This invention discloses an intelligent generation method and system for foundation pit construction schemes based on working condition constraint deduction. Through foundation pit engineering data acquisition and analysis, construction of a foundation pit engineering semantic object model, construction of an engineering constraint graph, retrieval and adaptation verification of foundation construction scheme templates, deduction of construction working condition chains, parameter collaborative optimization and generation of candidate foundation pit construction schemes, generation of complete sets of construction schemes, consistency verification, and final scheme output, the invention achieves intelligent and rapid generation of foundation pit construction schemes, improves the accuracy of scheme adaptation to actual foundation pit working conditions, reduces labor costs, and ensures foundation pit construction safety and engineering quality. It solves the problems of low efficiency, insufficient personalization, low matching degree with actual working conditions, and excessive reliance on human experience in existing foundation pit construction scheme generation technologies.

The invention discloses a construction method of a connecting wall between adjacent basements in a top-down area, floor slabs of a first basement and a second basement are staggered on the two sides of a row of existing steel columns, and the construction method of the connecting wall comprises the steps that a foundation pit is excavated till the designed elevation of a first floor slab of the first basement is reached; a first wall inner beam is constructed at the design position, corresponding to the first floor slab design elevation, of the connecting wall; constructing the first floor slab, and connecting the first floor slab with the first wall inner beam to form a closed structure; the foundation pit continues to be excavated till the designed elevation of a second floor of the second basement is reached; a second wall inner beam is constructed at the design position, corresponding to the second floor slab design elevation, of the connecting wall; constructing the second floor slab, and connecting the second floor slab with the second wall inner beam to form a closed structure; the foundation pit continues to be excavated till the elevation where the foundation raft is located is reached, and the foundation raft is constructed; and a formwork is erected to pour the connecting wall, the first wall inner beam and the second wall inner beam are poured in the connecting wall, and the construction efficiency is improved through the construction method.

This invention relates to a putty adhesive for interior building decoration and its preparation method. The putty adhesive for interior building decoration comprises the following raw materials: soy protein isolate, polyvinyl alcohol, urea, silica sol, coupling agent, and water. This invention also provides a method for preparing the putty adhesive for interior building decoration according to this invention, comprising the following steps: adding soy protein isolate to water, adjusting the pH value with sodium hydroxide, then adding urea, heating to react, and obtaining a soy protein modified liquid; adding polyvinyl alcohol to water, heating, and cooling to obtain a polyvinyl alcohol aqueous solution; mixing the soy protein modified liquid and the polyvinyl alcohol aqueous solution, adding silica sol and a coupling agent, polymerizing, and cooling to obtain the putty adhesive for interior building decoration. This invention solves the problem that existing putty adhesives for interior building decoration contain formaldehyde, which pollutes the environment and affects human health.

The space utilization rate, the constructability and the environmental protection property of existing furniture can be improved at the same time. In particular, a cooling system based on Peltier elements may be mounted within the top plate to maintain comfort of the user's workspace and to cool the desktop surface without separate cooling equipment. By installing the Peltier element and the coolant chamber in the top plate, the temperature of the surface of the top plate can be reduced. In this way, the table top can be kept dry, extra cooling is not needed, and a user can work in a more comfortable working environment. By integrating the cooling device into the top plate member and the head member, the efficiency of the power supply device can be improved, and the cooling function can be integrally provided without installing additional equipment. This improves the ease of installation and maintenance. By using the skin-core-skin carbon fiber composite material, the weight and the strength of the office table can be realized at the same time, and the office table has excellent heat conductivity and excellent cooling and heat diffusion effects.

The release agent provided by the application has the advantages of high release performance, high release rate, small release agent dosage, small adhesion of a mold frame, small oil mist generation, high stability, good high-temperature resistance and the like when used in a micro-spraying process.

The invention discloses a modified epoxy curing agent based on KH-560 distillation residues as well as a preparation method and application of the modified epoxy curing agent. The preparation method comprises the following steps: A, putting a polyamine compound into a stirring kettle, and stirring; b, putting an accelerant into a stirring kettle, stirring the accelerant and the polyamine compound to obtain a mixed solution, uniformly mixing, introducing nitrogen into the stirring kettle, and replacing air in the kettle; c, the KH-560 distillation residues are put into a storage tank, nitrogen is introduced into the storage tank, and air in the storage tank is replaced; d, heating the mixed solution in the stirring kettle to a reaction temperature, and metering and dropwise adding the KH-560 distillation residue into the stirring kettle according to a theoretical equivalent to react; e, after dropwise adding is completed, liquid in the stirring kettle is subjected to heat preservation and continuous stirring at the reaction temperature, and the modified epoxy curing agent is obtained after discharging. According to the scheme, the KH-560 distillation residue can be safely and efficiently converted into the modified epoxy curing agent, the epoxy value in the KH-560 distillation residue is recycled, and meanwhile, the environment-friendly treatment cost is reduced.
