Rock foundation upper brake bottom horizontal wide seam and filling components

Abstract

The invention relates to a rock foundation upper brake bottom horizontal wide seam and filling components. The rock foundation upper brake bottom horizontal wide seam and the filling components are characterized in that a water brake bottom on a rock foundation is composed of bottom foundation rock (7), a concrete leveling layer (6), the wide seam (4), an interface agent (5) and a brake bottom plate (2), the concrete leveling layer (6) is laid on the bottom foundation rock (7), the concrete leveling layer (6) is brushed with the interface agent (5), the wide seam (4) is arranged between the concrete leveling layer (6) and the brake bottom plate (2), the inner portion of the wide seam (4) is filled with the composite filling components, a composite material (42) is arranged on the composite filling component, geogrids (43) are arranged in the composite material (42), a rubber layer (41) is arranged on the upper surface of the composite material (42), a rubber cushion (44) is arranged on the lower surface of the composite material (42), and the upper portion of the composite material (42) is connected with the brake bottom plate (2). The rock foundation upper brake bottom horizontal wide seam and the filling components are beneficial to industrial production and high in construction efficiency, and cracks on a water brake can be effectively prevented or reduced.

Description

technical field [0001] The invention relates to the technical field of filling horizontal wide cracks at the bottom of gates on rock foundations, in particular to a horizontal wide cracks at the bottom of gates on rock foundations and a filling component. Background technique [0002] In the sluice design and construction specifications, the sluice built on the rock foundation does not allow a joint between the bottom plate and the rock foundation, and the seam needs to be chiseled and filled during construction. The operation practice shows that after the floor concrete and the bedrock are connected as a whole, due to the constraints of the bedrock on the floor concrete, etc., the floor and gate piers are prone to cracks, which seriously affects the safe operation of the sluice. In the arch dam design specification, contact joints, that is, peripheral joints, can be set between the arch dam and the riverbed and bank concrete cushion. In the design of earthquake-resistant ...

Problems solved by technology

[0003] The purpose of the present invention is to effectively solve the problem of bed rock constraining the concrete floor, and provide a technology for water gates to overcome bed rock constraints, that is, a horizontal wide crack at the bottom of the gate on the rock base and a filling member

The seam width setting is generally 20mm
