一、产品说明：
1. Product Description:
橡胶抽拔管是一种用于混凝土构件小直径成孔的新型芯默，它主要为桥梁上形成较小预应力孔而设计，也可用于其它建筑行业混凝土的成也。它是利用其高强度，高弹性和橡胶体积不可压缩性能，在抽拔管内不加任何骨架材料，在管体轴向受力时，即会轴向伸长，径向自然弯细，使管体和混凝土也壁出现向隙而逐步剥离拉出。抽拔有力，施工方便，可反复使用，寿命长，表面光滑，平整度好，预留孔孔壁光滑，且抽拔时向不受混凝土凝固时内的限制，经济效益是显而易见的。
Rubber extractive pipe is a new core for small diameter concrete members. It is mainly designed for forming smaller prestressed holes on bridges, and also for building concrete in other construction industries. It uses its high strength, high elasticity and incompressibility of rubber volume, and does not add any skeleton material in the drawing pipe. When the tube body is subjected to axial force, it will extend axially and naturally radiate naturally, so that the tube body and concrete wall will be released to the gap gradually. Pull strong, construction is convenient, can be used repeatedly, long service life, smooth surface, good flatness, the reserved hole wall is smooth, and withdrawing from the concrete to the solidification within the limits of economic benefit is obviously.

该产品主要用于各种规格的钢筋混凝土构件成孔，包括桩、屋架、屋面板、柱、梁、墙板等构件成孔的新型工程橡胶制品。橡胶抽拔管与传统使用的钢质波纹管相比，具有无可比拟的优点，即施工装卸灵活、结构简单、造价低廉和能够重复使用等特点。可用于直径50～90mm的混凝构件的成孔，使用温度在-10～80℃的范围，特别适用于后张紧预应力桥梁的抽孔，它可使混凝土构件施工简便，抽孔快速，质量好，并能节约大量三材和劳力。橡胶抽拔管与其他橡胶制品相比，其技术难点在于挤出橡胶制品需具有良好的弹性和伸长率，且硫化是在高温低压下进行，无模具，这就需要在配方设计和工艺设计上要达到较高水平。
The product is mainly used for various specifications of reinforced concrete members, including pile, roof truss, roof panels, columns, beams, wall panels and other components of the new type of engineering rubber products. Compared with the traditional steel bellows, the rubber extractive pipe has many advantages compared with the traditional steel bellows, such as flexible construction, loading and unloading, simple structure, low cost and repeated use. It can be used for pore forming of 50 ~ 90mm diameter concrete components. The temperature range from -10 to 80 C is especially suitable for pumping holes of post tensioned prestressed bridges. It can make concrete components easy to construct, fast and fast, and can save a lot of three materials and labor. Compared with other rubber products, the technical difficulty of rubber drawn pipes is that the extruded rubber products need to have good elasticity and elongation, and vulcanization is carried out at high temperature and low pressure without mold. This requires a high level in formulation design and process design.
产品已应用到北京城建一公司三灵高速公路6标、中铁十九局集团包西通道施工、广东省交通厅公路工程局三灵高速公路5标、湖南省长沙建筑三公司等多项工程中，受到广大客户的青睐和好评。
The product has been applied to the Beijing urban construction company Sanling Highway 6, China Railway Group nineteen channel construction, including the West Hall of Guangdong Province Traffic Highway Engineering Bureau of Hunan Province, the sanmenxia-lingbao Expressway 5 Changsha building three companies and many other projects, favored by the majority of customers and praise.
