PRODUCT INTRODUCTION

下水井鋼模具大致說明是由幾塊鋼模板組裝而成的模具，全部使用鋼材料制作，結實耐用，適合用于混凝土檢查井的大批量生產。但同時由于下水井鋼模具是鋼材質的，使用時就需要更注意模具的保護和施工人員的操作安全。具體施工方法將在下面進行介紹：設置專人記錄和保存模具，進行定期的檢查和保養(yǎng)，以保證投入使用的模具的質量，如果發(fā)現問題需要及時記錄并送修；工人施工時應戴好手套和安全帽，配備專業(yè)服裝，時刻注意自己的人身安全；施工時應按照先組裝模具、擰緊螺栓，再在模具內刷油、灌漿的步驟操作，注意預制下水井模具   公路下水井模具是上下通透的，所以在放置時就要放在適合風干混凝土的位置上，一旦灌漿就不可以再作移動，先放模具的外模，再放內模以保證準確控制壁厚均勻；灌漿后要插入振動棒充分震動，把混凝土中的氣泡趕出以增強整個下水井鋼模具的密度。灌漿后靜靜等待一到兩天即可拆模，注意拆模時需要擰開連接處的螺絲，先拆掉內模上較小的那塊契型鋼板，再拆剩下的兩塊較大的鋼板和外模。The steel mould of the lower well is roughly described as a mould assembled from several steel formworks. All of them are made of steel materials, which is strong and durable and suitable for mass production of concrete inspection wells. But at the same time, because the steel mould of the lower well is made of steel, more attention should be paid to the protection of the mould and the operation safety of the construction personnel. The specific construction methods will be introduced below: assign special personnel to record and store the molds, and conduct regular inspection and maintenance to ensure the quality of the molds put into use. If problems are found, they need to be recorded and sent for repair in time; Workers shall wear gloves, safety helmets, professional clothes and pay attention to their personal safety at all times during construction; During construction, the steps of assembling the mold, tightening the bolts, and then painting and grouting in the mold shall be followed. It shall be noted that the prefabricated water well mold and the highway water well mold are transparent from top to bottom. Therefore, they shall be placed at the position suitable for air-dried concrete. Once grouting is completed, they can not be moved. The outer mold shall be placed first, and then the inner mold shall be placed to ensure accurate control of uniform wall thickness; After grouting, a vibrating rod shall be inserted to fully vibrate and drive out the bubbles in the concrete to enhance the density of the steel mold of the whole water well. After grouting, wait quietly for one to two days to remove the formwork. Note that the screws at the joint need to be unscrewed during formwork removal. First remove the smaller wedge-shaped steel plate on the inner formwork, and then remove the remaining two larger steel plates and the outer formwork.
