Abstract

本实用新型涉及一种干湿两用拨料管,所述拨料管有内套管(1)和外套管(2)构成,所述外套管(2)由混凝土构成,所述内套管(1)由聚氨酯构成。本实用新型干湿两用拨料管,具有耐腐蚀性能好的特点。

Description

干湿两用拨料管
技术领域
本实用新型涉及一种拨料管,尤其是涉及一种用于混凝土喷射机上的可干湿两用的拨料管。
背景技术
目前,在混凝土喷射机上的拨料管,通常使用单一材质构成,如混凝土,这类结构的拨料管往往耐腐蚀性较差,长时间使用后,由混凝土构成的拨料管容易发生渗漏的情况。
发明内容
本实用新型的目的在于克服上述不足,提供一种耐腐蚀性能好的干湿两用拨料管。
本实用新型的目的是这样实现的:一种干湿两用拨料管,所述拨料管有内套管和外套管构成,所述外套管由混凝土构成,所述内套管由聚氨酯构成。
与现有技术相比,本实用新型的有益效果是:
本实用新型由于在混凝土构成的外套内套装了由聚氨酯构成的内套,聚氨酯具有较高的耐腐蚀性,因而能够显著提高本实用新型拨料管的耐腐蚀性能。
附图说明
图1为本实用新型干湿两用拨料管的结构示意图。
其中:
内套管1、外套管2。
具体实施方式
参见图1,本实用新型涉及的一种干湿两用拨料管,所述拨料管有内套管1和外套管2构成,所述外套管2由混凝土构成,所述内套管1由聚氨酯构成。
使用时,由混凝土构成的外套管2提供支撑力,由聚氨酯构成的内套管1附着在外套管2的内表面,内套管1内填充待喷射的混凝土浆料,由于聚氨酯具有较高的耐腐蚀性,因而能够显著提高拨料管的耐腐蚀性。
