強夯(hang)法的(de)施(shi)(shi)工主要包括施(shi)(shi)工機具和施(shi)(shi)工要點。隨著強夯(hang)技術的(de)不斷發(fa)展(zhan)，施(shi)(shi)工機具由初期的(de)小型或自制設備逐(zhu)步(bu)發(fa)展(zhan)到大型的(de)設備，而且施(shi)(shi)工方法也逐(zhu)漸(jian)成熟，公路強夯(hang)地(di)基(ji)施(shi)(shi)工，加固效果更(geng)加顯著。

1. 施工機具

1) 履(lv)帶式(shi)吊(diao)車。一般采用15t—50t履(lv)帶式(shi)吊(diao)車。

2) 夯(hang)錘。夯(hang)錘質(zhi)量可(ke)取10—40t，其底(di)面(mian)形(xing)式宜(yi)采用圓型。錘底(di)面(mian)積宜(yi)按土(tu)的(de)性質(zhi)確定，錘底(di)靜(jing)接(jie)地壓力值(zhi)可(ke)取25—40Kpa，對于細顆粒土(tu)錘底(di)靜(jing)壓力宜(yi)取較(jiao)小值(zhi)。錘的(de)底(di)面(mian)應對稱設置若(ruo)干個與其頂(ding)面(mian)貫通的(de)排氣孔，孔徑可(ke)取250—300mm。

3) 脫(tuo)鉤裝(zhuang)置。采用的自(zi)動脫(tuo)鉤裝(zhuang)置，規格以滿足起吊夯錘重(zhong)量(liang)為(wei)宜。

4) 推土(tu)機(ji)。采用70—220型履帶(dai)式(shi)推土(tu)機(ji)。

2． 施工要點

1）強夯施(shi)(shi)工前，應(ying)查明(ming)場地(di)范圍(wei)內的地(di)下構建物(wu)和各種地(di)下管(guan)線的位置和標高等，并采(cai)取必要(yao)措施(shi)(shi)，以免因強夯施(shi)(shi)工而造成破壞(huai)。

2) 當強夯施(shi)工所(suo)產生(sheng)的(de)振(zhen)動(dong)，對鄰近建筑物或設備產生(sheng)有害影(ying)響時，應(ying)采取防振(zhen)或隔(ge)振(zhen)措施(shi)。

3）平整施工場地，測量，記錄場地的高程。

 4）起重機就位，對(dui)準(zhun)夯點位置，測量，記錄夯前錘頂(ding)高(gao)程。
