Large bridge pile foundation construction method with high pile bearing capacity

Abstract

The invention discloses a large bridge pile foundation construction method with high pile bearing capacity and relates to the field of bridge pile foundation installation. The large bridge pile foundation construction method specifically comprises the following steps: S1, firstly conveying pile foundations needing to be used to a pile foundation bearing capacity detection area for detection, measuring whether the bearing capacity of the pile foundations meets construction requirements or not, measuring whether the bearing capacity of the pile foundations meets standards or not, and simultaneously detecting the bearing capacity limit of the pile foundations. According to the large bridge pile foundation construction method with high pile bearing capacity, pile foundation measuring time in the step S1also needs to reach the standard, bridge pile foundation bearing capacity can be accurately measured, and the most accurate numerical value is obtained so that the problem can be avoided that the pile bearing capacity does not correspond to the pile foundations, great convenience can be brought to people, the rework rate is greatly reduced, the use of people is facilitated, and the problem is solved that an existing large-scale bridge pile foundation construction method with high pile bearing capacity cannot completely correspond to the measurement of the bridge pile bearing capacityand the subsequent foundation construction.

Description

technical field [0001] The invention relates to the field of bridge pile foundation installation, in particular to a large-scale bridge pile foundation construction method with high pile bearing capacity. Background technique [0002] A deep foundation composed of piles and a pile cap connected to the top of the pile or a single pile foundation connected by a column and a pile foundation, referred to as a pile foundation, if the pile body is completely buried in the soil, and the bottom surface of the cap is in contact with the soil, it is called Low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. The building pile foundation is usually a low cap pile foundation, and the bridge foundation is the most direct contact between the bridge structure and the foundation. The lower part is an important part of the lower structure of the bridge. The part of the grou...
