Problems solved by technology

[0002] In order to control the layer thickness of the backfill soil and prevent the layer thickness from being too large, the previous construction method relied on existing buildings (such as foundations, walls, and municipal pipe wells) to mark the backfill control line and backfill layer by layer, but this method is limited to site conditions, and It is effective for layer thickness control within a certain range around the building. Another way is to rely on the level to measure the point elevation control at a certain interval, but this method is time-consuming and laborious, and the measurement process will affect the backfilling construction work and affect the construction progress.

Embodiment Construction

[0021] Such as Figure 1-4 Shown: an instrument for controlling the thickness of backfill soil, which includes a scale rod 1 with a screw end, a fixing device, and a crosshair laser transmitter 5; The horizontal cylinder 3 and the vertical cylinder 4 at the end, the horizontal cylinder is provided with an alignment line 31 and a bolt hole 32 corresponding to the crosshair laser transmitter, and the crosshair laser transmitter is fixed in the horizontal cylinder; The vertical cylinder body is provided with a scale hole 41, and a scale rod with a helical end is fixed in the vertical cylinder body.

[0022] A method for using a backfill thickness control instrument, comprising the steps of:

[0023] Step 1: Drill the scale rod vertically into the soil layer until the zero scale line is flush with the surface of the soil layer;

[0024] Step 2: Fix the crosshair laser transmitter to the fixing device. There are alignment lines on the surface of the fixing device and the crosshai...

Abstract

The invention relates to a backfill soil thickness control instrument which comprises a scale rod with a spiral end, a fixing device and a cross laser transmitter. The fixing device comprises a levelbubble instrument which is horizontally arranged, and a transverse cylinder and a vertical cylinder which are arranged at two ends of the level bubble instrument, the transverse cylinder is provided with an alignment line corresponding to the cross laser emitter, and the cross laser emitter is fixed in the transverse cylinder; scale holes are formed in the vertical cylinder body, and the scale rodwith the spiral end is fixed in the vertical cylinder body. The relative elevation of backfill soil can be controlled within the laser radiation range; the effect is visual and obvious, manpower, material resources and time are saved, the quality is guaranteed, and the progress is not influenced.

Description

technical field [0001] The invention relates to an instrument for controlling the thickness of backfill soil and a method for using the same. Background technique [0002] In order to control the layer thickness of the backfill soil and prevent the layer thickness from being too large, the previous construction method relied on existing buildings (such as foundations, walls, and municipal pipe wells) to mark the backfill control line and backfill layer by layer, but this method is limited to site conditions, and It is effective for layer thickness control within a certain range around the building. Another way is to rely on the level to measure the point elevation control at a certain interval, but this method is time-consuming and laborious, and the measurement process will affect the backfilling construction work and affect the construction progress. Contents of the invention [0003] The invention aims at overcoming the defects of the prior art, and provides a backfill ...
