Embodiment Construction

[0015] Such as figure 1 , figure 2 As shown, a device for measuring the thickness of the sediment layer of a rotary drilling bored pile includes a steel ruler 1 and a steel triangular support disc. The steel triangular support disc is composed of three long steel bars 3 fixedly welded on the edge of the steel disc 2, and the center of the steel disc 2 is provided with a round hole 4 with a wire mouth, and the reinforcing bar screw 5 passes through the round hole 4 and Steel disc 2 connection.

[0016] The steel disc 2 is a thin steel disc with a thickness of 3 mm. The long steel bar 3 is a 200mm long steel bar of φ8. The diameter of the circular hole 4 with the wire mouth is 10mm. Described reinforcement screw rod 5 is the 200mm long steel bar of φ 10. Described steel ruler 1 adopts 50m steel ruler.

[0017] Steps:

[0018] Step 1: During the process of embedding the steel casing 6, use a level to measure so that the elevation of the upper edge of the steel casing 6 is...

Abstract

Provided is an apparatus for measuring the thickness of a sediment layer of a rotary excavating bored pile. The apparatus comprises a steel rule and a steel triangular support disc. The steel triangular support disc is formed by fixing three long steel bars to the edge of a steel disc. The center of the steel disc is provided with a circular hole with threads. A steel bar screw passes through the circular hole and is connected with the steel disc. The apparatus for measuring the thickness of the sediment layer of the rotary excavating bored pile is simple in structure, economic and practical, and accurate and convenient in measurement, and well solves a problem of large difficulty in measurement of the sediment layer of the bottom a pile.

Description

technical field [0001] The invention relates to a device for measuring the thickness of a sediment layer of a rotary drilling bored pile, which relates to the field of bored pile construction. Background technique [0002] Bored piles are widely used in various construction projects due to their advantages such as wide application range, high single pile bearing capacity, low construction noise, small vibration and low unit price. With the increasing number of high-rise buildings, the requirements for the bearing capacity of pile foundations are also getting higher and higher. However, due to the particularity of the construction technology of bored piles, their bearing capacity is greatly affected by factors in the construction, especially the sediment layer at the bottom of the hole seriously affects the quality of the pile foundation. Therefore, during the construction process, strengthening the detection and control of the thickness of the sediment at the bottom of the ...
