Description

Technical Field

[0001] The utility model belongs to the technical field of deep foundation pit safety protection equipment, and in particular relates to a bionic tortoise shell safety protection device for deep foundation pit construction. Background Art

[0002] The foundation pit is a pit excavated at the design location of the foundation according to the base elevation and the plane size of the foundation. In modern cities, new buildings (or structures) are generally located in densely packed buildings, and the construction site is very narrow. The foundations of some new projects are even right next to the foundations of existing buildings (or structures). In such a complex environment, the construction of deep foundation pit projects will inevitably affect the existing buildings, structures, roads and other engineering facilities within a certain range of the surrounding area, thereby causing deformation of the existing engineering facilities around the foundation pit and generating additional stress inside. According to relevant research statistics, the accident rate of urban foundation pit projects generally accounts for about 20% of the total number of projects, and in some areas it is even as high as 30%, and most of them are deep foundation pit engineering accidents. At present, the deep foundation pits of deep foundation pit projects in major cities in my country are getting closer and closer to the surrounding buildings, the deep foundation pit projects are getting deeper and deeper, the scale and size of the foundation pits are getting larger and larger, and the construction sites are getting more and more compact. Once a local collapse accident occurs in the deep foundation pit, due to the rapid collapse speed, the construction workers cannot escape from the scene in the first time, which causes a burial accident and leads to mechanical asphyxiation and death of the construction workers.

[0003] At present, the relevant laws and regulations on deep foundation pit construction plans and safety management have been relatively complete, and there are also relatively complete rescue measures for emergency rescue after accidents. However, there are no relevant measures on how to effectively protect construction workers from mechanical asphyxiation in the first time of an accident, so as to buy sufficient time for emergency rescue after an accident and ensure the safety of construction workers. Utility Model Content

[0004] The utility model aims to provide a bionic tortoise shell safety protection device for deep foundation pit construction, which reduces the mechanical suffocation damage caused to people when a foundation pit collapse accident occurs and facilitates the rescue of personnel.

[0005] The technical solution adopted by the utility model is a bionic tortoise shell safety protection device for deep foundation pit construction, comprising a tortoise shell type reinforced safety shell, the inner wall of the tortoise shell type reinforced safety shell is fixedly connected with a tortoise shell type reinforced safety inner shell, an emergency entrance gate is arranged on the tortoise shell type reinforced safety shell, a through hole is opened at the emergency entrance gate of the tortoise shell type reinforced safety inner shell, a first emergency device and a second emergency device are fixedly connected with the inner wall of the tortoise shell type reinforced safety inner shell, and a plurality of safety chair devices are also fixedly connected to the tortoise shell type reinforced safety inner shell.

[0006] The utility model is also characterized in that:

[0007] A plurality of lifting rings are arranged on the tortoise shell type reinforced containment shell, and a plurality of wheels are fixedly connected to the tortoise shell type reinforced containment shell.

[0008] The tortoise shell reinforced safety shell includes a hexagonal tortoise shell reinforced safety block, which is fixedly connected to six irregular tortoise shell reinforced safety blocks by a first reinforcing connecting rib, and the six irregular tortoise shell reinforced safety blocks are fixedly connected to each other by a second reinforcing connecting rib, and the end faces of the six irregular tortoise shell reinforced safety blocks are commonly fixedly connected to a chassis, and a number of wheels are fixedly connected to the chassis.

[0009] The first emergency equipment includes emergency survival dry food, drinking water, oxygen cylinders and emergency medical insurance.

[0010] The second emergency device includes an intercom, a signal transmitter, a GPS locator and an emergency lighting lamp. The safety chair device includes a safety chair, a shock absorbing spring is fixedly connected to the bottom of the safety chair, the other end of the shock absorbing spring is fixedly connected to the bottom surface of the tortoise shell reinforced safety inner shell, the backrest of the safety chair is fixedly connected to the side of the tortoise shell reinforced safety inner shell, and a safety belt is provided on the side of the safety chair.

[0011] The beneficial effects of the utility model are:

[0012] The bionic tortoise shell safety protection device for deep foundation pit construction provided by the utility model can place construction workers inside the safety device as soon as a collapse accident occurs, prevent the collapsed soil from pouring in, and thus reduce the risk of mechanical asphyxiation of personnel; by designing the shape distribution of the reinforcing ribs, the gravity and stress of the collapsed soil can be transmitted and dispersed, so as to achieve the purpose of improving the mechanical properties and safety performance of the safety protection device, and at the same time the whole device is relatively light and can be quickly moved and transported; the emergency supplies of emergency survival dry food, drinking water, oxygen cylinders, walkie-talkies, signal transmitters, GPS positioning devices, and emergency lighting can meet the oxygen, water, and food needs of construction workers for several days, and emergency medical insurance can be provided so that personnel with minor injuries can receive preliminary medical treatment, send distress signals to the outside world, and wait for emergency rescue personnel to rescue them.
