Embodiment Construction

[0031] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] Such as Figure 1 ~ Figure 3 As shown, the construction method of the integral sliding of the pier wall belt connection beam of the present invention specifically comprises the following steps:

[0033] Step 1. Modify the sliding form device:

[0034] Step 1.1. Set the movable formwork at the junction of the connecting beam and the pier wall as the pier wall sliding formwork, use angle steel welding to make a cuboid truss, and use steel plate embedded welding to make the formwork plate surface of the sliding formwork;

[0035] Step 1.2. Set several hydraulic jacks on the cuboid truss according to the construction specification and building structure, and use channel steel to make several "open" and "F" shaped supports;

[0036] Step 1.3. Install "open" and "F"-shaped brackets on each hydraulic jack, and the hydr...

Abstract

The invention particularly relates to a construction method for integrally sliding and lifting a pier wall with a connecting beam. The method is as below: first of all, retrofitting a slip form device; manufacturing a connecting beam bottom die bracket; according to the positions of the connecting beam, dividing a connecting beam sliding-lifting mold body at the intersection position of the pier wall and the connecting beam; manufacturing a movable mold plate; building a connecting beam supporting structure; laying embedded parts on a connecting beam bottom mold plate; conducting concrete pouring; dismantling the movable mold plate; and adding a retarder into concrete poured between the connecting beam and the pier wall. The construction method has the following beneficial effects: the construction is safe, the quality and progress are reliable, staged pouring of the reserved beam nest is omitted, and the safety problem caused by scaffold construction in second-stage construction is avoided; the problems of rough surface treatment and warehousing vibration compaction of a narrow space of a beam nest caused by second-stage pouring are avoided; and the integrity of the second-stage pouring structure is improved.

Description

technical field [0001] The invention belongs to the technical field of construction in the hydropower industry, and in particular relates to a construction method for the integral sliding of a pier wall with a connecting beam. Background technique [0002] With the development of China's hydropower industry, especially the development of pumped storage power stations at home and abroad, the overall construction of the tower body of the inlet and outlet or the high-bracket pier wall belt of the trash rack is difficult, and the second-phase construction of the reserved beam has problems The structural integrity is not good, and there is a big risk in construction safety. [0003] For the above existing problems, the conventional method for the tower body of the water inlet and outlet or the high-bracket pier wall with the connecting beam is to use a wooden box to reserve a beam nest at the position of the connecting beam, and first use the slip-form construction technology to ...
