Embodiment Construction
[0046] Example of installation method for base plate of static equipment in petrochemical industry
[0047] This embodiment is the installation method of the base plate of the vertical cylindrical chemical reactor equipment with a skirt. The equipment weighs 10 tons in 5 pieces and is equipped with 8 anchor bolts of M24.
[0048] I. Making concrete base
[0049] According to the design and construction drawings, pour the cylindrical concrete base 1 according to the size of the base of the equipment 5, and install the vertical anchor bolts 4; the sides of the concrete base 1 are 50mm larger than the sides of the base of the equipment 5;
[0050] II. Making the backing plate
[0051] In this example, a concrete pier 2 is arranged every two anchor bolts 4 . A total of 4 concrete piers 2 are used to make 4 backing plates 3 .
[0052] Calculate the area A of the single backing plate 3 according to the following formula
[0053] A≥C×(Q1+Q2) / R
[0054] In the formula: A - the mini...

The invention discloses a method for mounting seat pulp cushion plates of petrochemical static equipment and a foundation structure. The method includes that a plurality of concrete piers with cushion plates are manufactured on a concrete base, the minimum area of each single cushion plate is computed according to the sum of the weight of the equipment and pre-tightening force of anchor bolts, load added on the cushion plate and compressive strength of selective concrete, the concrete piers are trapezoidal tables, the seat pulp cushion plates are arranged on tops of the concrete piers, and surfaces of the cushion plates are positioned on the same horizontal plane. The equipment is seated on the cushion plates of the concrete piers by means of hoisting, and the various anchor bolts are fastened. A secondary grouting layer is formed by means of secondary grouting for a space between the bottom of the equipment and the concrete base. The trapezoidal table concrete piers which are positioned below a reinforcing plate of the equipment are arranged on the concrete base of the foundation structure, the cushion plates are disposed on the tops of the piers, and the surfaces of the cushion plates of the piers are positioned on the same horizontal plane. The secondary grouting layer is disposed between the bottom of the equipment and the concrete base. The method and the foundation structure have the advantages that wedge liners are omitted, materials are saved, the cushion plates of the concrete piers are integrally connected with the base, installation is carried out conveniently, installation quality is improved, and installation work period is shortened.
Description
(1) Technical field [0001] The invention relates to the installation technology of petrochemical static equipment, in particular to an installation method and a basic structure of a base plate of petrochemical static equipment. (2) Background technology [0002] Large-scale static equipment, such as petrochemical towers, reactors and other static equipment, has a high body and heavy weight, and requires high verticality and stability. Therefore, its installation requirements are high. "Code for Construction Quality Acceptance of Petrochemical Static Equipment Installation Engineering" (GB50461-2008) only mentions two installation and construction methods for equipment installation: one is installation with shim iron, and the other is installation without shim iron. For the installation of shims, a large number of flat shims and slanted shims must be produced first, and the processing cost is high. During the installation of shims, the adjustment is time-consuming and labori...
