“…It is obvious that MPWSS is a crucial part of ensuring normal operations of mud pump and optimizing dredging operations. Its primary function is to maintain the necessary seal water pressure for the mud pump shaft seal, preventing the ingress of mud into the pump shaft seal [6]. Consequently, maintaining the proper seal water pressure at the shaft is imperative for the uninterrupted and regular operation of the mud pump.…”

The mud pump water sealing system (MPWSS) is important in the efficient operation and prolonged service life of the cutter suction dredger’s (CSD) mud pump. Considering that the underwater pump operates underwater and the shaft seal water pressure sensor is prone to failure, a hybrid deep learning model MCNN transformer is proposed to predict the underwater pump shaft seal water pressure in the event of sensor failure. This paper uses big data from the dredging project to deeply excavate the relationship between the shaft end sealing water pressure and other construction data by combining experience and artificial intelligence, and then uses multi-scale convolutional neural network (MCNN) to reconstruct the data, highlighting the time series characteristics of the multi-scale data were then input into the transformer model for prediction, and compared with a single MCNN, transformer model and four other neural networks. Finally, the cutter suction dredger “Hua An Long” was selected as an application research case; experimental comparisons were conducted on seven different models to verify the accuracy and applicability of the MCNN-transformer model.

The drainage and firefighting water systems are critical components of construction projects. Due to the complexity and multitude of piping systems, issues such as impractical space arrangements and pipeline collisions can arise during construction. BIM technology enhances the design quality and efficiency of these systems through parametric integration of building information and three-dimensional visualization modeling. Based on this research background, this paper firstly constructs the model of water supply and drainage and fire fighting water based on BIM technology, plays the scalability of Revit, carries out the secondary development of Revit, and completes the program development of water supply and drainage, and fire fighting water pipeline height detection and pipeline automatic avoidance function by combining with C# language. This paper takes a building in the Shangcheng District of Hangzhou City to conduct empirical research, and the results show that collision detection through BIM technology saves a lot of time, improves efficiency significantly, and has higher detection accuracy. In addition, this paper utilizes a comprehensive evaluation system to objectively evaluate the effects of drainage and firefighting water construction in construction projects based on BIM technology. This study uses BIM technology to realize further development and exploration in the process of building drainage and fire water construction, reduce the conflict points in the process of drainage and fire water design, and improve the detection efficiency and accuracy in the design process.
