Microporous cast-in-place piles for photovoltaic support

Applicability evaluation of cast-in-place bored pile in permafrost

In order to accelerate the refreezing process of cast-in-place pile and improve its freezing force in permafrost, a fast- freezing system (FFS) using the method of artificial

OPEN Vertical compressive bearing performance and optimization cast

place piles, eight manually‑excavated rock‑socketed cast‑in‑place piles were subjected to vertical compressive on‑site load and pile stress tests. The test results showed that the load

The utility model effectively solves the problem of large excavation amount of field cap by setting inclined cap on slope surface; by setting a number of microporous cast-in-place piles between

Field test research on post-grouting effect for super-long cast-in

The field static load test method was adopted for two test piles in a project in Zhejiang area of China, analyze the effect of post-grouting technique on super-long cast-in

Accurate detection technology of super long bored cast-in-place pile

The measuring instrument system is mainly composed of five parts: borehole probe ①, integrated control box ②, signal display ③, transmission cable ④ and depth code

Field study on post-grouting effects of cast-in-place bored piles

The post-pressure grouting technique has proven to be an effective method to enhance axial resistance. In this paper, field tests were conducted to investigate the performances of large

Frontiers | Reliability analysis of the cast-in-place

3 Numerical method. The commercial software ABAQUS is used to simulate the bearing capacity of the in situ cast-in-place bored pile nos. KYZ-1, KYZ-2, and KYZ-3 with their lengths L p of 52.5 m, 52.4 m, and 52.3

Thermal characteristics of cast-in-place pile foundations in warm

Pile foundations are widely used all over the world. The thermal characteristics of some pile foundations have been of concern, including those of energy piles (Rotta Loria and

Applicability evaluation of cast-in-place bored pile in permafrost

In order to verify the applicability of the three models for the thermal calculation of bored piles in permafrost regions, a cast-in-place pile investigation was conducted beside

The difference between cast-in-place piles and precast piles

Piles can be divided into precast piles (prestressed pipe piles) and cast-in-place piles (bored cast-in-place piles) according to different construction methods. Both are widely used in soft soil

Accurate detection technology of super long bored cast-in-place pile

Therefore, in view of the technical problem that it is difficult to accurately measure the concrete elevation and laitance thickness during the pouring of super long bored cast-in

Effect of freeze–thaw cycles on the performance of cast‐in‐place piles

However, because of the dynamic and cyclic variation in frozen ground affected by the atmosphere, the load transfer mechanism is not yet clear, and the current design is

Stability analysis of deep foundation pit with a double-row cast-in

The pit bottom support is a reinforced concrete structure that is monolithically cast with two lower 0.9 m diameter borehole cast-in-place piles to form the final load-bearing unit.

Horizontal and Uplift Bearing Characteristics of a Cast

Micropile groups have been progressively more frequently adopted in the construction of transmission tower bases due to their compact size and flexible construction advantages. However, the load-bearing

Common quality problems in bored cast-in-situ pile construction

Combined with practical engineering,the author analyzes the causes of quality problems in bored cast-in-situ pile construction as water oozing from pile casting,collapse of hole wall,deflection

Application and comparative analysis of Intelligent Monitoring

The whole construction process of four cast-in-place piles in two pile areas was monitored by the intelligent monitoring system, and the changes in the plane positions of pile
