中文拼音 [gùzhuāngkuāi]
固樁塊
英文
wedge-
The characteristics of high pressure gyratory sprayed pumping discusses is presented, which is applicable in wide range of scope and ground layers, convenient for construction, long durability, wide source of materials. mechanism for subgrade strengthening : complex foundation of cement solid and earth between piles was formed by pulsant load of flowing pressure and spraying flow, water wallop, cavitation phenomenon, water wedge effect, extrusion force and air flow agitation etc so as to enhance foundation bearing force and reduce settlement and deformation
高壓旋噴注漿技術具有適用范圍、適用地層較廣，施工方便，耐久性好，材料廣闊等特點；其加固地基機理主要是通過流動壓、噴射流的脈動負荷、水塊的沖擊力、空穴現象、水楔效應、擠壓力、氣流攪動等效應形成水泥固結體與樁間土的復合地基，從而提高地基承載力，減少沉降變形。Thaw settlement cause negative friction. this paper base on the thought of " initiative cooling ", aim at three problems existing in common concrete pile used in frozen soil, a new type of pile is proposed to overcome the disadvantages of the classical pile used in frozen soil. pile body within active layer is fluted and refilled with porous materials such as gravels and ballasts, convection will be occur and then thermal exchange inside porous material in winter while only heat conduction exists in summer, as a result the soil around flutings will be cooled, so the top line of permafrost will be drive up
本文基於「主動冷卻」地基的思想，以及針對凍土地區普通混凝土樁存在的三大問題，提出了一種新型樁的設計思路，運用數值模擬試驗手段對其冷卻機理與加固機理進行了系統研究，即在凍融活動層的深度范圍內，在混凝土樁身的表面刻槽，修築完時槽內填充碎石、塊石等多孔介質，通過外界大氣溫度的自然波動下多孔介質在冬季時存在的對流換熱機制，而在夏季只存在熱傳導，來達到主動冷卻樁周凍土和抬升凍土上限的目的。
