“…For further preparation for full-scale studies of the selected structural solutions for strengthening vertical walls of trenches and excavations, it is necessary to carry out preliminary model-experimental computer and full-scale studies for conditions of the formed urban development by analogy with the methods applied in the articles [33][34][35]).…”

The most commonly used designs for securing vertical walls of trenches and excavations in the actual conditions of work in them do not allow for strict compliance with regulatory safety requirements. To prevent ground failure in trenches and excavations, you can develop ground with a slope angle smaller than the natural slope angle. Development of excavations with vertical walls without securing them is limited to their depth depending on the strength properties of the ground. When excavating to a depth of up to 2-3 m the vertical walls of trenches and excavations must be secured. In this case, the development and backfilling of such excavations should be carried out using constructive solutions (e.g. anchoring), which in original combinations with modern construction materials and technologies allow various construction works to be safely performed in them.

“…All of the above loads are not as significant as the loads exposed during concreting since it is when laying a concrete mixture that the greatest loads on the formwork occur. The most critical loads are horizontal loads caused by the lateral pressure of a concrete mixture, for which the formwork of vertical structures is calculated [18][19][20].…”

This work aims to develop effective technology for erecting monolithic enclosing structures of buildings made of expanded polystyrene concrete. As a result of the research carried out, a model of large-panel formwork made of ABS plastic for concreting monolithic walls with an expanded polystyrene concrete mixture was developed, representing rectangular panels of a size of 3000 x 1200 x 40 mm. To ensure the necessary strength and rigidity, the outer side of the formwork is made cellular with a large number of longitudinal and transverse stiffeners placed in increments of 300 mm. We have developed a technology for erecting monolithic enclosing structures of buildings made of expanded polystyrene concrete using a mobile concrete-mixing unit. The following are technical and economic indicators for manufacturing monolithic walls out of expanded polystyrene concrete of a volume of 46 m3 : the cost is 354.784 thousand rubles, and the labor intensity and unit capacity are 163.76 people.*h and 27.36 units.*h, respectively. The results significantly offer the construction industry a solution to reduce the labor intensity of construction and installation while manufacturing cost-effective monolithic enclosing structures for buildings.

“…In civil construction engineering, with the continuous improvement of its construction quality requirements, the requirements are not only limited to cost performance, but also put forward higher requirements for its beauty [1] . But in the past civil engineering, there are often defects such as uneven surface and unreasonable structure design, which affect the overall beauty of the building [2] . Based on this, the concrete structure construction technology should come into being, through this technology, it can play a certain auxiliary role for the improvement of engineering quality, and improve the building surface smoothness, which can meet the practical needs of the aesthetic degree in civil engineering [3][4] .…”

In civil engineering, the construction quality requirements of civil construction projects are getting higher and higher. There are still problems with uneven surface or unreasonable structural design in existing construction projects. Therefore, the article chooses concrete structure templates according to the construction type and characteristics The system uses direct and indirect methods for formwork installation and concrete pouring, so as to complete the application of concrete structure construction technology in civil engineering construction. The experiment proves that this method has higher construction accuracy and better construction effect.
