ZHENG CHAO / CHEN KANGXU / WANG JIAN / HU HUAN / RONG SHISHENG

The invention discloses roadbed repairing equipment and method for road construction, and belongs to the technical field of road repairing equipment. The roadbed repairing equipment comprises a bottom plate, a drilling and grouting mechanism, an adjusting mechanism, a water spraying mechanism and a grout storage mechanism. According to the roadbed repairing equipment for road construction, the drilling and grouting mechanism, the adjusting mechanism, the water spraying mechanism and the slurry storage mechanism are arranged, a pavement surface layer is drilled through cooperation of the drilling and grouting mechanism and the adjusting mechanism, so that part of the drilling and grouting mechanism is located in a roadbed, then the slurry storage mechanism is connected with the drilling and grouting mechanism, and the grouting mechanism is connected with the adjusting mechanism; cement paste is injected into the roadbed through the drilling and grouting mechanism, and efficient repairing of the slab bottom void is achieved; in the drilling process, water is sprayed to the drill bit through the water spraying mechanism, the temperature of the drill bit during drilling is effectively reduced, the service life of the drill bit is prolonged, and meanwhile equipment faults possibly caused by high temperature are reduced.

本发明公开了一种道路施工用路基修复设备及方法，属于道路修护设备技术领域，包括底板、钻孔注浆机构、调节机构、喷水机构和浆液存放机构。本发明中的道路施工用路基修复设备通过设置钻孔注浆机构、调节机构、喷水机构和浆液存放机构，通过钻孔注浆机构和调节机构的配合对路面面层进行钻进，使钻孔注浆机构的部分处于路基内，然后，将浆液存放机构与钻孔注浆机构连接，并通过钻孔注浆机构向路基内注入水泥浆，实现了对板底脱空的高效修复；在钻孔过程中通过喷水机构向钻头喷射水，有效降低了钻头在钻进时的温度，提高了钻头的使用寿命，同时也减少了因高温可能引发的设备故障。
