The invention relates to a modular assembly type high fill retaining wall, and relates to the technical field of ecological protection, the modular assembly type high fill retaining wall comprises a high fill soil body and a retaining wall body formed by splicing a plurality of precast concrete modules, and the retaining wall body formed by splicing the plurality of precast concrete modules is laid on the left side of the high fill soil body; a three-stage drainage mechanism is integrated on the retaining wall body. According to the modular assembly type high-fill retaining wall, a three-stage drainage mechanism composed of the first-stage earth surface water interception assembly, the second-stage wall back collecting and drainage assembly and the third-stage wall body guiding-out assembly is integrated in the retaining wall body, and a complete hydrological regulation and control path from slope top runoff interception, wall back seepage filtration and collection to directional guiding and drainage in the wall body is constructed. Wherein the seepage regulation and control layer effectively prevents fine particles of a high-filled soil body from losing, the confluence channel and the guide and discharge pipe gallery arranged with the gradient cooperate to achieve efficient one-way water flow discharge, the hydrostatic pressure behind the wall and the height of the infiltration line are remarkably reduced, and the problems that drainage holes of a traditional assembly type retaining wall are prone to being blocked and difficult to maintain are solved.

The present application belongs to the technical field of composite pipe, and particularly relates to a steel wire mesh skeleton composite pipe for hot water transportation and a preparation method. The pipe comprises, from inside to outside, an inner lining heat-resistant layer, a composite reinforcing layer and an outer coating layer. The inner lining heat-resistant layer is mixed with a heat-conducting filler, the composite reinforcing layer adopts a gradient density integrated welded metal wire mesh skeleton, and is matched with a modulus 50MPa-150MPa thermoplastic elastomer stress decoupling layer containing heat-sensitive microcapsules, and the outer coating layer contains closed cell microbeads. In the preparation, the gradient woven welded skeleton is prepared, the microcapsules are pre-fixed in the shielding area after surface activation, and then the inner and outer layer materials are synchronously co-extruded and compounded and gradient cooled and shaped. The present application relieves the interlayer thermal stress through the stress decoupling layer, guarantees the microcapsules intact to realize high-temperature self-repairing through the shielding area, reduces the heat loss through the "inner heat conduction and outer insulation" structure, solves the problems of traditional pipe, such as high-temperature delamination, steel wire slip and heat bridge heat dissipation, and improves the stability and service life under high-temperature working conditions.

The invention relates to laminated glass and a product. The laminated glass comprises a first glass plate, an infrared reflecting layer, a middle composite layer, a second glass plate and a low-radiation layer. The heat resistance coefficient ZR of the laminated glass meets the formula: ZR = (TIR / RIR) * e * 100, and ZR = 0.01-1.7. According to the laminated glass, by controlling and adjusting the TIR / RIR and the radiance e, the heat resistance coefficient ZR of the laminated glass can reach a preset low value level, so that the laminated glass has a relatively ideal heat blocking effect, and a relatively good human body surface feeling can be brought to passengers. Moreover, research finds that when ZR is more than or equal to 0.01 and less than or equal to 1.7, the laminated glass can achieve a relatively ideal heat blocking effect, and other functions of the laminated glass cannot be obviously reduced. Besides, the visible light transmittance TL1 of the first glass plate is larger than or equal to 88%, and the visible light transmittance TL2 of the second glass plate is larger than or equal to 80%, namely TL1 and TL2 are both large, so that the absorbed heat is reduced during sunlight irradiation in summer, and the scald defect caused by too large absorbed heat can be avoided.
