Assembled type movable blast wall

Abstract

An assembled type movable blast wall is formed by a plurality of blast wall units in an assembled mode. Each blast wall unit comprises a base, front pull rods, rear compression bars, a supporting frame, energy absorption layers and connecting bolts. Each supporting frame is fixed on the upper surface of the corresponding base, and one or more energy absorption layers are arranged inside each supporting frame in a filling mode. The energy absorption layers are formed by a plurality of prefabricated bodies which are made of EPS flow state concrete in an arrayed mode. A plurality of slide-resistant piles are distributed on the lower surface of each base. When multiple energy absorption layers are arranged, a middle layer is arranged between every two adjacent energy absorption layers. The assembled type movable blast wall can be deformed easily when undergoing impulse loads of the outside, the deformation is large, however, the flow stress level is quite low, in the compression deformation process, a large amount of power is consumed, the power is converted into energy dissipated in all sorts of modes like deformation, collapsing, fracturing and cell wall friction of holes in the structure, and thus the outside impact energy can be effectively absorbed. The assembled type movable blast wall further has the advantages of being rapid in assembling, low in cost and strong in stability.

Description

technical field [0001] The invention relates to the field of explosion-proof technology, in particular to an assembled mobile explosion-proof wall. Background technique [0002] Civil defense engineering is an important facility to prevent sudden enemy attacks, effectively cover personnel and materials, and preserve vital forces for combat counterattacks. It plays an important role in winning modern warfare. The mouth of the civil air defense project is the focus of the enemy's attack, and it is also an important part of our defense. With the development of science and technology, precision-guided weapons are used more and more in air strikes, with higher accuracy and higher explosive power. The stronger it is, the greater the intensity of air strikes. The existing protective measures for the mouth of civil air defense projects are mainly the setting of protective doors, but this has failed to meet the protection requirements of important protective structures under high-te...

AI Technical Summary

Problems solved by technology

The battlefield environment changes rapidly, and an effective defense system needs to be established in a short period of time. In addition, it is difficult for large-scale machinery to assist in the battlefield environment. The existing types of explosion-proof walls have the following problems: 1. High cost; 2. Insufficient resistance or poor energy absorption ; 3. The total weight is large; 4. The stability is poor; 5. The construction time is long, and it needs to be installed by machinery
