit support. The construction method comprises the following steps: rapidly spray concrete on the repaired slope, and seal the foundation pit slope in time; after the concrete is solidified, drill holes, inject cement slurry into the anchor hole, and insert the anchor rod; The prefabricated steel wire mesh frame is installed on the slope of the foundation pit, and the two adjacent steel wire mesh frames are connected to the end of the anchor rod through the connecting component. The bottom of each steel mesh frame frame is reserved with an insertion end, and the insertion end is inserted in the construction during construction. The bottom of the foundation pit; secondary shotcrete on the installed prefabricated wire mesh frame. In the present invention, the steel wire frame for support, the elastic filler for buffering, the bolt for reinforcement and shotcrete together constitute a composite flexible support system, which greatly changes the support effect, and the prefabricated components make construction convenient , efficient.

In a shielding structure of a shielding electric wire in which the shielding electric wire and a ground wire are interposed between two resin members, and a compressive force is caused to act on the resin members and an ultrasonic wave is simultaneously applied to fuse the resin portions, thereby forming a shielded portion, a protruded portion 20 is provided on one of junction faces of the two resin members and a hole 21 including a protrusion inserting portion 21a for inserting the protruded portion 20 and a resin inflow portion 21b provided in an inner position from the protrusion inserting portion 21a and having a smaller width than a width of the protrusion inserting portion 21a is provided on the other junction face, and step faces at both sides on a boundary between the protrusion inserting portion 21a and the resin inflow portion 21b in the hole 21 are formed to be a pair of inclined faces 21c and 21c.

The invention discloses a composite power underwater glider using battery electric energy and ocean temperature difference energy. The main part of the composite power underwater glider is composed of the main body of the composite power underwater glider, and the cabin section is fixed in sequence along the axis of rotation of the cylinder. The heat exchanger is hung on the belly of the main body, and the horizontal wings are arranged horizontally on both sides of the rear pressure cabin. The battery pack of the composite power underwater glider has two degrees of freedom of translation and rotation, and can adjust the pitch angle and heading angle of the underwater glider. The hydraulic components and the heat exchanger in the main body constitute the hydraulic oil circuit. During the diving preparation stage of the composite power underwater glider, the oil return circuit works; during the diving gliding stage, the solidification oil circuit works; The pumping oil circuit works; in the floating gliding stage, the energy storage oil circuit works to realize the buoyancy driving process by combining energy in the form of battery electric energy and ocean temperature difference energy.

The invention relates to a shelter of an emergency communication command vehicle, relating to an emergency communication command shelter and aiming at solving the following problems that an existing emergency communication command vehicle is easily influenced by the factors, such as roads and environments, because the vehicle is used as a transport carrier, and in addition, the holding force is poor because running guarantee is excessively provided by the vehicle as the carrier. The shelter of the emergency communication command vehicle, which is disclosed by the invention, comprises a box body, a communication part, a power supply guarantee part, a control part and a logistical guarantee part; the box body is divided into a control cabin and an equipment cabin; a field commander control table, a living guarantee area, a logistical guarantee area, a power supply and distribution area, a flight control operation table and a communication network area are arranged in the control cabin; a communication signal of a communication antenna passes through a front cable window or a rear cable window arranged on the box body through a communication antenna feeder and is connected with the communication signal input / output end of a communicator in the box body; power is supplied to the communication part, the power supply guarantee part, the control part and the logistical guarantee part by a power supply battery pack. The shelter of the emergency communication command vehicle, which is disclosed by the invention, is applied to emergency communication command under all kinds of severe working conditions.

The invention discloses a bacteria filter for urban rainwater collecting. A filtering medium layer is mounted in a bacteria filter body; a transition medium layer supporting the filtering medium layer is arranged under the filtering medium layer; a compost covering layer covers the upper surface of the filtering medium layer; plants are grown on the compost covering layer; a water drain pipe for draining treated rainwater is arranged at the lower part of the bacteria filter body; an overflow pipe enabling untreated rainwater to overflow is arranged at the upper part of the bacteria filter body; and a rainwater retention zone is arranged above the transition medium layer in the bacteria filter body. The bacteria filter is reasonable in structure, can treat and collect rainwater, provides a large amount of high-purity water sources to be selectively used in cities, and meanwhile, solves the urban environment problem caused by storms. Viewed from the ecology, the bacteria filter for urban rainwater collecting can serve as or replace existing urban greening well, and has the characteristics of environment friendliness and strong compatibility.

The invention discloses a variable-configuration dual-navigation long-range marine unmanned vehicle driven by a natural environment fluid, which has a surface navigation mode, a navigation switching mode and an underwater navigation mode, and includes: a wind energy collection unit that receives wind applied by ocean wind. The aerodynamic force drives the aircraft to sail; the buoyancy adjustment unit adjusts the buoyancy of the aircraft itself in the underwater navigation mode, and combines the hydrodynamic force exerted by the head-on water flow when the aircraft moves to realize the heave movement and horizontal travel of the aircraft; wing keel; linkage The unit is used to complete the pose change of the sail and the wing keel during the navigation switching mode; the photovoltaic power generation unit is used to collect solar energy and provide power supply for the aircraft's power consumption devices during the surface navigation mode. The variable-configuration dual-navigation state long-range marine unmanned vehicle driven by the natural environment fluid provided by the present invention utilizes the sea surface wind and air flow, underwater water flow and sunlight in the natural environment to achieve energy self-sufficiency. It is capable of long-distance navigation in all navigation states.

The invention discloses a composite flexible support integrated support system for building deep foundation pit engineering, which belongs to the field of composite flexible support for building deep foundation pits. After pretreatment, anchoring can effectively improve the firmness of the anchor rod and the inside of the foundation pit, and the use of steel mesh frame can effectively cover and support the deep foundation pit slope in time, and effectively absorb the generation of slope displacement. The dynamic stress of the deep foundation pit has the effect of supporting and buffering. The anchor rod and the deep foundation pit slope protection are integrated to bear the elastic strain, and the self-bearing capacity of the deep foundation pit slope is improved. The elastic filler for buffering effect, the anchor rod for reinforcement effect and shotcrete are composed The composite flexible support system greatly changes the support effect, and the prefabricated components make the construction convenient and efficient.
