Abstract

The present invention belongs to the technical field of rail transit engineering. Provided are a safety evaluation method and system for upper layer-addition construction on an existing underground structure. A thin-layered element method and a sliding wedge theory are used to perform soil pressure calculation on a soil body in three failure modes, so as to obtain a calculation formula for a lateral load on a side wall of an underground structure in each failure mode. In the process, a lateral load on an underground structure at each depth in a corresponding failure mode is given, and a method for calculating a load on a side wall of an existing underground structure during open-cut layer-addition construction is provided. After the lateral load on the underground structure is obtained, safety evaluation can be performed on the structural design of the underground structure on the basis of a calculation result, such that the safety of a lower underground-cut underground structure can be ensured.

Abstract

The present disclosure provides a multi-task deep Hash learning-based retrieval method for massive logistics product images. According to the idea of multi-tasking, Hash codes of a plurality of lengths can be learned simultaneously as high-level image representation. Compared with single-tasking in the prior art, the method overcomes shortcomings such as waste of hardware resources and high time cost caused by model retraining under single-tasking. Compared with the traditional idea of learning a single Hash code as an image representation and using it for retrieval, information association among Hash codes of a plurality of lengths is mined, and the mutual information loss is designed to improve the representational capacity of the Hash codes, which addresses the poor representational capacity of a single Hash code, and thus improves the retrieval performance of Hash codes.

Abstract

The present invention provides a quick-assembly windbreak device for preventing storm damage to a low-rise wooden dwelling. The device comprises a scaffold, multiple windbreak nets, and multiple concrete counterweights. In the present invention, the scaffold is used as a base, and the windbreak nets are tied to the scaffold. Through-holes on the windbreak nets block part of a wind gust while allowing part of the wind gust to pass through, such that a strong wind gust is transformed into a weak wind gust, and so does not apply an impact force or a destructive force to a low-rise wooden house located behind the windbreak nets, thereby achieving good disaster prevention and mitigation and residential house protection effects. The scaffold is widely used and so is easily obtained, and can be erected quickly and easily, and the windbreak nets can also be tied to the scaffold quickly and easily. Erecting a scaffold does not require professional skill, and an ordinary resident can erect a scaffold around their house by themselves, and thus all residents and families can use this device. The device can be quickly disassembled, and can serve as a common family emergency tool. The device has a simple structure and low cost, and is suitable for broad promotion and use.

The protrusions (2) are arranged in multiple columns in the axial direction of the metal pipe (1), and an anti-thrust ramp (3) is formed between adjacent protrusions (2) in the same column, wherein the height of an end of the anti-thrust ramp (3) that is close to the center of the metal pipe (1) is less than that of an end thereof that is away from the center of the metal pipe (1).

Abstract

A method for moving a tall building uphill comprises the following steps: determining a moving start point and a moving end point, digging out the ground from under the building, and exposing a foundation of the building; arranging an inclined linear rail foundation (5) from the moving start point to the moving end point, and laying a steel plate at a top surface of the rail foundation (5); arranging multiple rolling shafts (6) at intervals on the steel plate below the building and corresponding thereto; arranging, at a top portion of the rolling shafts (6), steel channels parallel to an extending direction of the rail foundation (5), and pouring concrete to form underpinning beams (7), wherein the underpinning beams (7) are connected to rebars pre-embedded into vertical pillars of the building and fixedly connected to the building as an integrated piece; cutting connections between the vertical pillars and the foundation of the building; and arranging a drive mechanism at a terminal portion of the rail foundation (5), and driving the building to move from the moving start point to the moving end point. The method for moving is safe and reliable, and prevents buildings from leaning and creating additional internal stress which causes structural damage.

Abstract

A displacement inclination rectification method for a building, comprising the following steps: determining a row of framework columns (3) having the minimum settlement amount, and acquiring a settlement difference between another row of framework columns (3) and said row of framework columns (3); digging a foundation, exposing former site bases (1, 2), and arranging new site bases (6); uniformly distributing inclined linear displacement tracks (7, 8) along a displacement direction; arranging a roller (9) and a steel channel on each of the displacement tracks (7, 8), and pouring concrete into the steel channels to form underpinning beams (10, 11), the underpinning beams (10, 11) being fixedly connected as a whole by means of a linking beam (12); horizontally driving sliding blocks by a drive mechanism so as to drive the framework columns (3) to move along the displacement tracks (7, 8) up to a displacement endpoint; and completing the inclination rectification when all the framework columns (3) are at the same horizontal height. The inclination rectification method is safer and better protects a building structure.

Abstract

The present invention provides an anaerobic-AO-SACR combined type advanced nitrogen removal system and process for high-ammonia-nitrogen sewage. The high-ammonia-nitrogen sewage firstly enters an anaerobic reactor for removal of most organic matters in the sewage; the effluent from the anaerobic reactor enters an AO reactor for pre-denitrification nitrogen removal in an anoxic zone and residual organic matter removal and ammonia nitrogen nitrification in an aerobic zone; the effluent from the AO reactor enters an intermediate water tank, and by means of control of a water quality testing device and a PLC controller, part of raw water is introduced into the intermediate water tank for adjustment of the carbon-nitrogen ratio of the sewage; then, the effluent from the intermediate water tank enters an SACR reactor, and by means of the characteristics of denitrifying bacteria as well as regulation and control of a PH/DO/ORP tester and the PLC controller on the SACR reactor, the sewage is accurately subjected to pre-denitrification-nitrification-endogenous denitrification for deep denitrification. No additional carbon source is needed, and process costs are low. Moreover, for built sewage treatment facilities using an AO process, the process in the technical solution can be implemented only by adding the intermediate water tank and the SACR reactor, and upgrading and reconstruction costs are low.

Abstract

Disclosed is a Fe-based alloy powder for argon arc overlay welding, the powder consisting of Fe-Cr, graphite, and iron powder. A process for preparing the Fe-based alloy powder for argon arc overlay welding comprises: uniformly mixing Fe-Cr, graphite, and iron powder according to a certain ratio, and preparing same into flakes with sodium silicate as a binder; the flakes are naturally dried for 10 h and then placed in a drying oven and dried at 200°C for 1.5 h, and oven cooled. With a tungsten electrode argon arc as a heat source, the obtained substance is overlay welded on the surface of a material to form a wear- and corrosion-resistant molten cladding layer. The molten cladding layer has a uniform texture, and can generate new phases such as chromium-carbon compounds; the deposit welded layer has a hardness greater than HRC55 and can effectively improve material performances such as wear-, corrosion-, and high temperature-resistance, so as to extend the service life of parts. In addition, the Fe-based alloy powder for argon arc overlay welding is simple to prepare, low in cost, and thus has a relatively high use value.
