Expandable anode assembly
An array of anode assemblies for insertion at a plurality of locations in a gap between a section of a reinforced concrete structure and another solid structure is provided. Each anode assembly comprises an expandable member, an anode attached to the expandable member for protecting a steel reinforcement in the reinforced concrete structure, and an anode connector for interconnecting the array of anode assemblies. During use, each anode assembly of the array of anode assemblies is inserted into the gap, between the section of the reinforced concrete structure and the solid structure, at the plurality of locations. The expandable member of each anode assembly is configured to expand so as to press the anode into contact with a surface of the reinforced concrete structure.
Method and assembly for making a concrete expansion joint insert
An illustrative example embodiment of an assembly for making a concrete expansion joint insert includes an extruder a device that receives material from the extruder. The device includes a flow path through the device and at least one internal feature that directs the material away from a middle of the flow path and toward outside edges of the flow path to establish an approximately equal flow rate of the material through the middle and outside edges of the flow path.

Method for Relieving Vaulted Expansion of Cement-Stabilized Base Layer Through Precut Seams
The present invention discloses a method for relieving vaulted expansion of a cement-stabilized base layer through precut seams. The method firstly establishes an RBFN model according to a large number of observation results of a vaulted expansion amount of the cement-stabilized base layer under different conditions (such as temperature and a stress release structure) in Xinjiang and similar regions; and on such a basis, the vaulted expansion amount of the cement-stabilized base layer to be designed is predicted. When the vaulted expansion amount is greater than a control requirement, the RBFN model is configured to design a reasonable width and a reasonable interval of the precut wide expansion seams to ensure that the vaulted expansion amount of the cement-stabilized base layer is less than a control value. Based on the design of the RBFN model, the present invention provides a corresponding construction method for the precut wide expansion seams. The present invention can predict the vaulted expansion of the cement-stabilized base layer without precut seams according to existing data.
