Abstract
The invention relates to a basement wall plate and containment support changing system and a construction method. The system comprises a latticed column, a foundation bottom plate, a first path concrete support and an underground two-layered top plate, wherein the foundation bottom plate is connected with the first path concrete support through the latticed column in a supporting manner; and an underground two-layered wall plate is supported by containment at the two sides; and a bentonite waterproof carpet and an extruding polyphenyl plate heat-preservation layer are paved between the containment and the underground two-layered wall plate. The basement wall plate and containment support changing system is a novel support changing system which combines a basement structure outer wall plate to form a framework type combined support to commonly resist lateral force of the structure. The basement wall plate and containment support changing system adopts a basement structure outer wall plate so that the working amount of the backfilling construction of a foundation pit is reduced and the removing construction period of a template of an outer wall plate structure is saved. The basement structure outer wall plate and the newly-established support are combined to be stressed so that the rigidity and the stability of support changing are enhanced.
Description
Technical field
The present invention relates to a kind of job practices that adopts the basement wall to replace support-replacing system, be applicable to the closely spaced support replacement construction of core city foundation pit system and underground space structure.
Background technology
During conventional Underground Construction, because floor lacks less, spatial extent is little, only can satisfy the support replacement requirement at corresponding site construction reinforced bar concrete beam or section steel beam.In underground large spatial structure construction; structure floor disappearance area is large, story height is high, spatial extent is large; common beam type support replacement all is difficult to guarantee the reasonable stressed and construction safety of support replacement from intensity, rigidity and stable equal angles; and underground space structure and pit maintenance soil system spacing are little, and trouble, construction period prolongation but also cost are high if construction beam type support replacement is not only constructed.Support replacement belongs to temporary support structure, if can adopt novel support-replacing system, guaranteeing prerequisite decline low cost, the quickening progress of construction safety, then can create good economic benefit.
Summary of the invention
The present invention need to solve the underground large spatial structure construction stage, can't constructing technology problem because of original beam type support replacement, the support-replacing system that provides a kind of employing to have sufficient intensity, rigidity and stability guarantees that underground structure can resist double support-replacing system and the job practices gone along with sb. to guard him of basement wallboard of the lateral force that water and soil applies voluntarily at fininshing step not.
Technical scheme of the present invention is: the double support-replacing system of going along with sb. to guard him of a kind of basement wallboard, comprise that lattice column, sole plate, first concrete support, underground two layers of top board, between supporting, sole plate and first concrete pass through the lattice column support and connection, two sides are with going along with sb. to guard him the underground two layers of wallboard of support replacement, and go along with sb. to guard him and underground two layers of wallboard between lay GCL and extruded polystyrene board insulation layer.
The double job practices of going along with sb. to guard him support-replacing system of a kind of basement wallboard, concrete steps are:
1) reaches in the designing requirement situation in sole plate intensity, remove the second concrete and support the paving of extruded polystyrene board insulation layer;
2) after the paving of extruded polystyrene board insulation layer is finished, underground two layers of exterior wall GCL construction;
3) underground two layers of wallboard and go along with sb. to guard him support replacement construction;
4) repeating step 1) and step 2) and step 3), until form the double support-replacing system of going along with sb. to guard him of basement wallboard.
The invention has the beneficial effects as follows:
The present invention adopts novel support-replacing system cancellation previous level to support and job practices, the thickening of basement structure outer wall plate is extended to foundation pit system consist of firm space frame system, opposing side direction horizontal power.
Double rigidity and the stability that support-replacing system has increased support-replacing system greatly, the more reasonable stress gone along with sb. to guard him of basement wallboard; Save time and the cost of support replacement construction, reduce engineering quantity and the cost of pit backfill soil, have extraordinary economic benefit.

Fig. 1 is extruded polystyrene board insulation layer paving construction schematic diagram;
Fig. 2 is underground two layers of exterior wall GCL construction schematic diagram;
Fig. 3 is structure of the present invention and underground two layers of wallboard and goes along with sb. to guard him support replacement construction schematic diagram.
The specific embodiment
As shown in Figure 3, the double support-replacing system of going along with sb. to guard him of basement wallboard of the present invention comprises that lattice column 1, sole plate 2, first concrete support 3, go along with sb. to guard him 6, underground two layers of top board 7, GCL 5 and extruded polystyrene board insulation layer 4.
By lattice column 1 support and connection, two sides were with going along with sb. to guard him the underground two layers of wallboard of 6 support replacements between sole plate 2 and first concrete supported 3, and go along with sb. to guard him 6 and underground two layers of wallboard between laying GCL 5 and extruded polystyrene board insulation layer 4.
The double job practices of going along with sb. to guard him support-replacing system of basement wallboard, concrete steps are:
1) reaches in the designing requirement situation in sole plate 2 intensity, remove the second concrete and support 8, paving extruded polystyrene board insulation layer 4(Fig. 1 `);
2) after 4 pavings of extruded polystyrene board insulation layer are finished, underground two layers of exterior wall GCL, 5 constructions (Fig. 2);
3) underground two layers of wallboard and go along with sb. to guard him 6 support replacements construction (Fig. 3);
4) repeating step 1) and step 2) and step 3), until form the double support-replacing system of going along with sb. to guard him of basement wallboard.
The double support-replacing system of going along with sb. to guard him of basement wallboard is a kind of newly-built support replacement forms the common resisting structure lateral force of frame type combined support in conjunction with the basement structure side fascia novel support-replacing system.Its utilized the basement structure outer wall plate, not only reduced pit backfill construction working amount, but also saved the dismounting external wall panel structure form removable construction period.The basement structure outer wall plate is combined stressed with newly-built support, increased again rigidity and the stability of support replacement.
