Problems solved by technology

[0002] With the development of society, the scale of building construction structure is getting bigger and bigger and more complex, and the support of building construction structure is also getting bigger and bigger. The support is generally installed on the concrete cap. After the seat is installed on the concrete cap, it is necessary to grout the middle part of the large support. The grouting efficiency is generally low during grouting, which affects the overall construction progress
At the same time, after the grouting, there are still technical problems such as the grouting is not dense and the grouting is not full, and the level of grouting is difficult to be guaranteed, which affects the overall quality of the support construction

example 1

[0035] Such as Figure 1-7 As shown, a large-scale support grouting device provided in this example includes a side form 3 installed on the concrete cap 1 and used to accommodate the poured high-strength mortar 4, and is set in the side form 3 for the opposite side form 3 The inner high-strength mortar 4 compacts the horizontal grouting formwork 2 .

[0036] The invention has the advantages of simple structure, scientific and reasonable design, convenient use, low operation difficulty, low grouting cost, low requirements on the grouting environment during the grouting process, fast grouting construction speed, good effect, high grouting efficiency, dense and full grouting level, which can effectively guarantee Grouting quality and overall progress of support installation.

example 2

[0038] Such as Figure 1-7 As shown, a large-scale support grouting device provided in this example includes a side form 3 installed on the concrete cap 1 and used to accommodate the poured high-strength mortar 4, and is set in the side form 3 for the opposite side form 3 The inner high-strength mortar 4 compacts the horizontal grouting formwork 2 . The side formwork 3 includes a square-shaped side formwork body 31, and side formwork installation plates 32 distributed around the bottom periphery of the side formwork body 31;

[0039] In this example, on the basis of Example 1, the specific structure of the side formwork 3 is optimized. The side formwork 3 includes a side formwork plate body 31 in the shape of a mouth, and a side formwork installation plate 32 distributed around the outer periphery of the bottom of the side formwork plate body 31. ; The side formwork mounting plate 32 is fixed on the concrete platform 1 through expansion bolts 33 . In this way, the side formw...

example 3

[0041] Such as Figure 1-7 As shown, a large-scale support grouting device provided in this example includes a side form 3 installed on the concrete cap 1 and used to accommodate the poured high-strength mortar 4 , and is set in the side form 3 for the opposite side form 3 The inner high-strength mortar 4 compacts the horizontal grouting formwork 2 . The side formwork 3 includes a square-shaped side formwork body 31, and side formwork installation plates 32 distributed around the bottom periphery of the side formwork body 31; The side formwork body 31 is distributed vertically, and the side formwork mounting plate 32 is distributed vertically to the side formwork body 31 .

[0042]On the basis of Example 2, this example optimizes the specific structure of the side formwork plate body 31 and the side formwork mounting plate 32, the side formwork plate body 31 is vertically distributed, and the side formwork mounting plate 32 is distributed vertically to the side formwork plate...

Abstract

The invention discloses a large support grouting device and a grouting method thereof. The technical problems that in the prior art, the grouting efficiency is low, grouting is not compact and full, and the levelness is insufficient are solved. The grouting device mainly comprises a side template and a grouting template. The grouting method is a secondary grouting method, during primary grouting, high-strength mortar is poured in a side formwork before the support is installed, then the high-strength mortar is pressed through a mud jacking formwork to achieve the high-strength mortar compact level, and after the strength of the high-strength mortar reaches the standard, the formwork is dismantled, the support is installed, and gravity type grouting is directly adopted in the secondary grouting process. The grouting device is simple in structure, scientific and reasonable in design, convenient to use, low in operation difficulty, low in grouting cost, low in grouting environment requirement in the grouting process, high in grouting construction speed, good in effect, high in grouting efficiency and compact, full and horizontal in grouting, and the grouting quality and the overall progress of support installation can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a large-scale bearing grouting device and a grouting method thereof. Background technique [0002] With the development of society, the scale of building construction structure is getting bigger and bigger and more complex, and the support of building construction structure is also getting bigger and bigger. The support is generally installed on the concrete cap. After the seat is installed on the concrete cap, it is necessary to grout the middle part of the large support. The grouting efficiency is generally low during grouting, which affects the overall construction progress. At the same time, after the grouting, there are still technical problems such as the grouting is not dense, the grouting is not full, and the level of grouting is difficult to be guaranteed, which affects the overall quality of the support construction. [0003] Therefore, the pres...
