Embodiment

[0055] Embodiment: the detection process of the present embodiment comprises the following steps:

[0056] 1. Ultrasonic testing implementation steps

[0057] ① Prepare ultrasonic testing instruments and supplies: concrete ultrasonic testing instrument and transducer with sound wave display, sufficient couplant, etc.;

[0058] ②According to the technical plan, set up bagged earth dam cofferdam or pile foundation cofferdam at the end of the wharf structure. figure 1 As shown, the cofferdam 2 connects the wharf end 1 and the revetment line 5 from the direction of the water area in front of the wharf, and then excavates the earthwork at the wharf end 1 inside the cofferdam 2 to form a foundation pit side wall 3 and a foundation pit support side wall 4. Detection of foundation pit.

[0059] Excavation is carried out at the rear side of the wharf wall structure at the most unfavorable geological position to form a detection foundation pit. The excavation site is as follows: fig...

Abstract

The invention discloses an in-situ detection method for safety of a gravity-type wharf. The in-situ detection method comprises the steps of detection investigation, detection of scouring changing conditions of foundation bed and base, detection of horizontal displacement, settling and inclination of the wharf, detection of wharf structure pattern, detection of wharf foundation bearing capacity, detection of wharf foundation bed thickness and detection of wharf wall behind backfilling material and physical mechanic indexes thereof, as well as checking computation of stability against sliding, checking computation of stability against inclination, checking computation of foundation bed bearing capacity and checking computation of foundation bearing capacity based on the detection data. The method can conduct in-situ detection on the displacement, the deformation, the foundation and the main structure of the wharf under the premise that the integrity and the operability of the main structure of the built wharf are ensured, and accurately judges the safety of the wharf according to detection result.

Description

technical field [0001] The invention relates to a detection method of a port hydraulic structure in a water conservancy project, in particular to an in-situ detection and evaluation method for the safety of a gravity-type cast-in-place concrete wharf or a masonry wharf. Background technique [0002] The State Council's "Opinions on Accelerating the Development of Inland Water Transport such as the Yangtze River" (Guo Fa [2011] No. 2) indicates that accelerating the development of inland water transport has become a national strategy, and inland water transport has become one of the strategic priorities of the comprehensive transportation system. "Several Opinions of the Ministry of Transport on Strengthening the Quality and Safety Management of Highway and Waterway Projects" (November 18, 2014) requires the implementation of a one-vote veto system for project quality and safety. Due to historical and other reasons, there are many old and backward port facilities in inland ri...
