The invention provides a construction parameter optimization method and device for leakage prevention of drilling fluid while drilling. The method comprises the steps that monitoring data while drilling are obtained in real time, and the monitoring data while drilling at least comprise drilling fluid pool volume change data, vertical pipe pressure and leakage rate; based on the while-drilling monitoring data, identifying the current leakage layer and the corresponding leakage layer characteristics in real time; according to the identified leakage layer features, matching a matched plugging material from a pre-built plugging material knowledge base, the plugging material knowledge base comprising reservoir protection performance indexes of the material; and calculating an optimized construction parameter set based on the identified leakage layer features and the matched plugging material. According to the method, accurate and dynamic adaptation of the construction parameters and the current leakage layer state is achieved, so that the leakage stoppage success rate is effectively increased, and the completeness of the carbon dioxide reservoir is ensured.

The invention belongs to the technical field of concrete prefabricated parts, and particularly relates to a leakage-proof device with a joint bar formwork, an auxiliary device and a leakage-proof construction method. The leakage-proof device comprises an insertion piece template, a plurality of long grooves are formed in the insertion piece template side by side, and the distance between every two adjacent long grooves is kept consistent with the distance between the bridge deck slab joint bars; a plurality of joint bar grooves are formed in the side wall of the long groove, the shape and the size of the joint bar grooves are consistent with those of the cross sections of joint bars of the bridge deck slab, after the insert template is installed in place, the positions of the joint bar grooves correspond to those of the joint bars, and one joint bar is arranged in each joint bar groove in a penetrating mode; a blocking protrusion is formed between every two adjacent joint bar grooves and used for blocking gaps between every two adjacent joint bars. And the top plate is arranged above the insert template, and the top plate is perpendicular to the insert template. According to the leakage-proof device, the production efficiency of the prefabricated bridge deck can be greatly improved, and the production cycle of the prefabricated bridge deck can be shortened.

This utility model provides a crack-resistant and seepage-proof water feature pool construction device, belonging to the field of construction equipment technology. The utility model includes a pole body, which serves as a support for installing construction components; a roller brush, which is detachably mounted on the pole body via an assembly assembly, wherein the roller brush rolls against the inner wall of the water feature pool to apply waterproof coating to its inner wall; and a collection assembly, which is detachably mounted on the pole body, wherein the collection assembly is positioned on the side of the roller brush near the handle of the pole body to intercept falling coating. The collection assembly includes a rectangular tube, which is fixed to the pole body. This utility model, by setting up a collection assembly, can intercept waterproof coating falling from the roller brush, reducing the risk of coating dripping from the roller brush into the eyes of personnel during construction on the side walls of the water feature pool, thus improving construction safety and ground cleanliness.

The invention provides a moisture-proof and water-proof treatment process for a whole house. The treatment process comprises the following steps of base layer treatment, pipeline grooving, hole crack treatment, base layer pretreatment before damp-proof construction, damp-proof slurry brushing, waterproof roll laying at the wall root internal corner, damp-proof film laying on the ground, putty layer coating and scraping, primer and finish paint brushing, internal corner sealing and skirting line installation. By forming multiple waterproof protections, the damp-proof and waterproof effects can be greatly improved, the phenomena of alkalization, peeling, putty layer pulverization and falling off and bulging at the wall root are avoided, then subsequent repair and maintenance are avoided, the economic property loss is reduced, and meanwhile it is avoided that mildew spots are gradually generated after alkalization, and harm is caused to the body health of a user.
