Problems solved by technology

However, for some construction environments or construction requirements, such as the construction environment where the embedded parts are large-area slabs, it is not convenient to further process the concrete pouring body, so the secondary grouting of grouting materials in the later stage often cannot obtain ideal filling quality. ; Some construction occasions have special requirements for engineering design, only one-time pouring of construction equipment foundation is allowed

Embodiment 1

[0031] The combined construction method of grouting material and concrete at the bottom of the embedded part is used for grouting construction at the bottom of the plate embedded part. Before the grouting material is poured, a plurality of grouting holes are set on the plate embedded part, and the grouting holes all penetrate the plate For embedded parts, the grouting holes are arranged sequentially from one side of the plate embedded part to the other side, and the one side and the other side are a pair of opposite sides;

[0032] The grouting hole is used as a channel for pouring grouting material to the bottom of the plate embedded part;

[0033] Grouting with grouting holes is carried out in the following ways:

[0034] The grouting material is poured within one hour to two hours after concrete pouring;

[0035] The grouting material is poured from one side of the plate embedded part to the other side, and the grouting material is poured into the space at the bottom of th...

Embodiment 2

[0040] This embodiment is further limited on the basis of Example 1: in order to further facilitate the flow of the grouting material at the bottom of the plate embedded part and obtain a larger grouting area, before the grouting material is poured, a plurality of Vent holes, the vent holes all go through the plate embedded part, and the vent holes are arranged in sequence from one side of the plate embedded part to the other side, and the vent holes are used as the bottom air of the plate embedded part to overflow outward channel;

[0041] There are vent holes between two adjacent grouting holes;

[0042] Vents are provided on both sides of the line connecting two adjacent grouting holes. In this scheme, the exhaust holes provided between the two adjacent grouting holes are not limited to the corresponding exhaust holes being located on the line connecting the corresponding two grouting holes; This situation is: the vent hole between two adjacent grouting holes is: the proj...

Embodiment 3

[0054] On the basis of Example 1, this embodiment provides a specific grouting material pouring construction method: before grouting, set up on the plate embedded parts The holes serve as vents and open The holes are used as grouting holes, and the grouting holes are arranged sequentially from north to south on the plate embedded parts. Cut notches on the plate embedded parts and the reinforcement ribs at the bottom of the plate embedded parts to facilitate the flow of grouting materials. An operating platform is set up on the upper part of the plate embedded parts. DN50 grouting pipes are installed below, and the high head difference and grouting material self-flowing method are used to facilitate the grouting from north to south --- if the numbers of grouting holes from north to south are 1, 2, 3, ... Grout through the No. 1 grouting hole, and then carry out the No. 2 grouting hole grouting, and then carry out the No. 3 grouting hole grouting, and complete the grouting of...

Abstract

The invention discloses an embedded part bottom grouting material and concrete combined construction method. The method is used for grouting construction of grouting materials at the bottom of an embedded plate part. Before grouting of the grouting materials, a plurality of grouting holes are formed in the embedded plate part, and the grouting holes are sequentially distributed from one side to the other side of the embedded plate part; grouting of the grouting materials is conducted through the grouting holes according to the following modes that grouting of the grouting materials is conducted in one to two hours after pouring of concrete; grouting of the grouting materials is conducted from one side to the other side of the embedded plate part, and the grouting materials sequentially pass through all the grouting holes, so that the bottom space of the embedded plate part is grouted with the grouting materials; and grouting of the currently grouted grouting hole is completed when thegrouting materials overflow from the grouting hole behind the currently grouted grouting hole, and then grouting of the grouting hole behind the currently grouted grouting hole is conducted until grouting of all the grouting holes is completed. One-time pouring construction of concrete and the grouting materials to the lower portion of the large embedded plate part can be achieved, a grouting material layer is closely combined with the embedded part, and cracks are not prone to occurring.

Description

technical field [0001] The invention relates to the technical field of embedded parts construction, in particular to a combined construction method of grouting material at the bottom of embedded parts and concrete. Background technique [0002] Usually, the gap filling method between the bottom of the embedded parts and the concrete foundation is secondary grouting construction, so as to meet the requirements that the concrete should be in close contact with the bottom plate and transmit the load evenly. However, for some construction environments or construction requirements, such as the construction environment where the embedded parts are large-area slabs, it is not convenient to further process the concrete pouring body, so the secondary grouting of grouting materials in the later stage often cannot obtain ideal filling quality. ; Due to the special requirements of engineering design in some construction occasions, only one-time pouring of construction equipment foundati...
