Embodiment Construction

[0020] like figure 1 Shown, the present invention is achieved in that a kind of frame structure water pump house foundation construction method comprises the following steps:

[0021] a. Set out the frame foundation 1 of the pump house, excavate the foundation pit of the frame foundation 1, and keep the soil layer in the middle of the frame without excavation.

[0022] b. The frame foundation 1 is constructed in the foundation pit, and the frame foundation 1 is maintained until the formwork is removed.

[0023] c. The soil layer of the frame foundation 1 is rammed and filled in layers, and the backfill height of the soil layer is below the ground beam 2 and below the indoor floor structure layer.

[0024] d. The foundation pit of the equipment foundation 4 is excavated, the foundation pit of the equipment foundation 4 is manually trimmed, and the soil wall of the foundation pit of the equipment foundation 4 is used as a soil mold for pouring construction.

[0025] e. Set up ...

Abstract

The invention relates to a construction method for a water pump house foundation of a frame structure. The method comprises the steps of (a) conducting setting out on the water pump house frame foundation, excavating a foundation pit of the frame foundation and reserving a soil layer at the middle part of the frame without excavation; (b) constructing the frame foundation in the foundation pit, and conducting conservation of the frame foundation till form removal; (c) conducting layered compaction and filling of the soil layer of the frame foundation, wherein a backfilling height of the soil layer is lower than a ground beam and lower than an indoor terrace structural layer; (d) excavating a foundation pit of an equipment foundation, wherein pouring condition of the equipment foundation iscarried out with a soil wall of the foundation pit as a soil model; (e) erecting a scaffold of an upper frame structure and constructing the upper frame structure; (f) constructing ground beams around the frame structure; and (g) constructing a water pump house maintenance structure. The construction method provided by the invention changes a traditional construction mode for a frame-structure water pump house; a construction period of a whole construction course is greatly shortened; compaction quality of the ground can be ensured; and a collapse accident which happens after water leakage can be prevented.

Description

technical field [0001] The invention relates to a construction method of a water pump house, in particular to a foundation construction method of a frame structure water pump house. Background technique [0002] The water pump room is a key part of providing water for living, production and fire fighting. The number of equipment in the water pump room is large and dense. In the construction of the traditional concrete frame structure water pump room, due to the dense foundation layout, the frame foundation and the equipment foundation are generally arranged to be synchronized. Construction, earthwork construction adopts a large-scale excavation plan. First, all the earthwork within the frame of the pump room is excavated. The concrete foundation is constructed sequentially from deep to shallow. After all the concrete is completed, the pores between the foundations are backfilled under the floor. . This results in a relatively large amount of earth excavation and filling, an...
