Problems solved by technology

Among them, the drilling method is to measure the depth of the riprap by drilling holes at selected measuring points. The cost of a single drilling hole in the drilling method is too high. Generally, only a few points are selected to drill holes, resulting in too large errors in calculation results and low efficiency.
The volume balance method is based on the conversion of the volume transported by the riprap transport vehicle to obtain the corresponding amount of riprap. This method has a large cumulative error and will cause conflicts due to different statistical results from all parties.

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0028] Such as figure 1 as shown, figure 1 It is a schematic technical flow diagram of a method for estimating the amount of engineering rock dumping provided by the present invention. This embodiment is a roadbed project, which requires detection of the depth and amount of riprap within the design width of the road surface (side slopes are not included). Such as figure 2 as shown, figure 2 It is a schematic diagram of the layout of the cross-section survey line in this embodiment. This test is arranged along the entire length of the cross-section. The distance between the sections is set to 20m, and the distance between the measurement points of the geological radar detection on a section...

Abstract

The invention discloses an estimation method for engineering riprap amount. The estimation method for the engineering riprap amount is based on the geological radar detection technology and the CAD software operation technology and mainly comprises the operation steps of determining a dielectric constant; carrying out geological radar detection; interpreting a geological radar result map; carrying out CAD processing on the geological radar result map; checking the sectional area of riprap; and calculating the volume of the riprap. According to the invention, the riprap amount can be accurately estimated without damage and with low cost and high efficiency, and the whole calculation process is simple and easy to understand. The estimation method can be widely used for detection work of practical engineering such as roadbeds, cofferdams and bulwarks.

Description

technical field [0001] The invention relates to a method for estimating the amount of riprap in engineering, and belongs to the technical field of riprap management in engineering. Background technique [0002] At present, as a construction method for soft foundation treatment, blasting and squeezing are widely used in cofferdams, breakwaters and other projects. This method has the advantages of short construction period, relatively dense riprap, and good overall stability. A large amount of riprap is consumed in such projects, and the calculation of the specific amount of riprap has always been a difficult problem in the completion settlement. The traditional calculation methods include drilling method and volume balance method. Wherein the drilling method is to measure the riprap depth by drilling holes at selected measuring points. The single drilling cost of the drilling method is too high, and generally only a few points are selected to drill holes, resulting in too lar...
