The invention discloses a preparation method of an environment-friendly high-polymer compound self-repairing water-proof material. The method comprises the following steps that 1, absolute ethyl alcohol and ethyl acetate are stirred evenly at a room temperature, and an obtained mixture is used as a solvent; 2, epoxy resin is added into the solvent obtained in the step 1, and at the room temperature, powerful stirring is conducted to obtain a solution; 3, superabsorbent fibers are added into the solution, and at the room temperature, powerful stirring and dispersion are conducted for 2-4 hoursto obtain suspension; 4, the suspension is subjected to even blade coating on a first rubber piece, natural standing and curing are conducted to obtain the rubber piece covered by a suspension layer,and the suspension layer is covered by a second rubber piece to obtain a compound sheet of a three-layer structure; 5, two surfaces of the compound sheet are covered by methyl silicone oil for vulcanization treatment, and after cooling is conducted, the high-polymer compound self-repairing water-proof material is obtained. According to the preparation method of the high-polymer compound self-repairing water-proof material, rubber and resin are combined, and have a synergistic effect on waterproofing, and the environment-friendly high-polymer compound self-repairing water-proof material has self-repairing property, and has the advantages of being environmentally friendly, anti-osmosis, ageing-resistant, long in life cycle and the like.

The invention relates to a suction liquid feeding electronic cigarette. The suction liquid feeding electronic cigarette comprises a shell, an oil storage bin, a heating body, a cigarette holder, a one-way valve, a heating body wire and a battery. The suction liquid feeding electronic cigarette is characterized in that a separating plate is arranged to divide the electronic cigarette into a positive air pressure area and a negative air pressure area. Two holes including an air hole and an oil hole are formed in the separating plate; one end of the air hole is close to the cigarette holder, and the other end of the air hole is connected with the atmosphere through a shell; and the end, close to the cigarette holder, of the oil hole is connected with the other end, close to a heating body, of the oil hole through the one-way valve and the oil storage bin. When smoking is carried out, tobacco liquid is injected into the heating body due to air differential pressure to generate smoke. The suction liquid feeding electronic cigarette has the beneficial effects that the good heat efficiency is obtained; the good tobacco liquid feeding control is achieved; the good seepage prevention is achieved; and the good cost performance is achieved.

The invention relates to a passive self-control liquid flow meter, the limiting rotating shaft of the quantitative mechanism is fixed on the rotating shaft gear and connected with the quantitative spring, the rotating shaft gear is connected with the combined ratchet, and the combined ratchet is connected to drive the transition gear; the positioning control mechanism The positioning wheel is fixed on the limit shaft, the positioning wheel has a positioning groove, and the closing plate is provided with a positioning block, and the positioning block cooperates with the positioning groove to control the opening and closing of the closing plate; Valve cavity, the opening of the inner valve cavity is in the longitudinal direction, the closing plate is closed with the opening of the inner valve cavity, the closing plate is fixed in the watch body and can rotate, the return spring is arranged outside the cavity of the inner valve cavity, and the return spring is connected with the closing plate. Since there is an inner valve cavity in the meter body, the closing plate is arranged horizontally at the inner valve cavity opening inside the meter body, and the closing plate cannot be seen from the liquid inlet of the flow meter at all, which prevents the artificial flow from the side of the liquid inlet. To pry open the closing plate, and strengthen the sealing effect better, so it has a good effect of preventing water leakage.

The invention discloses a novel reinforced concrete drainage pipe and a manufacturing method thereof. For the existing problem in the reinforced concrete drainage pipeline, the invention provides the key technology for manufacturing a novel reinforced concrete pipe in the following three aspects that: a novel anti-corrosion measure and a port type are used against the environmental factors to improve durability of the pipeline and tightness of the port; with regard to the pipeline itself, formulation of reactive powder concrete (RPC) suited for a drainage pipe is employed as the raw material, so that the strength is higher, the stability is better and the structure is more compact to block the possibly formed permeation passage; and the pipe is cheaper and lighter. The method fundamentally improves the basic performance of the reinforced concrete drainage pipeline. Due to the reduced weight and tighter port, the standard length (2.5 m) of the drainage pipeline is lengthened to 4-6 m.

The invention relates to the technical field of agricultural product breeding devices, in particular to an artificial honeycomb and a preparation method thereof. The artificial honeycomb includes a frame, and a honeycomb cell composed of a plurality of regular hexagonal columnar honeycomb cells is arranged in the frame, and the honeycomb cell is integrally molded by epoxy resin. Through the above technical solution, the artificial honeycomb provided by the present disclosure can solve the problem of poor structural stability of the honeycomb in the prior art.

The invention belongs to the technical field of road slope strengthening, and relates to a road slope strengthening treatment method based on plant stem and root system grouting. The method comprises the following steps that firstly, gramineae plants with the developed root systems and the powerful growth capability are sown to a slope surface of a road slope; secondly, after the gramineae plants naturally wither, the branches at the upper portions of the gramineae plants are shorn away, and gramineae plant stems are reserved; thirdly, grouting liquid is prepared, the density of the grouting liquid ranges from 1.2 g / cm<3> to 2.0 g / cm<3>, and the grouting liquid is the mixture of epoxy resin and polyamide resin; fourthly, the grouting liquid is injected into the root systems of the gramineae plants through gramineae plant conduits of the gramineae plant stems; and fifthly, the unearthed position of the gramineae plant stems on the ground serves as the circle center, and the grouting liquid is injected in the circle with the radius ranging from 5 cm to 10 cm. The provided road slope strengthening treatment method based on plant stem and root system grouting is low in cost, green, environment-friendly, high in reliability, capable of facilitating curing, high in adhering force and good in mechanical performance.
