A glaucoma drain for non-penetrating deep sclerotorny is made of non-resorbable and hydrophilic synthetic material. The drain is configured to be entirely covered by the scleral flap and totally inserted in the intrascleral space. It comprises a transverse bar (110) at one front end of the drain and a longitudinal body (120) extending longitudinally from said transverse bar. The transverse bar (110, 10) is configured to run along and cover the Schlemm's canal (CS) and the opposite ends are configured to penetrate beneath the deep sclera inside the Sclernm's canal. A hole (125) between the arms of the bar provides a target for possible YAG laser micro-punctures.

PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of suppressing damage such as a channel bottom crack by effectively enhancing a stone non-biting property. ŽSOLUTION: At the channel bottom 9a of a circumferential groove 9 formed on the tread surface, a protrusion 10 is formed extending along the extending direction of the circumferential groove 9. The protrusion 10 comprises a head top 11 protruding toward the outer periphery of the tire and a base 12 having a width narrower than that of the head top 11 and connecting the head top 11 and the channel bottom 9a. When a small stone is bitten, the head top is tilted around the base 12 and the protrusion 10 is totally deflected and deformed, thereby generating a reaction force based on a deformation restoring force.

The invention relates to the technical field of sponge city construction, in particular to a sponge city water circulation system, and aims to overcome the defects that in the process of collecting and recycling city rainfall in the prior art, when the rainfall is large, a drainage system difficultly drains water normally, and city waterlogging is likely to be caused. Wherein the road surface layer is arranged on an urban surface road, the permeable pipeline is used for collecting rainwater permeated into the road surface layer, the rainwater overflow well is used for slowing down the rainwater discharge rate, and the drainage pipeline is used for collecting rainwater and conveying and discharging the rainwater; two symmetrically-arranged water passing holes are formed in the inner side wall of the rainwater overflow well; by means of the sponge city drainage system, the drainage capacity of the sponge city is enhanced, the possibility of urban inland inundation is reduced, and then the stability of the sponge city is improved.

The invention discloses a green environment-friendly comprehensive management method for high-steep loess landslide. The green environment-friendly comprehensive management method comprises the following steps: carrying out step-by-step cutting on the slope side of a high-steep loess landslide body; leveling the steps of each stage and backfilling reinforced soil on the steps of each stage; filling soil and covering after the reinforced soil is backfilled; pumping soil nails into the reinforced soil; driving a pile foundation into the bottom end of the backfilled reinforced soil at the front edge of the bottom of the high-steep loess landslide; then arranging an anti-slip retaining wall on the outer side of the backfilling reinforced soil; arranging vertical drainage pipes in a slope body;arranging horizontal drainage pipes at the top of the slope body, at the steps of each stage and at the bottom of the slope body; screening, fertilizing and shotcreting the slope side. The comprehensive prevention and control method disclosed by the invention has the advantages that the stress in the slope can be well dispersed and plastic failure is avoided; a perfect drainage system ensures thedrainage of the whole side slope and avoids the effect of rainfall infiltration on the stability of the side slope; in addition, the method disclosed by the invention is a green construction method,and has the advantages of economical raw materials, convenience in construction and suitability for wide application in high-steep landslide treatment in loess areas.

In drainage for coast and reservoir bank slopes by using a siphon drainage method, there exists a defect of difficult self-restoring of siphonic action because of reduction in vacuum degree in a siphon after the siphonic action pauses due to groundwater recession. The present invention provides a drainage device capable of activating siphonic action in real time. The device is composed of an open-type dam, an air chamber, a siphon, an exhaust pipe, an air replenishing pipe, and a one-way valve. The air chamber is disposed at the crest of the open-type dam; one end of the siphon extends below the phreatic line of a slope, and the other end of the siphon extends through the air chamber and below the seawater level; one end of the exhaust pipe extends below the phreatic line of the rear edge of the slope, and the other end of the exhaust pipe is connected to the air chamber; and the air replenishing pipe is disposed at the upper end of the air chamber. The device provides power for the siphonic action with guarantee for self-restoring of the siphonic action. Moreover, the device employs a pile foundation with low consumption of materials and low construction costs in the face of great depth of water before a slope, and thus is applicable to not only coast slopes but also reservoir bank slopes with extra-deep water levels.
