Problems solved by technology

[0003] However, after the construction personnel dug the trench, they generally do not support the trench, so that the trench may collapse; after the trench collapses, the operator needs to rework, which will increase the labor intensity of the operator; Furthermore, the construction personnel may be injured when the trench collapses, thereby threatening the life safety of the operators

Embodiment

[0035]Embodiment: a kind of foundation construction ditch digs first and then props up method, comprises the following steps: a. Digging a ditch 2: digging a ditch 2 on the soil layer 1 according to the drawing; Carry out the installation of multiple sets of supporting devices 3 in 2, and support the two side walls of the trench 2 through multiple sets of supporting devices 3; c. install drainage devices; install drainage devices in the soil layer 1 next to the trench 2, and pass The drainage device drains the water in the soil layer 1. The both sides of ditch 2 are supported by support device 3, thereby can reduce the possibility that ditch 2 collapses; By arranging drainage device, the water in ditch 2 peripheral soil layer 1 can be discharged, thereby can further The possibility of collapse of the sidewall of the trench 2 is reduced.

[0036] Such as figure 1 with figure 2 As shown, in step b, each group of supporting devices 3 includes a base plate 31 placed at the bot...

Abstract

The invention discloses a method for earlier excavation and later supporting of a groove in foundation construction and relates to the technical field of building construction. The technical solutionis characterized by comprising the steps of (a) excavation of the groove, (b) installation of supporting devices and (c) installation of a drainage device, wherein at the step (a), the groove is excavated on a soil layer according to a drawing; at the step (b), the multiple supporting devices are installed in the groove, and two side walls of the groove are supported by the multiple groups of supporting devices; and at the step (c), the drainage device is installed in the soil layer beside the groove, and water in the soil layer is discharged by the drainage device. The method disclosed by theinvention can reduce possibility in groove collapse through setting of the supporting devices.

Description

technical field [0001] The invention relates to the technical field of building construction, more specifically, it relates to a method for excavating a foundation construction trench first and then supporting it. Background technique [0002] In engineering, if the bottom width is less than 3m and the bottom length is more than 3 times the width, it will be calculated as a groove. In order to make the foundation more stable, some deep trenches are often dug in the soil layer, then the steel cage is laid, and then the concrete is poured. [0003] However, after the construction personnel dug the trench, they generally do not support the trench, so that the trench may collapse; after the trench collapses, the operator needs to rework, which will increase the labor intensity of the operator; Furthermore, the construction personnel may be injured when the trench collapses, thereby threatening the life safety of the operating personnel. Contents of the invention [0004] Aim...
