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 relates to the technical field of building construction, in particular to an anti-seepage construction method for a high-standard farmland transformation ditch, which comprises the following steps: S1, surveying and setting out; s2, cleaning the surface of the construction area; s3, a ditch is excavated; s4, laying a base layer cement blanket; s5, laying a cover layer cement blanket; s6, watering and curing; and S7, checking and accepting. According to the invention, the ground nails covering the surface of the base layer cement blanket of the cover layer cement blanket are arranged, so that structural weak points formed at the parts punctured by the ground nails are avoided, and the generation probability of hidden leakage channels is obviously reduced. Meanwhile, the paving mode of the double-layer cement blanket is arranged, the overall structural strength of the ditch can be improved, and the service life of the ditch is further prolonged.

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.

The utility model belongs to the field of building construction, and particularly relates to a simple assembly type shield leaking stoppage support unit and a support. The support unit comprises a support and a plate component. The support comprises two vertical supporting pieces, a connecting supporting piece arranged between the two vertical supporting pieces and transverse supporting pieces perpendicularly connected with the two ends of the connecting supporting piece. And the plate component is arranged above the transverse support frame. The simple assembly type shield leaking stoppage support solves various problems of traditional leaking stoppage construction, such as unreasonable placement, overlarge occupied space and the like, and meanwhile meets modern building construction requirements of rapidness, safety, environmental protection and the like.

The anti-falling building scaffold for building construction comprises a trolley and a supporting seat, the supporting seat is installed at the center position of the top end of the trolley, a telescopic arm is movably installed at the top end of the supporting seat and extends into the supporting seat, an adjusting arm is installed in the telescopic arm in a sliding mode, and the adjusting arm extends into the supporting seat. A connecting base is arranged at the end, away from the telescopic arm, of the adjusting arm, and a left standing table is installed on the outer wall of the end, away from the adjusting arm, of the connecting base. According to the utility model, the convenient safety protection, the rotary height adjustment and the extension operation of the building scaffold are realized, the building scaffold can conveniently enter the building scaffold from multiple directions, the operation range during high-altitude construction is increased, and the use convenience of the scaffold is improved.

The utility model discloses a dustproof construction coaming which comprises a dustproof construction coaming body, the dustproof construction coaming body comprises fixed stand columns, fixed bases are integrally formed at the bottom ends of the fixed stand columns, and a main coaming is arranged at the joint of the two fixed stand columns. By designing a spraying dust-falling mechanism, when the dustproof construction coaming body is used after being fixedly installed, a spraying head rotates in a water inlet through a threaded structure, a plugging head plugs one side of a water inlet through hole, and the water inlet is connected with a water pipe connected with an external high-pressure pump; water enters the water inlet through hole and the water inlet channel in a pressurized mode through the water inlet, water is sprayed to the outside through the spraying head after entering the water inlet channel, spraying dust falling treatment is conducted again while dust prevention is facilitated, dust falling treatment installation is convenient, and the installation cost is reduced; and therefore, the convenience of dust falling when the dustproof construction coaming main body is mounted at a construction position for dustproof enclosure is improved.

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.
