Description

technical field

[0001] The invention relates to the technical field of underground engineering technology, in particular to a drilling depth and verticality measuring device and a use method. Background technique

[0002] The subway station is composed of two parts, the enclosure structure and the main structure. During on-site construction, the enclosure structure should be constructed first, followed by the main structure, and finally the auxiliary structures (entrances, wind pavilions). The general form of the enclosure structure of the subway project is: Enclosure pile or ground connection wall structure; when the subway enclosure structure is constructed with cast-in-place piles or prefabricated piles, it is necessary to carry out the drilling operation of rotary drilling rig and long auger drilling rig first, and then carry out the lifting of reinforcement cage or prefabricated pile structure, and finally The pile-forming process of pouring concrete or cement soil; amo...

Embodiment 2

[0047] This embodiment discloses a method for using a drilling depth and verticality measuring device, comprising the following steps:

[0048] Step 1: According to the set position, use the total station to measure and position the point, determine the fixed point on the basis of the surrounding of the drill hole, and fix the positioning nail at the fixed point.

[0049] Step 2: According to the fixed point determined in step 1, insert the positioning nail into the positioning hole of the foot, fix the fixing plate on the foundation around the drilling hole through the foot, and set the fixing plate and the drilling hole coaxially.

[0050] Step 3: Turn the screw, the screw moves along its own axis, drives the support plate for leveling, observe the position of the bubble in the bubble level at any time, and turn the corresponding screw until the bubble in the bubble level is in the middle position, and the support plate is adjusted to the level state.

[0051] Step 4: Start...
