Problems solved by technology

[0003] At present, in the construction of housing construction, road engineering, municipal engineering and water conservancy projects, dynamic penetrating sounding devices must be used to carry out dynamic penetrating sounding experiments. The number of impacts of dynamic penetrating testing is large, and it is troublesome for the implementers to count the number of hammering impacts of dynamic penetrating testing, and it is easy to make mistakes

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] A construction recorder for gravity penetration testing, comprising a power probe rod 1, a conical probe 2, an elevation control part 3 and a counting assembly 4, the elevation control part 3 and the counting assembly 4 are respectively connected to the power probe rod 1, and the conical probe 2 is installed on The end of the power probe rod 1 senses the drilling depth of the power probe rod 1 through the setting of the elevation control part 3, and records the hammering times through the counting component 4, without manual recording, which improves data accuracy and facilitates Post-construction analysis.

[0022] The counting assembly 4 includes a counting head 5, a contact 6 and a data line 7. The counting head 5 is slidably installed in the power probe 1, the contact 6 is adapted to the counting head 5, the data line 7 is connected to the contact 6, and ham...

Abstract

A construction recorder for gravity sounding comprises a power probe rod, a conical probe, an elevation control piece and a counting assembly. The elevation control piece and the counting assembly are connected with the power probe rod, the conical probe is installed at the end of the power probe rod, and the drilling depth of the power probe rod is sensed through the arrangement of the elevation control piece; the number of hammering times is recorded through the counting assembly, manual recording is not needed, the data accuracy is improved, and later construction analysis is facilitated.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a construction recorder for gravity penetration testing. Background technique [0002] Dynamic testing, also known as cone dynamic penetration testing DPT, is to use a certain mass of weight to drive a standard-sized probe connected to a dynamic penetration test and a probe rod into the soil. The number of hammering required to judge the mechanical properties of the soil has dual performances of investigation and testing. [0003] At present, in the construction of housing construction, road engineering, municipal engineering and water conservancy projects, dynamic penetrating sounding devices must be used to carry out dynamic penetrating sounding experiments. There are many blows of dynamic penetrating testing, and it is troublesome and error-prone for implementers to count the number of hammering blows of dynamic penetrating testing. Contents of the inventio...
