Embodiment

[0038] see figure 1 , this embodiment provides a closed construction method, the closed construction method provided by this embodiment can shorten the construction time, reduce the influence of weather, and improve the safety of construction.

[0039] Specific steps are as follows:

[0040] Step S100, excavating a foundation pit.

[0041] see figure 2 , wherein step S100 may include step S110 and step S120.

[0042] Step S110, survey the ground to be excavated, and plan the excavation path of the foundation pit. Wherein, the foundation pit is formed after the ground to be dug is excavated.

[0043] In this embodiment, firstly, the ground to be excavated is surveyed, and whether there is an obstacle in the path from the ground surface to the bottom of the foundation pit is surveyed.

[0044] see image 3 , wherein, step S110 may include step S112 and step S114.

[0045] Step S112, using ground radar to detect position information of underground obstacles.

[0046] In ...

Abstract

The embodiment of the invention provides a sealed construction method, and relates to the field of constructional engineering. The sealed construction method comprises the steps of excavating a foundation pit; placing a prefabricated concrete cushion matched with the foundation pit into the foundation pit; and sealing the concrete cushion into the foundation pit. The concrete cushion can be prefabricated in advance according to the size of the foundation pit and is directly placed in the foundation pit so as to directly seal the bottom after the foundation pit is excavated, so that the bottomis directly sealed after the foundation pit is excavated, the construction time is shortened, the weather effect is reduced, and the construction safety is improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a closed construction method. Background technique [0002] At present, in the construction field of deep foundation pit base closure construction, after the excavation is completed, a crushed stone cushion is laid according to the design requirements, and then a cast-in-place concrete cushion is laid to complete the deep foundation pit foundation closure construction. The current construction method needs to wait until the excavation of the foundation pit is completed or most of the base has been exposed before the cushion construction; the construction time is long. Contents of the invention [0003] Objects of the present invention include, for example, providing an enclosed construction method, which can thereby shorten construction time, reduce weather influence, and improve construction safety. [0004] Embodiments of the present invention can be realized like thi...
