Device for continuously pouring concrete at expansion joint of pavement and construction method
The invention relates to a device for continuously pouring concrete at a pavement expansion joint and a construction method. The device is mainly composed of an expansion joint plate, a caulking strip, an end formwork, a dowel bar, a sleeve, a steel bar support and a U-shaped groove. The positions of the dowel bars are fixed in advance through the steel bar supports, the caulking plates and the caulking strips at the expansion joints are fixed at the same time through the end formworks, and the caulking plates and the caulking strips are perpendicular to the middle line of a road, continuously penetrate through the width of the whole pavement slab and are firmly attached to form a whole, so that the problems that the expansion joint plates and the caulking strips are interfered by displacement in the pouring process, and slurry connection occurs are solved; the expansion function of the expansion joint is influenced; the U-shaped grooves in the end formworks can guarantee that the dowel bars can be smoothly pulled out after pouring is completed while the dowel bars are inserted, mounting and dismounting are convenient, reutilization can be achieved, gaps are filled with concrete and vibrated compactly, the purpose of continuous pouring of the two sides of expansion joints is achieved, the construction efficiency can be improved, construction joints are reduced, the pavement construction quality is improved, and the construction cost is reduced. The pavement service life is prolonged.
本发明涉及一种路面胀缝处连续浇筑混凝土的装置及施工方法。该装置主要由胀缝板、嵌缝条、端头模板、传力杆、套筒、钢筋支架及U型槽组成。通过钢筋支架提前固定传力杆位置，使用端头模板对设置胀缝处的嵌缝板及嵌缝条进行同时固定，并垂直于道路中线，连续贯通整条路面板宽度，牢牢贴合成一个整体，避免浇筑过程中，胀缝板和嵌缝条受到位移干扰，出现连浆问题，影响胀缝伸缩功能；端头模板上的U型槽能保证传力杆插入的同时，浇筑完成后能顺利抽出，安拆方便且能重复利用，空隙部分再填补混凝土，振捣密实，实现胀缝处两侧连续浇筑的目的，并能够提高施工效率，减少施工缝的产生，提高路面施工质量，延长路面使用寿命。
